Format
We have published this manual in a ring binder so that "revision
packages" containing additional information pertaining to new
issues of PCBs can be added as required.
Revision Packages
Revision packages will normally be published to coincide with
the release of information on a new PCB, and may also contain
additions or corrections pertaining to other parts of the manual.
You may order as many packages as you require from your local
Tait Dealer or Customer Service Organisation. Revision packages are supplied ready-punched for inclusion in your manual.
Revision Control
Each page in this manual has a date of issue. This is to comply
with various Quality Standards, but will also serve to identify
which pages have been updated and when. Each page and its
publication date is listed in the "List of Effective Pages", and a
new list containing any new/revised pages and their publication dates will be sent with each revision package.
Any portion of text that has been changed is marked by a vertical line (as shown at left) in the outer margin of the page or column. Where the removal of an entire paragraph means there is
no text left to mark, an arrow (as shown at left) will appear in
the outer margin. The number beside the arrow will indicate
how many paragraphs have been deleted. Changes to diagrams
that cannot be marked by these methods will be explained in an
Amendments Box added to the diagram.
The manual issue and revision status are indicated by the last
three digits of the manual product code. These digits start at 200
and will increment through 201, 202, 203, etc., as revision packages are published, e.g:
2 0 3
issue status
Copyright TEL
revision status
23/07/99
4
M830-00
Thus, issue 203 indicates the third revision to issue 2 and means
that three packages should have been added to the manual. The
issue digit will only change if there is a major product revision,
or if the number of revision packages to be included means that
the manual becomes difficult to use, at which point a new issue
manual will be published in a new ring binder.
PCB Information
PCB information is provided for all current issue PCBs, as well
as all previous issue PCBs manufactured in production quantities, and is grouped according to PCB. Thus, you will find the
parts list, grid reference index (if necessary), PCB layouts and
circuit diagram(s) for each individual PCB grouped together.
Errors
If you find an error in this manual, or have a suggestion on how
it might be improved, please do not hesitate to contact Customer
Support, Radio Systems Division, Tait Electronics Ltd, Christchurch, New Zealand (full contact details are on page 2).
Updating Equipment And Manuals
In the interests of improving performance, reliability or servicing, Tait Electronics Ltd
reserve the right to update their equipment and/or manuals without prior notice.

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 substance, 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.

Torx Recess Head Screws
A2.1
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 applications.
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 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
M830-00
Pozidriv and Philips recess head screws will continue to be used in T800 Series II equipment in a few special applications. It is important that you use the correct type and size
screwdriver for each screw type to avoid damaging the screw head.
It is particularly important that you do not use Philips screwdrivers on Pozidriv screw
heads as the tapered driving flutes of the Philips screwdriver do not engage correctly
with the parallel-sided slots in the Pozidriv screw head. This can result in considerable
damage to the screw head if the screwdriver tip turns inside the recess.
Note:
If you find you need excessive downwards pressure to keep the screwdriver
tip in the Pozidriv screw head, you are probably using the wrong type and/
or size screwdriver.
Figure 2.2 below shows the main differences between typical Pozidriv and Philips screw
heads and screwdriver tips (actual hardware may differ slightly from these illustrations
due to variations in manufacturing techniques).

i.e. the one adjacent to the front panel handle and on the opposite side to the main
D-range connector (D-range 1/PL100).
You need to remove the bottom cover to:
• access transmitter RF power transistors and many SMD components
• change solder blob links
• fit test leads to circuit block access points.

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 important 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 regulations.
Figure 2.3 below shows some of the main features which can be used to identify the
new-design chassis and covers.

Component Replacement
3.1
Leaded Components
A3.1
Whenever you are doing any work on the PCB that involves removing or fitting components, you must take care not to damage the copper tracks. The two satisfactory methods 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 circular motion.
Start the suction and continue the movement until 3 or 4 circles have been completed.
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 soldering iron on the tip of the desoldering iron (this may require some additional help).
3.1.2
Component Cutting Method
Cut the leads on the component side of the PCB.
Heat the solder joint sufficiently to allow easy removal of the lead by drawing it
out from the component side: do not use undue force.
Fill the hole with solder and then clear with solderwick.

Surface Mount Devices
Caution:
3.3
M830-00
Surface mount devices (SMDs) require special storage, handling,
removal and replacement techniques. This equipment should be serviced only by an approved Tait Dealer or Customer Service Organisation equipped with the necessary facilities. Repairs attempted with
incorrect equipment or by untrained personnel may result in permanent damage. If in doubt, contact your nearest Tait Dealer or Customer
Service Organisation.
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 equivalent.

PGM800Win Version 2.00
PGM800Win V1.0
PGM800Win V1.0 is different in concept from DOS versions of PGM800 in that it is Windows1 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. However, 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 program Series I equipment.
The major changes are outlined below:
•
PGM800Win V2.0 will program T800 Series II base station modules via serial communications.
•
Deviation and reference modulation settings are written automatically to the
radio.

designed for single or multichannel operation in the 136 to 174MHz frequency range1.
The receiver is a dual conversion superhet with a synthesised local oscillator. The first
IF is 21.4MHz, 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 T835 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 136-174MHz frequency range, the T835 has a
3MHz switching range (see Section 1.2.3 and Section 3.1).

The incoming signal from the N-type antenna socket is fed through a 7-pole, low pass
filter with a cut frequency of approximately 200MHz. This low loss filter (typically less
than 0.5dB insertion loss over 136-174MHz) provides excellent immunity to interference
from high frequency signals.
The signal is then further filtered, using a notched doublet (L410, L420) which provides
exceptional image rejection, before being amplified by approximately 12dB (Q420). The
signal is then passed through a further doublet (L460, L470) before being presented to
the mixer.
Each sub-block within the front end has been designed with 50 ohm terminations for
ease of testing and fault finding.

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 (nominal). The voltage controlled oscillator (VCO) generates a level of +22dBm (typical) and
this is fed to the mixer via a 2dB 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
(Q310). Several stages of amplification and filtering are employed in the IF circuitry.
The first crystal filter is a 4-pole device (&XF310 and &XF320) 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, &XF330), after which the
signal is mixed down to 455kHz with the second local oscillator (20.945MHz) by IC340.
The 455kHz signal is filtered using a six-pole ceramic filter (&XF340) before being limited and detected.
The second IF mixer, limiter, detector and RSSI is in a 16-pin IC (IC350). Quadrature
detection is employed, using L360, and the recovered audio on pin 7 of IC350 is typically 0.3V p-p for 60% system deviation.

