Warnings and Cautions
WARNING
Compliance with RF Energy Exposure Standards: To minimise exposure to RF fields during
equipment service and repair, the antenna terminal of the SRM9000 radio should be connected to
a suitable non-radiating RF load when the transmitter is in use.
WARNING
SRM9000 radio equipment is to be connected only to 12-volt negative earth systems. In vehicles
with a 24-volt supply, an approved 24V/12V converter must be used. The supply must not be
taken from a 12V tap on the battery.
WARNING
To avoid RF injury, do not touch the Antenna when the Transmitter is in use.
WARNING
Double-fused 12V Supply Leads, Antenna cables and Speaker wiring is to be routed as far away
as possible from gas or fuel lines or any electronic control device. The radio transceiver and
antenna are to be mounted as far away as possible from these devices and their cabling.
Equipment is to be installed, by a competent person, in accordance with the requirements of
local radio communications authorities and/or Health and Safety regulations.
Post installation checks should be performed to ensure that there is no effect on the operation of
the vehicle’s electronics.
WARNING
Do not operate your radio, without a handsfree kit, whilst driving a vehicle.
WARNING
Do not operate your radio in an explosive atmosphere. Obey the “Turn Off Two-way Radios”
signs where these are posted, e.g. on a petrol station forecourt.
Caution
During disassembly and assembly, refer to Torque Settings in Section 1.6
Caution
Customer configuration files should be saved prior to any alignment adjustments.
Preparing the radio for alignment will erase from the radio all customer PMR configuration data
(channel, signalling information etc). The only data retained by the Alignment Tool is the factory
alignment data for the radio (DAC settings for Tx power, front-end tuning etc).

INTRODUCTION
1.1
GENERAL
The SRM9000X8 800MHz mobile transceiver is designed for PMR operation in analog systems or P25 in digital
systems.
The SRM9000X8 transceiver can be used with either the SRM9022 Graphics Display Handset or the SRM9030
System Level Remote Control Head with Alpha capability.
1.2
SCOPE
This manual provides technical specifications, description and servicing details for the SRM9000 mobile radio
transceiver.
1.3
DESCRIPTION
The design concept utilises wide band techniques for RF transmit and receive circuitry with digital signal
processing of analog or digital modulation and demodulation. Electronic tuning is used throughout the mobile to
eliminate manual tuning and level adjustment.
A Digital Signal Processor (DSP) and a Programmable Gate Array (PLA) are used with other dedicated devices in
the SRM9000 to perform the following functions under software control:
•
Frequency Synthesis of all operating frequencies.
•
Modulation and demodulation of 12.5kHz or 25kHz FM signals or P25 digital modulation on a per
channel basis.
•
Modem functionality for specified data modulation schemes.
•
Filtering, pre-emphasis, de-emphasis, limiting, compression, muting, CTCSS, Selcall or any other
frequency or level dependent signal modification.
•
Serial communications with the Control Ancillaries and Alignment Tool.
•
Tuning Control data for Tx and Rx.
The SRM9000 basic Transceiver comprises a rugged extruded aluminium sleeve, which houses a single printed
circuit board assembly and provides all heatsink requirements. The sleeve housing is closed at each end by highimpact plastic end caps; all cable ports and mechanical interfaces are sealed against moisture and dust ingress.
The PCB assembly comprises a single, multi-layer PCB containing all the RF and control circuitry. The PCB seats
on an extruded aluminium tray that slides into the outer aluminium sleeve where it is secured with screws
accessed from the outside of the case. Provision is made under the main PCB tray assembly for additional
hardware options as well as optional accessories plugged directly into the main PCB.
There are two installation methods available for the SRM9000. The outer aluminium extrusion has side flanges that
allow the mobile to be bolted directly to any flat surface in the vehicle. A quick release cradle is also available.

SRM9000X8 800MHz SERVICE MANUAL
Software Versions and Naming
There are various associated items of Software (SW) required for the SRM9000 radio and programmer to operate.
This section simply defines the naming rules of the SW files to allow identification and conformity. This allows
different versions of SW to be distributed and co-exist without confusion.
The SRM9000 Transceiver has three items of SW for digital and analog PMR, Trunking and Alignment.
The 9022 Controller Mic/Handsets has one SW file for its PIC and the 9030 Control Head has two SW files for its
Flash and EEPROM.
Filename Structure
1.4.1
Basically the Filename Structure is defined as follows:
•
2 character Application code
•
2 or 3 character SW Type code
•
3 character version number
•
File Extension as required.
eg.
9etm533.bin
9ep_533.bin
9es_533.bin
9ecf101.hex
9ece101.hex
Application Code

1.4.4
Version Number
This is a 3-digit number allocated by Engineering to identify the SW version.
e.g.
1.4.5
103
Version 1.03
Exclusions
The Programmer SW does not follow the above rules as it is a PC based Program and its version number can be
easily identified by starting the SW. Later releases of SW will be backward compatible, unless deliberately not so,
in which case a different directory structure/path may be implemented.
1.4.6
Displaying Software Versions
Each Transceiver SW code file (e.g. 9etm533.bin, etc.) contains version information about itself and possible
compatibility with Programming SW.
For Radio SW saved on Disk, this information can be displayed via the Programmer function:
Options : Upgrade_Software : Get_File
© TMC Radio 2008
page 6
TNM-M-E-0022 Issue 1
SRM9000X8 800MHz SERVICE MANUAL
For Software loaded in the radio, information can be read from the Transceiver and displayed via the
Programmer function:
Options : Radio_Information
SRM9030 Control Head SW can be displayed on the Control Head by holding the ‘3’ button down when the radio
is switched on. SRM9022 Handset SW can be displayed by pressing the top side button when the radio is
switched on.
1.4.7
Automatic Version Upgrade Prompting
When a configuration is downloaded to the Transceiver, the Programmer performs a brief check on the SW
currently installed in the radio. If a later version of SW exists (on PC hard-disk) then the Programmer will prompt
the user with the following message:
NOTE. As early versions of FPP cannot recognise a more recent revision of the radio, it is important that the latest
FPP version is downloaded from http://www.tmcradio.com.
If YES is selected, the Transceiver Radio code is updated before the new configuration is downloaded.
If NO is selected, only the configuration is downloaded.
This process also updates the Startup code to ensure it is compatible with the loaded PMR code.
Note : If the …\SRM9000\FPP\RadioSW folder contains no files, then the above check will not be performed.

