1.3 Caution: Aerial Load

The equipment has been designed to operate safely under a wide range of aerial loading

conditions. However, we strongly recommend that the transmitter should always be

operated with a suitable load to prevent damage to the transmitter output power stage.

1.4 Caution: Beryllium Oxide and Power Transistors

The RF power transistors in current use all contain some beryllium oxide. This sub-

stance, while perfectly harmless in its normal solid form, can become a severe health

hazard when it has been reduced to dust. For this reason the RF power transistors

should not be broken open, mutilated, filed, machined, or physically damaged in any

way that can produce dust particles.

2.1 Torx Recess Head Screws

Torx recess head screws are becoming the standard screw head type in all T800 SL2

equipment, with Pozidriv and Philips recess head screws being used in fewer applica-

tions.

The Torx recess head has the advantage of improved screwdriver tip location, reducing

the chances of screw head damage caused by the driver tip rotating within the recess. In

addition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw with

the driver on a slight angle, which can be useful in situations where access is restricted.

It is important that you use the correct Torx screwdriver tip:

M3 screws T10

M4 screws T20

Figure 2.1 below shows a typical Torx recess head screw (actual hardware may differ

slightly from this illustration due to variations in manufacturing techniques).

A2.2 Mechanical M8SL2-00-002-812

2.2 Pozidriv and Philips Recess Head Screws

Pozidriv and Philips recess head screws will continue to be used in T800 SL2 equipment

in a few special applications. It is important that you use the correct type and size

screwdriver for each screw type to avoid damaging the screw head.

It is particularly important that you do not use Philips screwdrivers on Pozidriv screw

heads as the tapered driving flutes of the Philips screwdriver do not engage correctly

with the parallel-sided slots in the Pozidriv screw head. This can result in considerable

damage to the screw head if the screwdriver tip turns inside the recess.

Note: If you find you need excessive downwards pressure to keep the screwdriver

tip in the Pozidriv screw head, you are probably using the wrong type and/

or size screwdriver.

Figure 2.2 below shows the main differences between typical Pozidriv and Philips screw

heads and screwdriver tips (actual hardware may differ slightly from these illustrations

due to variations in manufacturing techniques).

2.3.1 Receivers/Transmitters

To carry out alignment or change option links, you need to remove only the top cover,

i.e. the one on the opposite side to the main D-range connector (D-range 1/PL100).

You need to remove the bottom cover to:

• access transmitter RF power transistors and many SMD components

• change solder blob links

• fit test leads to circuit block access points.

3.1 Leaded Components

Whenever you are doing any work on the PCB that involves removing or fitting compo-

nents, you must take care not to damage the copper tracks. The two satisfactory meth-

ods of removing components from plated-through hole (PTH) PCBs are detailed below.

Note: The first method requires the use of a desoldering station, e.g. Philips SBC

314 or Pace MBT-100E.

3.1.1 Desoldering Iron Method

Place the tip over the lead and, as the solder starts to melt, move the tip in a circu-

lar motion.

Start the suction and continue the movement until 3 or 4 circles have been com-

pleted.

Remove the tip while continuing suction to ensure that all solder is removed from

the joint, then stop the suction.

Before pulling the lead out, ensure it is not stuck to the plating.

If the lead is still not free, resolder the joint and try again.

Note: The desoldering iron does not usually have enough heat to desolder leads

from the ground plane. Additional heat may be applied by holding a solder-

ing iron on the tip of the desoldering iron (this may require some additional

help).

3.1.2 Component Cutting Method

Cut the leads on the component side of the PCB.

Heat the solder joint sufficiently to allow easy removal of the lead by drawing it

out from the component side: do not use undue force.

Fill the hole with solder and then clear with solderwick.

A3.2 Component Replacement M8SL2-00-002-812

3.2 Surface Mount Devices

Caution: Surface mount devices (SMDs) require special storage, handling,

removal and replacement techniques. This equipment should be serv-

iced only by an approved Tait Dealer or Customer Service Organisa-

tion equipped with the necessary facilities. Repairs attempted with

incorrect equipment or by untrained personnel may result in perma-

nent damage. If in doubt, contact your nearest Tait Dealer or Customer

Service Organisation.

3.3 Cased Mica Capacitors

Cased mica capacitors can be removed by heating the top with a heavy-duty soldering

iron and gently lifting the capacitor off the PCB with a solder-resistant spike or equiva-

lent.

M8SL2-00-002-812 T855 General Information B1.5

1.1 Introduction

The T855 is a high performance microprocessor controlled FM base station receiver

designed for single or multichannel operation in the 400 to 530MHz frequency range1.

The receiver is a dual conversion superhet with a synthesised local oscillator. The first IF

is 45.0MHz, allowing exceptionally high spurious signal rejection to be achieved in the

receiver front end. The second IF section (455kHz) combines amplitude limiting, detec-

tion and audio preamplification within a single integrated circuit. It also drives carrier

and noise level detectors for signal strength indication and gating the audio output.

RSSI can be used to drive a carrier mute for audio output gating (link selectable) when

the optional T800-04-0000 RSSI PCB is fitted.

The audio section output can be adjusted to deliver >+10dBm to a 600Ω balanced out-

put, and 1W to a local monitor speaker. A flat or de-emphasised audio response is link

selectable.

The synthesiser frequency is programmed via the serial communications port. Eight

channel select lines are accessible via an additional D-range connector (D-range 2 –

T800-03-0000) at the rear of the set.

All components except those on the VCO board are mounted on a single PCB. This is

secured to a die-cast chassis which is divided into compartments to individually shield

each section of circuitry. Access to both sides of the main PCB is obtained by removing

each of the two chassis covers. There is provision within the chassis to mount small

option PCBs.

The front panel controls include gating sensitivity, line level, monitor volume and a

monitor mute switch.

1. Although capable of operating over the 400 to 530MHz frequency range, the T855 has a

5MHz switching range (see Section 1.2.3 and Section 3.1).

2.2 Receiver Front End

(Refer to the front end, IF section and audio processor circuit diagrams (sheets 4, 3 and 2

respectively) in Section 6.3.)

Figure 2.2 T855 Front End, IF and Mute Block Diagram

The incoming signal from the N-type antenna socket is fed through a 9-pole, low pass

filter with a cut frequency of approximately 600MHz. This low loss filter (typically less

than 0.5dB over 400 to 530MHz) provides excellent immunity to interference from high

frequency signals.

The signal is then further filtered, using a high performance helical resonator doublet

(FL410) which provides exceptional image rejection, before being amplified by approxi-

mately 8dB (Q410). The signal is then passed through a further helical filter doublet

(FL420) before being presented to the mixer via a 2dB attenuator pad.

Each sub-block within the front end has been designed with 50Ω terminations for ease

of testing and fault finding. The overall gain from the antenna socket to the mixer input

is approximately 2dB.

2.3 Mixer

(Refer to the front end circuit diagram (sheet 4) in Section 6.3 and Figure 2.2.)

IC410 is a high level mixer requiring a local oscillator (LO) drive level of +17dBm (nom-

inal). The voltage controlled oscillator (VCO) generates a level of +21dBm (typical) and

this is fed to the mixer via a 5dB attenuator pad. A diplexer terminates the IF port of the

mixer in a good 50Ω, thus preventing unnecessary intermodulation distortion.

2.4 IF Circuitry

(Refer to the IF section circuit diagram (sheet 3) in Section 6.3 and Figure 2.2.)

Losses in the mixer are made up for in a tuned, common gate, post mixer amplifier

(Q310). Several stages of amplification and filtering are employed in the IF circuitry. The

first crystal filter is a 4-pole device (&XF300) which is matched into 50Ω on both its

input and output ports. This stage is followed by a common base amplifier (Q320)

whose output is matched into a 2-pole crystal filter (&XF301). The signal is then ampli-

fied using a high gain MOSFET amplifier (Q350), after which the signal is mixed down

to 455kHz with the second crystal local oscillator (44.5455MHz).

The 455kHz signal is filtered using a 6-pole ceramic filter (&XF302) before being limited

and detected. Q340 provides a buffered 455kHz output for use with the optional RF

level detector (RSSI)

The second IF mixer, limiter and detector is in a 16-pin IC (IC310). Quadrature detection

is employed, using L390, and the recovered audio on pin 9 of IC310 is typically 1Vpp for

60% system deviation.

B2.6 T855 Circuit Operation M8SL2-00-002-812

2.5 Noise Mute (Squelch)

(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respec-

tively) in Section 6.3 and Figure 2.2.)

The noise mute operates on the detected noise outside the audio bandwidth. An opera-

tional amplifier in IC310 is used as an active band pass filter centred on 70kHz to filter

out audio components. The noise spectrum is then further amplified in a variable gain,

two-stage amplifier (Q350 and Q360) with additional filtering. The noise is then recti-

fied (D310) and filtered to produce a DC voltage proportional to the noise amplitude.

The lowest average DC voltage corresponds to a high RF signal strength and the highest

DC voltage corresponds to no signal at the RF input.

The rectified noise voltage is compared with a threshold voltage set up on RV230, the

front panel “Gating Sensitivity” potentiometer. Hysteresis is provided by the feedback

resistor (R267) to prevent the received message from being chopped when the average

noise voltage is close to the threshold. R281 and R280 determine the mute opening and

closing times and, in combination with solder links SL210 and SL220, provide three time

delay options (SL210 is linked as standard. Refer to Section 3.8). The mute control signal

at pin 7 of IC270 is used to disable the speaker and line audio outputs. The speaker out-

put can be separately enabled for test purposes by operating the front panel mute disa-

ble switch, SW201.

2.6 Carrier Mute

(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respec-

tively) in Section 6.3 and Figure 2.2.)

A high level carrier mute facility is also available. The RSSI (refer to Section 2.12) pro-

vides a DC voltage proportional to the signal strength. This voltage is compared with a

preset level, set up on RV235, and may be linked into the mute timing circuit using

PL250. PL250 selects either the noise mute or the carrier mute. From this point both the

noise and carrier mute circuits operate in the same manner, using common circuitry.

M8SL2-00-002-812 T855 Circuit Operation B2.7

2.7 Audio Processor

(Refer to the audio processor circuit diagram (sheet 2) in Section 6.3.)

Figure 2.3 T855 Audio Processor Block Diagram

The recovered audio on pin 9 of IC310 is passed through a compensation network and

processed in a third order elliptic active filter to give the required response. Linking

(PL220 and PL210) is available to give either a flat or de-emphasised audio response,

with de-emphasis giving a –6dB/octave roll off. The output of IC210 is split to provide

separate paths for the speaker and line outputs. The “Audio 1”, Audio 2” and “Speech”

lines allow access to the receiver’s audio path for external signalling purposes (refer to

Section 3.5).

The signals are passed to audio drive amplifiers IC240 and IC260. Under muted condi-

tions the inputs of these amplifiers are shunted to ground via transistors Q230 and Q290

respectively. The audio output of IC240 has a DC component which is removed by C249,

and this then drives a speaker directly. The output of IC260 is fed into a line transformer

to provide a balanced 2-wire or 4-wire, 600Ω output.

The speaker volume is set using the front panel “Monitor Volume” knob (RV205) and

the line level is set using the recessed “Line Level” potentiometer (RV210).

The red front panel “Gate” LED (D250) indicates the status of the mute circuit. When a

signal above the mute threshold is received, the LED is illuminated. The “Monitor”

switch (SW201) on the front panel opens the mute, allowing continuous monitoring of

the audio signal (on = audio unmuted; off = audio muted).

The mute control line is available on pad 234 ("RX GATE OUT") for control of external

circuitry. A high (9V) on pad 234 indicates that the audio is disabled and a low (0V) indi-

cates that a signal above the mute threshold level is being received.

The audio can also be disabled using the “RX-DISABLE” inputs, pads 225 or 228, having

connected the “RX-DISABLE” link between pins 1 and 2 of PL260. An adjustable time

delay (RV220) is provided on these lines. In order to disable the audio, either pad must

be pulled to 0V.

An undedicated relay is provided (RL210) for transmitter keying or other functions and

this can be operated from the mute line by linking PL270.

2.8 Power Supply And Regulators

(Refer to the regulators circuit diagram (sheet 6) in Section 6.3.)

Figure 2.4 T855 Power Supply And Regulators Block Diagram

The T855 is designed to operate off a 10.8 to 16VDC supply (13.8V nominal). A 5.3V reg-

ulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser cir-

cuitry. It is also used as the reference for a DC amplifier (IC640, Q630 and Q620) which

provides a medium current capability 9V supply.

A switching power supply, based on Q670 and Q660, runs off the 9V supply and pro-

vides a low current capability +20V supply. This is used to drive the synthesiser loop fil-

ter (IC740), giving a VCO control voltage of up to 20V.

The 13.8V supply drives both output audio amplifiers without additional regulation. A

separate 5V regulator (IC610) drives the microprocessor and associated digital circuitry.

The output of this regulator is monitored by the Low Voltage Interrupt (LVI) circuit

(IC650).

A crowbar diode is fitted for protection against connection to a power supply of incor-

rect polarity. It also provides transient overvoltage protection.

Note: A fuse must be fitted in the power supply line for the diode to provide effec-

tive protection.

2.9 Microcontroller

(Refer to the microcontroller circuit diagram (sheet 8) in Section 6.3.)

Figure 2.5 T855 Microcontroller Block Diagram

Overall system control of the T855 is accomplished by the use of a member of the 80C51

family of microcontrollers (IC810) which runs from internal ROM and RAM. Four ports

are available for input/output functions.

Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM

(IC820). This serial bus is also used by the microcontroller to program the synthesiser

(IC740).

The main tasks of the microcontroller are as follows:

•program the synthesiser;

•interface with the PGM800Win programming software at 9600 baud via the

serial communication lines on D-range 1 (PL100) and D-range 2;

•monitor channel change inputs from D-range 2;

•generate timing waveforms for CTCSS detection;

•coordinate and implement timing control of the receiver;

•control the front panel “Supply” LED (refer to Section 5.3).

2.10 Synthesised Local Oscillator

(Refer to the synthesiser circuit diagram (sheet 7) in Section 6.3 and the VCO circuit dia-

gram in Part E.)

Figure 2.6 T855 Synthesiser Block Diagram

The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled

oscillator (VCO) to a given reference frequency. The synthesiser receives the divider

information from the control microprocessor via a 3-wire serial bus (clock, data, enable).

When the data has been latched in, the synthesiser processes the incoming signals from

the VCO buffer (fin) and the reference oscillator (fref).

A reference oscillator at 12.8MHz (IC700) is buffered (IC710) and divided down to

6.25kHz or 5kHz within the synthesiser IC (IC740).

A buffered output of the VCO is divided with a prescaler and programmable divider

which is incorporated into the synthesiser chip (IC740). This signal is compared with the

reference signal at the phase detector (also part of the synthesiser chip). The phase

detector outputs drive a balanced charge pump circuit (Q760, Q770, Q775, Q780, Q785)

and active loop filter (IC750, Q790) which produces a DC voltage between 0V and 20V

to tune the VCO. This VCO control line is further filtered to attenuate noise and other

spurious signals. Note that the VCO frequency increases with increasing control volt-

age.

M8SL2-00-002-812 T855 Circuit Operation B2.11

2.11 VCO

(Refer to the VCO circuit diagram in Part E.)

The VCO transistor (Q1) operates in a common emitter, and uses a transmission line res-

onator (TL1). The transmission line is used in a two port configuration with varicaps

positioned at one end. The VCO control voltage from the loop filter (IC750) is applied to

the varicaps (D1 and D2) to facilitate tuning. The VCO output is coupled into a cascode

amplifier stage (Q2 and Q3) which supplies +10dBm (nominal) output. Further amplifi-

cation in Q5 brings the output drive level to +20dBm to drive the mixer.

A low level “sniff” is taken from the input to Q5 to drive the divider buffer to the syn-

thesiser (IC740).

The VCO operates at the actual frequency required by the first mixer, i.e. there are no

multiplier stages.

The VCO frequency spans from 355 to 395MHz, 395 to 435MHz or 435 to 485MHz

according to product type. The VCO is tuned to 45MHz below the desired receive fre-

quency (low side injection) to produce a 45MHz IF signal at the output of the mixer.

B2.12 T855 Circuit Operation M8SL2-00-002-812

2.12 Received Signal Strength Indicator (RSSI)

(Refer to the T800-04-0000 RSSI PCB circuit diagram in Section 6.2 and the IF section cir-

cuit diagram (sheet 3) in Section 6.3.)

The RSSI option PCB plugs directly into the main PCB (support circuitry being fitted as

standard). It is fitted to the T855 whenever receiver signal strength monitoring is

required, e.g. trunking or voting. Its function is to provide a DC voltage proportional to

the signal level at the receiver input. The DC voltage is available at D-range 1 (PL100

pin 5).

The RSSI also provides the capability for high level signal strength muting, which may

be selected on PL250 (refer to Section 3.5). The mute threshold may be set between

–115dBm and –70dBm by RV235.

Figure 2.7 T855 RSSI Block Diagram (T800-04-0000 RSSI PCB)

The variable gain stage (Q1A) is a common emitter amplifier with its emitter grounded

and the AGC control loop voltage applied to its base. Since the AGC loop will maintain

a constant signal level at the collector, the gain of Q1 must be proportional to the incom-

ing 455kHz signal level. The gain of Q1 is linearly proportional to its collector current

which itself is exponentially related to the base-emitter voltage. Thus there is a logarith-

mic relationship between the base-emitter voltage and the gain. The circuit therefore

produces a feedback voltage, and an output voltage, logarithmically related to the RF

input signal.