Noise Mute (Squelch)
M830-00
(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respectively) in Section 6 and Figure 2.2.)
The noise mute operates on the detected noise outside the audio bandwidth. An operational amplifier in IC390 is used as an active band pass filter centred on 70kHz to filter
out audio components. The noise spectrum is then further amplified in a variable gain,
two-stage amplifier (Q340 & Q350) with additional filtering. The noise is then rectified
(D310) and filtered to produce a DC voltage proportional to the noise amplitude. The
lowest average DC voltage corresponds to a high RF signal strength and the highest DC
voltage corresponds to no signal at the RF input.
The rectified noise voltage is compared with a threshold voltage set up on RV230, the
front panel "Gating Sensitivity" potentiometer. Hysteresis is 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 signal at pin 7 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 respectively) in Section 6 and Figure 2.2.)
A high level carrier mute facility is also available. The RSSI (refer to Section 2.12) provides 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.

The recovered audio on pin 7 of IC350 is processed by IC390 and passed through a frequency compensation network and a third order elliptic active filter (IC210) to give the
required response. Linking (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 conditions the inputs of these amplifiers are shunted to ground via transistors Q230 and Q290
respectively. The audio output of IC240 has a DC component which is removed by
C249, and this then drives a speaker directly. The output of IC260 is fed into a line transformer to provide a balanced 2-wire or 4-wire, 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 monitoring of the audio signal (on = audio muted; off = audio unmuted).
The mute control line is available on pad 234 ("RX GATE OUT") for control of external
circuitry. A high (9V) on pad 234 indicates that the audio is disabled and a low (0V)
indicates 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 (refer to Section 1.4 in Part G).
An undedicated relay is provided (RL210) for transmitter keying or other functions and
this can be operated from the mute line by linking PL270.

The T835 is designed to operate off 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 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 provides 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 incorrect polarity. It also provides transient overvoltage protection.
Note:
23/07/99
A fuse must be fitted in the power supply line for the diode to provide effective protection.

Figure 2.5 T835 Microcontroller Block Diagram
Overall system control of the T835 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 (refer to Section 5.3).

Figure 2.6 T835 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 increasing control voltage.

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 oscillation. The VCO control voltage from the loop filter (IC750) is applied to the varicaps
(D1-D4) to facilitate tuning within a 3MHz band of frequencies. A trimcap (CV1) 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 +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 either 157-177MHz or 169-196MHz according to product type (refer to Section 1.4). The VCO is tuned to 21.4MHz above the desired receive
frequency (high side injection) to produce a 21.4MHz 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 IC350. Buffering is provided by IC390 and the 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.

Introduction
When you receive your T835 receiver 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
3MHz switching range (i.e. ±1.5MHz from the factory programmed frequency), you
should only need to reprogram the receiver with the PGM800Win software (refer to the
PGM800Win programming kit and Section 3.2 below).
However, if you want to switch to a frequency outside the 3MHz 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.

Continually decrease the RF level to maintain 12dB sinad.
Roughly tune IF coils L330/L340/L350, CV318 and quad coil L360 for best sinad.
While maintaining a low level unmodulated RF input to the receiver, loosely couple into the first IF an additional high level signal at 21.4MHz - 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 8 (i.e. after the TCXO buffer) via an oscilloscope probe to measure
the TCXO frequency directly (12.8MHz). At this point the voltage level is
approximately 4V p-p.
Readjust L410, L420, L460 & L470 to give best sinad.
Change the RF signal level to -75dBm and modulate with ±3kHz deviation
(±2.4kHz) [±1.5kHz] at 1kHz.
Connect an oscilloscope probe to the RSSI test point (TP310) and connect plugs
PL210 and PL220 to give a flat audio response (refer to Section 3.5).
Readjust IF coils L330/L340/L350, CV318 and quad coil L360 to give a maximum
amplitude response on the oscilloscope with minimal amplitude modulation.
Note:
If you would like a more accurate method of tuning the IF, refer to the sweep
tuning method described in Section 5.5.5.
Further adjust these coils, along with L360, for minimum audio distortion, ensuring that the 455kHz level (on the oscilloscope) does not fall significantly.
Check that the distortion reading is:
wide bandwidth
mid bandwidth
narrow bandwidth
≤2%
≤4%
≤4%.
Reconnect plugs PL210 and PL220 to give a de-emphasised audio response (if
required) and reduce the RF level until 12dB sinad is reached. The receiver sensitivity should be better than -117dBm, assuming that the audio levels are not being
overdriven (refer to Section 3.11).

Visual Checks
Remove the covers from the T835 and inspect the PCB for damaged or broken components, paying particular attention to the surface mounted devices (SMDs).
Check for defective solder joints. If repair or replacement of components is considered
necessary, refer to Section 3 of Part A.
5.2
Component Checks
If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, 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 better multimeter, using only the medium or low resistance ranges).
The collector current drawn by multi-junction transistors is a further guide to their performance.
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.

Check the 5V digital regulator output at the junction of C611A (+) and IC610 pin 2
in the regulator compartment.
5.4.2
VCO Locking
Using a DMM, monitor the VCO control voltage at PL4-1 or the junction of L1 &
R1 on the VCO PCB.
If the synthesiser is locked and the VCO aligned, the voltage at this point should
be between 5 and 13V.
If the VCO is not locked, refer to the synthesiser fault finding charts (Section 5.7.3).

RF Sensitivity
Ensure that the VCO is on the correct frequency and the receiver correctly aligned.
Check that links SL405 to SL440 and link B in the front end are set correctly for the
operating frequency (refer to Section 3.7).
Check that the 12dB sinad sensitivity into the front end is as follows:
-117dBm (de-emphasised response)
-111dBm (flat response).
If the sensitivity is poor, you can trace the fault by measuring the sensitivity into
successive circuit blocks. Prepare a test cable by connecting a 1nF capacitor to the
end of a length of coax cable as shown in Figure 5.1.

Apply an on-channel RF signal modulated at 10Hz (sine wave) with approximately ±12kHz (±9kHz) [±6kHz] deviation at an amplitude of -80dBm.
Connect the modulating 10Hz audio signal to the "X" input of an oscilloscope and
observe the 455kHz IF input to IC350 pin 16 via a suitable RF probe on the "Y"
input. Alternatively, use an oscilloscope probe for the "Y" input to monitor the
RSSI output voltage at TP310 (RSSI test point) or pin 5 of D-range 1 (PL100). This
will give a demodulated log response and only the top half of the wave forms
shown in Figure 5.2 and Figure 5.3 will be displayed on the oscilloscope screen.
Note:
The X input should be DC coupled.
Check that the swept response has a rounded top and no sharp non-linearities

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 (this table also appears in the resist layer on the bottom side of the PCB). In this example, the resistor indicates that the product was built as a T835-10-XXXX.