SRM9000X8 800MHz SERVICE MANUAL
Transceiver SW Description, Start-up and Backup-Software
1.4.8
The SRM9000 Transceiver software is split into the following separate modules:
•
Bootloader and Backup Software
•
Start-Up Software
•
PLA and PLA-Backup Software
•
Mainline PMR Software
When the Transceiver starts, it basically performs the following steps:
•
Initial execution starts with the Bootloader code, which attempts to load the Start-Up Software (if StartUp checksum is bad, then the Backup Software is loaded.)
•
Start-Up Software then downloads the PLA code (or PLA-Backup code if PLA checksum is bad) to the
PLA device. If both PLA and PLA-Backup checksums are bad then the radio is not operational and serial
communication is not possible.
•
Start-Up Software then reads the On/Off switch plus Ignition-Sense lines and compares these with
saved parameters to determine if the radio should be continue to power-up or switch itself off again.
•
Start-Up software then attempts to load PMR Mainline Software (dependent on saved parameter) and
switches execution to complete the power-up process and start normal operation.
If the Mainline Software cannot be loaded, or a Job file configuration has not been loaded (e.g. non-existent or
checksum fail) then execution switches to Backup Software until the error is corrected (e.g. by FPPing the radio).
There are three states that the radio can configure after switch-on:
1.4.9
•
Mainline PMR Software (normal power-up)
If the radio does not have a valid Job file configuration loaded, then it will display a “No PMR Cfg”.
•
Start-Up Software (characterised by “Alignment Mode” shown on the display). This is also the code that
is running when the radio is being aligned using the Alignment Tool.
•
Backup Software (via various paths from above.)
Wailing Siren (Boot-up Software Corrupted)
A “WAILING SIREN” sound is emitted from the Loudspeaker while the radio is running in Boot Backup Software.
In this mode the FPP can be used to re-load a Jobfile, or re-load Start-Up or Mainline Operating Software.
Simply writing a Jobfile to the radio should allow the FPP to determine and update the offending software –
however there may be instances where the FPP cannot determine this and the Start-Up and Mainline Software
should be updated manually. This can be done using the FPP : Upgrade_Software : Get_File … then Download.
Both Start-Up Software (filename = 9es_xxx.bin) and Mainline PMR (9ep_xxx.bin) should be loaded if the FPP
cannot automatically fix the problem. The wailing siren should stop once the problem is fixed.
Note:
1.5
Should these steps fail to restore the set and the Wailing Siren cease, the radio will need to be returned to
a Level 3 Service Centre for FLASH replacement.
ADJUSTMENT AND ALIGNMENT
There are no manual internal adjustments in the SRM9000. Re-programming and alignment is done using
software tools with the PCB installed in its chassis. For servicing, the radio PCB can be operated outside the
chassis provided that a temporary heatsink is fitted under the transmitter PA module for transmitter servicing and
that the receiver audio output be kept below 100mW for receiver servicing. Radio performance is only slightly
affected by operating without the outer sleeve but there will be some change to performance when the metal cans
are removed from the RF sections of the board.
On re-assembly, the PA module should be checked for a thin layer of heat-conducting paste. If this is missing or
dried-out, it should be replaced prior to re-assembly.

CHASSIS ASSEMBLY
Important Note!
1.6.1
Torque Settings
Assembly of 'Chassis' (Inner Extrusion) to 'Outer Extrusion': 1.4 Nm (PA x 2), 1.25Nm (Others x 3)
Assembly of 'Front' and 'Rear' end-caps to 'Outer Extrusion': 1.4 Nm.
1.6.2
Thermal Compound Application
Just enough thermal compound should be applied to the PA tray to provide good thermal contact with the chassis.
Note. If thermal compound is old and difficult to spread, it should be discarded.
1.6.3
Assembly
The Inner extrusion should initially be nested together with the PCB and then the assembly slid into place within
the outer extrusion.
Positioning the inner extrusion upwards by hand, it is then important to insert all screws by hand and ensure they
have been fully inserted through the PCB, thereby locating the assembly correctly.
Whilst holding the inner extrusion upwards to ensure the assembly does not twist, lightly torque up the centre
screw of the row of three followed by the PA module mounting screw towards the middle of the chassis.
The remaining screws can then be screwed up to full torque followed by re-torque of the first two screws.