The AGC loop is followed by a DC amplifier which provides level shifting, temperature

compensation and gain to give a nominal 1V/10dB at the RSSI output. RV320 on the

main PCB is used to set the RSSI voltage to a fixed value at a given RF input signal

strength.

3.1 Introduction

When you receive your T855 receiver it will be run up and working on a particular fre-

quency (the “default channel")1. If you want to switch to a frequency that is within the

5MHz switching range (i.e. ±2.5MHz from the factory programmed frequency), you

should only need to reprogram the receiver with the PGM800Win software (refer to the

PGM800Win programming kit and Section 3.2 below).

However, if you want to switch to a frequency outside the 5MHz switching range, you

will have to reprogram and re-tune the receiver to ensure correct operation. In this case

you should carry out the short tuning procedure described in Section 3.4.

If you have carried out repairs or other major adjustments, you must carry out the full

tuning and adjustment procedure described in this section (except for Section 3.4).

3.2 Channel Programming

You can program up to 128 channel frequencies into the receiver’s EEPROM memory

(IC820) by using the PGM800Win software package and a PC. You can also use

PGM800Win to select the receiver’s current operating frequency (or “default channel").

You can program the receiver via the programming port in the front panel. However,

you can also program the receiver before it is installed in a rack frame as follows:

•by using a T800-01-0010 calibration test unit;

•via D-range 1;

•via D-range 2 (standard T800-03-0000 auxiliary D-range only);

•via SK805 (internal Micromatch connector).

If you do not use the T800-01-0010, you will have to connect the PC to the receiver via a

module programming interface (such as the T800-01-0004).

For a full description of the channel programming procedure, refer to the PGM800Win

programming software user’s manual.

Note: When an auxiliary D-range kit (D-range 2 – T800-03-0000) is fitted, you can

also select a channel with an external switch, such as the DIP switch on a

backplane PCB. Consult your nearest Tait Dealer or Customer Service

Organisation for further details.

1. Use the “Read Module” function in PGM800Win to find out what the default channel

is.

3.4 Short Tuning Procedure

Use this procedure only if you want to reprogram the receiver to a frequency outside the

5MHz switching range and do not intend to carry out any other major adjustments or

repairs.

3.4.1 Introduction

Reprogram the operating frequency as described in the PGM800Win program-

ming kit (refer to Section 3.2).

Remove the top cover.

Set up the test equipment as described in Section 3.3.

Set the links in the audio processor section as required (refer to Section 3.5).

3.4.2 Synthesiser Alignment

•Connect a high impedance voltmeter to the long lead of L1 in the VCO (this meas-

ures the synthesiser loop voltage).

•Single Channel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V.

Multichannel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V on the middle channel.

If there is no middle channel, tune C6 so that the channels

are symmetrically placed around a loop voltage of 10V.

All channels should lie within the upper and lower limits

of 16V and 3V respectively.

Do not attempt to program channels with a greater fre-

quency separation than the specified switching range of

5MHz.

3.4.3 Front End Alignment

Note 1: In this and following sections deviation settings are given first for wide

bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )

and narrow bandwidth sets [ ].

Note 2: For multichannel operation align the receiver on a frequency in the middle

of the required band.

Set RV230 (front panel gating sensitivity) fully clockwise.

Inject a strong on-channel RF signal with ±3kHz deviation (±2.4kHz) [±1.5kHz] at

B3.6 T855 Initial Tuning and Adjustment M8SL2-00-002-812

1kHz into the antenna socket and adjust the helical resonators #FL410 and #FL420

to give best sinad.

Continually decrease the RF level to maintain 12dB sinad.

Readjust FL410 and FL420 to give best sinad.

With PL210 and PL220 connected for de-emphasised audio response, the receiver

sensitivity should be better than –117dBm, assuming that the audio levels are not

being overdriven (refer to Section 3.4.5).

3.4.4 Mute Adjustment

3.4.4.1 Noise Mute

Connect pins 1 and 2 of PL250 to enable the noise mute.

Set the RF level to –105dBm with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz.

Set RV230 (front panel gating sensitivity) fully anticlockwise.

Adjust RV310 (noise mute gain) fully clockwise to close the mute (if necessary

turn off the RF signal and then turn it on again).

Rotate RV310 anticlockwise until the mute just opens.

Reset the signal generator for the required opening sinad and adjust RV230 clock-

wise until the mute just opens.

3.4.4.2 Carrier Level Mute

Connect pins 2 and 3 of PL250 to enable the carrier mute and disable the noise

mute.

Apply an on-channel signal from the RF generator at the required mute opening

level with ±3kHz deviation (±2.4kHz) [±1.5kHz] at ±1kHz.

Adjust RV235 (carrier mute) anticlockwise to close the mute (if necessary, momen-

tarily turn off the RF), then slowly adjust it clockwise until the mute just opens.

The mute should now open at this preset level.

3.4.5 Line Amplifier Output

Apply an on-channel signal from the RF generator at a level of –70dBm with

±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz.

Adjust RV210 (front panel line level) to set the line level to the required output

level.

M8SL2-00-002-812 T855 Initial Tuning and Adjustment B3.7

3.4.6 CTCSS

3.4.6.1 Decoder Operation

Program a CTCSS tone on the default channel using PGM800Win.

Set the RF signal generator output to –70dBm.

Modulate the generator with both:

•a 1kHz tone at ±3kHz deviation (±2.4kHz) [±1.5kHz]

•and a CTCSS tone at the programmed frequency at ±500Hz deviation (±400Hz)

[±300Hz].

Check that the receiver gate opens and the front panel “Gate” LED is on.

3.4.6.2 Opening Sinad

Adjust RV230 (front panel gating sensitivity) fully clockwise.

Reduce the RF signal level to –110dBm.

Observe the sinad meter and reduce the RF level until the receiver mute closes.

Slowly increase the signal level until the receiver mute just opens and stays open.

With PL240 pins 1 and 2 linked (G–H; high pass filter bypassed), check that the

sinad is less than 6dB.

Reset the signal generator for the required opening sinad, adjust RV230 fully anti-

clockwise, then clockwise until the mute just opens.

3.4.6.3 High Pass Filter

Set the audio processor links as follows:

Reset the RF signal generator output to –70dBm and note the line level (measure-

ment A).

Reduce the 1kHz generator to zero output and measure the line level again (meas-

urement B).

Check that measurement B is at least 30dB below measurement A.

3.5.2 Audio Processor Linking Details For CTCSS

You must connect the audio processor links correctly according to the CTCSS option

used, as shown in the table below.

The conditions stated in the above table are defined as follows:

•standard, no CTCSS –no CTCSS or other sub-audio signalling used

–audio bandwidth 300Hz to 3kHz

–hum and noise –55dB

•received CTCSS tone –tone and speech transmitted down 600Ω line

+ speech to line output –audio bandwidth 10Hz to 3kHz

–hum and noise –45dB

•high pass filtered speech –400Hz to 3kHz

+ internal CTCSS detection –hum and noise –30dB with 250.3Hz tone present

•external CTCSS detection –decoding performed through the receiver (but

externally)

–speech injected back into receiver via “AUDIO-2"

and sent down 600Ω line

Note 1: AUDIO-2 is available on D-range 1 (PL100) pin 7 via the link resistor R160.

Although PL100 pin 7 is already assigned to SERIAL-COM, this can be disa-

bled by removing R808.

Note 2: External CTCSS units can connect in series with the audio chain via

AUDIO-1 and AUDIO-2.

3.6 Synthesiser Alignment

•Ensure that the receiver has been programmed with the required frequencies

using the PGM800Win software.

•Connect a high impedance voltmeter to the long lead of L1 in the VCO (this meas-

ures the synthesiser loop voltage).

•Single Channel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V.

Multichannel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V on the middle channel.

If there is no middle channel, tune C6 so that the channels

are symmetrically placed around a loop voltage of 10V.

All channels should lie within the upper and lower limits

of 16V and 3V respectively.

Do not attempt to programme channels with a greater fre-

quency separation than the specified switching range of

5MHz.

•The TCXO =(IC700) output frequency should be trimmed when the IF is tuned.

Refer to Section 3.7.

3.7 Alignment Of Receiver Front End And IF

Note: In this and following sections deviation settings are given first for wide

bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )

and narrow bandwidth sets [ ].

Align the synthesiser as instructed in Section 3.6. For multichannel operation align

the receiver on a frequency in the middle of the required band.

Set RV230 (front panel gating sensitivity) fully clockwise.

Inject a strong on-channel RF signal with ±3kHz deviation (±2.4kHz) [±1.5kHz] at

1kHz into the antenna socket and adjust the helicals (#FL410 and #FL420) to give

the best sinad.

Continually decrease the RF level to maintain 12dB sinad.

Roughly tune IF coils L310, L320, L330, L340, L350, L360, L370, L380, L385 and

L390 for best sinad.

While maintaining a low level unmodulated RF input to the receiver, loosely cou-

ple into the first IF an additional high level signal at 45MHz, you will hear a beat

note.

Trim the synthesiser TCXO (=IC710) for zero beat.

M8SL2-00-002-812 T855 Initial Tuning and Adjustment B3.11

While maintaining the low level RF input to the receiver, loosely couple into the

second IF an additional high level signal at 455kHz, you will hear a beat note.

Tune L385 for zero beat.

Note: If a second oscillator is not available, you can connect a frequency counter to

IC710 pin 8 (i.e. after the TCXO buffer) via an oscilloscope probe to measure

the TCXO frequency directly (12.8MHz). At this point the voltage level is

approximately 4Vpp.

Readjust the front end helicals (#FL410 and #FL420) to give the best sinad.

Change the RF signal level to –75dBm and modulate with ±3kHz deviation

(±2.4kHz) [±1.5kHz] at 1kHz.

Connect an oscilloscope probe to SK320 pin 3 (RSSI 455kHz input) and connect

plugs PL210 and PL220 to give a flat audio response (refer to Section 3.5).

Readjust L310, L320, L330, L340, L350, L360, L370 and L380 to give a maximum

amplitude response on the oscilloscope with minimal amplitude modulation.

Note: If you would like a more accurate method of tuning the IF, refer to the

sweep tuning method described in Section 5.5.5.

Further adjust these coils, along with L390, for minimum audio distortion, ensur-

ing that the 455kHz level (on the oscilloscope) does not fall significantly.

Check that the distortion reading is:

wide bandwidth ≤2%

mid and narrow bandwidth ≤4%.

If required, reconnect plugs PL210 and PL220 to give a de-emphasised audio

response and check that the distortion reading is ≤2% (all bandwidths).

Reduce the RF level until 12dB sinad is reached. The receiver sensitivity should be

better than –117dBm (de-emphasised) or –111dBm (flat), assuming that the audio

levels are not being overdriven (refer to Section 3.11).

Set RV230 (front panel gating sensitivity) fully anticlockwise.

Adjust RV310 (noise mute gain) fully clockwise to close the mute (if necessary

turn off the RF signal and then turn it on again).

Rotate RV310 anticlockwise until the mute just opens.

Reset the signal generator for the required opening sinad and adjust RV230 clock-

wise until the mute just opens.

3.10 Carrier Level Mute

Connect pins 2 and 3 of PL250 to enable the carrier mute and disable the noise

mute.

Apply an on-channel signal from the RF generator at the required mute opening

level with ±3kHz deviation (±2.4kHz) [±1.5kHz] at ±1kHz.

Adjust RV235 (carrier mute) anticlockwise to close the mute (if necessary, momen-

tarily turn off the RF), then slowly adjust it clockwise until the mute just opens.

The mute should now open at this preset level.

With PL240 pins 1 and 2 linked (G – H; high pass filter bypassed), check that the

sinad is less than 6dB.

Reset the signal generator for the required opening sinad, adjust RV230 fully anti-

clockwise, then clockwise until the mute just opens.

3.12.3 High Pass Filter

Set the audio processor links as follows:

Reset the RF signal generator output to –70dBm and note the line level (measure-

ment A).

Reduce the 1kHz generator to zero output and measure the line level again (meas-

urement B).

Check that measurement B is at least 30dB below measurement A.

Reset the front panel controls to the required settings.

4.2 Sensitivity

If CTCSS is enabled, disable the CTCSS tone by either programming the T855 for

“No Tone” on the set channel, or by pulling pin 10 of D-range 2 (CTCSS ENABLE)

low.

Apply an on-channel signal from the RF generator with ±3kHz deviation

(±2.4kHz) [±1.5kHz] at 1kHz.

Adjust the RF level to give 12dB audio sinad.

Check that the sensitivity is –117dBm or better.

4.3 Switching Range

Apply an on-channel signal from the RF generator at various frequencies within

the 5MHz switching range (front end bandwidth), corresponding to pre-pro-

grammed channels.

Measure the sensitivity at each frequency as described in Section 4.2.

Ensure that the sensitivity is –115dBm or better across the whole switching range.

4.4 Audio Distortion

The level of distortion measured at the line output (refer to Figure 1.3 in Part G) gives an

indication of the accuracy of the IF alignment.

Apply an accurate on-channel signal from the RF generator at a level of –70dBm

with ±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz.

Adjust RV210 (front panel line level) to give +10dBm into 600Ω.

Check that the distortion is approximately 1% THD.

Note: For a flat response, the distortion should always be better than 2% for wide

bandwidth sets or 4% for mid and narrow bandwidth sets.

Adjust RV205 (front panel monitor volume) to give 2Vrms into a 4Ω resistive load.

Check that the distortion at the monitor output is better than 2% THD.

Reset the controls before proceeding to the next set of tests.

4.5 Ultimate Signal-To-Noise Ratio

(±2.4kHz) [±1.5kHz] at 1kHz.

Select de-emphasis on the links provided in the audio processor (refer to Section

3.5), and link pins 2 and 3 of PL240 to include the 300Hz filter.

Adjust RV210 (front panel line level) to provide +10dBm output.

Switch off the modulation, checking that the residual noise is lower than –45dBm

(–43dBm) [–39dBm] at the line output (this corresponds to S/N of 55dB (53dB)

[49dB] and is in accordance with EIA measurement conditions).

Note: You can make the measurement without the 300Hz high pass filter, but the

result will be 10dB worse.

4.7 Noise Mute (If Linked In)

Rotate RV230 (front panel gating sensitivity) fully anticlockwise.

Apply an on-channel signal from the RF generator at a level of –110dBm with

±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz.

Increase the RF level in 1dB steps, checking that the mute opens for an RF input

level of approximately –105dBm.

Turn the RF off and check that the mute closes.

Rotate RV230 clockwise and check that the mute opens.

Reset RV230 to give the required opening sinad.

Caution: Some RF generators can cause a false opening of the mute because the

generator produces a burst of noise when the attenuation range

changes. To correct the problem you will have to change generators.

4.8 RSSI (If Fitted)

Apply an on-channel signal from the RF generator at a level of –110dBm with

±3kHz deviation (±2.4kHz) [±1.5kHz] at 1kHz.

Using a high impedance DMM, check that the RSSI output voltage on pin 5 of

D-range 1 (PL100) is 2V (nominal).

Vary the RF level in 5dB steps and check that the RSSI output voltage changes at a

rate of approximately 10dB/V over the range of –115dBm to –70dBm (refer to Fig-

ure 4.2 for RSSI voltage vs signal strength).

5 T855 Fault Finding

Caution: This equipment contains CMOS devices which are susceptible to dam-

age from static charges. Refer to Section 1.2 in Part A for more informa-

tion on anti-static procedures when handling these devices.

The following test procedures and fault finding flow charts may be used to help locate a

hardware problem, however they are by no means a complete fault finding procedure.

If you still cannot trace the fault after progressing through them in a logical manner,

contact your nearest Tait Dealer or Customer Service Organisation. If necessary, you can

get additional technical help from Technical Support, Tait Electronics Ltd, Christchurch,

New Zealand (full contact details are on page 2).

Note 1: In this and following sections deviation settings are given first for wide

bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )

and narrow bandwidth sets [ ].

Note 2: Unless otherwise specified, the term “PGM800Win” used in this and follow-

ing sections refers to version 4.02 and later of the software.

Refer to Section 6 where the parts lists, grid reference index and diagrams will provide

detailed information on identifying and locating components and test points on the

main PCB. The parts list and diagrams for the VCO PCB are in Part E.

The following topics are covered in this section.

M8SL2-00-002-812 T855 Fault Finding B5.3

5.1 Visual Checks

Remove the covers from the T855 and inspect the PCB for damaged or broken compo-

nents, paying particular attention to the surface mounted devices (SMDs).

Check for defective solder joints. If repair or replacement of components is considered

necessary, refer to Section 3 of Part A.

5.2 Component Checks

If you suspect a transistor is faulty, you can assess its performance by measuring the for-

ward and reverse resistance of the junctions. Unless the device is completely desol-

dered, first make sure that the transistor is not shunted by some circuit resistance. Use a

good quality EVM (e.g. Fluke 75) for taking the measurements (or a 20kΩ/V or better

multimeter, using only the medium or low resistance ranges).

The collector current drawn by multi-junction transistors is a further guide to their per-

formance.

If an IC is suspect, the most reliable check is to measure the DC operating voltages. Due

to the catastrophic nature of most IC failures, the pin voltages will usually be markedly

different from the recommended values in the presence of a fault. The recommended

values can be obtained from either the circuit diagram or the component data catalogue.

5.3 Front Panel LED Indicator

The green “Supply” LED on the front panel will flash according to the conditions

described in the following table:

Where two or more conditions occur at the same time, the precedence is in the order

shown above (i.e. receiver linked has the highest priority, followed by VCO error, then

internal error).

