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 & 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 Series II
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).

2.2 Pozidriv & Philips Recess Head Screws
Pozidriv and Philips recess head screws will continue to be used in T800 Series II equip-
ment 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).

2.5 Chassis & Cover Compatibility
The chassis and covers used in T800 Series II modules incorporate a number of design
changes to improve Electro-Magnetic Compatibility (EMC) performance. It is impor-
tant that only the new-design covers are fitted to the new chassis to ensure correct
mechanical fit and continued compliance with appropriate EMC Type Approval regula-
tions.

Copyright TEL 01/04/00
3 Component Replacement
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 sol-
dering iron on the tip of the desoldering iron (this may require some addi-
tional 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.

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.

4.1 PGM800Win V1.0
PGM800Win V1.0 is different in concept from DOS versions of PGM800 in that it is Win-
dows1 based. It also includes many new and improved features over DOS versions of
PGM800.
The major changes are outlined below:
• The Windows environment makes data entry and editing significantly easier.
• PGM800Win includes several new radio models which are not programmable
with DOS versions of PGM800.
• Out of range frequencies will result in warning messages and will not be accepted
for entry into the standard library module. User defined modules can be created,
however, allowing variation from the standard library module.
• Channel numbers default to 0-127 to match the EPROM memory locations. How-
ever, the user can change this setting so that the channel numbers run from 1-128
to suit his/her particular needs.
Note: The data files produced by BASEPROG V1.0 and all DOS versions of
PGM800 are still compatible with PGM800Win V1.0.
4.2 PGM800Win V2.00
PGM800Win V2.00 is an upgraded and expanded version of PGM800Win V1.0. It has
been developed specifically for T800 Series II base stations, but retains the ability to pro-
gram Series I equipment.
The major changes are outlined below:
• PGM800Win V2.0 will program T800 Series II base station modules via serial com-
munications.
• Deviation and reference modulation settings are written automatically to the
radio.

1.1 Introduction
The T825 is a high performance microprocessor controlled FM base station receiver
designed for single or multichannel operation in the 66 to 88MHz frequency range1.
The receiver is a dual conversion superhet with a synthesised local oscillator. The first
IF is 10.7MHz, allowing exceptionally high spurious signal rejection to be achieved in
the receiver front end. The second IF section (455kHz) combines amplitude limiting,
detection and RSSI within a single integrated circuit. This IC also drives a noise level
detector for gating the audio output. RSSI can also be used to drive a carrier mute for
audio output gating (link selectable).
The audio section output can be adjusted to deliver >+10dBm to a 600 ohm balanced
output, 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 optional 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.
The T825 has a width of 60mm and occupies a single space in a Tait rack frame, which
has the ability to accommodate up to seven standard modules.
1. Although capable of operating over the 66-88MHz frequency range, the T825 has a
2MHz 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.)
Figure 2.2 T825 Front End, IF and Mute Block Diagram
The incoming signal from the N-type antenna socket is fed through a 7-pole, low pass
filter with a cut frequency of approximately 100MHz. This low loss filter (typically less
than 0.5dB insertion loss over 66-88MHz) provides excellent immunity to interference
from high frequency signals.
The signal is then further filtered, using a notched doublet (L410, L409) which provides
exceptional image rejection, before being amplified by approximately 12dB (Q400). The
signal is then passed through a further doublet (L403, L402) before being presented to
the mixer via an attenuator pad (1dB for narrow bandwidth, 0dB for wide bandwidth).
Each sub-block within the front end has been designed with 50 ohm terminations for
ease of testing and fault finding.

2.3 Mixer
(Refer to the front end circuit diagram (sheet 4) in Section 6 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 +22dBm (typical) and
this is fed to the mixer via a 4dB attenuator pad. A diplexer terminates the IF port of the
mixer in a good 50 ohms, thus preventing unnecessary intermodulation distortion.
2.4 IF Circuitry
(Refer to the IF section circuit diagram (sheet 3) in Section 6 and Figure 2.2.)
Losses in the mixer are made up for in a tuned, common gate, post mixer amplifier
(Q302). Several stages of amplification and filtering are employed in the IF circuitry.
The first crystal filter is a 4-pole device (&XF300 and &XF301) which is matched into 50
ohms on both its input and output ports. This stage is followed by a two-stage amplifier
(designed as a 50 ohm block) and second crystal filter (2 pole, &XF302), after which the
signal is mixed down to 455kHz with the second local oscillator (10.245MHz) by IC330.
The 455kHz signal is filtered using a six-pole ceramic filter (&XF304) before being lim-
ited and detected.
The second IF mixer, limiter, detector and RSSI is in a 16-pin IC (IC330). Quadrature
detection is employed, using L330, and the recovered audio on pin 9 of IC330 is typi-
cally 1.0V p-p for 60% system deviation.

2.5 Noise Mute (Squelch)
(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respec-
tively) in Section 6 and Figure 2.2.)
The noise mute operates on the detected noise outside the audio bandwidth. An opera-
tional amplifier in IC340 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,
operational amplifier (IC340), followed by another active band pass filter. The noise is
then rectified (D330) 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 introduced 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 sig-
nal at pin 1 of IC270 is used to disable the speaker and line audio outputs. The speaker
output can be separately enabled for test purposes by operating the front panel mute
disable 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 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.