3.1
TECHNICAL DESCRIPTION
RECEIVER
Refer to Figure 3-1.
3.1.1
Front End Filters and RF Amplifier
The receiver input signal from the antenna passes through the harmonic filter and antenna T/R switch. With the
mobile in receive mode, diodes D580, D582 and D583 in the antenna switch are reverse biased allowing the
receiver input signal to be coupled through to the receiver front-end with minimal loss. The overall insertion loss of
the harmonic filter and switch is approximately 0.8dB.
The signal is then fed through SAW bandpass filter (Z400) to the input of the RF amplifier (Q404). The SAW filter
bandpass covers 851MHz to 870MHz. The RF amplifier stage comprises a low noise transistor amplifier (Q404)
that is compensated to maintain good linearity and low noise matching; this provides excellent intermodulation and
blocking performance across the full operating range. The overall gain of the front-end is approximately 9dB.The
RF amplifier has constant current bias controlled by Q402. The output of the RF amplifier is coupled through a
varactor-tuned bandpass filter comprising of two ceramic resonators (Z430 and Z431). The varactors have
individual PWM tuning voltages, TUNE 1 and TUNE 2, that are derived from PLA (U300). The tuning voltages
values for the filter varactors are controlled by the alignment data stored in the radio. The DSP processes these
data to optimise the filter tuning for each of the programmed channel frequencies.
A negative bias supply originates from the DSP/PLA as a PWM signal for the two filter tuning voltages for the
specific channel frequency selected. The PWM signal, which is dependent on channel frequency and tuning,
passes through level shifting transistors Q451 to Q454, where it is converted to a negative voltage in the range
-0.5V to -11.5V. The -12.0V rail for the level translators is generated by U904E/F, with D903 to D906 providing the
required voltage multiplication.
3.1.2
First Mixer and IF Section
The output of the ceramic resonator pair is then fed into U441, a high performance passive mixer that converts the
RF signal to a IF of 45MHz. The first local oscillator injection level is typically +8dBm with high side injection.
Following the mixer is a IF amplifier (Q461) that provides approximately 15dB of gain and, in association with its
output circuitry, presents the required load conditions to the 4 pole 45MHz crystal filters Z471A/Z471B.
The crystal filters provide part the total required selectivity for adjacent channel operation with the remaining
selectivity provided by a DSP bandpass filter algorithm.
3.1.3
Quadrature Demodulator
Additional IF gain of approximately 44dB occurs in U481, which is a dedicated IF AGC Amplifier and Quadrature
Demodulator. The AGC voltage for U481 is derived from the RSSI function of the DSP. The onset of AGC
operation occurs when RF input signal level at the antenna connector exceeds -90dBm and can reduce the gain
by approximately 100dB for strong signals.
Conversion of the 45MHz IF signal to I and Q baseband signals is carried out by the demodulator section of U481.
The 90MHz second local oscillator signal for U481 is generated by VCO Q730, which is phase locked by the PLL
CPIF output of U721, via feedback signal FINIF.

Receiver Audio Processing
The baseband audio from the IQ Demodulator is applied to a differential amplifier (U941A/ U941B) that converts
the balanced demodulator I and Q output signals to unbalanced inputs for the CODEC (U800).
All receiver audio processing and filtering functions are performed by the CODEC under the control of the DSP.
The receiver I and Q analog baseband signals are converted to digital signals by the CODEC ADC before being
applied to a series of digital filters that provide the final stages of adjacent channel filtering, high pass and low pass
audio filtering, mute noise processing, and volume control level for narrow and wideband operation. The fully
processed signal is then converted to an analog audio signal by the CODEC DAC and then applied to conventional
audio amplifiers (U803A/B) and the loudspeaker amplifier (U805).
In addition, Discriminator Audio is derived from the second CODEC output channel and then amplified by U802A
after which it is applied to one of the radio I/O connectors for option purposes. Discriminator Audio is a preset level
set by the FPP and is independent of squelch operation.
There are two speaker options available, a half-bridged configuration using a speaker across balanced output
SPKR OUT1 and 2, which provides an audio output level of up to 4 watts into 4 ohms. The other option is a full
bridge configuration using a high power speaker across SPKR OUT1 and 2 and providing an audio output level of
up to 10 watts into 8 ohms; this high power option is enabled by adding 0 ohm resistor, R859. The carrier and
signalling mute functions are performed by Q810/Q811/Q813 under DSP control. De-emphasis to the audio PA
(U805) is performed by R861 and capacitor C872. Flat audio is provided to connector S1-6 via amplifier U803A.
3.2
TRANSMITTER
Refer to Figure 3-2.
3.2.1
Drivers and PA Stages
The carrier frequency for the transmitter is generated by combining the receiver first LO with the receiver second
LO in TX mixer (U650).
The output of the mixer (U650) is fed into a broadband amplifier (U670) via a tuned filter comprising of varactors
D660 and D661, to reduce the unwanted mixer products. The tuning voltage for the filter varactors, TUNE 1N, is
derived from level translators Q451 and Q452. U670 amplifies signals from 806MHz to 825MHz for two frequency
simplex applications and 851MHz to 870MHz for turnaround operation. The output of U670 connects to a diode
switch arrangement consisting of D681 to D684; this switch is used to select pairs of SAW filters on either the 806
to 825MHz band with Z681 and Z683, or the 851 to 870MHz band with Z682 and Z684. The diode switch is
controlled by transistors Q681 and Q682.
The carrier signal level at the output of the SAW filters is approximately –7dBm. This signal is then further
amplified in subsequent broadband stages Q691 to approximately +2dBm, Q501 to +15dBm, Q521 to +17dBm
and Q531a to +20dBm. Each of these stages has a resistive attenuator network to provide isolation from the
affects of transient load impedance changes. The output of final driver (Q531a) is fed through a resistive network
consisting of R536, R537 and R538, to the input of the broadband power amplifier module (U561) at a level of
approximately +16dBm.
The PA module (U561) contains three MOSFET stages to achieve the required maximum RF output power level of
+44.4dBm (27.5 watts).
Note: Care should be taken during servicing, since if for any reason the drive power is lost while the power control
voltage is high, the current into the PA may exceed its specification. Therefore the power supply current limit
should be monitored at all times and preset to as low as required. The radio has some additional inbuilt
safeguards, but these should not be relied on.
Final power output settings are derived from alignment data stored in flash memory during the initial factory
alignment. The DSP processes these data to optimise the power output level relative to the selected programmed
channel frequencies.
PA current is monitored via comparator U551B, the output of which is passed via a temperature compensation
network R552, R553 and NTC R554, to the ADC, U301C. U301C samples the applied voltage and then passes it
to the PLA, after which it is processed by the DSP. The PA current limit value is calibrated as part of the alignment
procedure.

