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:

Pozidriv & Philips Recess Head Screws
M830P-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).

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
M830P-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.

Introduction
The T837 is a synthesised, microprocessor controlled, DFSK low speed paging exciter
designed for single or multichannel1 operation in the 148 to 174MHz frequency range2.
With a standard power output of only 800mW, the exciter is designed for use with the
T839 100W power amplifier. 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. The synthesiser frequency is programmed via the serial communications port.
The low speed paging modulator section provides DFSK modulation. It incorporates a
TCXO frequency reference and uses two point modulation to achieve modulation of
data rates from 2400bps down to DC.
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 has two indicator LEDs to show when the transmit carrier is on (red)
and when the DC supply is connected (green). The T837 is 60mm wide and occupies a
single space in a Tait rack frame, which has the ability to accommodate up to seven
standard modules.
1. Although you can program the microcontroller with up to 128 channels, you must
carry out the modulation adjustment procedure if you change frequency (see Section
3.5).
2. Although capable of operating over the 148-174MHz frequency range, the T837 has an
8MHz VCO switching range (see Section 1.2.3 and Section 3.1).

Overall system control of the T837 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).
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);
• coordinate and implement timing control of the exciter;
• control the front panel "Supply" LED (refer to Section 5.3).

Figure 2.3 T837 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 12.8MHz reference frequency is fed from the paging modulator section to the frequency synthesiser Refin (IC740 pin 20). This reference frequency is derived from the
VCXO (X101), which is locked to the internal frequency standard provided by the TCXO
(X100). The reference frequency has been modulated in the VCXO by the incoming data
to allow the synthesiser loop to modulate down to DC. This 12.8MHz reference frequency is divided down to 6.25kHz or 5.0kHz in 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.

T837 Circuit Operation
2.3.1
Two Point Modulation
M830P-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 0 to 2400bps.
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.
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 data frequency
response of the transmitter remains unaffected.

C2.7
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 data signal onto the control
voltage and by frequency 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.

(Refer to the low speed paging modulator circuit diagram (sheet 2) in Section 6.2.)
2.5.1
General
The T837-2X-102X is a dedicated paging exciter. The low speed paging modulator section of the exciter accepts TTL data at the D-range input and modulates the synthesiser
using a two point modulation method that provides modulation of data input frequencies of 2400bps down to DC (all 1’s or all 0’s).
The paging modulator section incorporates a TCXO frequency reference and a modulatable VCXO which is locked to the reference frequency from the TCXO.
The paging modulator also has provision for fitting an optional FFSK modem PCB.

Figure 2.4 T837 AFC Block Diagram
The TCXO is the default frequency standard. In PLL mode, the slave 12.8MHz VCXO is
phase locked to the TCXO. Both the TCXO and the VCXO outputs are clipped in IC100
and IC102 and then frequency divided by 4 in the twisted ring counters, IC105 (TCXO)
and IC110 (VCXO). The slave VCXO is also fed to the synthesiser reference input.
Each twisted ring counter provides four divide-by-four outputs, the Q and not Q having
the relative phases 0°, 90°, 180° and 270°. These two signals are combined in the two
XOR gate phase discriminators in IC115 to provide two beat frequencies that are in
phase quadrature. Both these outputs are filtered to pass the low frequency beat signal,
which is a 5Vpp triangle wave.
The output from pin 8 of IC115 is then differentiated to provide a further 90° phase
shifted square wave output on pin 14 of IC120. The amplitude of the output is proportional to the frequency difference between the TXCO and the VCXO. The square wave
is then rectified by gating the signal with an inverted version of itself through a CMOS