PRODUCT TYPE
Note:
PRODUCT TYPE
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 therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying
the PCB for service purposes.
Note:
Copyright TEL
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 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, as shown below:
circuit reference lists components

order
variant column indicates that this is
a variant component
which is fitted only to
the product type listed
description gives a brief description
of the component
Internal Part Number order the component
by this number
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 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.
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:

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

Using CAD Circuit Diagrams
Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric
border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit
that is spread over two or more sheets.
When a line representing part of the circuitry is discontinued, a reference will be given at the end of
the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to
the sheet number and the last two characters refer to the location on that sheet of the continuation of
the circuit (e.g. 1R3).

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 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 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.

Introduction
The T836 is a synthesised, microprocessor controlled FM base station transmitter
designed for single or multichannel operation in the 136 to 174MHz frequency range1
with a standard power output of 25W. The RF section of the transmitter comprises a frequency synthesiser which provides 170mW of frequency modulated RF drive to a two
stage, wide band output driver followed by a 25W power amplifier. A thermal shutdown feature is provided in the T836 in case operating temperatures exceed acceptable
levels.
The T837 is a synthesised, microprocessor controlled FM base station exciter designed
for single or multichannel operation in the 136 to 174MHz frequency range1. With a
standard power output of only 800mW, the exciter is designed for use with the T838
50W or T839 100W power amplifiers. The RF section of the exciter comprises a frequency synthesiser which provides 170mW of frequency modulated RF drive to a two
stage, wide band output amplifier.
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 section 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 T836 and T837 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 136-174MHz frequency range, the T836 and
T837 have an 8MHz switching range (see Section 1.2.3 and Section 3.1).

Figure 2.3 T836/837 Microcontroller Block Diagram
Overall system control of the T836/837 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 (refer to Section 5.3).

Figure 2.4 T836/837 Synthesiser Block Diagram
The synthesiser (IC740) employs a phase-locked loop (PLL) to lock a voltage controlled
oscillator (VCO) to a given reference frequency. The synthesiser receives the divider
information from the control microprocessor via a 3 wire serial bus (clock, data, enable).
When the data has been latched in, the synthesiser processes the incoming signals from
the VCO buffer (fin) and the phase modulator (fref).
A reference oscillator at 12.8MHz (IC700) is buffered (IC710 pins 3 & 4) and divided
down to 200kHz (IC730). This 200kHz square wave is then summed with the modulating 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-modulated 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 synthesiser IC (IC740).
A buffered output of the VCO (Q795) is divided with a prescaler and programmable
divider which is incorporated into the synthesiser chip (IC740). This signal is compared
with the phase modulated reference signal at the phase detector (also part of the synthesiser 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 filtered to attenuate noise and other spurious signals. Note that the VCO frequency
increases with increasing control voltage.
If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. This
signal is filtered and buffered by IC750 pins 1, 2 & 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.

Two Point Modulation
M830-00
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 modulation 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 modulation frequencies greater than 300Hz the loop cannot correct fast enough and modulation 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 sections (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.

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 oscillation. The VCO control voltage from the loop filter (IC750 pin 7) is applied to the varicaps (D1-D4) to facilitate tuning within an 8MHz band of frequencies. A trimcap (CV1)
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 +22dBm
(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 multiplier 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 supply 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.

General
The audio processor comprises several link selectable circuit blocks which may be configured 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-amplifier (Q210) and ultimately to a multiplexer (IC240), but in between may pass through
the compressor (depending on the linking details). The line transformer is also connected to the multiplexer and is disabled by the microphone PTT switch.
A third input for external CTCSS tones is also provided.

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 reliable 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 comparator (IC230) which toggles whenever the audio signal exceeds a DC threshold determined 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 completing the feedback loop.
The compression level is set by adjustment of the comparator threshold (RV220).
Note:
Although the high dynamic range of the compressor allows the use of very
low audio signal levels, such conditions will be accompanied by a degradation of the signal-to-noise ratio. Very low audio input levels should therefore be avoided where possible.
2.5.5
Outputs To Modulators
The output signal from the limiter (IC210, IC230) is added with a CTCSS tone at a summing 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 electronic potentiometer (EPOT), which is controlled via PGM800Win. The EPOT is made
up of 256 resistive sections (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 adjusting the absolute deviation level.

The T836 and T837 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 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 (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 incorrect polarity. It also provides transient overvoltage protection.
Note:
23/07/99
A fuse must be fitted in the power supply line for the diode to provide effective protection.

T836 Drive Amplifier & PA
M830-00
(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 (Q365, Q370). The forward and
reverse RF power levels are sensed via a dual directional coupler and detector diodes
(D410, D420 in the PA cavity). The detected DC signals are summed with the ’power
adjust’ level and fed to the control integrator (IC330 pins 1, 2 & 3). The output control
voltage is buffered by Q310 and Q315, and applied to the collectors of the wide band
exciter amplifier.
Note:
Forward and reflected power signals are summed so that, under high
VSWR, the power control will turn the output RF level down.
To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. and
Lock-Detect signals are gated to inhibit the PA control circuit and to switch off the RF
signal at the input to the drive amplifier. This is achieved by a PIN switch attenuator
(D340, D350, D360).
Cyclic keying control is provided by additional circuitry consisting of several time
delay, ramp and gate stages:
• Q350, Q355, Q360, IC330 pins 1, 2 & 3
power ramping
• Q340, Q345
Tx-Reg. and Lock-Detect gate
• Q320, Q325, Q330, Q335
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 500mW (+27dBm) for an input
of 170mW (+22dBm) when the power control is set to maximum.
The zener diode (D330) limits the upper range of the controlled voltage to the exciter
transistors.
A temperature sensor (R460) 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 (IC330
pins 5, 6 & 7, Q305) to prevent overheating, as the unit is not rated for continuous operation at high temperatures (refer to Section 1.2.3 for duty cycle specifications). RV330
sets the PA output power while under high temperature fold-back conditions.
R359, R360 and R362 form a 6dB attenuator to provide good VCO/exciter isolation.
The output attenuator (R392, R390, R394 and R396) aids in reducing exciter/PA interaction while also ensuring a reasonable match for Q350.
The RF output from the exciter is fed to the driver stage (Q415) and then to the final
(Q425). DC is fed to the final via a low pass filter with special low frequency decoupling. CV451 tunes the output matching across the entire band.

T837 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 (Q365, Q370) provides an output level of approximately 800mW (+29dBm) for an input of 170mW (+22dBm) from the VCO. IC330 pins
5, 6 & 7, Q310, and Q315 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
(D340, D350, D360).

Introduction
When you receive your T836 transmitter or T837 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 frequency), 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 programming 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.