2.7 Audio Processor
(Refer to the audio processor circuit diagram (sheet 2) in Section 6.)
Figure 2.3 T825 Audio Processor Block Diagram
The recovered audio on pin 9 of IC330 is passed through a frequency compensation net-
work and a third order elliptic active filter (IC210) to give the required response. Link-
ing (PL220 & 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 trans-
former to provide a balanced 2-wire or 4-wire, 600 ohm 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
Mute" switch (SW201) on the front panel opens the mute, allowing continuous monitor-
ing of the audio signal (on = audio muted; off = audio unmuted).
The mute control line is available on pads 234 and 231 ("RX GATE OUT") for control of
external circuitry. A high (9V) 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 & 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 pins 1 & 2 of PL270.
2.8 Power Supply And Regulators
(Refer to the regulators circuit diagram (sheet 6) in Section 6.)
Figure 2.4 T825 Power Supply And Regulators Block Diagram
The T825 is designed to operate off a 10.8-16V DC supply (13.8V nominal). A 5.3V regu-
lator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser circuitry.
It is also used as the reference for a DC amplifier (IC640, Q630 & 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
filter (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.)
Figure 2.5 T825 Microcontroller Block Diagram
Overall system control of the T825 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) & 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.

2.10 Synthesised Local Oscillator
(Refer to the synthesiser circuit diagram (sheet 7) in Section 6 and the VCO circuit dia-
gram in Part E.)
Figure 2.6 T825 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 (R510, C505) to attenuate
noise and other spurious signals. Note that the VCO frequency increases with increas-
ing control voltage.

2.11 VCO
(Refer to the VCO circuit diagram in Part E.)
The VCO transistor (Q1) operates in a common source 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-D6) to facilitate tuning within a 2MHz band of frequencies. A trimcap (&VC1-RX)
is used for coarse tuning of the VCO. The output from the oscillator circuit drives a cas-
code amplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage of
amplification, Q5. This is the final amplifier on the VCO PCB, and delivers +22dBm
(typically) to the receiver mixer input pad.
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 frequency required by the first mixer, i.e. there are no
multiplier stages.
The VCO frequency spans from 76.7-98.7MHz and is tuned to 10.7MHz above the
desired receive frequency (high side injection) to produce a 10.7MHz IF signal at the
output of the mixer.
2.12 Received Signal Strength Indicator (RSSI)
(Refer to the IF section circuit diagram (sheet 3) in Section 6.)
The RSSI provides a DC voltage proportional to the signal level at the receiver input and
is an on-chip function of IC330. RSSI level adjustment, temperature compensation and
buffering is provided by IC332 and IC333. The RSSI 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 at RV235.

3.1 Introduction
When you receive your T825 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
2MHz switching range (i.e. ±1MHz 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 2MHz 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 an IBM PC. You can also use
PGM800Win to select the receiver’s current operating frequency (or "default channel").
If the receiver is installed in a rack frame, you can program it via the programming port
in the speaker 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 the
rack frame backplane PCB. Refer to Part C in the T800 Series Ancillary
Equipment Service Manual (M800-00-101 or later issue) or 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
2MHz 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 (nearest the handle).
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 PL4-1 or the junction of L1 & R1 in the
VCO (this measures the synthesiser loop voltage).
•Single Channel Tune VCO trimmer &VC1-RX for a synthesiser loop volt-
age of 9V.
Multichannel Tune VCO trimmer &VC1-RX for a synthesiser loop volt-
age of 9V on the middle channel.
If there is no middle channel, tune &VC1-RX so that the
channels are symmetrically placed around a loop voltage
of 9V.
All channels should lie within the upper and lower limits
of 13V and 5V respectively.
Do not attempt to program channels with a greater fre-
quency separation than the specified switching range of
2MHz.
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 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.

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 & noise -55dB
• received CTCSS tone - tone and speech transmitted down 600 ohm line
+ speech to line output - audio bandwidth 10Hz to 3kHz
- hum & noise -45dB
• high pass filtered speech - 400Hz to 3kHz
+ internal CTCSS detection - hum & 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 600 ohm 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 PGM800Win software.
• Connect a high impedance voltmeter to PL4-1 or the junction of L1 & R1 in the
VCO (this measures the synthesiser loop voltage).
•Single Channel Tune VCO trimmer &VC1-RX for a synthesiser loop volt-
age of 9V.
Multichannel Tune VCO trimmer &VC1-RX for a synthesiser loop volt-
age of 9V on the middle channel.
If there is no middle channel, tune &VC1-RX so that the
channels are symmetrically placed around a loop voltage
of 9V.
All channels should lie within the upper and lower limits
of 13V and 5V respectively.
Do not attempt to program channels with a greater fre-
quency separation than the specified switching range of
2MHz.
• 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 1: In this and following sections deviation settings are given first for wide
bandwidth sets, followed by settings in brackets for narrow bandwidth sets
[ ].
Note 2: Before carrying out this alignment procedure, check that the solder links
in the receiver front end are set as described in the following table:

Set RV230 (front panel gating sensitivity) fully clockwise.
Inject a strong on-channel RF signal with ±3kHz deviation [±1.5kHz] at 1kHz into
the antenna socket and adjust front end doublets L410, L409, L403 & L402 to give
best sinad.
Continually decrease the RF level to maintain 12dB sinad.
Tune quad coil L330 for maximum audio level.
While maintaining a low level unmodulated RF input to the receiver, loosely cou-
ple into the first IF an additional high level signal at 10.7MHz - you will hear a
beat note.
Trim the synthesiser TCXO (=IC700) for zero beat.
Note: If a second oscillator is not available, you can connect a frequency counter to
IC710 pin 6 (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 4V p-p.
Readjust L410, L409, L403 & L402 to give best sinad.
Change the RF signal level to -70dBm and modulate with ±3kHz deviation
[±1.5kHz] at 1kHz.
Connect plugs PL210 and PL220 to give a flat audio response (refer to Section 3.5).
Adjust quad coil L330 and CV300 for minimum audio distortion.
Check that the distortion reading is:
wide bandwidth ≤2%
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% (both 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).