PGM800Win

B5.4 T855 Fault Finding M8SL2-00-002-812

5.4 DC Checks

5.4.1 Power Rails

Refer to the test points and options diagrams in Section 6 for test point locations, and to

the regulator fault finding chart (Section 5.7.2) for fault diagnosis.

Check the 9V (TP602) and 13.8V (TP601) power supply test points in the regulator

compartment with a DMM.

Check the 20V regulator output at the test point (TP603) in the regulator compart-

ment.

Check the 5V regulator output at the test point (TP604) in the regulator compart-

ment and on IC310 pin 4.

Check the 5V digital regulator output at the junction of C611A (+) and IC610 pin 2

in the regulator compartment.

5.4.2 VCO Locking

Using a DMM, monitor the VCO control voltage on the long lead of L1 on the

VCO PCB.

If the synthesiser is locked and the VCO aligned, the voltage at this point should

be between 3 and 16V.

If the VCO is not locked, refer to the synthesiser fault finding charts (Section 5.7.3).

5.4.3 Mute Operation

The front panel “Gate” LED will show the status of the mute circuitry and will turn on

when a signal is received above the threshold level.

Check that PL250 is linked correctly:

noise mute 1–2

carrier mute 2–3.

Check that the mute gate opens as follows:

noise mute rotate RV230 (front panel gating sensitivity) fully clock-

wise and check that the front panel “Gate” LED turns on;

carrier mute rotate RV235 (carrier mute) fully clockwise and check that

the front panel “Gate” LED turns on.

If the mute fails to operate correctly, refer to the noise mute fault finding chart (Section

5.7.4) or the carrier mute fault finding chart (Section 5.7.5).

M8SL2-00-002-812 T855 Fault Finding B5.5

5.5 RF Checks

5.5.1 VCO Frequency

Check that the VCO is phase locked (refer to Section 5.4.2).

Connect a frequency counter (level +20dBm) to the VCO input to the mixer

(IC410).

Monitor the local oscillator frequency and check that it is 45MHz below the

required receive frequency.

Refer to the synthesiser fault finding charts (Section 5.7.3) for further information.

5.5.2 RF Sensitivity

Ensure that the VCO is on the correct frequency and the receiver correctly aligned.

Check that the 12dB sinad sensitivity into the front end is as follows:

–117dBm (de-emphasised response)

–111dBm (flat response).

If the sensitivity is poor, you can trace the fault by measuring the sensitivity into

successive circuit blocks. Prepare a test cable by connecting a 1nF capacitor to the

end of a length of coax cable as shown in Figure 5.1.

Figure 5.1 RF Test Cable

Note: Before using the test cable, ensure the coax braid is connected to an earth

point on the PCB.

Using the RF test cable, apply a modulated 45MHz signal to the test breaks in the

IF section, or an on-channel RF signal to the front end test breaks.

Check that the sensitivity at each test break is within 2dB of the levels shown on

the circuit diagram.

Poor sensitivity indicates a fault in one of the circuit blocks following the test break.

Note: Poor sensitivity into the mixer can be caused by lack of drive level from the

VCO (the drive level should be >+17dBm).

Refer to the receiver fault finding charts (Section 5.7.6) for further information.

B5.6 T855 Fault Finding M8SL2-00-002-812

5.5.3 Oscillator Stability

5.5.3.1 TCXO

While maintaining a low level unmodulated RF input to the receiver, loosely cou-

ple into the first IF an additional high level signal at 45MHz. You should now hear

a constant low frequency beat note.

Tap the TCXO with a finger and replace it if the beat note permanently changes.

5.5.3.2 Second IF

While maintaining a low level unmodulated RF input to the receiver, loosely cou-

ple into the second IF an additional high level signal at 455kHz. You should now

hear a constant low frequency beat note.

Adjust L385 for “zero beat".

5.5.4 Demodulator Output

Apply an on-channel RF signal modulated by 1kHz with ±3kHz (±2.4kHz)

[±1.5kHz] deviation at an amplitude of –65dBm.

Connect an oscilloscope probe (DC coupled) to TP314 (audio output).

Check that an audio signal of approximately 800mV peak to peak is present.

Optimum tuning of the quad coil (L390) for minimum audio distortion (with a “flat”

audio response) should coincide with maximum audio amplitude and a DC level of

approximately 1.7V.

5.5.5 IF Distortion

If the audio distortion is still high after careful IF alignment (Section 3.7), sweep the IF to

investigate the bandpass response.

Apply an on-channel RF signal modulated at 10Hz (sine wave) with ±12kHz

(±9kHz) [±6kHz] deviation at an amplitude of –80dBm.

Connect the modulating 10Hz audio signal to the “X” input of an oscilloscope and

observe the 455kHz IF input to SK320 pin 3 via a suitable RF probe on the “Y”

input. Alternatively, if you have an RSSI PCB fitted, use an oscilloscope probe for

the “Y” input to monitor the RSSI output voltage at pad P238 (RSSI test point) or

pin 5 of D-range 1 (PL100). This will give a demodulated log response and only

the top half of the wave forms shown in Figure 5.2 and Figure 5.3 will be dis-

played on the oscilloscope screen.

Note: The “X” input should be DC coupled.

M8SL2-00-002-812 T855 Fault Finding B5.7

Check that the swept response has a rounded top and no sharp non-linearities

(refer to Figure 5.2).

Increase the RF level to –50dBm; the trace will now show the shape of the 455kHz

ceramic filter (&XF302).

Check that the response has no sharp non-linearities.

If sharp non-linearities do occur, replace the filter and sweep again to confirm a

satisfactory solution (refer to Figure 5.3).

5.6 PGM800Win Generated Errors

The following errors are those most likely to occur using PGM800Win. Refer to the

PGM800Win software user’s manual for a complete list of error messages.

Channel Switch Set

The (programmed) default channel change was not accepted by the base station because

a channel is selected externally. Try turning the external channel switch off to change the

default channel in PGM800Win.

Synth Out Of Lock

The synthesiser received incorrect data, or the data was corrupted. Enter a frequency

within the VCO switching range, or tune the VCO.

Internal Error

Data could not be read from the base station due to an internal error. Check for shorts or

open circuits on the SDA, SCK, SYNTH and EPOT lines. The SDA, SCK and SYNTH are

normally high.

Write/Read To An Unlinked Module

The link to the module does not exist. Undefined error.

6.1 Introduction

Product Type Identification

You can identify the receiver type by checking the product code printed on a label on the rear of the

chassis (product codes are explained in Section 1 in the front matter of this manual, and Figure 1.1

in Part A shows typical labels). You can further verify the product type by checking the placement

of an SMD resistor in the table that is screen printed onto the top side of the PCB, similar to the

example drawn below. In this example, the resistor indicates that the product was built as a

T855-10-XXXX.

Note: The only function of this resistor is to indicate the product type. It has no effect on the

circuitry or operation of the receiver.

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note: It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The miscellaneous and mechanical section lists the variant and common parts in IPN order.

Variant Components

A variant component is one that has the same circuit reference but different value or specification in

different product types. Where two products share the same PCB, the term “variant” is also used to

describe components unplaced in one product. Variant components have a character prefix, such as

“&”, “=” or “#”, before the circuit reference (e.g. &R100).

The table below explains the variant prefixes used in T800 SL2 products:

If the variant prefix is. . . the component will. . .

& change according to channel spacing

= change according to frequency stability

# change according to frequency range

% change or be placed/unplaced for special applications

*be unplaced in one product

Grid Reference Index

This section contains a component grid reference index to help you find components and labelled

pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alpha-

numeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams

Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric

border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers

for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is

spread over two or more sheets.

When a line representing part of the circuitry is discontinued, a reference will be given at the end of

the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to

the sheet number and the last two characters refer to the location on that sheet of the continuation of

the circuit (e.g. 1R3).

This sheet shows how the T855 circuitry is divided into separate sections which are

contained within separate cavities in the chassis. It is laid out to show the approximate

location of each section of circuitry on the PCB. The circuitry for each section is shown

on separate numbered sheets, and all components on the PCB are numbered to match

the sheet on which they appear. For example, all audio components appear on sheet 2

and are numbered between 200 and 299, all IF section components are on sheet 3 and

are numbered between 300 and 399, and so on.

M8SL2-00-002-812 T854 General Information C1.5

1.1 Introduction

The T854 is a synthesised, microprocessor controlled FM base station transmitter

designed for single or multichannel operation in the 400 to 520MHz frequency range1

with a standard power output of 25W. The RF section of the transmitter comprises a fre-

quency synthesiser which provides 100mW of frequency modulated RF drive to a two

stage, wide band driver stage followed by a 25W power amplifier. A thermal shutdown

feature is provided in the T854 in case operating temperatures exceed acceptable levels.

The T854 is rated for a continuous output power of 25W at +60°C. This is achieved via a

high capacity heatsink, electric fan and shroud. The fan forces air across the heatsink to

dissipate the heat. The heatsink replaces one of the usual T800 covers.

A wide selection of audio characteristics may be obtained from the audio processor.

Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be

bypassed or linked to one or both audio inputs, and then back into the remaining audio

circuitry in almost any combination. All audio processor options are link selectable.

The synthesiser frequency is programmed via the serial communications port. Eight

channel select lines are accessible via an optional D-range connector (D-range 2 –

T800-03-0000) at the rear of the set.

All components except those of the VCO are mounted on a single PCB. This is secured

to a die-cast chassis which is divided into compartments to individually shield each sec-

tion of circuitry. Access to the PCB is primarily through the top cover of the radio, as all

components are mounted on the top side of the PCB. There is provision within the chas-

sis to mount small option PCBs.

The front panel controls include line sensitivity, microphone socket and carrier switch.

This switch turns on the carrier (unmodulated) as an aid to servicing.

2.2 Microcontroller

Refer to the microcontroller circuit diagram (Sheet 8 – T854 Microcontroller) in Section

6.2

Figure 2.2 T854 Microcontroller Block Diagram

Overall system control of the T854 is accomplished by the use of a member of the 80C51

family of microcontrollers (IC810). It runs from internal ROM and RAM, thus leaving all

four ports free for input/output functions.

Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM

(IC820). This serial bus is also used by the microcontroller to program the synthesiser

(IC740) and deviation control EPOTS (IC220).

The main tasks of the microcontroller are as follows:

•program the synthesiser and EPOT;

•interface with the PGM800Win programming software at 9600 baud via the

serial communication lines on D-range 1 (PL100) and D-range 2;

•monitor channel change inputs from D-range 2;

•generate timing waveforms for CTCSS encoding;

•coordinate and implement timing control of the transmitter.

•control the front panel “Supply” LED (refer to Section 5.3).

2.3 Synthesised Local Oscillator

Refer to the synthesiser circuit diagram (Sheet 7 – T854 Synthesiser) in Section 6.2 and

the VCO circuit diagram in Part E.

Figure 2.3 T854 Synthesiser Block Diagram

The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled

oscillator (VCO) to a given reference frequency. The synthesiser receives the divider

information from the control microprocessor via a 3 wire serial bus (clock, data, enable).

When the data has been latched in, the synthesiser processes the incoming signals from

the VCO buffer (fin) and the phase modulator (fref).

A reference oscillator at 12.8MHz (=IC700) is buffered (IC710 pins 3 and 4) and divided

down to 200kHz (IC730). This 200kHz square wave is then summed with the modulat-

ing audio and passed to an integrator (IC720 pins 9 and 8, Q710, Q720). This produces a

ramping waveform which is centred around a DC level determined by the incoming

audio. IC720 pins 5 and 6 perform as a comparator, ultimately producing a phase-mod-

ulated 200kHz square wave. This is followed by another phase shifting stage (IC720

pins 3 and 4, Q730, Q740), before being divided down to 6.25kHz or 5kHz within the

synthesiser IC (IC740).

A buffered output of the VCO (Q795) is divided with a prescaler and programmable

divider which is incorporated into the synthesiser chip (IC740). This signal is compared

with the phase modulated reference signal at the phase detector (also part of the synthe-

siser chip). The phase detector outputs drive a balanced charge pump circuit (Q760,

Q770, Q775, Q780, Q785) and active loop filter (IC750 pins 5, 6 and 7, Q790) which pro-

duces a DC voltage between 0V and 20V to tune the VCO. This VCO control line is fur-

ther filtered to attenuate noise and other spurious signals. Note that the VCO frequency

increases with increasing control voltage.

If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. This

signal is filtered and buffered by IC750 pins 1, 2 and 3, producing the Lock-Detect signal

used to shut off the power supply to the drive amplifier. IC750 pin 1 is at 20V when the

synthesiser is out of lock.

C2.6 T854 Circuit Operation M8SL2-00-002-812

2.3.1 Two Point Modulation

Frequency modulation occurs by modulating both the VCO input and the synthesiser

reference input. This process is called two point modulation and ensures a flat modula-

tion response from 67Hz to 3kHz (2.55kHz for narrow bandwidth).

The PLL has a fast response time, allowing a Tx key-up time of <30ms. Because of this

fast response time the PLL sees lower modulation frequencies superimposed on the

VCO as an error and corrects for it, resulting in no modulation on the carrier. At modu-

lation frequencies greater than 300Hz the loop cannot correct fast enough and modula-

tion is seen on the carrier. The response of the loop to VCO modulation is shown by f2 in

Figure 2.4 below.

To achieve low frequency modulation, the reference oscillator is also modulated so that

the phase detector of IC740 detects no frequency error under modulation. Thus, the syn-

thesiser loop will not attempt to correct for modulation and the audio frequency

response of the transmitter remains unaffected. The response of the loop to reference

frequency modulation is shown by f1 in Figure 2.4.

The reference modulation is controlled by a 256-step 10k electronic potentiometer

(EPOT) which is adjustable via PGM800Win. The EPOT is made up of 256 resistive sec-

tions (representing approximately 39Ω each) which can be individually addressed by

the microcontroller. Each section can be switched in or out of circuit to achieve the

required total resistance, thus giving control of the reference modulation.

2.4 VCO

(Refer to the VCO circuit diagram in Part E.)

The VCO transistor (Q1) operates in a common emitter configuration, with an LC tank

circuit coupled between its gate and drain to provide the feedback necessary for oscilla-

tion. The VCO control voltage from the loop filter (IC750) is applied to the varicaps (D1

and D2) to facilitate tuning within an 8MHz band of frequencies. A trimcap (C6) is used

for coarse tuning of the VCO. The output from the oscillator circuit drives a cascode

amplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage of amplifi-

cation, Q5. This is the final amplifier on the VCO PCB, and delivers +20dBm (typically)

to the exciter drive amplifier.

A low level “sniff” is taken from the input to Q5 and used to drive the divider buffer for

the synthesiser (IC740).

The VCO operates at the actual output frequency of the exciter, i.e. there are no multi-

plier stages. It is modulated by superimposing the audio signal onto the control voltage

and by phase modulating the reference signal.

2.4.1 VCO Supply

The VCO is supplied from two switched +9V supplies under the control of the Tx-Reg.

supply.

The VCO and buffer amplifier are supplied from one +9V switched supply by Q540 via

the C multiplier (Q550, C530 on the T854 and C550 on the T857).

The output amplifier is supplied from the other +9V supply by Q520, Q530, and Q510.

A delay circuit holds the VCO on for a short time after the Tx-Reg. supply has been

switched off. This is to allow the RF power circuits (both exciter and PA) to ramp down

in the correct manner before the VCO is switched off.

C2.8 T854 Circuit Operation M8SL2-00-002-812

2.5 Audio Processor

Refer to the audio processor circuit diagram (Sheet 2 – T854 Audio Processor) in Section

6.2.

Figure 2.5 T854 Audio Processor Block Diagram

2.5.1 General

The audio processor comprises several link selectable circuit blocks which may be con-

figured in a variety of combinations to suit individual requirements. The pre-emphasis

network and compressor may be linked individually or cascaded between either or both

audio inputs and the limiter.

Refer to Section 3.5.1 for linking details.

2.5.2 Audio Inputs

Two audio inputs are available: one from a 600Ω balanced (or unbalanced) line, and the

other from a local microphone. The microphone signal is passed first to a pre-amplifier

(Q210) and ultimately to a multiplexer (IC240), but in between may pass through the

compressor (depending on the linking details). The line transformer is also connected to

the multiplexer and is disabled by the microphone PTT switch.

A third input for external CTCSS tones is also provided.

M8SL2-00-002-812 T854 Circuit Operation C2.9

2.5.3 Keying Inputs

There are four ways to key the exciter:

•pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set);

•pushing the “Carrier” button on the front panel – this will inhibit all audio;

•using the PTT button on the local microphone, disabling audio from the line;

•via the opto-key inputs (pins 11 and 12 on D-range 1 [PL100]) when electrical

isolation is required. This features a constant current sink (Q270) to ensure reli-

able activation of the opto-coupler (IC250) at low keying voltages.

2.5.4 Compressor (Automatic Level Control (ALC))

The input signal is fed via a current controlled attenuator (Q230, Q220) to a high gain

stage (IC230) from which the output signal is taken. This signal is passed to a compara-

tor (IC230) which toggles whenever the audio signal exceeds a DC threshold deter-

mined by RV220. Thus, the comparator produces a square wave whose mark-space ratio

is determined by the amplitude of the audio signal. This square wave pumps up the res-

ervoir capacitor (C233) which controls the attenuator (Q230, Q220), thus completing the

feedback loop.

The compression level is set by adjustment of the comparator threshold (RV220).