switch. The switch is controlled by a square wave derived from the triangle wave on
pin 7 of IC120. This square wave will either be in-phase or inverted with respect to the
output on pin 14 of IC120, depending on whether the VCXO frequency is higher or
lower than the TCXO frequency.
The output from the CMOS switch (pin 14 of IC150) is a direct voltage which has amplitude and sense that is relative to the beat frequency. This signal is used as the control
voltage for the VCXO. The rectified signal is then summed with an inverted version of
the data, which cancels the effect of the data on the loop filter but still allows the VCXO
to follow the TCXO frequency. Although the VCXO and TCXO are not on the same frequency when data is being applied, the VCXO frequency will not drift with respect to
the TCXO.
2.5.3
Data Path
The input data enters the radio via pin 12 of D-range 1 (PL100). The data is fed into the
paging modulator at I/O pad P101, which is buffered by Q100, and then through an
XOR gate (IC115 pins 2 & 3) which gives the option of inverting the data.
IC140 pins 5 & 6 translate the level of the signal to 9Vpp, and then the data passes
through an attenuator and data filter. The data path is switched at the output of the filter by IC150 pins 1, 2 & 15, which allows the data to be removed from the AFC loop for
testing purposes.
From the switch the data travels three paths:
• The first path is via RV100 to the LOOP-MOD output to modulate the VCO.
• The second path is through RV101 to the summing amp. This data modulates
the control line of the VCXO, which produces the modulated reference.
• The third data path, which originates at the switch, is the feedforward data
path. The data is inverted, attenuated by RV102 and then summed with the
output of the AFC. The effect of this data path is to stop the loop filter from
correcting the VCXO frequency deviation caused by the data on the data line.
2.5.4
External Reference Frequency (T837-2X-1021 Only)
The paging modulator section of the T837-2X-1021 exciter incorporates an additional
synthesiser (*IC200) which can be configured to provide a 12.8MHz reference frequency
from an external frequency standard. This external frequency can be from 100kHz up to
25.6MHz in 100kHz steps.
When using an external reference, you must set the onboard synthesiser’s reference frequency according to the frequency of the external reference. This is achieved by placing
resistors *%R240 - *%R247 in a pattern corresponding to a binary number which represents the reference divider ratio (see Section 3.6).
The internal TCXO (%X100) is used as the standard reference frequency, but is phaselocked to the external frequency when this is applied.

01/07/00
C2.10
T837 Circuit Operation
M830P-00
When there is no external reference frequency present, *Q104 is turned off and *IC160
switches 2.5V DC to the AFC input of the internal TCXO. The reference frequency can
be adjusted by the trimmer on the TCXO itself.
When an external reference frequency is present, *Q104 switches on and *IC160 switches
the synthesiser phase detector output voltage to the AFC input of the internal TCXO. A
buffered 12.8MHz output of the internal TCXO is fed back to the synthesiser oscillator
input and compared with the external reference frequency, thus ensuring that the internal TCXO is phase-locked to the external reference frequency.
The synthesiser Lock-Detect signal drives an LED *D116 on the main PCB which is lit
when the synthesiser is locked to the external reference frequency. The Lock-Detect signal is also fed to pin 8 of D-range 1 (PL100) for external monitoring purposes. The output is low when the synthesiser is locked.
2.5.5
Keying Inputs
There are two ways to key the exciter:
• pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set);
• via the modem carrier detect line when the optional modem PCB is fitted.
Note:

The T837 is 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 modulator, and microprocessor.
A crowbar diode is fitted for protection against connection to a power supply of incorrect polarity. It also provides transient overvoltage protection.

Exciter Drive Amplifier
(Refer to Figure 2.1 and the exciter circuit diagram (sheet 3) in Section 6.2.)
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).
Cyclic keying control is provided by additional circuitry consisting of several time
delay, ramp and gate stages:
• Q305, IC330 pins 5, 6 & 7
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.
R359, R342 and R344 form a 6dB attenuator to provide good VCO/drive amplifier isolation.
The output attenuator (R360, R362, R364, R366) assists in reducing exciter/PA interaction while also ensuring a good match for Q370.
Note:

The exciter provides a DC control signal to the PA via the RF coax. This is
injected via L390.

Introduction
When you receive your 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 VCO switching range (i.e. ±4MHz from the factory programmed frequency), you
will need to:
• reprogram the exciter with the PGM800Win software (refer to the PGM800Win
programming kit and Section 3.2 below);
• carry out the modulator adjustment procedure described in Section 3.5.
However, if you want to switch to a frequency outside the 8MHz VCO switching range,
you will have to:
• reprogram the exciter with the PGM800Win software;
• carry out the synthesiser alignment procedure described in Section 3.4;
• carry out the modulator adjustment procedure described in Section 3.5.
3.2
Channel Programming
You can program up to 128 channel frequencies into the exciter’s EEPROM memory
(IC820) by using the PGM800Win software package and an IBM PC. You can also use
PGM800Win to select the exciter’s current operating frequency (or "default channel").
If the 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 exciter before it is installed in
a rack frame as follows:
• by using a T800-01-0010 calibration test unit;
• via D-range 1.
If you do not use the T800-01-0010, you will have to connect the PC to the 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.
1. Use the "Read Module" function in PGM800Win to find out what the default channel is.