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 1.3 in this Part of the manual, and Figure 1.1 in Part
A shows typical labels). You can further verify the receiver 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 T825-10-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. 220-12345-00, 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.

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.
Parts List Amendments
At the front of the parts list is the Parts List Amendments box (an example of which is shown
below). This box contains a list of component changes which took place after the parts list and dia-
grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-
nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information
given in the parts list or diagrams. Components without circuit references are listed in IPN order.
The number in brackets at the end of each entry refers to the Tait internal Change Order document.

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 Series II products:
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 num-
bers 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).

T825 Parts List (IPN 220-01446-03)
How To Use This Parts List
The components listed in this parts list are divided into two main types: those with a circuit reference (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: the circuit reference, variant (if applicable), IPN and description. A number in the variant col-
umn indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by
an (S) at the start of the description column.
The miscellaneous and mechanical section lists the variant and common parts in IPN order. Where possible, a number in the legend
column indicates their position in the mechanical assembly drawing.
The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were
compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order
and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.

1.1 Introduction
The T826 is a synthesised, microprocessor controlled FM base station transmitter
designed for single or multichannel operation in the 66 to 88MHz frequency range1 with
a standard power output of 25W. The RF section of the transmitter comprises a fre-
quency synthesiser which provides 125mW of frequency modulated RF drive to a two
stage, wide band output driver followed by a 25W power amplifier. A thermal shut-
down feature is provided in the T826 in case operating temperatures exceed acceptable
levels.
The T827 is a synthesised, microprocessor controlled FM base station exciter designed
for single or multichannel operation in the 66 to 88MHz frequency range1. With a stand-
ard power output of only 1W, the exciter is designed for use with the T828 50W power
amplifier. The RF section of the exciter comprises a frequency synthesiser which pro-
vides 125mW of frequency modulated RF drive to a two stage, wide band output ampli-
fier.
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 both sides of the main circuit board is obtained by removing
each of the chassis lids. There is provision within the chassis 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.
The T826 and T827 are both 60mm wide and each occupies a single space in a Tait rack
frame, which has the ability to accommodate up to seven standard modules.
1. Although capable of operating over the 66-88MHz frequency range, the T826 and T827
have an 8MHz switching range (see Section 1.2.3 and Section 3.1).

2.2 Microcontroller
(Refer to the microcontroller circuit diagram (sheet 8) in Section 6.2 or 6.3.)
Figure 2.3 T826/827 Microcontroller Block Diagram
Overall system control of the T826/827 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) & D-range 2;
• monitor channel change inputs from D-range 2;
• generate timing waveforms for CTCSS encoding;
• coordinate and implement timing control of the exciter/transmitter;
• control the front panel "Supply" LED.

2.3 Synthesised Local Oscillator
(Refer to the synthesiser circuit diagram (sheet 7) in Section 6.2 or 6.3 and the VCO cir-
cuit diagram in Part E.)
Figure 2.4 T826/827 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 5 & 6) 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 & 8, Q710, Q720). This produces a
ramping waveform which is centred around a DC level determined by the incoming
audio. IC720 pins 5 & 6 perform as a comparator, ultimately producing a phase-modu-
lated 200kHz square wave. This is followed by another phase shifting stage (IC720 pins
3 & 4, Q730, Q740), before being divided down to 6.25kHz or 5kHz within the synthe-
siser 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 & 7) which produces a
DC voltage between 0V and 20V to tune the VCO. This VCO control line is further fil-
tered 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 & 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.

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 2.5 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
synthesiser 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 2.5.
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 source 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 pin 7) is applied to the vari-
caps (D1-D6) to facilitate tuning within an 8MHz band of frequencies. A trimcap
(&VC1-TX) 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 amplification, Q5. This is the final amplifier on the VCO PCB, and delivers
+21dBm (typically) to the exciter drive amplifier.
A low level "sniff" is taken from the output of Q3 and used to drive the divider buffer
(Q795) for the synthesiser (IC740).
The VCO operates at the actual output frequency of the exciter, i.e. there are no multi-
plier stages. The VCO 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 (Q1) and buffer amplifier (Q2 & Q3) are supplied from one +9V switched sup-
ply by Q540 via the capacitor multiplier (Q550, C550).
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.

2.5 Audio Processor
(Refer to the audio processor circuit diagram (sheet 2) in Section 6.2 or 6.3.)
Figure 2.6 T826/827 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 600 ohm balanced (or unbalanced) line, and
the other from a local microphone. The microphone signal is passed first to a pre-ampli-
fier (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 con-
nected to the multiplexer and is disabled by the microphone PTT switch.
A third input for external CTCSS tones is also provided.