3.2.2
Power Control
The final output power is stabilised by a power control feedback loop. A printed circuit transmission line, L561,
resistor R560, diodes D561A and D561B, and other associated components, form the power detector. Comparator
U551A and associated components provide the power setting and power control functions. Forward and reverse
power is sampled by the power detector and applied as a DC voltage to the inverting input of the comparator. The
TX_PWR set voltage is a DC voltage proportional to the programmed Tx power setting and is applied to the noninverting input of the comparator.
The TX_PWR calibration voltage originates from the PLA as a PWM signal and is integrated for application to the
comparator.
The PA module output level variation due to variations of supply voltage, output load or temperature, is detected
and applied to the comparator. The comparator proportionally adjusts the PA module bias supply and the bias
supply for the PA driver (Q531A) and thus the PA drive level. High temperature protection is provided by thermistor
R557, that progressively reduces the power level if the PA module temperature becomes excessive.
3.2.3
Antenna Changeover and Harmonic Filter
The antenna changeover circuit consisting of pin diodes D581, D582 and D583, is switched by transistors Q571,
Q572 and Q573 and associated circuitry, allowing the transmitter output to be coupled to the antenna while
providing isolation for the receiver input. With the transmitter switched on, the diodes are forward biased allowing
power to be coupled through to the antenna and isolating the receiver by grounding its input at C585. The short
circuit at the receiver input is transformed to an effective open circuit at D581, by a lumped transmission line
(L591), which minimises transmitter loading. With the transmitter switched off, the diodes are reverse biased
allowing the receiver input signal to reach the receiver front end with minimal loss. The harmonic reject, low pass
filter comprises L592, L593, L594 and associated capacitors.
3.2.4
Transmitter Audio Processing
The microphone audio input signal is applied to the radio microphone input (AUDIO_IN1) and is derived from an
external microphone and pre-amplifier that provides a typical speech signal level of 40mV RMS. U801A is a control
gate that switches between AUDIO_IN1 and OPTION_AUDIO1 to provide external audio options and data input.
U801C provides CODEC input switching which selects either the receiver “I” signal or transmitter audio/data
signals depending on the Tx/Rx mode. All pre-emphasis, filtering, compression and limiting processes for narrow
and wideband operation, are carried out in the DSP after A-D conversion by CODEC (U800). The processed
transmitter audio/data from the CODEC output at VOUTR, is applied to the VCO as a modulation signal with a
level of approximately 200mV P/P via AF Switch (U801B).