Although the T800-01-0010 calibration test unit can be used to program the
T837 paging exciter, it is not suitable for tuning and adjustment procedures
because of the different pin allocations of D-range 1 (PL100).

Synthesiser Alignment
Ensure that the T837 has been programmed with the required frequencies using
PGM800Win software.
Select a channel using PGM800Win.
Connect a high impedance voltmeter to PL4-1 or the junction of L1 and R1 in the
VCO (this measures the synthesiser loop voltage).
Key the transmitter by earthing the Tx-Key line.
Tune VCO trimmer CV1 for a synthesiser loop voltage of 9V.
Check that the exciter output power is 800mW ±200mW (measured at the rear
panel N-type connector).
If required, measure and adjust the exciter output frequency as follows:
• apply +5V DC to pin 11 of D-range 1 (PL100) - this changes the mode of
operation to PLL so that the carrier frequency can be observed - and measure the output frequency at the rear panel N-type connector;
• adjust the trimmer on the TCXO (%X100) if required;
• remove the +5V DC from pin 11.
Caution:

This trimmer is susceptible to physical damage. Do not exert a downward force of more than 500g (1lb) when adjusting.

Modulator Adjustment
M830P-00
Apply +5V DC to pin 12 (DATA input) of D-range 1.
Monitor the exciter output frequency and adjust RV102 (DC frequency offset) to
give an output frequency of Fcarrier + 4.5kHz.
Remove the +5V DC from pin 12 and apply a 100Hz 5Vp-p square wave to pin 12.
Monitor the signal at TP100 with an AC coupled oscilloscope set to 50mV/div.
and adjust RV101 (reference modulation) until the triangle wave amplitude is
minimised.
Change the frequency of the square wave to 600Hz.
Monitor the frequency deviation on the exciter output with a modulation meter
and adjust RV100 (VCO modulation) to obtain ±4.5kHz deviation.
Monitor the VCO control line at PL4-1 or the junction of L1 and R1 in the VCO
using an AC coupled oscilloscope set to at least 20mV/div.
Change the frequency of the square wave back to 100Hz and check that the control
line still has a good trapezoidal wave form with flat top and bottom.
Note 1:
You may have to readjust RV101 & RV100 alternately to achieve a square
wave on the VCO control line at both 600Hz and 100Hz with a deviation of
±4.5kHz. Figure 3.2 shows a typical 100Hz VCO control line wave form
with RV101 and RV100 set correctly.
Figure 3.2 T837 100Hz VCO Control Line Wave Form
Note 2:
If the lower cut off frequency of an AC coupled oscilloscope is too high,
excessive distortion may be introduced which will result in ‘sag’ on the
square wave displayed. Determine if this is a problem by directly monitoring the original square wave source and observe any sag. If there is sag,
switch the oscilloscope to DC and use a 10µF capacitor in series with the
oscilloscope probe (observing the correct polarity) to directly monitor the
VCO control line. Note that the trace settling time will be approximately
one minute.

External Reference Frequency Configuration
(T837-2X-1021 Only)
When using an external reference frequency, you must set the onboard synthesiser’s reference frequency according to the frequency of the external reference. This is achieved
by placing resistors *%R240 - *%R247 in a pattern corresponding to a binary number
which represents the reference divider ratio.
If you are using a 10MHz external reference frequency, you need only carry out steps 4
and 5 in this section. You do not need to carry out steps 1, 2 and 3 because the T837 has
already been configured at the factory for a 10MHz external reference.
However, if you are using an external reference frequency other than 10MHz, you must
configure the internal synthesiser as described in steps 1, 2 and 3 before proceeding to
steps 4 and 5.
1.
Divide the external oscillator frequency by 100kHz.
2.
Convert the result to binary. You can use the following table to do this: select the
binary values in row three which add up to the result obtained in step 1, then
place a “1” in these positions and a “0” in the others.

Where there is a “0” in the binary number, place a zero ohm resistor in the corresponding component location shown in the table. Where there is a “1”, leave an
open link.

Visual Checks
Remove the covers from the T837 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.

Introduction
Product Type Identification
You can identify the 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. In this example, the resistor indicates that the product was built as a T837-20-XXXX.

Note:

837-23
837-15
837-25
The only function of this resistor is to indicate the product type. It has no effect on the
circuitry or operation of the 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:
If the variant prefix is. . .
the component will. . .
change according to channel spacing
change according to frequency stability
change according to frequency range
change or be placed/unplaced for special applications
be unplaced in one product
(where two products share the same PCB)
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.