Short Tuning Procedure
Use this procedure only if you want to reprogram the T836/837 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 programming 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 CV1 for a synthesiser loop voltage of
9V.
Multichannel
Tune VCO trimmer CV1 for a synthesiser loop voltage of
9V on the middle channel.
If there is no middle channel, tune CV1 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 frequency separation than the specified switching range of
8MHz.
3.4.3
Output Power Adjustment (T836 Only)
Connect an RF power meter to the output socket and key the transmitter.
Turn RV320 (power adjust) fully clockwise.
Tune CV451 (output power trim) for maximum output power and check that this
is >30W.
Adjust RV320 for the required output power (between 5 and 25W).
Readjust CV451 to reduce the supply current by up to 0.5A.

Two Point Modulation Adjustment
Note 1:
In this and following sections deviation settings are given first for wide
bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )
and narrow bandwidth sets [ ].
Note 2:
The reference modulation and limiter adjustments are controlled by 256step electronic potentiometers (EPOTs), which are adjusted via the “Reference Modulation” and “Deviation” settings in PGM800Win. This allows the
two point modulation and deviation settings to be adjusted for each channel.
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.

Inject an audio signal of 600Hz 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 (±2.4kHz) [±1.5kHz]
deviation at 600Hz.
3.
Change the input frequency to 120Hz and, using PGM800Win, adjust the value of
the “Reference Modulation” EPOT setting for the current channel to obtain ±3kHz
(±2.4kHz) [±1.5kHz] deviation (you can use either the mouse or up and down
arrow keys).
4.
Change the input frequency back to 600Hz.
Repeat steps 2 and 3 above until the deviations achieved at the two input frequencies 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:
or
- incorrect set-up
- modulation circuitry fault.
The specification window is ±1dB relative to 150Hz from 65 to 260Hz.

Audio Processor & CTCSS
3.9.1
Two Point Modulation
C3.11
The T836 and T837 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 frequency. The relative signal levels fed to the two modulators are quite critical and cause
interaction when setting up.
Both modulating signals require readjustment when the exciter is shifted in frequency
greater than the switching range (i.e. ∆F>±4MHz).
Note 1:
In this and following sections deviation settings are given first for wide
bandwidth sets, followed by settings in brackets for mid bandwidth sets ( )
and narrow bandwidth sets [ ].
Note 2:
The reference modulation and limiter adjustments are controlled by 256step electronic potentiometers (EPOTs), which are adjusted via the “Reference Modulation” and “Deviation” settings in PGM800Win. This allows the
two point modulation and deviation settings to be adjusted for each channel.
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.

Visual Checks
Remove the covers from the T836/837 and inspect the PCB for damaged or broken components, paying particular attention to the surface mounted devices (SMD's).
Check for defective solder joints. If repair or replacement is considered necessary, refer
to Section 3 of Part A.
5.2
Component Checks
If you suspect a transistor is faulty, you can assess its performance by measuring the forward and reverse resistance of the junctions. Unless the device is completely desoldered, 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 better multimeter, using only the medium or low resistance ranges).
The collector current drawn by multi-junction transistors is a further guide to their performance.
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.

Power Rails
M830-00
Refer to the test points and options diagrams in Section 6 for test point locations, and to
the regulator fault finding chart (Section 5.7.2) for fault diagnosis.
Check the 13.8V (TP601) and 9V (TP602) supplies at their test points in the regulator compartment with a DMM.
Check the 5V (TP604) and 20V (TP603) rails at their respective test points in the
regulator compartment.
Check that Tx-Reg. (TP305 in the exciter compartment) comes up to 8.8V when the
exciter is keyed.
Check the +5V digital regulator output (TP607 in the regulator compartment).
Check for short circuits.
5.4.2
VCO Locking
Key the exciter.
Using a DMM, monitor the VCO control voltage at PL4-1 or the junction of L1 and
R1 on the VCO PCB.
If the synthesiser is locked and the VCO aligned, the voltage at this point should
be between 5 and 13V.
If the VCO is not locked, refer to the synthesiser fault finding chart (Section 5.7.3).

T836 Drive Power
Refer to the drive amplifier fault finding chart (Section 5.7.4).
Ensure that the VCO locks (refer to Section 5.4.2).
Connect the drive output to a power meter and key the transmitter.
Check that the output power is between 600 and 1000mW.
Note:
If the synthesiser is out of lock, the lock detector (synthesiser IC740 and
comparator IC750) will prevent the RF signal from reaching the PA by
switching the supply to the exciter amplifier (Q340, Q345).

Audio And Modulation
Refer to the audio processor fault finding chart (Section 5.7.7).
Set up the audio processor as described in Section 3.9.
Check that the demodulated RF output has the frequency response referred to in
Section 4.5 with at least ±5kHz (±4kHz) [±2.5kHz] deviation available at 1kHz
modulating frequency.
If the above result is not achieved, either the two modulators are incorrectly adjusted or

PGM800Win Generated Errors
The following errors are those most likely to occur using PGM800Win. Refer to the
PGM800Win software user’s manual for a complete list of error messages.
Channel Switch Set
The programmed default channel change was not accepted by the base station because a
channel is selected externally. Try turning the external channel switch off to change the
default channel in PGM800Win.
Synth Out Of Lock
The synthesiser received incorrect data, or the data was corrupted. Enter a frequency
within the VCO switching range, or tune the VCO.
Internal Error
Data could not be read from the base station due to an internal error. Check for shorts
or open circuits on the SDA, SCK, SYNTH and EPOT lines. The SDA, SCK and SYNTH
are normally high, and the EPOT is normally low.
Write/Read To An Unlinked Module
The link to the module does not exist. Undefined error.

As the location of certain components in the PA is critical to performance, it is important that any components removed or disturbed are
refitted in exactly the same position.
Caution:
Before attempting to remove a transistor, note the position, type and
value of each capacitor and resistor so that it can be replaced in exactly
the same position (refer to Figure 5.2).
Caution:
Do not apply too much heat or pressure to the PCB pads and tracks as
you may damage them or lift them from the PCB, causing permanent
damage to the transmitter.
Remove the resistors and/or chip capacitors 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 transistor stud nut and remove the device.
Remove any excess solder from the PCB pads with solder wick.
Trim the tabs of the replacement transistor so that the device sits neatly on the
PCB pads provided.
Lightly tin the underside of the transistor tabs. Remove any excess solder to leave
a thin, even layer on the tabs.
Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) to
the transistor mounting surface. Sufficient compound should be used to ensure
an even film over the entire mounting surface.
Place the transistor on the PCB in the correct orientation and ensure the tabs are
flush to the surface. Lightly solder one tab to the PCB. Torque down the retaining
nut to the correct torque (0.7Nm/6in.lbf.).
Caution:
Copyright TEL
Do not solder all the tabs before torquing down otherwise the device
may be broken.