Note: Although the high dynamic range of the compressor allows the use of very

low audio signal levels, such conditions will be accompanied by a degrada-

tion of the signal-to-noise ratio. Very low audio input levels should therefore

be avoided where possible.

2.5.5 Outputs To Modulators

The output signal from the limiter (IC210, IC230) is summed with a CTCSS tone at a

summing amplifier (IC260). The signal is then low pass filtered (IC260) and split to sup-

ply the two modulators.

Since the VCO modulator is a true frequency modulator, its audio is simply buffered

(IC260). The reference modulator, however, is a phase modulator and its audio must

first be integrated (IC210).

It is vital that the audio levels to the modulators are accurately set, relative to each

other. Hence the inclusion of level adjustment in the reference modulator path. Once

set, adjustments to absolute deviation may be made only by IC220, a 256-step 10k elec-

tronic potentiometer (EPOT), which is controlled via PGM800Win. The EPOT is made

up of 256 resistive sections (representing approximately 39Ω each) which can be indi-

vidually addressed by the microcontroller. Each section can be switched in or out of cir-

cuit to achieve the required total resistance, thus adjusting the absolute deviation level.

C2.10 T854 Circuit Operation M8SL2-00-002-812

2.6 Power Supply and Regulator Circuits

Refer to the regulators circuit diagram (Sheet 6 – T854 Regulators) in Section 6.2.

Figure 2.6 T854 Power Supply and Regulators Block Diagram

The T854 is designed to operate from a 10.8 to 16VDC supply (13.8V nominal). A 5.3V

regulator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser cir-

cuitry. It is also used as the reference for a DC amplifier (IC640, Q630, Q620) which

provides a medium current capability 9V supply. The T854 has a regulator (IC370)

which produces 9V for use in the exciter and audio circuits.

A switching power supply (Q660, Q670) runs from the 9V supply and provides a low

current capability +20V supply. This is used to drive the synthesiser loop filter (IC750),

giving a VCO control voltage range of up to 20V.

Ultimate control of the transmitter is via the Tx-Reg. supply, switched from 9V by Q610.

This is enabled via the Tx-Enable signal from the audio processor, and microprocessor.

A crowbar diode is fitted for protection against connection to a power supply of incor-

rect polarity. It also provides transient overvoltage protection.

Note: A fuse must be fitted in the power supply line for the diode to provide effec-

tive protection.

The transmit tail timer, transmit timeout timer and transmit lockout timer can all be set

from PGM800Win. The fields for setting these are found on the system information

page. These three timers operate as follows (refer also to Figure 2.7):

2.8 T854 Drive Amplifier, Fan Control and PA

Refer to Figure 2.1 and the exciter and PA circuit diagrams (sheets 3 and 4) in Section

6.2.

The output power of the PA is maintained at a constant level via a power control loop

applied to the two-stage, wide band exciter amplifier (Q337, Q336). The forward and

reverse RF power levels are sensed via a dual directional coupler and detector diodes

(D440, D420 in the PA cavity). The detected DC signals are buffered (IC330 pins 3 and 5)

and then summed with the ‘power control’ level and fed to the control integrator (IC350

pin 6).

Note: Forward and reflected power signals are summed so that, under high

VSWR, the power control will turn the output RF level down.

To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. and

Lock-Detect signals are gated to inhibit the PA control circuit and to switch off the RF

signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator

(D340, D380, D360).

Cyclic keying control is provided by additional circuitry consisting of several time

delay, ramp and gate stages:

•Q330, IC350 power ramping

•Q326, Q325, Q341 Tx-Reg. and Lock-Detect gate

•Q335, Q340, Q345 delay and PIN switch drive.

This is to allow the RF power circuits (both exciter and PA) to ramp up and down in a

controlled manner so that minimal adjacent channel interference is generated during

the transition.

The output of the wide band amplifier is approximately 1W (+30dBm) for an input of

100mW (+20dBm) from the VCO, when the power control is set to maximum.

A temperature sensor (R481) in the PA cavity presents a voltage to the comparators of

IC340 pin 2 and IC350 pin 2. The fan is switched on and off by the comparator of IC340

and the power fold-back is enabled by the comparator of IC350. Power fold-back

reduces the output power to a preset level that protects the PA semiconductors from

excessive temperatures. Under normal operating conditions, the fan will be activated

before power fold-back can occur and it will prevent the temperature from reaching

damaging levels. The voltage divider ratio of R311 and R312 sets the the temperature at

which the fan is switched on and off. R306 and R340 set the temperature at which power

is reduced. Depending on ambient temperature and ventilation, it may take several

minutes of continuous operation for the fan to be activated.

#R517, #R518 and #R519 form an attenuator to provide good VCO/exciter isolation as

well as the correct exciter drive level.

The attenuator (#R395, #R396 and #R397) aids in producing the correct exciter drive

level to the PA over the three frequency ranges.

M8SL2-00-002-812 T854 Circuit Operation C2.13

The RF output from the exciter is fed to the driver stage (Q410) and then to the final

(Q420). DC is fed to the final via a low pass filter with special low frequency decoupling.

3.1 Introduction

When you receive your T854 transmitter it will be run up and working on a particular

frequency (the “default channel")1. If you want to switch to a frequency that is within

the 8MHz switching range (i.e. ±4MHz from the factory programmed frequency), you

should only need to reprogram the transmitter with the PGM800Win software (refer to

the PGM800Win programming kit and Section 3.2 below).

However, if you want to switch to a frequency outside the 8MHz switching range, you

will have to reprogram and re-tune the transmitter to ensure correct operation. In this

case you should carry out the short tuning procedure described in Section 3.4.

If you have carried out repairs or other major adjustments, you must carry out the full

tuning and adjustment procedure described in this section (except for Section 3.4).

3.2 Channel Programming

You can program up to 128 channel frequencies into the transmitter’s EEPROM memory

(IC820) by using the PGM800Win software package and a PC. You can also use

PGM800Win to select the transmitter’s current operating frequency (or “default chan-

nel").

If the transmitter is installed in a rack frame, you can program it via the programming

port in the speaker panel. However, you can also program the transmitter before it is

installed in a rack frame as follows:

•by using a T800-01-0010 calibration test unit;

•via D-range 1;

•via D-range 2 (standard T800-03-0000 auxiliary D-range only);

•via SK805 (internal Micromatch connector).

If you do not use the T800-01-0010, you will have to connect the PC to the transmitter

via a module programming interface (such as the T800-01-0004).

For a full description of the channel programming procedure, refer to the PGM800Win

programming software user’s manual.

Note: When an auxiliary D-range kit (D-range 2 – T800-03-0000) is fitted, you can

also select a channel with an external switch, such as the DIP switch on a

backplane PCB. Refer to your nearest Tait Dealer or Customer Service

Organisation for further details.

1. Use the “Read Module” function in PGM800Win to find out what the default channel

is.

3.4 Short Tuning Procedure

Use this procedure only if you want to reprogram the T854 to a frequency outside the

8MHz switching range and do not intend to carry out any other major adjustments or

repairs.

3.4.1 Introduction

Reprogram the operating frequency as described in the PGM800Win program-

ming kit (refer to Section 3.2).

Remove the top cover.

Set up the test equipment as described in Section 3.3.

Set the links in the audio processor section as required (refer to Section 3.5).

3.4.2 Synthesiser Alignment

•Connect a high impedance voltmeter to the long lead of L1 in the VCO (this meas-

ures the synthesiser loop voltage).

•Key the transmitter by earthing the Tx-Key line.

•Single Channel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V.

Multichannel Tune VCO trimmer C6 for a synthesiser loop voltage of

10V on the middle channel.

If there is no middle channel, tune C6 so that the channels

are symmetrically placed around a loop voltage of 10V.

All channels should lie within the upper and lower limits

of 16V and 3V respectively.

Do not attempt to program channels with a greater fre-

quency separation than the specified switching range of

8MHz.

3.4.3 Output Power Adjustment

Connect an RF power meter with suitable attenuation to the output socket and

key the transmitter.

Turn RV310 (power control) fully clockwise.

Tune #CV475 (output power trim) for maximum output power and check that this

is >30W.

Adjust RV310 for the required output power (between 5 and 25W).

Readjust #CV475 to reduce the supply current by up to 0.5A.

C3.6 T854 Initial Tuning and Adjustment M8SL2-00-002-812

3.4.4 Two Point Modulation Adjustment

Note 1: In this and following sections deviation settings are given first for wide

bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )

and narrow bandwidth sets [ ].

Note 2: The reference modulation and limiter adjustments are controlled by 256-

step electronic potentiometers (EPOTs), which are adjusted via the “Refer-

ence Modulation” and “Deviation” settings in PGM800Win. This allows the

two point modulation and deviation settings to be adjusted for each chan-

nel.

Note 3: To optimise the modulation response across the switching range, repeat

steps 1 to 4 below for each channel that will be used (usually needed only

for data applications). In applications where the modulation response is less

critical (e.g. voice use only), carry out steps 1 to 4 below on the middle chan-

nel and use the “EPOT Fill” option1 in PGM800Win to copy the value to the

other channels.

Note 4: If you are using an RF test set, turn the low pass filter off and set the high

pass filter to 15kHz before beginning this procedure.

1. Inject an audio signal of 300Hz 1.5Vrms (+5dBm) into the CTCSS input (D-range 1

(PL100) pin 8).

Key the transmitter by earthing the Tx-Key line.

2. Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz]

deviation at 300Hz.

3. Change the input frequency to 100Hz and, using PGM800Win, adjust the value of

the “Reference Modulation” EPOT setting for the current channel to obtain ±3kHz

(±2.4kHz) [±1.5kHz] deviation (you can use either the mouse or up and down

arrow keys).

4. Change the input frequency back to 300Hz.

Repeat steps 2 and 3 above until the deviations achieved at the two input frequen-

cies are within 0.2dB of each other. You will need to do this at least four times.

5. Sweep the audio between 50 and 300Hz for peaks.

Note: A peak between 50 and 300Hz will indicate a fault condition, i.e:

– incorrect set-up

or – modulation circuitry fault.

The specification window is ±1dB relative to 150Hz from 67 to 260Hz.

1. Use the “EDIT FILL” button on the tool bar or go to “Edit”, “Fill”, “Epot Settings” on

the menu bar.

M8SL2-00-002-812 T854 Initial Tuning and Adjustment C3.7

3.4.5 CTCSS Encoder (If Used)

Program a CTCSS tone on the default channel using PGM800Win.

If you are using an RF test set, turn off the 300Hz high pass filter.

Key the T854 with the front panel “Carrier” switch.

Adjust RV805 (CTCSS level adjust) to give ±500Hz (±350Hz) [±250Hz] deviation.

Set the maximum deviation as per Section 3.4.6.

3.4.6 FM Deviation (Limiter) Adjustment

Note: If the T854 will be used over the whole 8MHz switching range, you must set

the deviation for each channel. However, if the module will be used on fre-

quencies that cover only a 1MHz (or less) switching range, you can set the

deviation on the middle channel and use this value for all other channels

with the “EPOT Fill” option in PGM800Win.

Inject 1kHz at –10dBm into the line input (D-range 1 (PL100) pins 1 and 4; pins 2

and 3 shorted; refer to Section 1.5 of Part G).

Adjust RV210 (line sensitivity) fully clockwise and key the transmitter by earthing

the Tx-Key line. Using PGM800Win, adjust the value of the “Deviation” EPOT set-

ting for the current channel to obtain a deviation limit of ±4.7kHz (±3.8kHz)

[±2.3kHz] (you can use either the mouse or up and down arrow keys).

Sweep the audio frequency from 100Hz to 4kHz and ensure that the maximum

deviation does not exceed ±4.7kHz (±3.8kHz) [±2.3kHz]. Readjust “Deviation” if

necessary via PGM800Win.

3.4.7 Line-in Level Adjustment

Remove the CTCSS signal (if used).

Set the injected signal at the line input to the required line level (typically –10 to

–20dBm).

Adjust RV210 (line sensitivity) to provide ±3kHz (±2.4kHz) [±1.5kHz] deviation.

Reapply the CTCSS signal (if required).

M8SL2-00-002-812 T854 Initial Tuning and Adjustment C3.11

3.9 Audio Processor and CTCSS

3.9.1 Two Point Modulation

The T854 utilises two point modulation to obtain a wide audio bandwidth independent

of the synthesiser loop filter response. This is achieved by simultaneously frequency

modulating the VCO and phase modulating the synthesiser reference frequency. The

relative signal levels fed to the two modulators are quite critical and cause interaction

when setting up.

Both modulating signals require readjustment when the exciter is shifted in frequency

greater than the switching range (i.e. ∆F>±4MHz).

Note 1: In this and following sections deviation settings are given first for wide

bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )

and narrow bandwidth sets [ ].

Note 2: The reference modulation and limiter adjustments are controlled by 256-

step electronic potentiometers (EPOTs), which are adjusted via the “Refer-

ence Modulation” and “Deviation” settings in PGM800Win. This allows the

two point modulation and deviation settings to be adjusted for each chan-

nel.

Note 3: To optimise the modulation response across the switching range, repeat

steps 1 to 4 below for each channel that will be used (usually needed only

for data applications). In applications where the modulation response is less

critical (e.g. voice use only), carry out steps 1 to 4 below on the middle chan-

nel and use the “EPOT Fill” option1 in PGM800Win to copy the value to the

other channels.

Note 4: If you are using an RF test set, turn the low pass filter off and set the high

pass filter to 15kHz before beginning this procedure.

3.9.2 Modulator Adjustment

1. Inject an audio signal of 300Hz 1.5Vrms (+5dBm) into the CTCSS input (D-range 1

(PL100) pin 8).

Key the transmitter by earthing the Tx-Key line.

2. Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz]

deviation at 300Hz.

3. Change the input frequency to 100Hz and, using PGM800Win, adjust the value of

the “Reference Modulation” EPOT setting for the current channel to obtain ±3kHz

(±2.4kHz) [±1.5kHz] deviation (you can use either the mouse or up and down

arrow keys).

1. Use the “EDIT FILL” button on the tool bar or go to “Edit”, “Fill”, “Epot Settings” on

the menu bar.

C3.12 T854 Initial Tuning and Adjustment M8SL2-00-002-812

4. Change the input frequency back to 300Hz.

Repeat steps 2 and 3 above until the deviations achieved at the two input frequen-

cies are within 0.2dB of each other. You will need to do this at least four times.

5. Sweep the audio between 50 and 300Hz for peaks.

Note: A peak between 50 and 300Hz will indicate a fault condition, i.e:

– incorrect set-up

or – modulation circuitry fault.

The specification window is ±1dB relative to 150Hz from 67 to 260Hz.

3.9.3 CTCSS Encoder (If Used)

1. Program a CTCSS tone on the default channel using PGM800Win.

2. If you are using an RF test set, turn off the 300Hz high pass filter.

3. Key the T854 with the front panel “Carrier” switch.

4. Adjust RV805 (CTCSS level adjust) to give ±500Hz (±350Hz) [±250Hz] deviation.

5. Set the maximum deviation as per Section 3.9.4.

3.9.4 Limiter Adjustment

Note: If the T854 will be used over the whole 8MHz switching range, you must set

the deviation for each channel. However, if the module will be used on fre-

quencies that cover only a 1MHz (or less) switching range, you can set the

deviation on the middle channel and use this value for all other channels

with the “EPOT Fill” option in PGM800Win.

1. Set the links in the audio processor section as required (refer to Section 3.5).

2. Inject 1kHz at –10dBm into the line input (D-range 1 (PL100) pins 1 and 4; and

pins 2 and 3 shorted; refer to Section 1.5 of Part G).

3. Adjust RV210 (line sensitivity) fully clockwise and key the transmitter by earthing

the Tx-Key line. Using PGM800Win, adjust the value of the “Deviation” EPOT set-

ting for the current channel to obtain a deviation limit of ±4.7kHz (±3.8kHz)

[±2.3kHz] (you can use either the mouse or up and down arrow keys).

4. Sweep the audio frequency from 100Hz to 4kHz and ensure that the maximum

deviation does not exceed ±4.7kHz (±3.8kHz) [±2.3kHz]. Readjust “Deviation” if

necessary via PGM800Win.

M8SL2-00-002-812 T854 Initial Tuning and Adjustment C3.13

3.9.5 Line Level Without Compressor

This section assumes that the compressor is not used. If the compressor is required, refer

to Section 3.9.6.

1. Remove the CTCSS signal (if used).

2. Adjust the line sensitivity as follows:

•set the injected signal at the line input to the required line level (typically –10 to

–20dBm)

•adjust RV210 (line sensitivity) to provide ±3kHz (±2.4kHz) [±1.5kHz] deviation

3. Reapply the CTCSS signal (if required).

3.9.6 Compressor

The compressor may be used on the line input only, the microphone input only, or on

both the line and microphone inputs. If the compressor is used, refer to one of the fol-

lowing sections as appropriate.

3.9.6.1 Compressor On Line Input Only

1. Set RV210 (line sensitivity) fully clockwise and key the transmitter by earthing the

Tx-Key line.

2. Reduce the line level to –50dBm at 1kHz and set RV220 (compression level) fully

clockwise.

3. Check that ±3kHz deviation (±2.4kHz) [±1.5kHz] is still available.

4. Slowly increase the audio input level until the demodulated waveform shows sig-

nificant signs of clipping (approximately ±4.5kHz (±3.6kHz) [±2.3kHz] deviation).

5. Adjust RV220 anticlockwise until the demodulated waveform is just clipping

(approximately ±4kHz (±3.2kHz) [±2kHz] deviation).