3.3
FREQUENCY SYNTHESISER
3.3.1
General
Refer to Figure 3-3.
The frequency synthesiser consists of the RX VCO, the second local oscillator VCO (90MHz), loop filters, varactor
positive bias generator, reference oscillator, external divider and an integrated fractional N phase locked loop IC
(U721).
3.3.2
PLL
The PLL is a high performance delta-sigma fractional-N device with an auxiliary integer-N PLL (U721).
The PLL contains two prescalers, programmable dividers and phase comparators, to provide a main and an
auxiliary PLL. The main PLL of U721 controls the frequency of the RX VCO via CPRF at pin 1 and VCO feedback
to FINRF at pin 4. The auxiliary PLL is used to control the receiver 90MHz second LO VCO via CPIF at pin 16 and
VCO feedback to FINIF at pin 13. The PLL operation involves the external frequency divider (U760) dividing the
15.36MHz reference oscillator by 32 to produce a PLL input reference of 480kHz; this reference is used directly by
the RF PLL phase detector. The RX VCO frequency is sampled and divided down and compared to the reference
frequency. Any error produces an offset to the control voltage output that is used to correct the VCO frequency. A
valid lock detect output is derived from LD pin 12 and is sampled by the PLA. During transmit, if an unlocked signal
is detected, the radio will switch back to receive mode. An unlocked signal in receive mode will cause the radio to
beep.
For the IF PLL, the input reference is divided by 4 to produce a 120kHz phase comparator reference, which is a
sub-multiple of the 90MHz second LO VCO.
3.3.3
VCOs
The main RX VCO uses a low noise bipolar transistor (Q623) and associated parts to generate signal frequencies
from 896MHz to 960MHz. Electronic tuning is provided by varactor diode (D610) with its control voltage derived
from the Loop Filter, PLL and +16 volt Bias Generator. VCO buffer (Q631 and Q632) isolates the VCO from any
load variations from its following circuits. The active power supply filter (Q622) minimises any supply related noise.
A PLL feedback signal is returned from the VCO buffer output via amplifier Q640.
The 90MHz receiver second LO VCO comprises Q730 and associated parts. Automatic tuning is achieved by
applying a control voltage to D730 and D731, via Loop Filter R718, R719, R720, C732, C733 and C734.
3.3.4
Positive Bias Generator and Loop Filter
A positive bias voltage for varactor D610, has been used to achieve the required broadband tuning range of the
VCO. PLL device, U721, is programmed to deliver a nominal +1.65V output from phase detector/charge pump
CPRF, for any channel frequency selected. The CPRF voltage is filtered by the Loop Filter comprising C605,
C607, C607a, C609a, R609 and R612; the loop filter removes any synthesiser noise or reference products. The
resulting low noise control voltage is applied to the anode side of VCO varactor. The cathode voltage of D610 is
controlled by the output of voltage level translator Q780, Q781, Q782 and Q783. The level translator supply
voltage is +16V, which is provided by U904E/F. The level translator output voltage is accurately controlled by the
PLA/DSP from values stored during VCO alignment. This voltage is varied versus frequency to maintain a typical
CPRF value of +1.65V.
3.3.5
Phase Modulator
The modulation path for audio, data and higher frequency CTCSS signals is via varactor D610 and associated
components. The reference input to the PLL (REFIN) provides the low frequency modulation path via a phase
modulator.
The phase modulator comprises the following sections:
- Integrator U761A is a low pass filter providing 6dB per octave attenuation to frequencies above approximately
10Hz.
- Divider U760 divides the 15.36MHz reference frequency down to 480kHz.
- Ramp generator Q771 and Q772 provides a sawtooth output, the slope of which is adjustable
via the MOD_BAL line. This adjustment is set via a DAC output controlled from the Alignment Tool.
Adjustment of the ramp slope effectively changes the Phase Modulator gain by modification of the
Schmitt Trigger switching points after modulation from the Integrator is combined to the sawtooth ramp.
© TMC Radio 2008
page 26
TNM-M-E-0022 Issue 1
SRM9000X8 800MHz SERVICE MANUAL
The divided reference signal is differentiated and discharges C778 via Q771, after which Q771 is turned off
allowing C778 to recharge via constant current source Q772.
The Schmitt Trigger comprising Q774, Q775 and Q776, converts the modulation combined with the sawtooth
ramp, to a square wave output, the duty cycle of which is controlled by the ramp slope and modulation.
The Modulation Balance adjustment is carried out using a CODEC-generated 100Hz square wave applied to
the TX_MOD input and set to give an optimum demodulated square wave output.
3.3.6 Reference Oscillators
Two TCXOs are used as optional reference frequencies for carrier frequency generation and also to provide the
DSP clock. U711 is the principal TCXO and operates at 15.36MHz and U712 is the alternate TCXO and operates at
approximately 15.359767MHz. The alternate TCXO (U712) is frequency shifted to avoid specific receiver
interference products. U711 and U712 are selected by the REF_SHIFT line, which controls the complementary
switch (Q711 and Q712). The outputs of U711 and U712 are connected to the PLL reference divider (U760) and to
the input of U701, a high frequency PLL, the output of which provides the DSP clock signal.
The carrier frequency adjustments for U711 and U712 are achieved by setting the ADJ voltage by using the
Alignment Tool. In addition, the ADJ input is used in a frequency control loop with the receiver I and Q signals, to
provide receiver AFC. The TCXOs are specified at ±1.5ppm frequency stability over the temperature range -30° to
+75°C.

DSP and PLA
3.4.1
The SRM9000 transceiver operates under the control of a DSP (U201) and PLA (U300) combination that, together
with a number of other dedicated devices, perform all the operational and processing functions required by the
radio. The PLA is configured by the DSP under software control to provide the following functions:

PLA PWM
The PLA must supply several analog signals to control radio tuning.
Modulated (PWM) outputs.
It does this with several Pulse Width
The front-end tune signals (TUNE1 and TUNE2) originate from the PLA in the form of PWM signals. The values
for these signals are stored in flash memory from radio alignment and are selected depending on the channel that
the radio is currently tuned to. The PWM signals are integrated by RC networks to provide the analog tuning
voltages for the varicap tuning diodes.
Other analog PWM derived signals used are transmitter power (TX_PWR), PLL varicap bias (VCAP_ADJ),
receiver IF gain (IF_GAIN), Automatic Frequency Control (AFC), AFC Switched (AFC_SW), VCO automatic level
control (VCO_ALC) and modulation balance (MOD_BAL).
Analog inputs are monitored by four comparators comprising U301A-D and a ramp generator, the ramp being
derived from a PWM signal from the PLA.
© TMC Radio 2008
page 29
TNM-M-E-0022 Issue 1
SRM9000X8 800MHz SERVICE MANUAL
Analog voltages to be monitored such as PLL Loop Voltage (LOOP_VOLTS), battery voltage (BAT_SENSE),
transmitter current (CURRENT_SENSE) and external sense (EXT_SENSE) are connected to the inverting inputs.
The analog voltages are compared with the ramp voltage as they increase, and the comparator switches at the
point where the input voltage exceeds the ramp. The PLA compares the time at which this occurs with the PWM
signal and converts it to a binary value.
3.5
MEMORY
Memory consists of the internal DSP memory and an external 8MB non-volatile Flash Memory (U202). When
power is off, all program SW and data are retained in Flash Memory. At power-on, a boot program downloads the
DSP and PLA SW from Flash Memory to their internal RAMs for faster program execution and access to data. PLA
SW is loaded by the factory into the Flash Memory and can be updated via the Alignment Tool. DSP SW
comprises Start-up code that is also loaded by the factory. High-level software comprising Operational Code and
Customer Configuration are loaded at distribution centres and are loaded via the FPP Programmer.

POWER SUPPLIES
3.6.1
Power On Function
The unregulated 13.8V DC input (13V8_UNSW_F) is routed directly to all high current devices and is then
switched via FET (Q900) to provide BAT_SW supply for all other circuits. The output from Q900 feeds three low
dropout series regulators and switched battery voltage. These regulated supplies power auxiliary supplies as well
as the negative and positive voltage generators. The radio ON/OFF function is achieved through Q902, Q908 and
Q909. A low voltage pulse from the control unit or microphone handset PWR ON or PWR OFF momentarily turns
on Q900/Q908 for approximately 1 sec. In this time, the radio DSP samples the PWR_SENSE line and determines
the state of the on-off switch. If the on-off switch is on, the DSP raises the PWR_OFF line and latches the main
FET (Q900) on, which then maintains power to the radio circuitry.
The Power-off operation requires the On-Off switch to be turned off for more than 2 seconds. If the On-Off switch
is sensed going low by the DSP via the PWR_SENSE line, the DSP will save radio settings and then lower the
PWR_OFF line, thereby turning Q900 off.