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 Figure 1.1 in Part A shows typical labels). You can further verify the product type by checking the
placement of an SMD resistor in the table that is screen printed onto the top side of the PCB, similar
to the example drawn below (this table also appears in the resist layer on the bottom side of the
PCB). In this example, the resistor indicates that the product was built as a T836-10-XXXX.

PRODUCT TYPE
Note:
PRODUCT TYPE
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. 220-12345-00, 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 therefore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying
the PCB for service purposes.
Note:
Copyright TEL
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 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, as shown below:
circuit reference lists components
in alphanumeric
order
variant column indicates that this is
a variant component
which is fitted only to
the product type listed
description gives a brief description
of the component
Internal Part Number order the component
by this number
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 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.
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 alphanumeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams
Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric
border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit
that is spread over two or more sheets.
When a line representing part of the circuitry is discontinued, a reference will be given at the end of
the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to
the sheet number and the last two characters refer to the location on that sheet of the continuation of
the circuit (e.g. 1R3).

T837 Parts List (IPN 220-01390-02)
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 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 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.

T837 Parts List (IPN 220-01390-03)
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 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 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.

Introduction
The T838 & T839 are FM base station power amplifiers designed for single or multichannel operation in the 136 to 174MHz frequency range. The typical output power capabilities are as follows:
T838 T839 -
10 to 60W
20 to 120W.
The T838 PA comprises a single broad band RF power module whose output is filtered
before being fed to the output socket.
The T839 PA comprises two broad band RF power modules whose outputs are recombined (using a quadrature hybrid combiner) and filtered before being fed to the output
socket. This dual module design enables the transmitter to produce at least one quarter
of its rated power if one of the modules fails.
VSWR and thermal protection is 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 main PCB is mounted directly on a die-cast chassis/heatsink. Extensive use is
made of the latest surface mount technology. Effective RF isolation between the PA control circuitry and RF stages is achieved by internal metal shields.
Forced air cooling for the heatsink is provided on the T839 by a fan, which is activated
whenever the transmitter is keyed. Thermal sensors will also activate the fan automatically if the internal temperature reaches an unacceptable level.
The T838 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. The T839 has a width of
120mm and occupies a double space.

The T838/839 comprise a single stage RF power amplifier with extensive control circuitry:
• in the T838 this stage consists of a single, two-stage RF power module which
increases the drive level to approx. 60W;
• in the T839 this stage consists of two, two-stage RF power modules, each of
which increases the drive level to approx. 60W; the outputs from these modules are then combined to provide the rated output power.
Figure 2.1 and Figure 2.2 show the configuration of each of the main circuit blocks on a
functional level, while the fold-out Figure 1.1 shows their location on the PCB.

RF Circuitry
M830-00
(Refer to the RF & thermistor control sections circuit diagram in Section 5.)
The T838 consists of a single RF power module (#IC201) which delivers 60-70W. The
input signal is fed directly into the module, and the output from the module is passed to
the antenna socket via the directional coupler and low pass filter.
The T839 consists of two RF power modules (#IC201 & *#IC202), each of which delivers
60-70W. The input signal to these modules is split via a 3dB quadrature hybrid (*IC203).
The outputs from the modules are recombined by a second 3dB quadrature hybrid
(*IC205) before being passed to the antenna socket via the directional coupler and low
pass filter.
The directional coupler senses forward and reflected power, which is rectified (D201 &
D203) and passed to the control circuitry for metering, alarm and power control purposes.
Power control is via a series pass transistor (Q137), which controls the supply voltage on
pin 2 of #IC201 in the T838, and pin 2 of both #IC201 and *#IC202 in the T839.

T838/839 Circuit Operation
2.3.1
Power Control
M830-00
The DC voltages from the directional coupler representing forward and reflected power
are buffered by the two voltage followers, IC103 pins 1, 2 & 3 and pins 8, 9 & 10. Their
outputs are summed at an integrator (IC105 pins 1, 2 & 3), which drives the series pass
control elements (Q135 & Q137).
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
Driver Power Level
The maximum output power of the T838/839 can be limited by placing a ceiling on the
driver output power level using RV115 (accessible through the side cover). For example, if RV115 is set for a maximum output power of 50W, the range of adjustment using
RV109 (front panel power adjust) will be 20 to 50W.
Caution:
2.3.3
The driver power level clamp (RV115) is factory set to give a maximum
power output of 60W for the T838 and 120W for the T839. The unit may
be damaged if this level is increased.
Thermal Protection
At excessively high temperatures, the output power will automatically reduce to a preset level (set by RV113), thus preventing the PA from overheating.
Ambient temperature within the PA is measured by a thermistor controlled voltage
divider (R168, R237) which applies a voltage to a comparator with hysteresis (IC101
pins 8, 9 & 10). This thermistor is located on the PCB in the low pass filter cavity.
Thermal protection is also provided for each RF power module to prevent the module
itself from overheating. This protection consists of a thermistor controlled voltage
divider (R207, *R215 and R220, R219) which sets a voltage on a comparator with hysteresis (IC204 pins 1, 2 & 3 and 5, 6 & 7). These thermistors are located on the module
flanges.
The output current from all comparators is summed into the power control network via
RV113 so that the power level to which the PA must turn down may be set.

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).
IC103 pins 12, 13 & 14 and pins 5, 6 & 7 form comparators with thresholds adjusted via
RV101 and RV105 respectively. The inputs are from the forward and reverse power signals from the directional coupler, buffered by IC103 pins 1, 2 & 3 and pins 8, 9 & 10.
Thus, the power levels at which the forward and reverse power alarms are triggered are
defined by RV101 and RV105 respectively.
2.3.5
Forward And Reverse Power Metering
Forward and reverse power signals from the two IC1 buffers are available for metering
purposes. The output currents are adjustable via RV103 (forward power) and RV107
(reverse power).

Comparator IC101 pins 12, 13 & 14 are set to switch at heatsink temperatures greater
than +90°C or RF power module flange temperatures greater than +110°C, and pins 1, 2
& 3 at temperatures less than -10°C.
A logic AND function is applied to the comparator outputs by *Q103 and *Q105,
thereby turning on the fan unconditionally (via *Q107 and *Q109) if the heatsink temperature exceeds +90°C or the module flange temperatures exceed +110°C.
A logic OR function is applied to comparator IC101 pins 12, 13 & 14 and Tx KEY signals,
thereby turning on the fan when the transmitter is keyed and the temperature is
between -10°C and +90°C (or +110°C for the module flanges).
If the temperature drops below -10°C, *Q105 is turned off, preventing *Q103 from activating the fan.