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 reservoir capacitor (C233) which controls the attenuator (Q230, Q220), thus complet-
ing 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 there-
fore be avoided where possible.
2.5.5 Outputs To Modulators
The output signal from the limiter (IC210, IC230) is added with a CTCSS tone at a sum-
ming amplifier (IC260). The signal is then low pass filtered (IC260) and split to supply
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.

2.6 Power Supply & Regulator Circuits
(Refer to the regulators circuit diagram (sheet 6) in Section 6.2 or 6.3.)
Figure 2.7 T826/827 Power Supply & Regulators Block Diagram
The T826 and T827 are designed to operate from a 10.8-16V DC supply (13.8V nominal).
A 5.3V regulator (IC630) runs directly from the 13.8V rail, driving much of the synthe-
siser circuitry. It is also used as the reference for a DC amplifier (IC640, Q630, Q620)
which provides a medium current capability 9V supply.
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, and the Lock-Detect amplifiers.
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.

2.8 T826 Drive Amplifier & PA
(Refer to Figure 2.1 and the exciter and PA circuit diagrams (sheets 3 & 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 (Q307, Q312). The forward and
reverse RF power levels are sensed via a dual directional coupler and detector diodes
(D440, D441 in the PA cavity). The detected DC signals are summed with the "power
set" level and fed to the control integrator (IC310 pins 1, 2 & 3). The output control volt-
age is buffered by Q309 and Q315, and applied to the collectors of the wide band exciter
amplifiers.
Note: Forward and reflected power signals are summed so that, under high
VSWR, the power control will turn the output RF level down.
The maximum output power of the transmitter is limited by a voltage clamp circuit
(consisting of a potential divider formed by R369//R374 and R375//R359//R360) which
turns on Q308, clamping the control voltage to approximately 7.8V. When the maxi-
mum operating temperature is exceeded, the clamp voltage is reduced to approximately
5.7V by removing R359//R360 from the circuit (see below).
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. The RF input signal is switched by a PIN
switch attenuator (D300, D301, D302).
Cyclic keying control is provided by additional circuitry consisting of several time
delay, ramp and gate stages:
• Q305, IC310 power ramping
• Q304, Q305 Tx-Reg. and Lock-Detect gate
• Q300, Q301, Q302 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 550mW (+27.5dBm) for an
input of 65mW (+18dBm) when the power control is set to maximum.
Note: The VCO output level of 125mW (+21dBm) is attenuated by a 3dB attenua-
tor (R517, R518 & R519) in the VCO cavity. This provides good VCO/exciter
isolation as well as the correct exciter drive level.
A temperature sensor (R480) is provided so that the RF output power can be reduced to
a preset level when a set temperature is exceeded. This is a protection circuit (IC310
pins 5, 6 & 7, Q311) to prevent overheating, as the unit is not rated for continuous oper-
ation at high temperatures (refer to Section 1.2.3 for duty cycle specifications). RV302
sets the PA output power while under high temperature fold-back conditions.
The output of the temperature-sense comparator (IC310 pin 7) also feeds to a secondary
shutdown clamp circuit (Q303, Q360, Q308). The clamp voltage is set to approximately
![](/img.php?id=111477&img=bg65.png)
M820-00 T826/827 Circuit Operation C2.13
Copyright TEL 01/04/00
5.7V by the potential divider R369//R374 and R375 when the maximum operating tem-
perature is exceeded. This ensures that the temperature shutdown will reduce the out-
put power even if the power control circuit is in an open loop condition.
The attenuator (R410, R411 & R412) aids in reducing exciter/PA interaction while also
ensuring a reasonable match for Q312.
The RF output from the exciter is fed to the driver stage (Q415) and then to the final
(Q425). The DC supply is fed to the final via a low pass filter with special low frequency
decoupling.
The directional coupler provides the required feedback for the power control loop while
the harmonics are attenuated by the low pass filter.
2.9 T827 Exciter Drive Amplifier
(Refer to Figure 2.2 and the exciter circuit diagram (sheet 3) in Section 6.3.)
A two-stage, wide band amplifier (Q320, Q321) provides an output level of approxi-
mately 1W (+30dBm) for an input of 125mW (+21dBm) from the VCO. IC300 pins 5, 6 &
7, Q301 and Q302 provide a 10.5V regulated supply for the exciter.
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 exciter control circuit and to switch off the
RF signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator
(D320, D321, D322).
Cyclic keying control is provided by additional circuitry consisting of several time
delay, ramp and gate stages:
• Q300, IC300 pins 5, 6 & 7 power ramping
• Q380, Q381 Tx-Reg. and Lock-Detect gate
• Q365, Q366, Q367, Q368 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.
R517, R518 and R519 form a 3dB attenuator to provide good VCO/drive amplifier isola-
tion.
The output attenuator (R337, R338, R339) assists in reducing exciter/PA interaction
while also ensuring a good match for Q321.
Note: The exciter provides a DC control signal to the PA via the RF coax. This is
injected via %L382.