ALIGNMENT (LEVEL 3 SERVICE ONLY)
4.1
GENERAL
Caution
Preparing the radio for alignment will erase from the radio all customer PMR and Trunking
configuration data (channel, signalling information etc). The only data retained by the Alignment
Tool is the factory alignment data for the radio (DAC settings for Tx power, front-end tuning, etc).
Using the Alignment Tool will allow changes to the original factory alignment and will invalidate
all warranties and guarantees unless performed by an authorised level 3 service centre.
If the radio contains customer configuration data that must be retained, you must first use the SRM/SRP
Personality Programmer (FPP) software to read all radio configuration files and save them on to alternative media
before commencing the alignment procedure.
When the Alignment is completed, use the FPP software to retrieve the stored data and write it back to the radio.
It is preferred that the radio remain installed in its aluminium extruded case throughout this alignment procedure. If
the radio is to be aligned when removed from the case, a temporary heat sink must be fitted under the Transmitter
PA module and the receiver output must be kept below 100mW.
Note. Final Tx power adjustments must be performed with the radio board installed in the chassis.
Each transceiver will need to be individually tested and to have the resultant calibration data stored within it. This
data cannot be modified by the user or by the normal customisation (eg. channel frequency, selcall ID etc.)
process. It is set during the manufacturing process and may be modified for maintenance purposes by use of the
Alignment Tool.
For customer channels between each pair of test frequencies, an interpolation is automatically carried out to
determine the correct DAC values at the relevant frequency for the above calibration parameters.
For all of the following alignment procedures it is assumed that the radio is connected to a Comms. Analyser or
equivalent collection of test equipment. The alignment is performed at room temperature, with a 50Ω termination
on the antenna connector and with a power supply set to give 13.2V at the radio connector.
Warning
The RF power output from the transmitter during these tests can cause burns and can be dangerous to
some discrete items of test equipment, hence power attenuators may be needed. Also the heat generated
inside the radio after a long period of transmission can be hazardous.

Calibration sequence
On a set that has not previously been calibrated or in which the calibration has been corrupted, preset parameters
should be initially loaded into the radio for optimum alignment, after which the calibration steps must be carried out
in the following order. These preset parameters may be obtained by reading a previously aligned radio or by
loading predetermined default values.
A number of aspects of the radio need to have calibration data determined and stored during manufacture and
subsequently used by the S/W during normal operation. These must be aligned in the following order:
• Tx and Rx VCO
• TCXO’s
• Tx power
• VCO ALC
• Tx modulation (deviation and then mod balance)
• Rx and Tx filter tuning
• Rx mute
• RSSI
• Tx Current Limit

Note:
In test alignment mode the radio is configured only for 12.5 kHz channel spacing. Therefore all alignment
is carried out at 12.5 kHz levels. When the radio is configured with the FPP for other channel spacings,
the deviation related levels are calculated on a per channel basis by the radio software.
4.1.12
ALIGNMENT PROCEDURE
Radio alignment must be done in the sequence detailed in the following paragraphs. This alignment assumes that
the radio is functioning normally.
4.1.13
VCO DAC Alignment
The frequencies generated by the Tx and Rx VCO’s are determined by the synthesiser loop output for fine control
and by a DAC setting for coarse control. The DAC needs calibrating at each of four test frequencies. No calibration
is necessary for the receiver 2nd LO.
During this procedure, the alignment program puts the radio into a special mode in which it ignores the ‘out of
lock’ signal from the synthesiser.

Tx Power DAC Alignment
4.1.19
General
The transmitter output power can be programmed to three power ranges: 1W, 5W and 27.5W by the
appropriate setting.
Note 1: Care should be taken not to set the output power and hence supply current to excessive levels, ie.
above 30W or 7.5A, since the higher heat dissipation involved may effect component reliability.
Note 2: Also, the antenna connector should be terminated directly into the Comms. Analyser for this test to
minimise VSWR effects that could affect settings.
Note 2: Repeat the following steps as quickly as possible to avoid excessive heating the radio, which may
affect calibration.
Note 3: The Tx Current Limit setting provides a maximum current limit into the RF PA module to protect it in
the event of high dissipation as a result of inadequate drive power being applied relative to the Power DAC
setting or high VSWR’s
Calibration procedure

Tx Modulation DAC Alignment
All microphone levels are referenced to the audio level output displayed on the Comms. Analyser and based on <10Ω
source impedance.
NOTE: This audio signal is fed to the radio input via a series 470Ω resistor and 47uF capacitor in the Audio/ Serial
Interface Adaptor.
General
Dual point modulation is used and there are two settings that need adjusting to meet deviation requirements. The
modulation alignment is set up for 12.5kHz channel spacing. For customer configurations of other channel
spacings, the modulation alignment is automatically adjusted for those settings.
Note that when measuring deviation at 60% MSD the average of the + and − readings should be used. When
measuring maximum deviation, the higher of the + and – readings should be used.

