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). 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.

Warnings and Cautions
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 1 TNM-M-E-0022 Issue 1 1. 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 high-impact 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 © TMC Radio 2008 page 4 TNM-M-E-0022 Issue 1 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. 1.4.1 Filename Structure 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 1.4.2 Application Code This identifies the application the SW was initially designed for: 9e Standard SRM9000 Rev 9 Software ae SRM9000 Rev 9 Software applicable for SRP9022 1.4.3 Software Type Code This identifies different types of SW within an application. s_ Startup p_ Standard PMR.

The above file names are not stored within the code. As a consequence, when the radio is read by the FPP, the FPP will display version numbers and release dates for the Backup, Startup, PMR and DMAP codes. The Bootloader, PLA Backup and PLA codes show release dates only.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 6 TNM-M-E-0022 Issue 1 1.4.4 Version Number This is a 3-digit number allocated by Engineering to identify the SW version. e.g. 103 = Version 1.03 1.4.5 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
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 7 TNM-M-E-0022 Issue 1 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 © TMC Radio 2008 page 8 TNM-M-E-0022 Issue 1 1.4.8 Transceiver SW Description, Start-up and Backup-Software 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 Start-Up 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: • 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.) 1.4.9 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: 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. 1.5 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 9 TNM-M-E-0022 Issue 1 1.6 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.

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 21 TNM-M-E-0022 Issue 1 3. TECHNICAL DESCRIPTION 3.1 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.

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 23 TNM-M-E-0022 Issue 1 3.1.4 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 24 TNM-M-E-0022 Issue 1 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 non-inverting 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).

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 26 TNM-M-E-0022 Issue 1 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 27 TNM-M-E-0022 Issue 1 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.

The PLA is configured by the DSP under software control to provide the following functions: • Channel set-up of all operating frequencies • Modulation processing and filtering • De-modulation processing and filtering • Tx power output reference • Modulation Balance adjustment • Receiver front-end tuning • Serial communications with alignment tool, microphone and control head • Modem functionality for data modulation • All signalling / CTCSS generation and decoding • Receiver muting control • TCXO/ Alternate TCXO select • RSSI / AGC control • AFC • Tx / Rx switching and PTT control • PLL lock detect • Audio switching • Power On/Off control • Interface functionality with Option Boards and External Devices • Battery voltage and Tx current monitor 3.4.2 PLA PWM The PLA must supply several analog signals to control radio tuning. It does this with several Pulse Width Modulated (PWM) outputs. 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 30 TNM-M-E-0022 Issue 1 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.

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 32 TNM-M-E-0022 Issue 1 3.6 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. 3.6.2 Power Supplies The following is a list of the SRM9000 power supplies and some of the devices and circuits they supply. 3.6.2.1 8V Regulator U900 Regulated 8.0V supply (8V RF) • Tx buffers Q521, Q531a • VCOs and VCO buffers via active filter Q622 Regulated 8.0V switched supply (5V RX) • Rx front end • IF Amplifier • Various switching functions 3.6.2.2 5V Regulator U901 Regulated 5.0V supply (5V A, 5V D, 5V RF and 5V RFF) • Synthesizer buffer Q640 • VCO varactor positive supply Q780 to Q783 • TCXOs U711 and U712 • TCXO divider U760 • Rx audio amplifiers U802/U803 • Rx mute switch Q810 to Q813 Regulated 5.0V switched supply (5V TX and Tx PSU+) • Tx power control U551 • Tx buffers Q501 to Q531a • Various switching functions 3.6.2.3 3.3V Regulator U912 Regulated 3.3V supply (3V3) • Reset U200

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 34 TNM-M-E-0022 Issue 1 4. ALIGNMENT (LEVEL 3 SERVICE ONLY) 4.1 GENERAL 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. 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 35 TNM-M-E-0022 Issue 1 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 4.1.1 Test Equipment 1 Radio transceiver test set CMS-50 Comms.

Choose No if you want to save the configuration and use the FPP software to read and save the data to a file. Choose Yes if you want to proceed and go to step 3. 3 The radio alignment data is read (indicated by percentage bar) and stored. The test alignment data is downloaded into the radio. 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.