Description
The T837-2X-1020 and T837-2X-1021 share the same
basic design and are built on the same PCB. However,
there are a number of special variant components in
these products.
The “*” variant prefix is used to indicate those components which are placed only in the T837-2X-1021.
The “%” prefix indicates components which are placed
in all product types, but may have different values in
each product type.
The “*%” prefixes indicate components which are
optional in the T837-2X-1021 only, and not placed at all
in the T837-2X-1020.

Introduction
The T838 & T839 are FM base station power amplifiers designed for single or multichannel operation in the 148 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
M830P-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
M830P-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:
Note 1:
M830P-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.
You must set up the T838/839 according to the following instructions before
operation in a radio system. Do not use the factory default settings as they
may not suit your operating frequency.
To obtain optimum performance from the T838/839, ensure that the exciter
used in this set-up procedure is the one that will be used with the PA in the
radio system.
Note 2:
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.
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.
Set the exciter to the required operating frequency.
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 connector.
With the exciter not keyed:
• remove the label over the adjustment hole for RV115 (driver power clamp);
• set RV115 to maximum (fully clockwise);
• set RV109 (front panel power control) to maximum (fully clockwise).
Key on the exciter.
Quickly (within 30 seconds) adjust RV115 until the output power is:
T838 T839 -

T838/839 Initial Adjustment
M830P-00
Caution:
D3.5
Do not allow the output power to exceed these levels as this will seriously reduce the reliability of the PA.
Do not use RV115 to set the output power as this will disable the thermal protection circuitry. The power clamp must always be 10W (T838)/
20W (T839) above the set output power.
Replace the label over the adjustment hole for RV115.

Remove the earth from pin 9 of IC101 (or the pad of R237).
To check the operation of the RF power module thermistor(s), place shorting links
across pins 1 & 2 and 2 & 3 of LINK201.
Check that the output power drops to:
T838 T839 -

Adjust RV101 (forward power alarm set) so that the forward power alarm LED
lights.
Check the alarm level setting by adjusting the power up and down and observing
the alarm LED. A few watts hysteresis can be expected.
Readjust RV109 for the normal operating level.
Note:
Remote indication is available at pin 3 of D-range 1.
3.7.2
Reverse Power
Power up the T838/839 and adjust RV109 (front panel power control) for the normal operating power level.
Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV105
(reverse power alarm set) so that the reverse power alarm LED lights.
Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad
(100W) to the PA output. This will result in a return loss of 6dB.
Note:
Remote indication is available at pin 4 of D-range 1.

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.
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.
Note:
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.

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 II compatible
T839-20-XXXX.

The only function of this
resistor is to indicate the
product type. It has no
effect on the circuitry or
operation of the PA.
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

variant column indicates that this is
a variant component
which is fitted only to
the product type listed
description gives a brief description

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).

Description
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 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
C155
Changed from 10n (IPN 015-25100-08) to 100n (IPN 015-26100-08) for T839-20-1020 product type. Circuit reference changed to %C155.
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
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
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:
If the variant prefix is. . .

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 3.1), or is not straight, it may
damage the socket when the plug is screwed in.

T800-55-0000 Backplane PCB
The T800-55-0000 paging backplane PCB is designed for use in the T800-28-0X00 paging
rack frame. The PCB mounts across the rear panel of the T800-41-0003 triple module
rack frame guide, and has provision for the following modules:
• high stability oscillator
• repeater/link receiver (optional)
• paging exciter/transmitter (25, 50 or 100W).
These modules plug directly into the D-range sockets provided on the inner side of the
PCB (both D-range 1 and D-range 2 are provided for). The other side of the PCB features:
• a programming port
• two DIP switches for external channel selection
• one 25-way OEM D-range connector (refer to Figure 2.1)
• one 11-way D-range connector with provision for an external frequency reference.
The T800-55-0000 also allows the fitting of an optional link transmitter/repeater, but
will not accept personality PCBs.

T004-72 RF Coaxial Relay
The T004-72 is an RF coaxial relay assembly fitted with three female N-type connectors,
and comes complete with a mounting bracket and two coaxial cables terminated in male
N-type connectors. It can be used, for example, in base station applications where the
receiver and transmitter share the same antenna, in which case it can be driven by the
T800 Series II transmitter/exciter relay driver.
External Frequency Reference
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.
Refer to M801-10.