APPENDIX A - GLOSSARY OF TERMS
A summary of common radio terms and some other terms used in this document, and their meanings, are given
below.
ADC
Analog to Digital Converter.
AFC
Automatic Frequency Control.
AGC
Automatic Gain Control.
Alarm
A Selcall sequence sent from subscriber equipment to indicate an Emergency situation.
When activated the radio will enter a repeating sequence consisting of an Alarm Live
Transmit Time and an Alarm Dead Receive Time.
Certain special conditions for the radio may also occur during the alarm.
A dedicated SFM (trunked system) that is sent by pressing the Alarm Key.
ANI
Automatic Number Identification.
Auto Interrogate
An Acknowledge identity sent as a response to an individual reset call.
Automatic Power
Feature whereby the transmit power is automatically set to a level determined by the
level of the received signal. This is used to extend the battery life and/or reduce radiated
emissions.
Automatic Volume
Feature whereby the background audio level is monitored and if this is found to be noisy
then the volume level is increased to compensate, allowing the user to hear better.
Busy
The state of a channel such that:
•
For a non-signalling channel - if Busy this means that the carrier is above squelch.
•
For a channel with CTCSS/DCS - if Busy this means a signal is being received with
either no CTCSS tone / DCS code or the correct CTCSS tone /DCS code.
•
For a channel with Selcall - if Busy this means a closed channel where the signal is
above squelch.
A feature that equates to 'Do Not Disturb' such that the radio will reject all nonemergency calls. This feature can be activated using the Busy key (if assigned) or from a
menu; it is reset to disabled at switch on.
C4FM
Compatible 4-Level Frequency Modulation.
Call Back
A request, sent by the dispatcher, to a unit requesting that the unit calls the dispatcher
back.
Channel Spacing
The distance (in kHz) between the defined frequency channels.
Clipboard
A temporary storage area in Windows used to store data in cut, copy and paste
operations.
Closed
A state where transmit and receive are not allowed until a Selcall message to open the
channel has been received. A Closed Channel is one which defaults (when selected or
after timed reset) to its closed state. Contrast with Open. Normally a Closed channel
would have Selcall Mute and PTT Inhibit would be enabled.
CODEC
COde (Analog to Digital Converter) / DECode (Digital to Analog Converter).

Community Repeater
A communications set-up whereby different groups of radios can operate by using only
one base station. This is achieved by the use of CTCSS tone signalling such that each
group has a different CTCSS tone (encode and decode) and radios can only
communicate with other radios in their group. Only one group of radios can use the base
station at any one time.
CRU
Central Repair Unit
CTCSS
CTCSS stands for Continuous Tone Controlled Signalling System. A continuous tone
(lower than the audio range of the receiver) is modulated onto the carrier as well as other
signalling or voice traffic. Compare with DCS. Only receivers that have been instructed to
recognise the same CTCSS tone are able to receive the transmissions, since the squelch
of receivers looking for different CTCSS tones prevents the audio from being heard. This
provides a simple method of sending messages to selected receivers only and allows
several different networks to use the same frequencies. CTCSS is also known as Tone
Lock or Tone Squelch.
DAC
Digital to Analog Converter.
Dash (-) digits
Digits known as 'No Tone' digits used in Selcall Identities.
DCS
Digital Coded Squelch system is based on sending a continuous stream of binary code
words using, low deviation, direct frequency shift keying. Only receivers that have been
instructed to recognise the same DCS sequence are able to open their squelch and
receive the associated speech transmissions. This provides a simple method of sending
messages to selected receivers only and allows several different networks to use the
same frequencies.
Decode
Reception of signalling. Either Selcall where encoded tone frequencies are decoded and
identified as specific tones digits or CTCSS/DCS where tones are analysed to see if the
channel should be opened.
Disabled
The 'False' state of a parameter. That indicates this parameter is not active. Typically this
state is represented by an unmarked check box. Compare with Enabled.
DSP
Digital Signal Processor.
DTMF
Abbreviation of Dual Tone Multi-Frequency signalling. Used to dial into Telephone
networks using tone dialling.
Dual Watch
A facility that enables the Radio to periodically monitor another channel for a signal
above squelch. Typically applications are checking an emergency channel whilst on
another channel.
Economiser
A process by which the Receiver is powered down whilst there is no received signal.
Periodically the receiver is powered up to check for such a signal. This is used to extend
the battery life.
Enabled
The 'True' state of a parameter. That indicates this parameter is active. Typically this
state is represented by a mark (either a tick or a cross) in a check box. Compare with
Disabled.
Encode
Transmission of signalling. Either Selcall where Selcall tone digits are encoded into tone
frequencies or CTCSS/DCS where tones modulated onto the channel's carrier.
External Alert
A facility for switching on various ancillary devices to meet customer's individual
requirements (e.g. car horn, flashing lamp etc.) when 'called'.
Only available on a mobile radio. To make available: go to Hardware Components,
Terminal Settings and set Product Type to a Mobile type.
Fallback
A mode of operation that may be entered when the Network is suffering a malfunction.
During this mode certain facilities (e.g. PSTN) may not be available.