3.1 Introduction
When you receive your T826 transmitter or T827 exciter 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 fre-
quency), you should only need to reprogram the transmitter/exciter 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/exciter 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/exciter’s EEPROM
memory (IC820) by using the PGM800Win software package and an IBM PC. You can
also use PGM800Win to select the transmitter/exciter’s current operating frequency (or
"default channel").
If the transmitter/exciter is installed in a rack frame, you can program it via the pro-
gramming port in the speaker panel. However, you can also program the transmitter/
exciter 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/
exciter 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 the
rack frame backplane PCB. Refer to Part C in the T800 Series Ancillary
Equipment Service Manual (M800-00-101 or later issue) or 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 T826/827 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 (nearest the handle).
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 PL4-1 or the junction of L1 & R1 in the
VCO (this measures the synthesiser loop voltage).
• Key the transmitter by earthing the Tx-Key line.
•Single Channel Tune VCO trimmer &VC1-TX for a synthesiser loop volt-
age of 9V.
Multichannel Tune VCO trimmer &VC1-TX for a synthesiser loop volt-
age of 9V on the middle channel.
If there is no middle channel, tune &VC1-TX so that the
channels are symmetrically placed around a loop voltage
of 9V.
All channels should lie within the upper and lower limits
of 13V and 5V 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 (T826 Only)
Connect an RF power meter with suitable attenuation to the output socket and
key the transmitter.
Adjust RV301 for the required output power (between 5 and 25W).

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 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 1-4 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 1-4 below on the middle channel
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 450Hz 1.5V rms (+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 [±1.5kHz] deviation
at 450Hz.
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
[±1.5kHz] deviation (you can use either the mouse or up and down arrow keys).
4. Change the input frequency back to 450Hz.
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 65 to 260Hz.
1. Use the “EDIT FILL” button on the tool bar or go to “Edit”, “Fill”, “Epot Settings” on
the menu bar.

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 T826/827 with the front panel "Carrier" switch.
Adjust RV805 (CTCSS level adjust) to give ±500Hz [±250Hz] deviation.
Set the maximum deviation as per Section 3.4.6.
3.4.6 FM Deviation (Limiter) Adjustment
Note: If the T826/827 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 frequencies 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 & 4; pins 2 & 3
shorted).
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
setting for the current channel to obtain a deviation limit of ±4.7kHz [±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 [±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 [±1.5kHz] deviation.
Reapply the CTCSS signal (if required).

3.9 Audio Processor & CTCSS
3.9.1 Two Point Modulation
The T826 and T827 utilise 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 fre-
quency. 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 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 1-4 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 1-4 below on the middle channel
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 450Hz 1.5V rms (+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 [±1.5kHz] deviation
at 450Hz.
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
[±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

4. Change the input frequency back to 450Hz.
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 65 to 260Hz.
3.9.3 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 T826/827 with the front panel "Carrier" switch.
Adjust RV805 (CTCSS level adjust) to give ±500Hz [±250Hz] deviation.
Set the maximum deviation as per Section 3.9.4.
3.9.4 Limiter Adjustment
Note: If the T826/827 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 frequencies 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.
Set the links in the audio processor section as required (refer to Section 3.5).
Inject 1kHz at -10dBm into the line input (D-range 1 (PL100) pins 1 & 4; and pins 2
& 3 shorted).
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
setting for the current channel to obtain a deviation limit of ±4.7kHz [±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 [±2.3kHz]. Readjust “Deviation” if necessary
via PGM800Win.

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.
Remove the CTCSS signal (if used).
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 [±1.5kHz] deviation.
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
Set RV210 (line sensitivity) fully clockwise and key the transmitter by earthing the
Tx-Key line.
Reduce the line level to -50dBm at 1kHz and set RV220 (compression level) fully
clockwise.
Check that ±3kHz [±1.5kHz] deviation is still available.
Slowly increase the audio input level until the demodulated waveform shows sig-
nificant signs of clipping (approximately ±4.5kHz [±2.3kHz] deviation).
Adjust RV220 anticlockwise until the demodulated waveform is just clipping
(approximately ±4kHz [±2kHz] deviation).
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
Key the transmitter by earthing the Tx-Key line and plug a microphone jack into
the front panel socket.
Adjust RV220 (compression level) fully clockwise.
Acoustically couple the microphone to a tone box (1kHz) and close the PTT
switch.

Increase the audio level until the demodulated waveform shows significant signs
of clipping (approximately ±4.5kHz [±2.3kHz] deviation).
Adjust RV220 anticlockwise until the demodulated waveform is just clipping
(approximately ±4kHz [±2kHz] deviation).
Increase the audio level by 10dB and verify that the test tone is held just into clip-
ping.
Whistle steadily into the microphone, checking that approximately ±4kHz
[±2kHz] deviation is produced. The modulated waveform should be basically
sinusoidal.
Speak into the microphone, checking that the modulation peaks reach about
±5kHz [±2.5kHz] deviation.
As the line is to be used without compression, set RV210 (line sensitivity) as

6.1 Introduction
Product Type Identification
You can identify the transmitter or exciter type by checking the product code printed on a label on
the rear of the chassis (product codes are explained in Section 1.3 in this Part of the manual, and Fig-
ure 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
T826-10-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 or exciter.
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

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.
Parts List Amendments
At the front of the parts list is the Parts List Amendments box (an example of which is shown
below). This box contains a list of component changes which took place after the parts list and dia-
grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-
nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information
given in the parts list or diagrams. Components without circuit references are listed in IPN order.
The number in brackets at the end of each entry refers to the Tait internal Change Order document.

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 Series II products:
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 num-
bers 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).