The T838/839 are designed to operate off a 10.8-16V DC supply (13.8V nominal). A 7V
supply runs directly off the 13.8V rail, driving the fan control, power control and alarm
circuitry.
A crowbar diode is fitted for protection against connection to a power supply of incorrect polarity. It also provides transient overvoltage protection.
Note:

Setting The Output Power
Caution:
M830-00
If the high temperature shutdown power level has not yet been set or is
unknown, check that the unit does not overheat while setting the output 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 leads (or
connectors instead of leads) between the T838/839 and power meter set-up.
Note 2:
You will need appropriate extension leads if you wish to carry out the
adjustment procedures with the T838/839 withdrawn from the rack in the
latched position. Alternatively, disconnect and withdraw the T838/839 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 1W
full scale reading. Special BNC/N leads will be required.
Connect an RF power meter to the PA output.
Set the front panel power control preset (RV109) fully clockwise.

The side cover access hole for the driver power clamp (RV115) is covered
with a tamper-proof sticker. The clamp has been factory set to 60W (T838)/
120W (T839) maximum output power and should not normally need
adjustment. If the output power level is low, check that the high temperature shutdown circuit has not activated by verifying that IC101 pin 8 is low.
Adjust RV109 to set the power output to the required level (e.g. 50W for the T838,
100W for the T839).

Replacing RF Power Modules
Caution:
Follow these instructions carefully, otherwise the module can fail
because of poor heatsinking or cracked substrates.
Caution:
Do not apply too much heat to the original type of thermistor assembly
as the epoxy used may give off fumes that will cause eye irritation. If
necessary, replace this device as a complete assembly (see note 1 below).
Desolder the module and thermistor1 legs by heating with a soldering iron and
lifting away from the PCB with a screwdriver or thin stainless steel spike.
Undo the module screws and remove the thermistor assembly.
Desolder and remove both earth tags.
Gently lift the module away from the heatsink.
Note:
The module may be stuck down quite firmly with heatsink compound. You
may need to carefully prise it away from the heatsink with a small screwdriver. Keep the heatsink compound clean while the module is detached.
Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) to
the replacement module mounting surface. Use enough compound to ensure an
even film over the entire mounting surface.
Reposition the module in the correct orientation and ensure it is well pasted to the
heatsink.
Replace the earth tags and thermistor1 assembly in their original positions and
hand-tighten the screws, ensuring the tags and thermistor remain in place. Alternately tighten each screw evenly, finally torquing them down to 56N.cm/5in.lbf.
with an accurate torque driver.
Caution:
It is essential that you apply the correct torque to these screws to allow
the module flange to expand and contract under temperature cycling.
Also, do not solder any module legs before torquing down otherwise
the device may be broken.
Solder all module legs to the PCB.
Carefully solder the thermistor leg to the PCB1.
1. Later production PAs are fitted with a different type of thermistor which you
do not need to desolder from the PCB before removing a power module. Refer
to the top side PCB layout diagrams in Sections 5.2 and 5.3 for further details.

Remove the mounting screws for the TO-220 device(s): Q137 (and *R223 in the
T839).
Remove the screws securing the RF power module(s): #IC201 (and *#IC202 in the
T839).
T839 Only:
Remove the four hex nuts and washers from the splitter/combiner hybrids (*IC203 and *IC205).
Remove the 11 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:
#IC201, *#IC202 and *R223 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 module
which prevent effective earthing and/or heatsinking will cause catastrophic failure.
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 correctly positioned and not 'pinched'.
Make sure that the heatsink compound has stayed clean, and that the insulating
pad for Q137 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.
Caution:
Tighten the splitter/combiner hybrid hex nuts to a torque of 22N.cm/
2in.lbf. Any greater force will damage the devices.
Tighten the RF power module screws to a torque of 56N.cm/5in.lbf.
with an accurate torque driver. Deviating from this figure can cause
the device to fail (refer to Section 4.5).

The T838 and T839 share the same basic design and are built on the same PCB. However, in order to
simplify the presentation of the PCB information for each product, we have provided a separate
parts list, grid reference index and set of drawings for both the T838 and T839, even though this has
meant duplicating some information (e.g. grid reference index and circuit diagrams) in each section.

Introduction
Product Type Identification
You can identify the PA type by checking the product code printed on a label on the rear of the 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). You can further verify the PA type by checking the placement of an SMD
resistor in the table that is screen printed onto the PCB, similar to the example drawn below. In this
example, the resistor indicates that the product was built as a T830 Series I compatible
T838-10-XXXX. See below for further details on T830 Series I/Series II compatibility.

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

operation of the PA.
T830 Series I / Series II Compatibility
T838 and T839 PAs can be built compatible with either T830 Series I or Series II equipment. You can
check whether your PA was built as Series I or Series II compatible by checking the table that is
screen printed onto the PCB, as explained above.
The table below explains briefly the differences between Series I and Series II compatible PAs.
Apart from these differences, Series I and Series II compatible PAs are electrically and mechanically
the same. Refer to Part I for detailed information on Series I/Series II compatibility.
Note:
This manual covers the latest design T838 PA which uses an RF power module and is
identified by the product code T838-X0-XXXX.
Please refer to service manual
M830-00-100 for information on the earlier model (Series I) T838 PA which is identified
by the product code T838-10.

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 therefore 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 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, as shown below:

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

Using CAD Circuit Diagrams
Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric
border. The circuit diagrams in this manual use letters to represent the horizontal axis, and numbers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit
that is spread over two or more sheets.
When a line representing part of the circuitry is discontinued, a reference will be given at the end of
the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to
the sheet number and the last two characters refer to the location on that sheet of the continuation of
the circuit (e.g. 1R3).

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 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 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.

Because the circuit diagrams for this design cover both
products, we have indicated on the diagrams those
components which are placed only in the T838 by
enclosing them in a labelled box. The circuit reference
for each of these components is also prefixed with the
“*”character.
The “*” character is used in this parts list to indicate
components used only in the T838.

T839 Parts List (IPN 220-01404-03)
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 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 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
D101, D105
Removed from the main PCB and replaced by two 1N4148 diodes (IPN 001-50012-00) placed on the D-range
PCB: one soldered between PL101 pins 5 and 7 (cathode), the other between PL101 pins 6 and 8 (cathode). To
allow external power meters to read zero and still provide meter overvoltage protection (710978).
D113
Changed from MR750 (IPN 001-00011-60) to MR2520L (IPN 001-00012-90) to provide overvoltage transient suppression (750087/88/89/90/91/92).
IC204
Changed from LMC622CM to LM358 (710382).
*L236

Description
Note: The T838 and T839 share the same basic design and
are built on the same PCB. While most components in
this design are common to both products, there are a
number of components that are placed in only one product.
Because the circuit diagrams for this design cover both
products, we have indicated on the diagrams those
components which are placed only in the T839 by
enclosing them in a labelled box. The circuit reference
for each of these components is also prefixed with the
“*”character.
The “*” character is used in this parts list to indicate
components used only in the T839.