The Synth DAC Tx slider will automatically adjust its value for each transmitter alignment frequency to set the VCO loop filter value between 87 and 93. 4 The Synth DAC Rx slider must be set to the same Tx value for Channels 0 and 1 only. This is automatically set when Auto Align is selected.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 45 TNM-M-E-0022 Issue 1 4.1.14 TCXO DAC Alignment General The optimum radio case temperature for TCXO alignment is around 25°C although a temperature between 20°C and 30°C is permissible. If the radio has been allowed to exceed this range during previous transmit cycles, it should be allowed to cool until it is within the permissible range. Calibration procedure 1 Select the Mute/TCXO page. 2 Select PTT. 3 Adjust the TCXO slider to ensure that the transmit frequency error is within 50Hz of 824.925000MHz. 4 Select “Set Alternate TCXO”. 5 Adjust the TCXO slider to ensure that the transmit frequency error is within 50Hz of 824.912500MHz. 6 Deselect “Set Alternate TCXO”. 7 Deselect PTT.

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 49 TNM-M-E-0022 Issue 1 4.1.18 Mute DAC Adjustment Note. This adjustment has default setting of 1000/2600 and should not need changing except for specific requirements. Calibration procedure 1 Select the Mute/TCXO page and select Open Mute. 2 Set the RF signal generator to the receiver alignment frequency, and adjust the RF level such that the desired mute opening SINAD (typically 10dB SINAD) is achieved. 3 Select Close Mute and remove the RF input from the radio. 4 Set the Squelch Open and Squelch Close sliders to the fully left position. This ensures the receiver will be muted. 5 Set the Squelch Close slider to the fully right position. 6 Reconnect the RF input to the radio. 7 Adjust the Squelch Open slider to the right until the mute opens. 8 Reduce the Signal Generator output level by approximately 2dB (or by an amount equal to the desired mute hysteresis level). 9 Adjust the Squelch Close slider to the left until the mute closes. 10 The mute should now open and close at the desired RF levels.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 50 TNM-M-E-0022 Issue 1 4.1.19 Tx Power DAC Alignment 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 1 Select Tx Power/Mod page. 2 Select Channel 0. 3 Select the 1W power level. 4 Press the PTT button. 5 Adjust the Tx Final Value slider for a power output of 1W. 6 Repeat step 5 for the remaining 3 Channels (1, 2, & 3).
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 51 TNM-M-E-0022 Issue 1 7 Select the 5W power level. 8 Adjust the Tx Final Value slider for a power output of 5W. 9 Repeat step 8 for the remaining 3 Channels (2, 1& 0). 10 Select the 27.5W power level. 11 Adjust the Tx Final Value slider for a power output of 27.5W. Note that the supply current is less than 7.5A. 12 Repeat step 11 for the remaining 3 Channels (1, 2, & 3). 13 Press Calibrate TX PA Current button and follow the prompt to automatically set the maximum current limit. 14 The PTT will automatically dekey after this procedure. 4.1.18 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 52 TNM-M-E-0022 Issue 1 Calibration procedure 1 Select Tx Power/Mod page. 2 Select Channel 0. 3 Select the 1W power level. 4 Set the microphone input signal from the Audio Generator to 1000Hz at 400 mV RMS. 5 Select PTT and adjust the VCO Modulation Limit DAC to give a maximum peak deviation of 2.30kHz. 6 Reduce the microphone input level to 40mV RMS and check that the deviation is within the range ±1.25 kHz to ±1.75 kHz. 7 Repeat steps 5 to 6 inclusive for the remaining three Channels (1, 2, & 3). 8 Remove the microphone audio input signal 9 Select the Generate Square Wave function. 10 While viewing the de-modulated signal on the transceiver test set oscilloscope, set to DC coupling, adjust the Modulation Balance slider for the best square wave symmetry. Refer to Note below 11 Repeat steps 9 to 10 inclusive for the remaining three Channels (2, 1 & 0). 12 Release the PTT button. Note: The FM demodulator on the measuring equipment also requires DC coupling for this test to provide correct results. If an HP8920A is used, the top and bottom of the square wave must be set with a 16.6% negative slope. ie. For a waveform of 4 divisions p-p (neglecting overshoot) the slope should be adjusted to 0.3 divisions.

SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 68 TNM-M-E-0022 Issue 1 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 non-emergency 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).
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 69 TNM-M-E-0022 Issue 1 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 70 TNM-M-E-0022 Issue 1 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 A delay incorporated into the start of every selective call or DTMF transmission Time 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 Private Automatic Branch Exchange. Password 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.
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 71 TNM-M-E-0022 Issue 1 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'. Reset 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: • 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 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
SRM9000X8 800MHz SERVICE MANUAL © TMC Radio 2008 page 72 TNM-M-E-0022 Issue 1 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.