T826 Parts List (IPN 220-01443-04)
How To Use This Parts List
The components listed in this parts list are divided into two main types: those with a circuit reference (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: the circuit reference, variant (if applicable), IPN and description. A number in the variant col-
umn indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by
an (S) at the start of the description column.
The miscellaneous and mechanical section lists the variant and common parts in IPN order. Where possible, a number in the legend
column indicates their position in the mechanical assembly drawing.
The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were
compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order
and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.

Note: %D205 and %D210 are optional level limiting diodes for
special applications.
=R705 (47 ohm) and =SK710 are fitted in place of
=IC700 when an external frequency reference is used.
These two components are supplied with the auxiliary
D-range kits (T800-06-0000 & T800-06-0001).

T827 Parts List (IPN 220-01447-04)
How To Use This Parts List
The components listed in this parts list are divided into two main types: those with a circuit reference (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: the circuit reference, variant (if applicable), IPN and description. A number in the variant col-
umn indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by
an (S) at the start of the description column.
The miscellaneous and mechanical section lists the variant and common parts in IPN order. Where possible, a number in the legend
column indicates their position in the mechanical assembly drawing.
The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were
compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order
and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.
Parts List Amendments
There were no amendments to the parts list at the time of publication.

Note: %D205 and %D210 are optional level limiting diodes for
special applications.
=R705 (47 ohm) and =SK710 are fitted in place of
=IC700 when an external frequency reference is used.
These two components are supplied with the auxiliary
D-range kits (T800-06-0000 & T800-06-0001).

1.1 Introduction
The T828 is an FM base station power amplifier designed for single or multichannel
operation within the frequency range 66 to 88MHz. The output power capability is 10
to 60W.
The PA comprises a broad band, two stage drive amplifier whose output is split to drive
two separate output stages. The outputs from these final stages are then recombined
and filtered before being fed to the output socket. This type of balanced output stage
offers two advantages over single ended types:
• improved intermodulation performance in the presence of high signal levels
from adjacent transmitters;
• enhanced reliability: if one of the two output stages fails, the transmitter can
still produce one quarter of its rated power.
VSWR and thermal protection are incorporated into the basic design, while monitoring
and alarm signals are available for both forward and reverse power. The output power
is adjustable from the front panel.
The circuitry is built on a single PCB which is mounted directly on a die-cast chassis/
heatsink. Extensive use is made of surface mount technology.
The T828 has a width of 60mm and occupies a single space in a Tait rack frame, which
has the ability to accommodate up to seven standard modules.

2.2 RF Circuitry
(Refer to the RF section circuit diagram in Section 5.)
Figure 2.2 T828 RF Circuitry Block Diagram
The driver stage of the T828 consists of a two-stage transistor amplifier (Q1, Q2) which
delivers 20W. This signal is split via a hybrid Wilkinson splitter (L220, L221) and used
to drive the two final amplifiers (Q3, Q4). The outputs from the finals are combined
with a hybrid Wilkinson combiner (L250, L251) and passed to the antenna socket via a
directional coupler and a low pass filter.
The directional coupler senses forward and reflected power, which is rectified (D201,
D200) and passed to the control circuitry for metering, alarm and power control pur-
poses.
Power control is via a series pass transistor (Q16), which controls the supply voltage on
the collector of the driver transistor (Q1).

2.3 Control Circuitry
(Refer to the control section circuit diagram in Section 5.)
Figure 2.3 T828 Control Circuitry Block Diagram
2.3.1 Power Control
The DC voltages from the directional coupler representing forward and reflected power
are buffered by the voltage followers IC3b and IC3a respectively. Their outputs are
summed at an integrator (IC1c), which drives the series pass control element (Q16).
Forward and reflected power are summed so that, under high output VSWR, the power
control turns the PA down. This is because the control loop adjusts for the same DC
voltage from the directional coupler that would have been present if there were no
reflected power.

2.3.2 Thermal Protection
At excessively high temperatures, the output power will automatically reduce to a pre-
set level, thus preventing the PA from overheating.
A thermistor controlled voltage divider (R68, R300) applies a voltage to a comparator
with hysteresis (IC1d). The threshold of the comparator is independently set by RV69.
This sets the shutdown temperature.
The output from the comparator and driver Q14 is summed into the power control net-
work via RV74 so that the power level to which the PA must turn down may be set.
2.3.3 Forward And Reverse Power Alarms
If forward power drops below, or reverse power rises above, presettable limits, alarms
may be triggered.
The alarm outputs are open drain configuration and are low under normal conditions
(i.e. forward and reverse power levels are normal).
IC1a and IC1b form comparators with thresholds adjusted via RV48 (forward power)
and RV52 (reverse power) respectively. The inputs are from the forward and reverse
power signals from the directional coupler, buffered by IC3b and IC3a. Thus, the power
levels at which the forward and reverse power alarms are triggered are defined by RV48
and RV52 respectively.
2.3.4 Forward And Reverse Power Metering
Forward and reverse power signals from buffers IC3b and IC3a are available for meter-
ing purposes. The output currents are adjustable via RV43 (forward power) and RV57
(reverse power).