Introduction
PCB Identification
All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which
is screen printed onto the PCB (usually on the top side), as shown in the example below:
The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,
02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore 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 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, as shown below:
circuit reference lists components
in alphanumeric
order
variant column indicates that this is
a variant component
which is fitted only to
the product type listed
description gives a brief description

Internal Part Number order the component

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 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.
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:

T830 VCO Parts List (IPN 220-01176-03)
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 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.

N-Type Connector Assembly
Make sure that any N-type plugs connected to Tait equipment are assembled according
to the manufacturer’s instructions. It is particularly important that the centre pin in the
plug is positioned correctly:
• if the pin is positioned too far back in the plug, it may not make good contact
with the socket;
• if the pin protrudes too far (as shown in Figure 4.1), or is not straight, it may
damage the socket when the plug is screwed in.

Flat Or De-emphasised Response
G1.1
The links of PL210 and PL220 may be set to give either a flat or de-emphasised audio
frequency response (refer to Section 1.7 for further details).
1.2
Mute Relay Control
A relay with undedicated contacts (RL210) is available in the audio processor circuit
block for various switching applications. A link (PL270) is available for control of the
relay from the mute circuit (refer to Section 1.7). This makes the relay suitable for controlling the keying of a transmitter in repeater applications.
1.3
Mute Selection
Link PL250 may be set to operate with noise mute or carrier mute (refer to Section 1.7).
1.4
Receiver Disable
The receiver audio can be disabled by pulling the RX-DISABLE line low. When the circuit is pulled from low to high, the receiver audio cannot be re-enabled until the disable
timer completes its operation. This time is variable from 15ms to 200ms by adjusting
RV220 in the audio processor section.
If required, the operation of this circuit can be disabled by changing the link of PL260
from 1-2 to 2-3.
Typical applications of the receiver disable are as an extra mute for signalling purposes,
or when the T835 is configured as a line controlled base station (refer to Section 4).

Line Transformer Inputs And Outputs
The line transformer (T210) is designed to provide a balanced interface to 600 ohm lines.
For normal operation the two centre connections (LINE I/P 2, LINE I/P 3) are shorted
together, and the 600 ohm line is connected between LINE I/P 1 and LINE I/P 4.
The secondary winding of the transformer is connected via 1k and 10Ω (R160) resistors
to pin 6 (AUDIO-2) of D-range 1 and may be used to monitor audio on the line. Pin 7 of
D-range 1 can be reconfigured as AUDIO-1 by removing R808 and R160, and placing
%R150 (refer to Section 2 in Part I for more details).
2.3
Opto Key
The keying circuitry may be completely isolated from the rest of the system by means of
the optocoupler (IC250) connected between pins 11 and 12 of the D-range connector. A
constant current source (Q270) allows keying voltages between 6 and 50V.
2.4
Relay Driver
A dedicated transistor (Q250) is provided for the purpose of switching an external (e.g.
coaxial) relay. The output is open collector and is activated by the Tx-reg rail. This output is available on pin 9 of the T800-03-0000 auxiliary D-range connector (D-range 2).

G3.1
Talk Through Repeater
In this configuration the receiver directly keys the transmitter when the signal is
received. The demodulated audio is fed via 600 ohm lines to the transmitter to modulate the carrier. The receiver and transmitter operate simultaneously and must therefore
be on different frequencies. The minimum frequency separation depends on the
duplexer used.

Line Controlled Base Without Talk

4.1
General
This installation contains a transmitter and receiver which may or may not be on the
same frequency, thus simultaneous transmission and reception is not possible. When
the transmitter is keyed, the coaxial relay is also energised. When the relay is in its rest
position, signals from the aerial are passed to the receiver and the demodulated output
is fed via 600 ohm lines to the RCU.
The receiver is disabled when the transmitter is energised to prevent the receiver mute
opening from RF due to lack of isolation in the relay, direct radiation or the noise skirt of
the dual frequency link.
Since the base station may be controlled via a 2-wire line and a 4-wire to 2-wire hybrid,
there is a possibility of system oscillation if the receiver is not disabled during transmit.
This occurs when the transmit energy enters the receiver and produces an audio
response which can pass from the receive to the transmit audio part of the hybrid
(impedance imbalance, etc).

•
if the system configuration also uses an aerial changeover relay as well as the tail
timer, the changeover relay must be driven from the relay driver (Q250) in the
audio processor, rather than by Tx key or Tx enable; this output is available on
pin 9 of the T800-03-000 auxiliary D-range (D-range 2);
•
depending on tail time requirements, it is possible for the transmitter tail time to
exceed the receiver disable time capability; in this situation the receiver disable
line should also be driven from relay driver Q250 (D-range 2 pin 9).

DC Line Keying
M830-00
G5.1
DC Line Keying
Where the transmitter and receiver are separated by only a short distance and DC isolation is not required, DC loop keying may be employed.
A small DC current (usually less than 10mA) can be fed via the balanced 2-wire line to
provide remote control of various functions.
In a duplex system the receiver mute is used to key a transmitter, provided there is a
common earth between the two units (refer to Figure 5.1).

The kit comes complete with fitting instructions and all installation hardware.
T800-06-0001 External Frequency Reference Kit
The T800-06-0001 is the same as the T800-06-0000 kit with the addition of a special coax
cable for external frequency reference input. One end of this coax is terminated with a
miniature RF connector which fits into the D-range socket in an appropriate backplane
PCB (e.g. T800-52-0000) to connect to a T800 Series II module fitted with a T800-06-0000
kit. The other end is terminated with a BNC connector which can be mounted on the
rack frame.
T801 Frequency Reference Module
The T801 frequency reference module provides a high stability frequency source to
which the synthesiser within a T800 Series II base station can be locked. The master
standard within the T801 is primarily intended to be rubidium, although high quality
ovenised crystal oscillators can also be used in applications where more frequent readjustment of frequency is acceptable. The T801 converts the output frequency from its
master standard to the 12.8MHz required by the T800 Series II base station.
Refer to M801-00.
T801-10 OCXO Module
The T801-10 OCXO module provides a high stability frequency source to which the synthesiser within a T800 Series II base station can be locked. This will provide T800 Series
II transmitters with the frequency stability required for simulcast transmission. The
master standard within the T801-10 is a high quality ovenised crystal oscillator (OCXO).
Three outputs are provided on the rear panel, which allows up to three T800 Series II
transmitters to be referenced to the source oscillator.