6. Increase the input level to –10dBm and check that the test tone is still held just into

clipping. The input line level should be typically –10 to –20dBm.

3.9.6.2 Compressor On Microphone Input Only

1. Key the transmitter by earthing the Tx-Key line and plug a microphone jack into

the front panel socket.

2. Adjust RV220 (compression level) fully clockwise.

3. Acoustically couple the microphone to a tone box (1kHz) and close the PTT

switch.

C3.14 T854 Initial Tuning and Adjustment M8SL2-00-002-812

4. Increase the audio level until the demodulated waveform shows significant signs

of clipping (approximately ±4.5kHz (±3.6kHz) [±2.3kHz] deviation).

5. Adjust RV220 anticlockwise until the demodulated waveform is just clipping

(approximately ±4kHz (±3.2khz) [±2kHz] deviation).

6. Increase the audio level by 10dB and verify that the test tone is held just into clip-

ping.

7. Whistle steadily into the microphone, checking that approximately ±4kHz

(±3.2khz) [±2kHz] deviation is produced. The modulated waveform should be

basically sinusoidal.

8. Speak into the microphone, checking that the modulation peaks reach about

±5kHz (±4kHz) [±2.5kHz] deviation.

9. As the line is to be used without compression, set RV210 (line sensitivity) as

described in Section 3.9.5.

3.9.6.3 Compressor On Both Line and Microphone Inputs

Set up as described in Section 3.9.6.1.

3.10 Power Alarms (if used)

When fitted to the T854 transmitter an alarm board monitors the transmitter output

power and generates a low forward-power and/or high reverse-power alarm as appro-

priate.

This is achieved by monitoring the output voltages of the transmitters forward and

reverse power directional coupler. A comparison between these voltage levels and user

defined reference voltages generates alarm conditions accordingly. The low forward

power output signal is also gated with the Tx-enable input to ensure that no alarm is

generated when the transmitter is not transmitting. The high reverse power alarm out-

put is not gated. The alarm signal is output on the T854 Aux D-range.

There are two alarms boards currently available, the recently introduced and improved

T800-10-0520 Tx-Alarm/Channel Select board and the older T1500-52-0000, which it

replaces. The alarm outputs of both the these boards are compatible with the

T1511-20-0000 CCM module and the T803-02 Tone Remote and Alarm interface.

pinched. Replace both covers.

3.10.1.2 T1500-52-0000 Testing/Alignment

Equipment required

•50Ω power meter

•3 or 6dB attenuator as needed.

Forward alarm

1. Connect the power meter to the transmitter output.

2. Key up the transmitter and set the output power to the desired low forward

power alarm threshold point.

3. Adjust the “Fwd-alarm adjust” preset until the forward alarm LED just comes

ON.

4. Reset the output power to the operational output level. Check the alarm output is

now OFF.

Reverse alarm

1. Connect the power meter to the transmitter output.

2. Key up the transmitter and set the output power level to the operational output

level.

3. Replace the power meter with the appropriate valued open ended attenuator. This

should generate the desired return loss/reflected power for the desired high

reverse power alarm threshold point.

5. Turn the transmitter OFF.

3.10.2 T800-10-0520 Tx-Alarm/Channel-Select Kit

When fitted to a T854 transmitter, the T800-10-0520 Tx-Alarm/Channel-Select plug-in

board provides the following features:

•The plug-in board monitors the transmitter’s output power, and generates a

low forward-power and/or high reverse-power alarm as appropriate.

•The plug-in board also includes channel select switches that enables the user to

manually set the operational channel of the T854.

The plug-in board provides the same alarm outputs as the T1500-52-0000:

•Forward Power Alarm: Aux D-range pin 13

•Reverse Power Alarm: Aux D-range pin 14

Note: AUX-OUT-0 is disabled when the plug-in board is installed.

The Tx-Alarm function is achieved by comparing the output voltages of the transmit-

ter’s directional coupler to user-defined reference levels.

The low forward-power alarm output is gated with the Tx-Enable input, to ensure that

no alarm is generated when the transmitter is not transmitting. The high reverse-power

alarm is not gated.

Note: The plug-in board does not require additional wiring. It can be set up on the

bench. This is possible because the Tx-Enable line is accessed from inside the

T854, rather than from the backplane PCB (as on the T1500-52-0000).

Parts Supplied

T800-10-0520 Tx-Alarm/Channel-Select Kit should contain the following:

•T800-10-0520 plug-in board

Caution: This equipment contains CMOS devices which are susceptible to dam-

age from static charges. Refer to Section 1.2 in Part A for more informa-

tion on anti-static procedures when handling these devices.

The following test procedures and fault finding flow charts may be used to help locate a

hardware problem, however they are by no means a complete fault finding procedure.

If you still cannot trace the fault after progressing through them in a logical manner,

contact your nearest Tait Dealer or Customer Service Organisation. If necessary, you can

get additional technical help from Technical Support, Tait Electronics Ltd, Christchurch,

New Zealand (full contact details are on page 2).

Note 1: In this and following sections deviation settings are given first for wide

5.1 Visual Checks

Remove the top cover from the T854 and inspect the PCB for damaged or broken com-

ponents, paying particular attention to the surface mounted devices (SMDs).

Check for defective solder joints. If repair or replacement is considered necessary, refer

to Section 3 of Part A.

5.2 Component Checks

If you suspect a transistor is faulty, you can assess its performance by measuring the for-

ward and reverse resistance of the junctions. Unless the device is completely desol-

dered, first make sure that the transistor is not shunted by some circuit resistance. Use a

good quality EVM (e.g. Fluke 75) for taking the measurements (or a 20kΩ/V or better

multimeter, using only the medium or low resistance ranges).

The collector current drawn by multi-junction transistors is a further guide to their per-

formance.

If an IC is suspect, the most reliable check is to measure the DC operating voltages. Due

to the catastrophic nature of most IC failures, the pin voltages will usually be markedly

different from the recommended values in the presence of a fault. The recommended

values can be obtained from either the circuit diagram or the component data catalogue.

5.3 Front Panel LED Indicator

The green “Supply” LED on the T854 front panel will flash according to the conditions

described in the following table:

Where two or more conditions occur at the same time, the precedence is in the order

shown above (i.e. T854 linked has the highest priority, followed by internal error).

5.4 DC Checks

5.4.1 Power Rails

Refer to the test points and options diagrams in Section 6 for test point locations, and to

the regulator fault finding chart (Section 5.7.2) for fault diagnosis.

Check the 13.8V (TP601) and 9V (TP602) supplies at their test points in the regula-

tor compartment with a DMM.

Check the 5V (TP604) and 20V (TP603) rails at their respective test points in the

regulator compartment.

Check that Tx-Reg. (TP305 in the exciter compartment) comes up to 8.8V when the

exciter is keyed.

Check the +5V digital regulator output (TP607 in the regulator compartment).

Check the 9V supply (IC370 pin 1) with a DMM.

Check for short circuits.

5.4.2 VCO Locking

Key the exciter.

Using a DMM, monitor the VCO control voltage between between L1 and PL14

pin1 on the VCO PCB.

If the synthesiser is locked and the VCO aligned, the voltage at this point should

be between 3 and 16V.

If the VCO is not locked, refer to the synthesiser fault finding chart (Section 5.7.3).

M8SL2-00-002-812 T854 Fault Finding C5.5

5.5 RF Checks

In-circuit RF levels may be measured with an RF probe on which the earth lead has been

shortened to a minimum (i.e. 13mm). Refer to the circuit diagrams for typical levels.

Figure 5.1 shows a suitable RF probe circuit.

Figure 5.1 RF Diode Probe Circuit

5.5.1 T854 Drive Power

Refer to the drive amplifier fault finding chart (Section 5.7.4).

Ensure that the VCO locks (refer to Section 5.4.2).

Connect the drive output to a power meter and key the transmitter.

Check that the exciter output power (SK310) is >1.5W.

Note: If the synthesiser is out of lock, the lock detector (synthesiser IC740 and

comparator IC750) will prevent the RF signal from reaching the PA by

switching the supply to the exciter amplifier (Q336, Q337).

5.5.2 T854 PA Output Power

Reconnect the drive output to the PA input.

Connect the PA to a power meter and key the transmitter.

Check that the output power is >30W with RV310 (power control) adjusted fully

clockwise.

5.5.3 Audio And Modulation

Refer to the audio processor fault finding chart (Section 5.7.6).

Set up the audio processor as described in Section 3.9.

Check that the demodulated RF output has the frequency response referred to in

Section 4.5 with at least ±5kHz (±4kHz) [±2.5kHz] deviation available at 1kHz

modulating frequency.

If the above result is not achieved, either the dual point modulation is incorrectly

adjusted or a fault condition exists.

5.6 PGM800Win Generated Errors

The following errors are those most likely to occur using PGM800Win. Refer to the

PGM800Win software user’s manual for a complete list of error messages.

Channel Switch Set

The programmed default channel change was not accepted by the base station because a

channel is selected externally. Try turning the external channel switch off to change the

default channel in PGM800Win.

Synth Out Of Lock

The synthesiser received incorrect data, or the data was corrupted. Enter a frequency

within the VCO switching range, or tune the VCO.

Internal Error

Data could not be read from the base station due to an internal error. Check for shorts or

open circuits on the SDA, SCK, SYNTH and EPOT lines. The SDA, SCK and SYNTH are

normally high, and the EPOT is normally low.

Write/Read To An Unlinked Module

The link to the module does not exist. Undefined error.

5.8 To Replace The T854 PA Transistors

(Q410 and Q420)

Caution: Failure to comply with the following procedure can result in failure of

the device due to poor heatsinking, or worse, can endanger the health

of the assembler if the beryllium oxide die carrier is smashed during

assembly.

Caution: As the location of certain components in the PA is critical to perform-

ance, it is important that any components removed or disturbed are

refitted in exactly the same position.

Before attempting to remove a transistor, measure the distance

between the capacitors and transistor body to the nearest 0.5mm (meas-

urement “A” in Figure 5.2) so that the capacitors can be replaced in

exactly the same position. These measurements are shown in Figure

5.2 for the 6LFL package, however the same procedure applies for the

SOE (stud) package.

Caution: Do not apply too much heat or pressure to the PCB pads and tracks as

you may damage them or lift them from the PCB, causing permanent

damage to the transmitter.

Figure 5.2 Typical Transistor/Capacitor Spacing (Not To Scale)

Desolder and remove the components from around the transistor.

Q420 Only: Desolder and remove the two solder tags.

Desolder the transistor tabs by heating with a soldering iron and lifting away

from the PCB with a screwdriver or thin stainless steel spike, then remove the

device.

base collector

measurement A

C5.18 T854 Fault Finding M8SL2-00-002-812

Q410 Only: Unscrew the transistor stud nut and remove the device.

Remove any excess solder from the PCB pads with solder wick.

Trim the tabs of the replacement transistor so that the device sits neatly on the

PCB pads provided.

Lightly tin the underside of the transistor tabs. Remove any excess solder to leave

a thin, even layer on the tabs.

Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) to

the transistor mounting surface. Sufficient compound should be used to ensure an

even film over the entire mounting surface.

Place the transistor on the PCB in the correct orientation and ensure the tabs are

flush to the surface.

Q410 Only: Lightly solder one tab to the PCB, then torque down the retain-

ing nut to the correct torque (0.7Nm/6in.lbf.).

Caution: Do not solder all the tabs before torquing down otherwise the device

may be broken.

Q420 Only: Refit the solder tags.

Solder all transistor tabs to the PCB.

Replace each component in exactly the same position as noted previously.

6.1 Introduction

Product Type Identification

You can identify the transmitter type by checking the product code printed on a label on the rear of

the chassis (product codes are explained in Section 1 of the front matter in this manual, and Figure

1.1 in Part A shows typical labels). You can further verify the product type by checking the place-

ment of an SMD resistor in the table that is screen printed onto the top side of the PCB, similar to the

example drawn below. In this example, the resistor indicates that the product was built as a

T854-10-XXXX.

Note: The only function of this resistor is to indicate the product type. It has no effect on the

circuitry or operation of the transmitter.

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note: It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The miscellaneous and mechanical section lists the variant and common parts in IPN order.

Variant Components

A variant component is one that has the same circuit reference but different value or specification in

different product types. Where two products share the same PCB, the term “variant” is also used to

describe components unplaced in one product. Variant components have a character prefix, such as

“&”, “=” or “#”, before the circuit reference (e.g. &R100).

The table below explains the variant prefixes used in T800 SL2 products:

If the variant prefix is. . . the component will. . .

& change according to channel spacing

= change according to frequency stability

# change according to frequency range

Grid Reference Index

This section contains a component grid reference index to help you find components and labelled

pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alpha-

numeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams

Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric

border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers

for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is

spread over two or more sheets.

When a line representing part of the circuitry is discontinued, a reference will be given at the end of

the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to

the sheet number and the last two characters refer to the location on that sheet of the continuation of

the circuit (e.g. 1R3).

1.1 Introduction

The T803-02 is a tone-operated Remote Controller otherwise known as a Tone Remote.

Features include alarm monitoring, voting tone generation and simple high site control.

It interfaces either a 2-wire or 4-wire line circuit to the T800 SL2 Base Station and thus

enables a dispatch console (also known as a desktop controller) to monitor and control

the remote basestation. The T803-02 interfaces with the SL2 receiver and transmitter via

the backplane PCB (X800-56-PCB3) and two small flat cable looms plugged into the D-

ranges on the back. The T803 is configured using the Tait PGM800Win programming

software (V4.02 and later) on a PC.

1.1.1 Tone Remote

The T803 tone remote enables a remotely located user to:

•key the transmitter

•defeat the receiver’s CTCSS mute (to monitor a channel)

•change the set channel (up to 256 channels)

•change between base station and repeater modes (repeater knockdown)

•monitor and cancel alarms

•turn repeater site equipment on or off (highsite control)

•loop back line audio (4-wire line interface only)

This is achieved using three industry-standard tone signalling plans for ease of integra-

tion into existing control systems and choice of vendor for office/control room equip-

ment. These plans are:

•EIA tone remote using a single function tone.

In this system when the control room user presses the transmit key, the line con-

trol equipment sends a 120ms long burst of high level guard tone (HLGT – usually

2175Hz at +10dBM to line). This is followed by a single 40ms function tone at

0dBm to line. The available tone set is 650Hz to 2050Hz in 100Hz steps. This func-

tion tone can change channel, monitor the radio channel (defeat receiver CTCSS)

or a variety of other functions. Following these initial tone bursts a low level

guard tone (LLGT – usually 2175Hz at –20dBm) is sent to line and speech is gated

onto line (at approx 0dBm peak level). This continues until the user releases the

transmit key. This removes speech from the line and low level guard tone ceases.

•EIA enhanced tone remote using two function tones.

This is a variant of the above system where two function tones are sent one after

the other in the period between the high level guard tone and the low level guard

tone. The tone set is also expanded (650Hz to 2050Hz in 100Hz steps) to give 225

possible combinations which can be allocated to various actions. The duration of

both high level guard tone and function tones can be varied.

• Simple Transmitter keying using low level guard tone.

This is used where complex functionality is not required. One application is to key

a link transmitter where the high level guard tone, the function tones, speech and

low level guard tones are transparently carried to an end base station. Note that in

D1.4 General Information M8SL2-00-002-812

this application the notch filters (which ordinarily remove the key tone from the

audio path) must be turned off using PGM800Win so that the keying signal is

propagated to the end transmitter.

1.1.2 Alarm Monitoring and Confirmations

The T803 monitors three T800 sub-rack alarms (transmitter forward and reverse power,

and low battery/power supply), one line alarm (line fail indication) and four external

closure alarms. If alarms are triggered the T803 can be programmed to generate tone

sequences (DTMF, Selcall or function tones) and/or enable auxiliary outputs, to alert

system users of a problem. The tone sequences can be sent to line and/or radio.

Additionally the T803-02 can be programmed to respond to as many as eight different

non-alarm triggers. These can be used as confirmation that an event has occurred. Con-

firmations can be programmed to occur in the event of power-up, channel change and/

or the detection of up to six user defined function tones. In the same way as for alarms,

the T803 can generate tone sequences and/or enable auxiliary outputs as a response to a

confirmation.

1.1.3 Voting Tones

The T803 can also generate voting tones where a 4-wire line interface is used. Voting

systems are used where several base station receivers are tuned to the same radio chan-

nel and located at different sites, sending audio back to a central control where the best

quality audio must be selected or “voted upon”. Tone on Idle or Sliding Voting Tones

can be generated to interface a T800 sub-rack to a wide variety of industry standard

Radio Voting systems.

In Tone on Idle applications, a tone (normally the same frequency as LLGT) is transmit-

ted to line when the T800 receiver is muted. When the tone disappears, control room

equipment can perform signal to noise measurements on incoming audio lines and

select the best for feeding to the control room user.

In Sliding Voting Tone systems, a tone is transmitted to line whose frequency is propor-

tional to the T800 receiver’s RSSI. Control room equipment determines which receiver

has the highest RSSI and thus selects which line carries the highest quality incoming

audio.

1.1.4 Other Features

•Programmable Morse Code Encoder for automatic station identification (CWID)

•User programmable Line levels

•Programmable Transmit and Receive audio path delays

•Programmable (on/off) notch filtering.

no guarantee that the T803 complies with the EMC standards.

2. Only one turn of the 2-wire or 4-wire line is required through the ferrite. However,

two turns are recommended (see Figure 1.3) as this provides extra immunity

while also securing the ferrite in position.