3.2 Optimising Intermodulation Performance
Note: If the T828 is to be used in countries where intermodulation performance is
a Type Approval requirement (e.g. Europe, UK), or if intermodulation per-
formance is of particular concern, the two 50 ohm Teflon coax phasing
sections provided must be fitted.
3.2.1 Trimming
The Teflon phasing sections supplied are cut for 66MHz. If the required operating
frequency is greater than 66MHz, you must trim both sections to the correct
length according to the following formula:
length of centre conductor (cm) =
Note: If the T828 is to be used over a band of frequencies, trim both sections for the
centre operating frequency.
Trim the ends of the Teflon coax as shown in Figure 3.2 (dimensions shown in
mm).
Figure 3.2 T828 Phasing Section Trimming Detail
3.2.2 Fitting
Note: If the Teflon phasing sections have been unbound for trimming, they must
be rebound in the same way as the original components.
Remove the wire links fitted in locations TL1 and TL2 (refer to Figure 3.3).
Fit the Teflon phasing sections as shown in Figure 3.3 and solder the terminations
as shown in Figure 3.4.

3.3 Preliminary Checks
Check for short circuits between the positive rail and earth.
Set up the test equipment as in Figure 3.1.
Connect the T828 to a 13.8V DC supply.
Check that the quiescent current is approximately 45mA.
To key the transmitter, earth the key line (D-range 1 pin 13) on the exciter.
Check that the power supply is still at 13.8V under load.
Check that the regulated power control supply is approximately 7V.
Note: The output power and alarm levels should be set with the cover shield on.
If the cover is removed for other adjustment procedures, make a final check
of the output power and alarm levels with the cover shield on.
3.4 Setting The Output Power
Caution: If the temperature shutdown power level has not yet been set or is
unknown, check that the unit does not overheat while setting the out-
put power.
Note 1: Cables and connectors can easily cause a power loss of several watts if either
too long or poorly terminated. Always use the shortest possible lead
between the T828 and power meter.
Note 2: You will need appropriate extension leads if you wish to carry out the
adjustment procedures with the T828 withdrawn from the rack in the
latched position. Alternatively, disconnect and withdraw the T828 and
reconnect it behind the rack.
Note 3: The actual power used may be limited by regulatory requirements.
Connect the exciter output to the PA input via a thru-line wattmeter with a 5W
full scale reading. Special SMC/BNC leads will be required.
Connect an RF power meter to the PA output. Set the front panel power control
preset (RV63) fully clockwise.
Key on the drive source.
Check that the power output exceeds 60W.
Adjust RV63 to reduce the power output to the required level (e.g. 50W).

3.5 High Temperature Shutdown Power Level
Note: The temperature shutdown circuit is factory set to approximately 130°C and
20W. RV69 and RV74 should not be readjusted if normal operation is
required.
Power up the T828 and adjust the power control pot. (RV63) for the normal oper-
ating power level.
Turn the temperature set pot. (RV69) fully anticlockwise to avoid RF power
cycling between the levels set by RV63 and RV74.
Apply heat to the NTC (R300) with the tip of a soldering iron.
Adjust the shutdown power level pot. (RV74) to the desired level. For continuous
operation during fault conditions, set the shutdown power in the range 10 to 20W.
For normal operation, i.e. shutdown under extreme PA internal temperatures
(approx. 130°C) or excessive dissipation in the splitter balance resistor (R220),
adjust the temperature set pot. (RV69) for a voltage reading of 150mV at TP1 (pin
12 of the LM324D [IC1]).
3.6 Remote Forward Power Meter Calibration
If a remote meter is connected, adjust the forward power meter calibration control
(RV43) for the remote reading to agree with the RF power meter reading.
3.7 Remote Reverse Power Meter Calibration
If a remote meter is connected, connect a 50 ohm 3dB pad (with the output open
circuit) to the PA output.
Apply RF drive and Tx key.
Adjust the reverse power meter calibration control (RV57) for a quarter of the for-
ward power reading.

3.8 Setting Alarm Levels
Note: If forward and reverse power metering is being used, set up their calibration
(Section 3.6 and Section 3.7) before setting the alarm levels.
3.8.1 Forward Power
Power up the T828 and adjust the front panel power control (RV63) so that the
output power is at the alarm level required (e.g. 40W if the PA normally operates
at 50W).
Adjust the forward power alarm set control (RV48) so that the forward power
alarm LED lights.
Check the alarm level setting by adjusting the power up and down and observing
the alarm LED. A few watts hysteresis can be expected.
Readjust RV63 for the normal operating level.
Note: Remote indication is available at D-range pin 3.
3.8.2 Reverse Power
Power up the T828 and adjust the front panel power control (RV63) for the normal
operating power level.
Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the
reverse power alarm set control (RV52) so that the reverse power alarm LED
lights.
Example: A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad
(100W) to the PA output. This will result in a return loss of 6dB.
Note: Remote indication is available at D-range pin 4.

4 T828 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 infor-
mation 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 Customer Support, Radio Systems Division, Tait
Electronics Ltd, Christchurch, New Zealand (full contact details are on page 2).
Refer to Section 5 where the parts lists, grid reference index and diagrams will provide
detailed information on identifying and locating components.

4.1 Visual Checks
Remove the side cover from the T828 and inspect the PCB for damaged or broken
components, paying particular attention to the surface mounted devices (SMDs).
Also check for defective solder joints.
Refer to Section 4.7, Section 4.8 and Section 3 of Part A for more details on repair
and replacement of components.
4.2 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 20k ohm/V or bet-
ter 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.
4.3 DC Checks
Note: No RF power is to be applied during these checks.
Check that +13.8V is present on the collectors of Q1, Q2, Q3 and Q4. Make this
measurement when the transmitter is not keyed.
Check that +13.8V is present at pin 4 of IC1 and pin 8 of IC3.
Check that 7.0V is present at the output of regulator IC2.