Introduction
I2.1
You must make a number of modifications to enable a T830 Series II receiver, exciter or
transmitter to operate in a Series I rack frame. These changes can be split into two
groups, mechanical and electrical, as described below.
Mechanical
These changes involve:
• putting on a new front panel because of the differences in
height and width between a Series II and Series I panel;
• adding D-range locating pins as the Series I rack requires
them for alignment.
Electrical
These changes involve:
• making sure there is pin compatibility for D-Range 1 pin 7
between the Series II module and the Series I rack frame;
in Series I, pin 7 is allocated to audio 1 for the transmitter/
exciter, and audio 2 for the receiver;
• converting the exciter from rear RF output to front RF output;
• disabling cyclic keying in the exciter.
This procedure assumes you have already purchased the appropriate Series I conversion kit:
• T835 - T800-70-0035
• T836 - T800-70-0036
• T837 - T800-70-0037.
If not, you should purchase one from your nearest Tait Dealer or Customer Service
Organisation before beginning the procedure.
It should take approximately 15-20 minutes per module to perform these steps.

2.2
Method
Step
Action
Remove the Series II front panel from the module as follows:
M830-00
• remove the volume knob (T835 only);
• remove the four screws using a Torx screwdriver;
• push the LEDs from the front of the panel to remove them from
their grommets.
Remove both covers from the module.
Remove the M3 screws, spring washers, and M3 nuts from D-range 1.
Note:
If you have a chassis with threaded holes, you will need to
remove only the M3 screws and spring washers.
Replace the M3 screws with locating pins, M3 spring washers (and nuts
if necessary).
If you are modifying a T835, follow this step; otherwise go to Step 6.
Remove R808 (10Ω), as shown in Figure 2.1.
Ensure that R160 (10Ω) is placed, as shown in Figure 2.1.
This will convert D-range 1 pin 7 from serial com to audio 2.
Go to Step 8.

Action
If you are modifying a T836, follow these steps (refer to Figure 2.2):
• remove R808 (10Ω)
• remove R160 (10Ω)
converts D-range 1 pin 7 from
serial com to audio 1
• place %R150 (10Ω).
Continue with Step 8.
If you are modifying a T837, follow these steps (refer to Figure 2.2):
• remove R808 (10Ω)
• remove R160 (10Ω)
converts D-range 1 pin 7 from
serial com to audio 1
• place %R150 (10Ω)
• remove L390; this will disable cyclic keying to enable the T837
to work with a Series I PA.
Continue with Step 7.

T835/836/837 SII - SI Conversion
M830-00
Step
Action
Converting the T837 from rear panel RF output to front panel RF output.
Desolder, unscrew and remove the rear panel N-type connector.
Fit the blanking plate over the hole in the chassis from which the N-type
connector has been removed.
Unplug the existing coax from SK310 and SK420, retaining the spring
clip for the new coax cable.
Fit the front panel SMC connector:
• insert the coax fitted with the brass SMC connector through the
hole in the front of the chassis and secure with the brass nut
and washer;
• connect the coax from the SMC connector into SK310, securing
the coax in the groove provided in the chassis wall with the
spring clip (refer to Figure 2.3).
Fit all parts of the Series I front panel, following Step 1 in reverse order.
Note:
If you have difficulty refitting the LEDs, try pushing the
body of the LED back into the grommet with a thin screwdriver or spike. Be very careful while doing this as the legs
of the LED are very easy to break.
Replace the covers.

Programming
Once you have carried out this conversion procedure, you will no
longer be able to program the T830 Series II module via D-range 1.
In order to program the module now, you will need to use a programming module interface, such as the T800-01-0004. This device is fitted
with a programming socket and can be connected to the module via
SK805 in the microcontroller section. You will have to remove the top
cover (closest to the handle) to gain access to SK805.
Note:
30/04/98
You may still be able to program the module by connecting
the T800-01-0004 to a T800-03-0000 auxiliary D-range fitted
as D-range 2, but only if pins 8 (ground) and 12 (serial com)
of D-range 2 are not used in the Series I configuration.

Introduction
I3.1
You must make a number of modifications to enable a T830 Series II PA to operate in a
Series I rack frame. These changes can be split into two groups, mechanical and electrical, as described below.
Mechanical
These changes involve putting on a new front panel because of the
differences in height and width between a Series II and Series I
panel.
Electrical
These changes involve:
• inserting and removing components inside the module to
disable cyclic keying;
• converting from rear RF input to front RF input.
This procedure assumes you have already purchased the appropriate Series I conversion kit:
• T838 - T800-70-0038
• T839 - T800-70-0039.
If not, you should purchase one from your nearest Tait Dealer or Customer Service
Organisation before beginning the procedure.
Note:
This procedure applies to the latest design T838/839 PAs which use RF
power modules and are identified by the Series II style product code
T83X-X0-0000.
It should take approximately 15-20 minutes per module to perform these steps.

Method
Step
Action
Remove the Series II front panel from the PA as follows:
M830-00
• remove the four screws using a Torx screwdriver;
• push the LEDs from the front of the panel to remove them from
their grommets.
Remove the side cover.
Follow the step for whichever module you are going to modify:
• T838 - go to Step 4;
• T839 - go to Step 5.
These modifications will disable the cyclic keying.
T838
Remove *L201 (330nH SMD inductor), as shown in Figure 3.1.
Caution:
Do not use excessive heat to remove the inductor or it
will melt.
Place *R120 (0Ω SMD resistor), as shown in Figure 3.1.
T839
Remove *L211 (330nH SMD inductor), as shown in Figure 3.1.
Caution:
Do not use excessive heat to remove the inductor or it
will melt.
Place *R120 (0Ω SMD resistor), as shown in Figure 3.1.

Step
Action
Converting from rear panel RF input to front panel RF input.
M830-00
Remove the rear panel BNC connector:
• unplug the RF input coax from the socket on the PCB;
• unscrew the BNC connector from the chassis;
• carefully withdraw the coax from the module through the hole
in the rear of the chassis;
• fit the blanking plate over the hole in the chassis from which
the BNC connector has been removed.
Fit the front panel SMC connector:
• insert the coax fitted with the brass SMC connector through the
hole in the front of the chassis and secure with the brass nut
and washer;
• connect the coax from the SMC connector into *SK203 (T838) or
*SK201 (T839) as shown in Figure 3.2.
Refit the side cover.
Fit all parts of the Series I front panel, following Step 1 in reverse order.
Note:
30/04/98
If you have difficulty refitting the LEDs, try pushing the
body of the LED back into the grommet with a thin screwdriver or spike. Be very careful while doing this as the legs
of the LED are very easy to break.