3. Ensure that the 2-wire or 4-wire line does not impede the closing of the ferrite

clamp.

2.1 Circuit Overview

Figure 2.1 High Level Block Diagram

The T803 is connected to a leased line from control room equipment by means of an

RJ45 connector. 600R transformers are used to couple the audio into and out of the T803.

On the secondary of these line matching transformers are analogue transmission

switches which configure the line interface as either 2-wire or 4-wire compatible. Audio

from line is passed through a programmable electronic potentiometer (e-pot) level con-

trol circuit before entering a CODEC where it is digitised. Audio to line is output from

the same line CODEC, via a second programmable e-pot level control circuit.

The line CODEC is connected to a digital signal processor (DSP) which is also connected

to a similar radio CODEC (the CTCSS CODEC is not used in this application). The radio

CODEC receives audio from the T800 receiver and sends audio to the T800 transmitter

to which it is connected via the special backplane PCB. Receiver audio is low frequency

filtered to extend the radio CODEC’s effective frequency range.

The DSP processes the digitised audio streams from the CODECs in accord with instruc-

tions sent to it by the T803’s microcontroller. The DSP can:

•detect high level guard tone, low level guard tone and function tones coming

from line, notch filter line in and receiver audio (used to eliminate low level

guard tone from line out and transmitter audio);

•generate Selcall DTMF/function tone alarms and pip tones to Line-Out and

transmitter audio;

•generate voting tones to Line-Out;

•generate morse code to transmitter audio;

•cross connect line and radio audio paths;

•adjusts the Line-In and Line-Out levels;

In the quiescent state, audio on the Line-In pair is passed through the DSP (IC300) unfil-

tered to the T803 loudspeaker (which is connected to Tx audio – TP203). The audio is

bandpass filtered to detect guard tone. In normal operation (keytone and function tone

operation) the tone detector threshold is set for high level guard tone (HLGT).

If HLGT is detected, the DSP signals this detection to the micro using the

TONE_DETECT line (TP300 is pulled low). The micro instructs the DSP, using the asyn-

chronous serial communications connection (TP306) between them, to switch on the in

line guard tone notch filter, lower the threshold of the guard tone detector (so that it can

detect low level guard tone – LLGT) and turn on the function tone detectors.

Where the T803 is operating in 2-wire mode and receiver audio (RX audio) is being

gated to line, the micro will soft mute the RX audio first). The micro then starts an inter-

nal timer, the duration of which is set by the HLGT and function tone times pro-

grammed by PGM800Win.

If a function tone is detected, the DSP signals the micro using the CALL_UP line (TP301

pulled low). The micro then interrogates the DSP via the serial communications connec-

tion to find out what frequency was detected.

If no tones are detected and the timer expires, the micro resets the DSP to its quiescent

state. If two different frequencies are detected or if only one function tone frequency is

decoded and the timer expires, the micro decodes them/it into an action by reading

data programmed into the EEPROM (IC312) by PGM800Win. The micro then keys on

the transmitter (PTT line) and instructs the DSP to turn off the function tone detectors

and the talk-through gate (if it was on). If the function tone sequence decodes into a

channel number that is different from the currently set channel, the micro will output

the channel number on CH0 – CH7 for 250ms. This change may be latched into the T800

radios providing the sub-rack PCB channel select switches do not create a conflict.

As long as the DSP is detecting LLGT (indicated by a low level on TP300) the micro will

keep the transmitter keyed on. When the DSP fails to detect LLGT the micro turns off

the transmitter key and returns the DSP to the quiescent state.

When the T803 is programmed for keytone-only operation, the micro keying of the

transmitter follows the state of the TONE_DETECT line from the DSP.

In the quiescent state when the receiver mute line (RX_MUTE) goes low, the micro

instructs the DSP to gate audio from the receiver to Line-Out. If the line interface is 2-

wire, Line-In and Line-Out are joined and the Rx audio will pass through the line inter-

M8SL2-00-002-812 Circuit Operation D2.5

nally to the loudspeaker. It will therefore also reach the guard tone detector. Rx audio is

therefore notch filtered at the guard tone frequency to prevent false guard tone detec-

tion. If the line interface is 4-wire this filtering is unnecessary but the talk-through gate

must be turned on to send Rx audio to the loudspeaker. If the T803 is in repeater mode

the transmitter is keyed and will remain so until the RX_MUTE line goes high. Note that

the T803 will not key the transmitter if the receiver’s CTCSS is defeated (CD_OUT is

low) to prevent receiver channel noise being transmitted.

From the description above of the keytone/function tone detection it can be seen that

keying from line has priority over repeater mode keying and audio gating.

2.3 Alarm Monitoring

The T803 microprocessor monitors eight alarm sources:

•Transmitter forward power

•Transmitter reverse power

•low battery

•line fail

•four external closure alarms

When an alarm is triggered it is latched as indicated by the corresponding LED on the

front panel. If the T803 is keying the transmitter or sending receiver audio to the line the

latched alarm is ignored. Once the T803 re-enters the idle state the latched alarms are

actioned. The microprocessor reads the EEPROM to determine what tone sequence the

user programmed and instructs the DSP accordingly. If the tone sequence is to be sent to

the transmitter, it is keyed 500ms before the tones are generated. Additionally the user

may program any of the 4 auxiliary output ports as a response to an alarm event. The

micro will activate (pull low) these outputs if enabled. If several alarms are latched

together they are actioned in the order of priority:

1. External closure alarms 0 to 3

2. Reverse power

3. Forward power

4. Low battery

5. Line fail

If the programmed alarm action is a pip tone, the micro will instruct the DSP to append

200ms burst of 600Hz tone to each transmission (to line and/or radio).

Note: Sub-rack alarms (Fwd and Rev Power, Low battery or Line fail) cannot be

re-triggered until they are cleared. The 4 external closure alarms however

will re-send any user programmed tone sequence if re-triggered when

already latched.

D2.6 Circuit Operation M8SL2-00-002-812

2.3.1 Alarm Triggers

The alarms are triggered according to their type.

Table 2.1 Alarm Summary Table

External Closure Alarm (Auxiliary Input Alarms)

The 8 bit input latch (IC202) is sampled every 50ms. If two successive samples are the

same value then the state of the closure alarms is tested (This has the effect of debounc-

ing the alarm inputs). If any alarm is low then those alarms are latched.

RF Power Alarm

The forward and reverse power alarms are only tested when the T803 is keying the

transmitter. The alarms must be active (low) for two seconds before they are latched.

The two seconds sampling period allows for settling time inherent in some older T800

PA designs. Note that if a Transmitter fitted with a T1500-52-0000 PCB is being used,

rack backplane links LK1 and LK2 must be fitted at power up.

Low Battery Alarm

The 13.8V supply line voltage is measured by the A/D converter (IC208) every 50ms. If

the voltage is below the programmed alarm threshold (±0.05V) for more than 25 sec-

onds of a 30 second sampling period, the alarm is latched. The long sampling period

allows for load fluctuation effects on the supply.

Programmable low voltage threshold is only available in T803 firmware version 2.11 or

later. Prior to this, the threshold was fixed at 10.7V ±0.05V.

Line Fail Alarm

If no keying from line occurs within the period programmed by the user from

PGM800Win, the microprocessor latches this alarm, saves the mode status and puts the

T803 into repeater mode. Note that programming zero as the line fail time disables this

alarm.

2.4 Confirmations

Additional to alarms the T803 microprocessor also monitors eight non-alarm triggers

known as Confirmations:

•Power-up

•Channel change

•Up to six user defined function tone inputs

The T803 micro responds to a confirmation trigger in the same way as it does to an

alarm trigger – depending on what has been programmed into the EEPROM, a tone

sequence may be sent, an auxiliary output enabled and/or a pip tone enabled. These are

all actioned by the micro with the same rules as for alarm triggers. The only difference is

that there are no LEDs associated with confirmations.

If several confirmations are triggered together they are actioned in the following order

of priority: Power-up, Channel change and then User Confirmation 0 to 5. If several

alarms and confirmations are triggered together the Power-up confirmation, if enabled,

is always actioned first, followed by any alarms and then any other confirmations, both

in their normal priority order.

Note: Confirmations will re-send any user programmed tone sequence if re-trig-

gered.

2.5 Clearing Alarms and Confirmations

The alarms can be cleared by either pressing both front panel switches together or send-

ing the T803 a correctly programmed (“Clear Alarms”) function tone. All alarms are

cleared together. Clearing alarms turns off all LEDs, cancels any associated pip tones

and resets auxiliary outputs. If an alarm condition is still valid when it is cleared, it will

be re-latched and the user-programmed action will be executed. If required, pip tones

can be cleared separately (leaving alarms latched) by using a “Clear Alarm/Confirma-

tion Pip tones” function tone.

When the Line fail alarm is cleared, the T803 will revert to the mode it was in (Basesta-

tion or Repeater) before the alarm was triggered. A keying sequence from line can also

clear this alarm in the same way except that the pip tone will not be cleared if used by

other latched alarms. Line fail is the only alarm that can be cleared individually in this

way.

Confirmations can not be cleared by a single command like the Alarms. Confirmation

pip tones are cancelled by using a “Clear Alarm/Confirmation Pip tones” programmed

function tone and the auxiliary outputs are individually reset by using a “Turn OFF

Auxiliary output (x)” function tone.

It is possible to have more than one Alarm or Confirmation using the pip tone. In this

situation the clearing behaviour must be carefully considered:

•Line Fail Pip – Cleared by line keying-sequence only if pip tone is not ‘active’

for other Alarms and/or Confirmations.

D2.8 Circuit Operation M8SL2-00-002-812

•Alarm Pips (including Line Fail) – Cleared by “Clear Alarms” command only if

confirmation pips are not ‘active’. Always cleared by “Clear Alarm/Confirma-

tion Pip tones“ command.

•Confirmation Pips – Cleared by “Clear Alarm/Confirmation Pip tones” com-

mand.

Additionally, it is also possible to have a single auxiliary output assigned to more than

one alarm or confirmation. However, be aware that any command that resets auxiliary

outputs, such as “Clear Alarms” or “Toggle Auxiliary Output (x)”, will not make any

check for multiple use – auxiliary outputs will be reset regardless.

2.6 Voting Tone Operation

When the T803 is programmed to generate a tone on idle, the microprocessor monitors

the receiver Mute-In signal. When it is high (receiver muted) the DSP is instructed to

generate a voting tone to Line-Out. When receiver Mute-In is low the voting tone is

turned off. To prevent false detection of the idle tone at the far end voting equipment,

the DSP filters energy at the idle tone frequency from the receiver audio transmitted to

Line-Out.

If the T803 is programmed to generate a Sliding (or Simoco compatible) Voting Tone the

microprocessor reads the receiver RSSI level every 6ms using the A/D converter and

sends this value to the DSP. The DSP generates a voting tone to Line-Out. The tone fre-

quency is proportional to the RSSI level. To prevent incorrect operation of the far end

voting equipment, the DSP low pass filters the receiver audio transmitted to Line-Out.

3.1.2.1 Auxiliary Alarms Inputs

The T803-02 has 4 closure alarm inputs. On every falling edge the associated alarm is

(re)triggered, and sent when the T803 becomes idle. Alarm0 has higher priority than

Alarm3, in that the alarm will be actioned first.

Maximum input voltage = 5V

Note: The behaviour is different from the T803-00 as it will resend any user pro-

grammed tone sequence if re-triggered when already latched.

3.1.2.2 Auxiliary Control Outputs

The 4 Auxiliary outputs are of common collector type (they will only sink current), and

are rated to a maximum of 50V and 250mA. The outputs can be controlled via a function

tone sequence (Enable, Toggle, or Disable) or enabled on an alarm or confirmation.

3.1.3 Line Interface

The following table describes the pin configuration for interfacing with the T803 on

4-wire and 2-wire networks.

The T803 accommodates an input signal range of 28dB. Normally this is sufficient, how-

ever by shorting JP200 (found on the T803 PCB) an extra 15dB gain is added.

3.2 T803 Configuration

Before using the T803, line input (the level from the receiver) and output level (the level

presented to the radio transmitter) need to be properly configured.

Figure 3.2 T803 setup

The Line-In/Line-Out levels can be set up using either the programming application

(PGM800Win) or the test modes of the T803 (accessed via the buttons on the front panel.

See Section 3.2.3). The advantage of the test mode method is that it can provide a direct

test of the system. The programming method is required when access to the dispatch

console is difficult.

Using the test modes, the T803 levels are set up using actual signals present on the line.

For the Line-In level, the test tone and keytone, are generated by the dispatch console

and sent to the T803 via the leased line (or an audio generator could be used with the

line loss simulated). For the Line-Out level, the test tone is generated by the T803.

Programming the Line-In/Line-Out levels using PGM800Win does not require any con-

nection to the line. However, input/output specifications of the dispatch console and

actual line loss must be known so that the T803 levels can be properly calculated and

programmed.

Setting up receiver and transmitter levels can only be done using T803 test modes and/

or measurement. These levels are not programmable.

3.2.1 Equipment Setup for Level Configuration.

Configuring the T803 Line levels (using PGM800Win or Test Mode) and radio receiver

or transmitter levels requires the sub-rack and test equipment to be set up as shown

below.

Figure 3.3 Rack and test equipment setup

Remove any coaxial relay or duplexer in the T800 modules’ RF path and connect them

directly to an RF Test Set. Ensure that transmitter or PA RF output is sufficiently attenu-

ated to prevent damage to the test set.

Run up the receiver and transmitter as instructed in Part B and C of this manual.

3.2.2 Use of Test Microphone

The T803 test microphone is used to communicate both on air to radios and down the

line to dispatch consoles. It plugs into the RJ11 connector on the front panel which dou-

bles as a programming port. It is electrically connected in parallel with the receiver

(microphone with receiver audio and PTT button with receiver mute).

Most dispatch consoles are equipped with an intercom facility whereby speech can be

sent to line without a keytone. This enables the dispatcher to talk to service personnel at

the repeater site using the T803’s built in speaker without broadcasting speech to air.

The service personnel can talk back to the dispatcher using the T803 test microphone

(the PTT must be pressed to gate microphone speech).

Note: If the T803 is in repeater mode, PTT on the test microphone will key-on the

transmitter and thus broadcast test speech to air.

3.2.3 Test Modes

The T803 has three test modes to assist with setting levels:

•Test Tone Mode

•Line-In Level Configuration Mode

•Line-Out Level Configuration Mode1

To enter the test modes, press the Monitor and Mode Toggle buttons on the front panel

simultaneously for three seconds. The alarm LEDs will start flashing colours and travel-

ling up and down the display to indicate Test Tone Mode. The T803 will key-on the

transmitter and encode a 1kHz test tone to the transmitter for one minute. The test tone

can also be heard on the T803 speaker.

While still in Test Tone Mode, simultaneously pressing the Monitor and Mode Toggle

buttons briefly will change the mode to Line-In Level Configuration Mode. All the

LEDs will be on — either entirely red or entirely green.

•Green = Keytone present. T803 will key-on the transmitter.

•Red = No keytone present

While still in Line-In Level Configuration Mode, simultaneously pressing the Monitor

and Mode Toggle buttons again will change the mode to Line-Out Configuration

Mode1. To indicate this, all the LEDs will be orange.

Note: After entering each mode, a one to two second pause is required before

attempting the simultaneous press to enter the next mode (or to exit).

While in Line-In or Line-Out Configuration Mode, the Monitor and Mode Toggle but-

tons operate as ‘gain’ adjust buttons. A short press on the Monitor button will increase

the Line-In/Line-Out gain and toggle the top alarm LED on or off, indicating a level

increase. The LED will no longer toggle (it will stay on) when the top of the range has

been reached. Conversely the Mode Toggle button will decrease the gain and toggle the

bottom alarm LED. Again, the LED stays on when the bottom of the range has been

reached. In both of these modes Line-In audio can be heard on the monitor speaker.

To exit Line-Out Configuration Mode, briefly press both buttons again. Alternatively,

the unit will automatically return to normal operation mode after one minute. (This

occurs in all three test modes).

Note: These levels are always preserved on exit. Take care not to change them

unintentionally during simultaneous button press.

1. Line-Out Configuration Mode is only available in T803 firmware version 2.07 or later.

For firmware versions prior to 2.07, a simultaneous button press while in Line-In Con-

figuration Mode will exit Test Mode .

3.2.4 Level Configuration

Before proceeding with any level configuration the transmitter and receiver must be

run-up and configured for the application. Also, ensure that the equipment has been set

up correctly as indicated in Section 3.2.1. It is important that the T800 Transmitter out-

put is connected to the Test Set (through an attenuator as required) because it will often

be keyed during these level setting procedures.

The following levels need to be set:

•Tx Audio – Audio level from T803 to transmitter (balanced)

•Line-In level

•Rx Audio – Audio level from receiver to T803 (unbalanced)

•Line-Out level

The only consideration of order is that the Tx Audio level needs to be configured before

the Line-In level can be done.

The level of audio received from the T803 is adjusted at the input of the transmitter.

1. Set the T803 into Test Tone Mode (See Section 3.2.3)

2. Adjust the Line Sensitivity Control on the front panel of the transmitter to give a

reading on the RF Test Set of 60% full system deviation (compensate for any

CTCSS tone deviation).

3.2.4.2 Line-In Level

The Line-In level can be set up in two ways:

•On the T803 in Level Configuration Mode

•Using PGM800Win programming software.

Using Level Configuration Mode:

Note: The Tx audio level must be set up before starting this procedure (Section

3.2.4.1).