FFSK
Fast Frequency Shift Keying. This is a signalling system for the transfer of digital
information. It works by using one of two audio tones to represent transmit data..
Fleet
A group of units formed such that only a shortened form of dialling (2 or 3 digits) is
required between them. These groups are normally assigned contiguous ident's.
PLA
Programmable Logic Array.
FPP
Field Personality Programmer.
Hash (#) digits
These digits are used for two purposes:
• For Selcall identities (encode and decode) - known as User Id digits. These digits are
replaced by the user id entered at switch on (if enabled)
• Use in DTMF dialled strings - their use is network dependent to access special services.
Identity
Name given to a sequence of tones which is used in sequential tone signalling. See Valid
Selcall Digits.
Idle State
The state of the radio when it is not in a call.
Inaccessible
A state of a channel such that it is unavailable to the user through normal methods of
channel selection. Therefore inaccessible channels will not appear on the channel menu.
Link Establishment
Time
A delay incorporated into the start of every selective call or DTMF transmission
which allows for the finite delay of the radio equipment in responding to any radio signal.
This includes both the commencement time of the originating transmitter and the
response time of the receiver.
Locked
A state of a channel whereby it is not possible to change channels using the normal
up/down keys on the channel menu until the OK key is pressed. See Auto Channel
Selection Lock.
Null Id
A Selcall identity that is not defined and whose tones' field is displayed as a blank.
Open
A state where transmit and receive are allowed. The channel is no longer open when
reset. Contrast with Closed.
Normally an Open channel would not have Selcall Mute and PTT Inhibit would be
disabled.
PABX
Password
Private Automatic Branch Exchange.
An optional password system available on the radio. This feature is only available if the
radio has a display and a keypad. To make available: go to Hardware Components,
Terminal Settings and set Product Type to one which has a display and a keypad.
PLL
Phased Locked Loop.
PMR
Private Mobile Radio (not normally trunked).
Priority Channel
A channel in a search group that is scanned between every other channel.
PSD
Peak System Deviation.
PSTN
Public Switched Telephone Network.
PTT
Press To Talk. This is the term given to the operator’s key normally used to commence
transmitting a message.
PTT Inhibit
A state whereby transmission using the PTT is not allowed. Also know as Tx Lockout.
PWM
Pulse Width Modulation.

Reference Frequency
Normally this is generated from a high stability crystal oscillator reference and is divided
digitally in a frequency synthesiser for comparison with other frequency sources, e.g. a
VCO.
Repeat Tone
A selcall tone that is used to replace repeated tones. Fixed at tone E.
Example: An identity entered as '12333' would be sent by the radio as '123E3'.
Resetting is caused by Three Tone Reset, a Remote Reset, an Individual reset or a
Group reset (Call Types in Decode Identity). When a radio is reset the effect on the radio
will be as follows:
Reset
• Any Call Alerts will be stopped
• The Call LED flashing will stop
• If the channel is in Open mode then the channel is closed
• The PTT is optionally inhibited see PTT Inhibit After Reset Sequence.
• In searching - if paused on a selcall channel then searching resumes
• If the Acknowledge property of a Decode Identity is set to 'Auto Interrogate' or
'Transpond & Auto Interrogate' then the Auto Interrogate encode identity is transmitted.
RSSI
Received Signal Strength Indicator.
Scanning
Process of switching between the channels in the nominated search group in cyclic
sequence, stopping when the search condition (which may be to look for either a free or
a busy channel) is satisfied.
Search Group
A group of channels that are either scanned for a signal above the search threshold or
are compared and voted for the strongest signal
Selcall
Selective Calling - a system of signalling which allows 'dialling up' of specific mobiles,
portables and controllers. Such a system may be used to pass messages as a data
message to a specific user or group of users. It can be used to provide remote switching
facilities and to provide access control into community repeaters or similar devices.
Selcall Mute
A state of the audio gate whereby the loudspeaker is muted (closed).
Selcall System
Selective Calling, uses a tone sequence at the start, and end, of a call to control which
members of a fleet react to the transmission.
Sidetone
Sidetone is the audio which can be (optionally) heard when Selcall, DTMF and toneburst
transmissions are made.
Simplex
Mode of operation whereby the radio operates as a conventional fixed channel radio
outside the Trunking network.
Squelch
System used to prevent weak, unintelligible signals and random noise from being heard
by a radio operator while still allowing intelligible signals to be received normally. This is
accomplished by the use of a threshold below which any received signals are ignored.
Only signals whose signal-to-noise ratio is above the squelch level cause the audio
circuits of the radio to be enabled, with the result that only satisfactory signals are
received. The squelch level is specified in SINAD.
Star (*) digits
Digits known as Status or Message digits. These digits are used for three purposes:
• Status Digits for Selcall Identities
• Wildcard digits in Status strings
• Use in DTMF dialled strings - their use is network dependent to access special services.
Status
© TMC Radio 2008
A feature whereby a radio's status (or usually the status of the radio's user) can be
transmitted and a status message from other radios can be displayed. This operates
page 71
TNM-M-E-0022 Issue 1
SRM9000X8 800MHz SERVICE MANUAL
through status digits in Selcall identities. Either in Encode Identities or Decode Identities
as follows:
Encode Identities: Status digits within the identity are used to transmit the current
situation of the radio's user (e.g. "Out To Lunch").
Decode Identities: Status digits are looked up in a table (Status Menu) for possible
messages to display.
SW
Software.
TCXO
Temperature Compensated Crystal Oscillator.
Three Tone Reset
This is a system whereby a call to a user automatically reset all other users in a group.
Example: a call to user '12345' would call 12345 and reset all other users on this channel
with an identity 123nn where n can be any digit 0-9, A-F.
Tone Burst
An audio tone is transmitted at the start of transmission to inform a relay (repeater)
station to switch itself on to relay the transmission.
Transpond
An Acknowledge identity sent as a response to an individual call.
Tx Inhibit
A facility which prevents the user from transmitting,(other than alarms), while the channel
is Busy.
User Identity
This is a sequence of up to four digits entered by the user when the Radio is switched
on, if this option is programmed. These digits are then substituted into any transmitted
Selcall identity which includes # digits.
VCO
Voltage Controlled Oscillator.
Vote
Method used to compare the signal strength on a current channel with another specified
channel and then to choose the channel having the stronger signal.
Voting
Feature used during searching when there is more than one channel that satisfies the
required conditions. It involves examining all the channels that satisfy the required
conditions, and then selecting the channel with the highest signal strength.
VOX
Voice Operated Transmit.