4.4 RF Checks
4.4.1 General
You can measure in-circuit RF levels around Q1 and Q2 with an RF probe on which the
earth lead has been shortened to a minimum (i.e. 13mm); refer to the PA Fault Finding
Chart (Section 4.6.1). You must measure all other stages with a power meter at the 50Ω
points in the circuit.
For problems with the power control circuitry, refer to the Power Control Fault Finding
Chart (Section 4.6.2).
4.4.2 PA Faults
If a PA fault has occurred, or is suspected, it is easier to find if the various stages are iso-
lated by use of the test breaks (refer to Figure 4.1) and each stage analysed individually.
Eight 50 ohm test break points have been included throughout the RF circuitry to enable
individual transistor stages to be tested.
Testing may be performed by removing the solder short across the test break and sol-
dering a 50 ohm test lead to the appropriate signal and earth pads.
Note 1: Use good quality 50Ω coax for the "flying" test leads.
Note 2: Ensure each output is terminated in a 50Ω load of the correct power rating.

4.7 Replacing RF Power Transistors
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, note the location of any other components that will also
need to be removed. Replacing each component in its original location
will help to maintain the performance of the PA.
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 PA.
Desolder and remove the components from around the transistor.
Desolder the transistor tabs by heating with a soldering iron and lifting away
from the PCB with a screwdriver or thin stainless steel spike. Unscrew the transis-
tor 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.
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.
Lightly solder one tab to the PCB, then torque down the retaining nut to the cor-
rect torque (0.7Nm/6in.lbf.).
Caution: Do not solder all the tabs before torquing down otherwise the device
may be broken.
Solder all transistor tabs to the PCB.
Replace each component in exactly the same position as noted previously.

4.8 Removing The PCB From The Heatsink
Note: This is a lengthy procedure and should be considered only after all other
checks have been carried out. There are no components on the bottom of the
PCB.
Remove the harmonic filter shield lid.
Remove the 50 ohm output N-type connector by unscrewing it from the heatsink
casting and desoldering it from the PCB.
Unplug the 50 ohm input coaxial cable from the PCB, unscrew the BNC connector
from the heatsink, and remove the connector and cable (cutting cable ties as
required).
Desolder the positive and negative power feed wires from the PCB.
Desolder the alarm and metering wires from the PCB.
Remove the 2 screws securing the D-range connector and PCB to the heatsink and
withdraw the assembly and wires from the heatsink (cutting cable ties as
required).
Remove the transistor stud nuts.
Remove the mounting screws for the TO-220 devices: R230, R231 and Q16.
Remove the 10 PCB retaining screws.
Push the three LEDs out of their front panel grommets.
Lift the PCB gently from the heatsink to gain access to the underside of the board.
Note: R230/231 and Q1-Q4 may be stuck down with heatsink compound. You
may need to carefully prise them away from the heatsink with a small
screwdriver.
Caution: Keep the heatsink compound clean while the PCB is detached. Any
objects caught in the heatsink compound underneath the device which
prevent effective earthing and/or heatsinking may cause the device to
fail.
Caution: Do not operate the PA with the PCB detached as the heatsink is used
for earthing and heat dissipation.
To replace the PCB, reverse the order of removal, taking care that the wiring is cor-
rectly positioned and not 'pinched'.
Q1-Q4: Torque down the retaining nut to the correct torque (0.7Nm/
6in.lbf.).

Make sure that the heatsink compound has stayed clean, and that the insulating
pad for Q16 is not damaged.
If you have difficulty refitting the LEDs, try pushing the body of the LED back
into the grommet with a thin screwdriver or spike.

5.1 Introduction
Product Type Identification
You can identify the PA type by checking the product code printed on a label on the rear of the chas-
sis/heatsink (product codes are explained in Section 1.3 in this Part of the manual, and Figure 1.1 in
Part A shows typical labels).
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.
Parts List Amendments
At the front of the parts list is the Parts List Amendments box (an example of which is shown
below). This box contains a list of component changes which took place after the parts list and dia-
grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-
nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information
given in the parts list or diagrams. Components without circuit references are listed in IPN order.
The number in brackets at the end of each entry refers to the Tait internal Change Order document.

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).
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 num-
bers 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).

1Introduction
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.

Parts List Amendments
At the front of the parts list is the Parts List Amendments box (an example of which is shown
below). This box contains a list of component changes which took place after the parts list and dia-
grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-
nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information
given in the parts list or diagrams. Components without circuit references are listed in IPN order.
The number in brackets at the end of each entry refers to the Tait internal Change Order document.
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).

T820 VCO Parts List (IPN 220-01180-05)
How To Use This Parts List
The components listed in this parts list are divided into two main types: those with a circuit reference (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: the circuit reference, variant (if applicable), IPN and description. A letter in the variant column
indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by an (S)
at the start of the description column.
The mechanical and miscellaneous section lists the variant and common parts in IPN order.
The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were
compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order
and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.
Parts List Amendments
There were no amendments to the parts list at the time of publication.