1. Set the T803 into Line-In Level Configuration Mode (See Section 3.2.3).

2. Connect a dispatch console to the far end of the line, or simulate the console and

line loss using an audio generator.

3. Press the PTT on the dispatch console. This will send a keytone to the T803.

Ensure the console also sends a test tone at speech level to line (this tone is

required for this method of configuring the Line-In level).

4. The alarm LEDs on the front panel of the T803 should change to green (indicating

that a keytone has been detected) for as long as the PTT is pressed.

5. Adjust the Line-In level by pressing the Monitor button (increases the level) or the

Mode Toggle button (decreases the level) until the transmitter deviation reading,

monitored on the RF Test Set, indicates 60% full system deviation (compensate for

any CTCSS tone deviation).

6. Press the PTT on the dispatch console again, but this time use speech instead of

the test tone. Ensure the LEDs on the T803 remain constant on green during

speech transmission. If not see Section 3.3.1 (point 7) on how to troubleshoot for

Talkoff.

D3.12 Installation and Configuration M8SL2-00-002-812

Note: The monitor speaker is forced on in this mode so that the test-microphone

may be used as an intercom to communicate to the dispatcher room (See

Section 3.2.2).

Using PGM800 software:

1. Determine the output level of the console. This may be a preset or default value

specified in the console’s manual or a value programmed by the operator.

2. Determine the actual line-loss between the console and the T803.

3. Calculate T803 Line-In Level as follows:

T803 Line-In Level = console output level (dBm) – Line-loss (dB)

4. Program the T803 with the calculated level.

Example case:

Console output level =–13dBm

Measured Line loss = 6.5dBm

T803 Line-In level =–13 – 6.5 = –19.5dBm

3.2.4.3 Rx Audio – Audio Level from Receiver to T803

The Rx Audio level is adjusted using either the Line Level control on the front of the

receiver or the RV2 potentiometer on the backplane, depending on the configuration of

the link LN8 on the backplane.

The recommended (and default) configuration of LN8 is with pins 2–3 and 4–5

linked. With this configuration the balanced audio from the receiver (Rx-Line-1 and Rx-

Line-4 ) is changed to unbalanced audio for the T803 (this means the Rx Line output can

no longer be used as direct balanced audio to the transmitter). The level to the T803 is

adjusted using the Line Level control on the front of the receiver. The advantage of

using this path is that it allows CTCSS filtering to be applied (using the receiver’s inter-

nal CTCSS filter. See Section 3.5 in Part B).

Alternatively if CTCSS is not used, the receiver unbalanced audio output (Rx-Audio-1)

can be used to provide audio to the T803 by linking pins 1–2 on LN8. In this case the

level to the T803 is adjusted using the RV2 potentiometer on the backplane. This audio

path is not suitable for CTCSS systems because complete CTCSS filtering cannot be

applied. The only filtering directly available is the optional receiver de-emphasis filter-

ing. See Section 3.5 in Part B. The T803 does however apply a 160Hz to 3kHz high pass

filter resulting in an overall audio response for this path very similar to the default high

pass filtered receiver balanced Line output. See the table below.

M8SL2-00-002-812 Installation and Configuration D3.13

The table above shows that configuring LN8 with links 2–3 and 4–5 could be used for

systems with or without CTCSS. Configuring LN8 with link 1–2 in normally only used

with systems without CTCSS on the Rx audio.

Procedure

Before commencing this procedure set up the receiver audio processing, such as de-

emphasis and CTCSS filtering, as required for the application. See Section 3.5 in Part B.

This is important for the T803 Telecom line compliance. See the Caution below.

CAUTION: The Rx audio level must not exceed 230mVrms at 60% full system devia-

tion. This will ensure that the actual T803 Line-Out level corresponds

to the programmed value and thus ensures levels do not exceed the

power level requirements of the Telecommunications line.

There are three possible ways to monitor the Rx Audio level during adjustment:

•Direct measurement of receiver audio on the backplane

•Indirectly, using transmitter deviation

•Indirectly, using the T803 Line-Out level

Direct measurement of receiver audio on the backplane:

1. Use the RF Test Set to generate an on-channel signal to un-mute the receiver.

2. Modulate the RF carrier with a 1020Hz tone1 at 60% full system deviation, adding

CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the

receiver as required for the application. See Section 3.5 in Part B).

3. Monitor the audio level from the receiver on the X800-56-PCB3 backplane at pin2

of LN8, with the links (jumpers) in place as directed in Section 3.1.1. Use a high

impedance meter such as an oscilloscope for the measurement.

D3.14 Installation and Configuration M8SL2-00-002-812

4. For LN8 with pins 2–3 and 4–5 linked, adjust the line level control on the front of

the receiver for an audio level of 230mVrms.

For LN8 with pins 1–2 linked, adjust RV2 on the backplane for an audio level of

230mVrms.

Using transmitter deviation:

This method is not suitable for simplex configured repeaters.

1. Use the RF Test Set to generate an on-channel signal to un-mute the receiver.

2. Modulate the RF carrier with a 1020Hz tone1 at 60% full system deviation, adding

CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the

receiver as required for the actual working system. See Section 3.5 in Part B).

3. Put the T803 unit into Talk Through Mode (also known as Repeater Mode) using

the Mode Toggle button1. The Mode LED should be red, constant or flashing, and

the transmitter should be keyed on.

4. For LN8 with pins 2–3 and 4–5 linked, adjust the Line Level control on the front

of the receiver to produce 60% full system deviation at the transmitter RF output

as measured on the test set.

5. For LN8 with pins 1–2 linked, adjust RV2 on the backplane to produce 60% full

system deviation at the transmitter RF output as measured on the test set.

Note: De-Emphasis should be off on the test set receiver.

Using the T803 Line-Out level:

1. Use the RF test set to generate an on-channel signal to un-mute the receiver.

2. Modulate the RF carrier with a 1020Hz tone2 at 60% full system deviation, adding

CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the

receiver as required for the actual working system. See Section 3.5 in Part B).

3. Put the T803 into Base Station Mode using the Mode Toggle button1. The Mode

LED should be green (constant or flashing).

4. For LN8 with pins 2–3 and 4–5 linked, monitor the T803 Line-Out level (600Ω bal-

anced audio) and by adjusting the Line Level control on the front of the receiver,

set this level to equal the programmed ‘Line-Out Level’ as set in PGM800Win.

For LN8 with pins 1–2 linked, monitor the T803 Line-Out level (600Ω balanced

audio) and by adjusting RV2 on the backplane, set this level to equal the pro-

grammed ‘Line-Out Level’ as set in PGM800Win.

1. The Mode Toggle button may be disabled from PGM800Win

2. A 1020Hz tone is used (rather than 1kHz) because some Test Sets can produce unstable

deviation readings

M8SL2-00-002-812 Installation and Configuration D3.15

3.2.4.4 Line-Out Level

The Line-Out Level can be set up in two ways:

•On the T803 in Level Configuration Mode

•Using PGM800Win programming software (version 4.02 or later).

Using Level Configuration Mode (T803 firmware version 2.07 or later):

1. Set the T803 into Line-Out Level Configuration Mode (See Section 3.2.3).

2. Use the RF Test Set to generate an on-channel signal to un-mute the receiver.

3. Modulate the RF carrier with a 1020Hz tone at 60% full system deviation, adding

CTCSS tone if necessary (ensure that CTCSS tone is removed from the receiver

audio output by selecting the correct links inside the receiver).

4. Monitor the T803 Line-Out level and adjust by pressing the Monitor button

(increases the level) or the Mode Toggle button (decreases the level) until the level

is acceptable at the dispatch console.

Note: The monitor speaker is forced on in this mode so the test-microphone may

be used as an intercom to communicate to the dispatcher room (See Section

3.2.2).

Using PGM800Win software:

1. Determine the input level required at the dispatch console. This may be a preset or

default value specified in the console’s manual or a value programmed by the

operator.

2. Determine the actual line-loss between the console and the T803.

3. Calculate T803 Line-Out Level as follows:

T803 Line-Out Level = console input level (dBm) + Line-loss (dB)

4. Program the T803 with the calculated level.

Example case:

Console input level = –13dBm

Measured Line loss = 6.5dBm

T803 Line-Out level = –13 + 6.5 = –6.5dBm

3.3 Fault Finding

1. Connect the T803 to its companion dispatch console via the leased line. Check that

speech sent from the console can be heard on the T803 speaker (un-mute speaker

if required).

D3.16 Installation and Configuration M8SL2-00-002-812

One possible cause of incorrect operation is that the line connections have become

transposed in the wiring network or that the dispatch terminal uses different

Send/Receive pairs.

2. Use the dispatch console to key-on the transmitter. If the transmitter does not key-

on, check that the console and T803 have been compatibly programmed.

•check 2-wire or 4-wire

•check the keytone frequency

•check if function tones are used

•check high level guard tone and function tone periods (if used) are the same

Finally check that the console is sending appropriate signal levels and that tone

durations are correct (which are often variable), and that the line is not causing

unacceptable attenuation or distortion.

3. If the console can key the transmitter but not change Repeater/Basestation Mode,

auxiliary outputs, receiver defeat or cancel alarms, carry out the checks in Step 2

above, but pay particular attention to the function tone programming.

If changing channels is a problem check that the appropriate channel selection

DIP switches (SW1) on the rack backplane are off.

3.3.1 Troubleshooting

1. Sometimes misses function tone command

Set up the Line-In level so that the function tones are about 2Vpp at TP204.

2. Misses function tone sequence on very fast key repetition

A minimum of 200ms pause is required between pressing buttons on the console. Some

consoles do not limit the maximum keying rate.

3. PGM800Win: “Warning: the Firmware version is not compatible. Data read

maybe incorrect”

This warning occurs when reading the T803 with an old version of PGM800Win.

This can be ignored as the T803 unit is backwards compatible. However, it is recom-

mended to use the latest PGM800Win with full T803 support.

4. Loop-Line functionality (also known as Loopback)

Loopback can be enabled in PGM800Win. It is then activated by sending the T803 the

programmed function tones.

M8SL2-00-002-812 Installation and Configuration D3.17

5. While in Line-In Level Configuration Mode, the LEDs flash green only briefly

when the dispatch console PTT is pressed

The Line-In level is too low. The T803 is only detecting the high-level guard tone

(HLGT).

While still in Line-In Level Configuration Mode, activate the console PTT and adjust the

Line-In level by pressing the Monitor button (increases the Line-In level) until the LEDs

remain constant green. The top alarm LED will toggle on and off, indicating a level

increase until the top of the range is reached (may be as many as 65 presses). If this still

fails, open up the unit and add JP200, and try again.

6. When the PTT is pressed, a pulsing sound can be heard from the speaker

The Line-In level is too high. The function tones can not be decoded properly hence it

keys off.

While still in Line-In Level Configuration Mode, activate the console PTT and adjust the

Line-In level by pressing the Mode button. The bottom alarm LED will toggle on and

off, indicating a level decrease until the bottom of the range is reached. Using an oscillo-

scope measure the signal on TP204 – the function tone level should be about half the

level of the high level guard tone.

7. The console keys the transmitter correctly except when speech is present

This is known as ‘Talkoff ’ and occurs when the difference between the keytone level

and speech peak level exceeds specification (32dB in 2-wire mode and 35dB in 4-wire

mode), causing the keytone detection to fail.

For reliable operation, the keytone level should be no more than 35dB lower than peak

speech level.

If it is not possible to adjust the levels at the console, decrease the programmed Line-In

level of the T803 until talkoff is eliminated. This requires that the audio level from T803

to transmitter will also need to be re-adjusted (using the transmitter’s Line Sensitivity

control) to maintain 60% full system deviation for the test tone sent from the console.

Adjust the relative audio levels (keytone and speech) sent from the dispatch console.

8. Keytone Falsing in 2-wire mode

When operating in 2-wire mode with lossy lines (i.e. significant separation required

between T803 Line-In and Line-Out levels) the keytone detector can become de-sensi-

tised by noise.

•Check to ensure that the input level from the receiver is correctly set up at

230mVrms (See Section 3.2.4.3).

•Check the receiver mute open level (squelch). If necessary adjust the receiver Gat-

ing Sensitivity control on the front panel of the receiver, so that the receiver mute

opens at a higher SINAD level (12dB or preferably greater). This has the effect of

reducing the noise on the line input of the T803 in 2-wire mode.

D3.18 Installation and Configuration M8SL2-00-002-812

•If there is still a problem after the squelch gating level has been adjusted as much

as practicable, it becomes necessary to reduce the separation between the T803

Line-In and Line-Out levels. This separation may need to be reduced to less than

8dB for 12dB receiver audio SINAD (or less then 12dB for 14dB receiver audio

SINAD). To achieve this, adjust the relative input and output levels of the dispatch

console. Again, this has the effect of reducing the noise on the line input of the

T803.

If the above solutions do not help resolve the problem, the 2-wire line loss may be too

severe and unacceptable for normal 2-wire T803 operation. In this case an external hard-

ware solution involving a notch filter fitted to the receiver audio path (TA1086-01) and a

2-wire/4-wire hybrid fitted across the line may be required. This solution has been veri-

fied and documentation is available detailing how to install the TA1086-01. Contact

your your nearest Tait Dealer or Customer Service Organisation for more information.

4.1 Introduction

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note: It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The mechanical and miscellaneous section lists the variant and common parts in IPN order.

Grid Reference Index

This section contains a component grid reference index to help you find components and labelled

pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alpha-

numeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams

Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric

border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers

for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is

spread over two or more sheets.

When a line representing part of the circuitry is discontinued, a reference will be given at the end of

the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to

the sheet number and the last two characters refer to the location on that sheet of the continuation of

the circuit (e.g. 1R3).

Part E T850 VCO PCB Information

This part of the manual provides the parts list, PCB layouts and circuit diagram for the T850 VCO

PCB. There is a detailed table of contents at the start of Section 2.

1 Introduction

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note: It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The mechanical and miscellaneous section lists the variant and common parts in IPN order.

E1.2 Introduction M8SL2-00-002-812

Variant Components

A variant component is one that has the same circuit reference but different value or specification in

different product types. Variant components have a character prefix, such as “&”, “=” or “#”, before

the circuit reference (e.g. &R100).

How To Use This Parts List

The components listed in this parts list are grouped in alphabetical order and then in numerical order within each group. Each compo-

nent entry comprises three or four columns: the circuit reference, variant (if applicable), IPN and description. A number in the variant

column indicates that this is a variant component which is fitted only to the product type listed.

2 Power Supply Description

2.1 Introduction

The T800-23-0011 power supply consists of a Power Supply Unit (PSU) Module, connec-

tors, and ferrite filters. These components are shown in Figure 2.1 below.

F2.2 Power Supply Description M8SL2-00-002-812

2.1.1 PSU Module

The PSU module used in the T800-23-0011 power supply has over temperature, current

overload and overvoltage protection. Refer to Section 1.2 for specification details.

Overvoltage applied on the module’s output will cause the module to shutdown. To

reset the module, remove the mains supply to the T800-23-0011, allow 30 seconds for

charges to leak away, and then reconnect the T800-23-0011.

The module is protected from current overload by a voltage foldback method. If the

load on the output starts drawing more current than the specified maximum, the volt-

age will start dropping away. This condition will recover automatically when the load is

removed or returns to normal.

Over temperature will cause the module to shutdown. It will recover automatically

when it has cooled down to an acceptable operational temperature.

Caution: Correct mounting of the T800-23-0011 power supply is important: Refer to

Section 3.3 for ventilation guidelines. Ignoring these conditions may cause

the module to overheat, and consequently, to shut down.

2.1.2 Internal Loom

Mains power to the PSU module is supplied via an IEC plug on the rear panel and then

filtered by a ferrite bead (shown in Figure 2.1). The mains ground line is filtered by a fer-

rite bead and then connected to the T800-23-0011 chassis and to the PSU module’s float-

ing ground contact.

The PSU module’s output is filtered by a ferrite sleeve on the positive line, and then

interfaces to the SL2 backplane via a Molex connector on the T800-23-0011 rear panel.

Additionally a ‘feed-through’ loom is connected to the Molex connector. This loom

forms part of the path for the programming and speaker connection between the SL2

backplane and the SL2 front panel. The external cable connection between the

T800-23-0011 and the SL2 backplane completes this path.

For the wiring diagram, refer to Section 6.2.1.

M8SL2-00-002-812 Installation Guidelines F3.1

3 Installation Guidelines

The following section gives a brief description of the basic rack mounting and wiring

procedures.

3.1 General

The T800-23-0011 is supplied mounted to the SL2 front panel by four M3x10 button hex

screws.

A small cable extending out of the front of the T800-23-0011 plugs onto to the SL2 front

panel. This cable forms part of the programming and speaker connection between the

SL2 front panel and the backplane. The external cable connection between the

T800-23-0011 and the SL2 backplane provides the DC power supply to the basestation

and also incorporates 3 wires completing the programming and speaker connection.

Warning: FUSE

The cable connecting the T800-23-0011 DC power output to the backplane

also includes a fuse. This fuse is critical to the IEC 60950 safety compliance

of the T800 SL2 Base Station and must be replaced with the same component

or compliance will be voided.

The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A (60VAC)

For the AC mains input connection of the T800-23-0011 use only an IEC type detachable

power supply cord (with a moulded IEC connector). Ensure that it has a current rating

of at least 5A.

3.2 Connector Pinouts

The pinouts for the AC mains input connector and the DC output connector on the rear

of the T800-23-0011 are shown in Figure 3.1 below.

3.3 Equipment Cooling

Although the T800-23-0011 is a high efficiency switching power supply, a considerable

amount of heat is generated during normal operation. An adequate flow of cooling air is

therefore essential for reliable operation.

Caution: Do not operate this unit in a completely enclosed cabinet.

It is estimated that the average life expectancy of this unit will double with every 10°C

drop in ambient temperature. It is therefore recommended to:

•Keep the ambient temperature low.

•Ensure that airflow is not restricted.

M8SL2-00-002-812 Functional Testing F4.1

4 Functional Testing

The following test procedures will confirm that the T800-23-0011 has been set up and

adjusted correctly and is fully operational. Refer to Figure 4.1 for test equipment details.

Figure 4.1 Test equipment setup

4.1 Basic Operation

To confirm the basic operation of the power supply, proceed as follows.

•Ensure that the main supply to the T800-23-0011 is switched off. Set up the

test equipment as shown in Figure 4.1.

•Set the output DC load to maximum resistance/minimum current.

•Connect the T800-23-0011 to the mains supply and switch it on.

•Vary the DC load and check that the output voltage and current are within

the specifications (refer to Section 1.2.4).

4.2 Output Current Overload

To confirm the operation of the current overload protection circuitry, proceed as follows.

•Ensure that the main supply to the T800-23-0011 is switched off. Set up the

test equipment as shown in Figure 4.1.

•Set the output DC load to draw approximately 11A.

•Switch on the mains supply and slowly decrease the load resistance, thereby

increasing the current until voltage foldback occurs. The current should not

rise above the Current Overload Limit (refer to Section 1.2.4), but voltage

should drop away.

4.3 Output Noise

To check that output noise is within specification, proceed as follows.

•Ensure that the main supply to the T800-23-0011 is switched off. Set up the

test equipment as shown in Figure 4.1. Connect the T800-23-0011 to the

mains supply and switch it on.

•Connect a digital voltmeter (e.g. Fluke 77) across the load terminals and set

the meter to its lowest AC volts range.

•Check that the reading is less than 100mVpp under all load and line condi-

tions.

Note: A real reading of the level of noise present on the output of a switching

power supply is very difficult to obtain, as low noise levels, common mode

noise paths and ground loops all lead to inaccurate measurement results.

The procedure outlined above will, however, give a good indication of the

output noise.

4.4 Overall Power Supply Stability

To check for overall PSU stability, proceed as follows.

•Ensure that the main supply to the T800-23-0011 is switched off. Set up the

test equipment as shown in Figure 4.1. Connect the T800-23-0011 to the

mains supply and switch it on.

•Connect the oscilloscope across the output.

•Vary the mains voltage and DC load over the full specified range (refer to

Section 1.2).

•Check on the oscilloscope that no oscillations occur.

strongly recommended that the mains supply to the whole of the repair and test area is

supplied via an earth leakage circuit breaker.

6.1.2 Warning: Fuse

The cable connecting the T800-23-0011 DC power output to the backplane also includes

a fuse. This fuse is critical to the IEC 60950 safety compliance of the T800 SL2 Base Sta-

tion and must be replaced with the same component or compliance will be voided.

The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A (60VAC)

6.1.3 Caution: Handle With Care

Although this is a lightweight unit, it contains a number of quite heavy and fragile indi-

vidual components which are mounted directly on the PCB. Severe mechanical shock

may damage the PCB (e.g. solder joints, copper tracks) and/or components (e.g. fragile

ferrite magnetic materials).

1.2 Mounting

The T800SL2 unit is shipped ready assembled for fitting into racks. All that is required is

for the connection of suitable cables.

1.3 Power Supply

The power rating information for the T800SL2 with the Tait supplied power supply

module (T800-23-0011), is provided on the label located on the top cover as visible in

Figures 1.6.

The power rating information for the T800SL2 for use with a customer supplied DC

power source, is provided on the label located on the top rear of the Transmitter mod-

ule.

In order to comply with the safety requirements of EN60950, the power supply module

used with the T800SL2 must be provided with an easily accessible mains disconnect

device compliant with IEC61058, such as a switch or circuit breaker. This provides the

means to rapidly disconnect the mains power in an emergency.

All Tait supplied racks incorporate a power distribution board with a circuit breaker

easily accessible in the back of the rack, on the lower right hand side (viewed from the

rear). The circuit breaker will disconnect the mains to the entire rack. If only one channel

needs to be mains-isolated and the Tait power supply module is T800-23-0011, then it is

acceptable practice to pull the IEC connector directly out of the power supply module.

If a customer supplied power source is used, it must have the following features:

•An easily accessible and safety compliant mains disconnect device.

•The capability to provide enough current to drive the T800 system.

•Free from excessive ripple or noise.

•Meets all EMC and safety regulations for the intended market.

G1.2 M8SL2-00-002-812

The entire system should be protected by the use of appropriately rated fuses in the

power supply.

Note: It is particularly important when the prime power source is a battery that fuses be

employed in all the supply lines.

Warning: Fuse – DC powered Base Stations

The cable supplied for connecting a DC power source such as a battery to

the backplane of the SL2 Base Station, includes a fuse. This fuse is critical

to the IEC 60950 safety compliance of the T800 SL2 Base Station and must

be used or compliance will be voided. If the fuse has blown it must be

replaced with the same component

The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A

(60VAC)

1.4 Reverse Polarity and Overvoltage Protection

A crowbar diode is fitted to all T854 transmitters for protection against connection to a

power supply of incorrect polarity. It also provides overvoltage protection from voltage

transients caused by lightning strikes.

Note: A fuse must be fitted in the power supply line for the diode to provide effec-

tive protection.

1.6 RF Coax Cable and N-Type Connector

Make sure the RF coax cable to the N-type connector is free from sharp bends or twists.

If access to the rear of the rack frame is restricted, the cable should be long enough to

allow the slimline assembly to be fully withdrawn from the cabinet.

Make sure that any N-type plugs connected to Tait equipment are assembled according

to the manufacturer’s instructions. It is particularly important that the centre pin in the

plug is positioned correctly:

•if the pin is positioned too far back in the plug, it may not make good contact

with the socket;

•if the pin protrudes too far (as shown in Figure 1.5), or is not straight, it may

damage the socket when the plug is screwed in.

M8SL2-00-002-812 T854 Optional Features G2.3

The line transformer is designed to provide a balanced interface to 600Ω lines, con-

nected between LINE I/P 1 and LINE I/P 4. When %T210 is fitted, the two centre con-

nections (LINE I/P 2 and LINE I/P 3) are shorted together for normal operation. With

the other options these two centre connections are available to the user via P204 and

P208, unless a centre-tapped %T210A or %T210B is used, wired to LINE I/P 3.

The secondary winding of the transformer is connected via 1kΩ (R202) and 10Ω (R160)

resistors to pin 6 (AUDIO-2) of D-range 1 and may be used to monitor audio on the line.

Pin 7 of D-range 1 can be reconfigured as AUDIO-1 by removing R808 and R160, and

placing %R150. Note that this configuration does not allow external programming of

the module

%R203C and %R203D have replaced SL201 and SL202.

To retain the DC loop keying keying facility, there is a centre-tapped version of the

ETAL leaded and SMD transformers, the P2602 and P2782 respectively. This will only

work for Common Earth systems. If full isolated DC loop keying is required, then the

T4030 must still be used. The T4030 must also be used if the Transmitter is to be used as

half of a 2-wire to 4-wire hybrid.

put is available on pin 9 of the T800-03-0000 auxiliary D-range connector (D-range 2).

2.5 Local Microphone

Use of the local microphone (via the front panel stereo socket) will disable the audio

input from the line. The audio switching occurs when the PTT switch is closed.

2.6 Keying With Option PCBs

If an option PCB is fitted, the exciter may be keyed via the TX-ENB-OPT pad in the

audio processor. The line must be pulled low to key.

2.7 Transmit Key Time

(Refer to the appropriate test points and options connections drawing in Section 6 in

Part C.)

A solder link (SL501) is provided on the bottom of the PCB to allow two transmit key

time options, as shown in the table below.

*In this configuration the standby spurious emissions should be <–65dBm.

2.8 Local PTT Indication for A800 SIM

This option allows the use of D-range 1 pin 3 for an external PTT indication when the

mic PTT or carrier switch is activated. Used for A-800 SIM or any other external control

or CTCSS unit.

2.9 Direct input to Buffer option

A direct input for data use. Note that this input will have 4.5V half-rail, and needs isola-

tion unless R289 is also removed. Leaving R291 as 0Ω and removing &R290 may

improve data shape (less overshoot), as &C289 is still in circuit.

2.10 Line Input Control Replacement

The Line Input control can be replaced with fixed resistors if required.

M8SL2-00-002-812 Talk Through Repeater G3.1

3 Talk Through Repeater

In this configuration the receiver directly keys the transmitter when the signal is

received. The demodulated audio is fed via 600Ω lines to the transmitter to modulate

the carrier. The receiver and transmitter operate simultaneously and must therefore be

on different frequencies. The minimum frequency separation depends on the duplexer

used.

4.11 General

This installation contains a transmitter and receiver which may or may not be on the

same frequency, thus simultaneous transmission and reception is not possible. When

the transmitter is keyed, the coaxial relay is also energised. When the relay is in its rest

position, signals from the antenna are passed to the receiver and the demodulated out-

put is fed via 600Ω lines to the RCU.

The receiver is disabled when the transmitter is energised to prevent the receiver mute

opening from RF due to lack of isolation in the relay, direct radiation or the noise skirt of

the dual frequency link.

Since the base station may be controlled via a 2-wire line and a 4-wire to 2-wire hybrid,

there is a possibility of system oscillation if the receiver is not disabled during transmit.

This occurs when the transmit energy enters the receiver and produces an audio

response which can pass from the receive to the transmit audio part of the hybrid

(impedance imbalance, etc).

Note: This configuration is only possible when transformer %T210 and T4030 are

fitted. Refer to Section 2.2.

4.12 Transmitter Tail Timer

If the transmitter has the tail timer enabled:

•the receiver disable timer must be set so that tRx/Dis > tTx/Tail;

Figure 4.5 Receiver Disable Time vs Tail Time

•if the system configuration also uses an aerial changeover relay as well as the tail

timer, the changeover relay must be driven from the relay driver (Q250) in the

audio processor, rather than by Tx-Key or Tx-Enable; this output is available on

pin 9 of the T800-03-000 auxiliary D-range (D-range 2);

•depending on tail time requirements, it is possible for the transmitter tail time to

exceed the receiver disable time capability; in this situation the receiver disable

line should also be driven from relay driver Q250 (D-range 2 pin 9).

M8SL2-00-002-812 DC Line Keying G5.1

5 DC Line Keying

Where the transmitter and receiver are separated by only a short distance and DC isola-

tion is not required, DC loop keying may be employed.

Note: This feature is not available with standard line transformer ETAL P2781

(%T201B). Refer to Section 2.2.

A small DC current (usually less than 10mA) can be fed via the balanced 2-wire line to

provide remote control of various functions.

In a duplex system the receiver mute is used to key a transmitter, provided there is a

common earth between the two units (refer to Figure 5.6).

Figure 5.6 DC Loop Keying With Common Earth

Where the receiver and transmitter (or remote control) are distant, DC loop keying is

provided by an isolated supply, driver and detector because an earth cannot be relied on

(refer to Figure 5.7, Figure 5.8 and Figure 5.9).

6.1 Introduction

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note: It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The mechanical and miscellaneous section lists the variant and common parts in IPN order.

Grid Reference Index

This section contains a component grid reference index to help you find components and labelled

pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alpha-

numeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams

Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric

border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers

for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is

spread over two or more sheets.

When a line representing part of the circuitry is discontinued, a reference will be given at the end of

the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to

the sheet number and the last two characters refer to the location on that sheet of the continuation of

the circuit (e.g. 1R3).

The T800-09-0001 is an RF coaxial relay assembly fitted with three female N-type con-

nectors, and comes complete with a mounting bracket and two coaxial cables termi-

nated in male N-type connectors. It can be used, for example, in base station

applications where the receiver and transmitter share the same antenna, in which case it

can be driven by the T800 SL2 transmitter relay driver (refer to Section 2.4 in Part G for

more information).

T800-01-0010 Calibration Test Unit

The T800-01-0010 provides all inputs and outputs necessary to carry out the full tuning

and adjustment procedure for T800 Series I and II receivers, exciters and transmitters. It

provides a convenient method of connecting test equipment, including a PC and power

supply, to a T800 Series I or II module (via D-range 1) without the need to construct cus-

tom wiring looms.

The T800-01-0010 also has a built-in speaker, a switch for selecting Series I or II modules,

and uses standard BNC and “banana plug” sockets.

T800-03 Auxiliary D-Range

The T800-03 is an additional D-range kit comprising one D-range plug assembly and

two locating pins, nuts and washers. Although originally a T800 Series I ancillary, it can

be used in T800 SL2 products for special applications requiring custom internal wiring.

T800-03-0000 Auxiliary D-Range

The T800-03-0000 is an additional D-range kit (normally fitted as D-range 2) comprising

one D-range plug assembly complete with connecting loom and mounting screws. The

ribbon cable loom connects the D-range PCB to the Micromatch socket (SK805) in the

microcontroller compartment. Typical uses of the T800-03-0000 are in paging applica-

tions and where external channel control is required. Refer to Figure 1.4 in Part G for the

T800-03-0000 pin connections.

T800-04-0000 RSSI

The T800-04 RSSI option PCB plugs directly into the main PCB (support circuitry being

fitted as standard). It is fitted to the T855, T875 and T885 whenever receiver signal

strength monitoring is required, e.g. trunking or voting. Its function is to provide a DC

voltage proportional to the signal level at the receiver input.

T800-10-0000 Channel Select PCB

The T800-10-0000 is a small PCB that plugs into the Micromatch connector (SK805) in

the microcontroller compartment of a T800 SL2 receiver, exciter or transmitter. It is fitted

with an eight-switch DIP switch which allows the manual selection of any one of the

channels already programmed into the module by PGM800Win. The T800-10-0000 is

also fitted with a Micromatch socket to provide access to SK805 for programming pur-

poses.

T800-80-0000 Local Microphone

A 600Ω microphone complete with 300mm cord terminated in a ¼” stereo plug for use

with the T854.

T800-80-0001 T803 Microphone

A 600Ω microphone complete with 300mm cord terminated with a RJ11connector for

use with the T803.

1.3 Paging

T800-30-0000 and T800-30-0002 DFSK Modulators

The T800-30-0000 (formerly T800-30) and T800-30-0002 (formerly T800-35) are DFSK

modulators for T800 SL2 transmitters, suitable for POCSAG or similar paging data for-

mats. Analogue transmissions (e.g. tone or speech) are still possible by disabling the

data path via a control line. 512 or 1200 baud data rates are link selectable. The

T800-30-0002 is adapted for use with an external reference oscillator for simulcast trans-

mission. The T800-30-0000 and T800-30-0002 are not designed for use with 66 to 88MHz

equipment.

T800-32-0000 and T800-32-0010 DFSK Modulators

The T800-32-0000 and T800-32-0010 are DFSK modulator PCBs which can be fitted to

T800 SL2 transmitters to enable them to function as low-speed paging transmitters.

These new PCBs have been specifically designed for Series II transmitters and are much

easier to fit into the latest design transmitters.

Both PCBs are suitable for POCSAG or similar paging data formats, but are not

designed for analogue transmissions (e.g. tone or speech). The T800-32-0010 is adapted

for use with an external reference oscillator for simulcast transmission. The

T800-32-0000 and T800-32-0010 are not designed for use with 66 to 88MHz equipment.

1.4 External Frequency Reference

T800-06-0000 External Frequency Reference Kit

The T800-06-0000 kit provides an additional D-range plug/PCB assembly which incor-

porates a miniature RF connector to carry an externally generated 12.8MHz reference

signal into a T800 SL2 module. This enables the use of very high stability external refer-

ence oscillators for special applications.

The D-range PCB is also fitted with a Micromatch socket which can be connected to

SK805 in the microcontroller section via the supplied loom to provide access to the

channel change lines.

The kit comes complete with fitting instructions and all installation hardware.

T800-06-0001 External Frequency Reference Kit

The T800-06-0001 is the same as the T800-06-0000 kit with the addition of a special coax

cable for external frequency reference input. One end of this coax is terminated with a

miniature RF connector which fits into the D-range socket in an appropriate backplane

PCB to connect to a T800 SL2 module fitted with a T800-06-0000 kit. The other end is ter-

minated with a BNC connector which can be mounted on the rack frame.

T801-00 Frequency Reference Module

The T801-00 frequency reference module provides a high stability frequency source to

which the synthesiser within a T800 SL2 base station can be locked. The master standard

within the T801-00 is primarily intended to be rubidium, although high quality oven-

ised crystal oscillators can also be used in applications where more frequent readjust-

ment of frequency is acceptable. The T801-00 converts the output frequency from its

master standard to the 12.8MHz required by the T800 SL2 base station.

Refer to M801-00.

T801-10 OCXO Module

The T801-10 OCXO module provides a high stability frequency source to which the syn-

thesiser within a T800 SL2 base station can be locked. This will provide T800 SL2 trans-

mitters with the frequency stability required for simulcast transmission. The master

standard within the T801-10 is a high quality ovenised crystal oscillator (OCXO). Three

outputs are provided on the rear panel, which allows up to three T800 SL2 transmitters

to be referenced to the source oscillator.

Refer to M801-10.
