M850-00T856/857 General InformationC1.7Copyright TEL 31/09/981.1 IntroductionThe T856 is a synthesised, microprocessor controlled FM base station transmitterdesigned for single or multichannel operation in the 400 to 520MHz frequency range1with a standard power output of 25W.  The RF section of the transmitter comprises a fre-quency synthesiser which provides 100mW of frequency modulated RF drive to a twostage, wide band output driver followed by a 25W power amplifier.  A thermal shut-down feature is provided in the T856 in case operating temperatures exceed acceptablelevels.The T857 is a synthesised, microprocessor controlled FM base station exciter designedfor single or multichannel operation in the 400 to 520MHz frequency range1.  With astandard power output of only 1W, the exciter is designed for use with the T858 50W orT859 100W power amplifiers.  The RF section of the exciter comprises a frequency syn-thesiser which provides 100mW of frequency modulated RF drive to a two stage, wideband output amplifier.A wide selection of audio characteristics may be obtained from the audio processor.Optional circuit blocks are an audio compressor and a pre-emphasis stage.  They can bebypassed or linked to one or both audio inputs, and then back into the remaining audiocircuitry in almost any combination.  All audio processor options are link selectable.The synthesiser frequency is programmed via the serial communications port. Eightchannel select lines are accessible via an optional D-range connector (D-range 2 -T800-03-0000) at the rear of the set.All components except those of the VCO are mounted on a single PCB.  This is securedto a die-cast chassis which is divided into compartments to individually shield each sec-tion of circuitry.  Access to both sides of the main circuit board is obtained by removingeach of the chassis lids. There is provision within the chassis to mount small optionPCBs.The front panel controls include line sensitivity, microphone socket and carrier switch.This switch turns on the carrier (unmodulated) as an aid to servicing.The T856 and T857 are both 60mm wide and each occupies a single space in a Tait rackframe, which has the ability to accommodate up to seven standard modules.1. Although capable of operating over the 400-520MHz frequency range, the T856 and T857 have an 8MHz switching range (see Section 1.2.3 and Section 3.1).

It runs from internal ROM and RAM, thusleaving all four ports free for input/output functions.Non-volatile data storage is achieved by serial communication with a 16kBit EEPROM(IC820).  This serial bus is also used by the microcontroller to program the synthesiser(IC740) and deviation control EPOTS (IC220).The main tasks of the microcontroller are as follows:• program the synthesiser and EPOT;• interface with the PGM800Win programming software at 9600 baud via theserial communication lines on D-range 1 (PL100) & D-range 2;• monitor channel change inputs from D-range 2;• generate timing waveforms for CTCSS encoding;• coordinate and implement timing control of the exciter/transmitter.5V Reset5V DigitalRegulator Watchdog ResetChannelSelectPortAuxiliaryOutputPortMicrocontroller12.8MHzClockMicrocontroller CavityCTCSS ToneExternalSerialPortEEPROM SynthesiserDual DigitalPotentiometerCTCSSEncoderConverter

The synthesiser receives the dividerinformation from the control microprocessor via a 3 wire serial bus (clock, data, enable).When the data has been latched in, the synthesiser processes the incoming signals fromthe VCO buffer (fin) and the phase modulator (fref).A reference oscillator at 12.8MHz (=IC700) is buffered (IC710 pins 3 & 4) and divideddown to 200kHz (IC730).  This 200kHz square wave is then summed with the modulat-ing audio and passed to an integrator (IC720 pins 9 & 8, Q710, Q720).  This produces aramping waveform which is centred around a DC level determined by the incomingaudio.  IC720 pins 5 & 6 perform as a comparator, ultimately producing a phase-modu-lated 200kHz square wave.  This is followed by another phase shifting stage (IC720 pins3 & 4, Q730, Q740), before being divided down to 6.25kHz or 5kHz within the synthe-siser IC (IC740).A buffered output of the VCO (Q795) is divided with a prescaler and programmabledivider which is incorporated into the synthesiser chip (IC740).  This signal is comparedwith the phase modulated reference signal at the phase detector (also part of the synthe-siser chip).  The phase detector outputs drive a balanced charge pump circuit (Q760,Q770, Q775, Q780, Q785) and active loop filter (IC750 pins 5, 6 & 7, Q790) which pro-duces a DC voltage between 0V and 20V to tune the VCO.  This VCO control line is fur-ther filtered to attenuate noise and other spurious signals.  Note that the VCO frequencyincreases with increasing control voltage.If the synthesiser loop loses lock, a pulsed signal appears at LD (pin 2) of IC740. Thissignal is filtered and buffered by IC750 pins 1, 2 & 3, producing the Lock-Detect signalused to shut off the power supply to the drive amplifier.  IC750 pin 1 is at 20V when thesynthesiser is out of lock./RReferenceDivider12.8MHzReferenceOscillator FixedDivider/64PhaseModulatorRefModPhaseDetector ChargePump LoopFilterFREQUENCY SYNTHESISER ICSerialBusClkDataEn Controller/NProgrammableDivider64/65PrescalerVCO PCBVCO ModulationVCO Buffer OutputBuffer+22dBmL.O.Divider BufferfreffinΣ
C2.6T856/857 Circuit OperationM850-0031/09/98 Copyright TEL2.3.1 Two Point ModulationFrequency modulation occurs by modulating both the VCO input and the synthesiserreference input.  This process is called two point modulation and ensures a flat modula-tion response from 67Hz to 3kHz (2.55kHz for narrow bandwidth).The PLL has a fast response time, allowing a Tx key-up time of <30ms.  Because of thisfast response time the PLL sees lower modulation frequencies superimposed on theVCO as an error and corrects for it, resulting in no modulation on the carrier.  At modu-lation frequencies greater than 300Hz the loop cannot correct fast enough and modula-tion is seen on the carrier.  The response of the loop to VCO modulation is shown by f2in Figure 2.5 below.To achieve low frequency modulation, the reference oscillator is also modulated so thatthe phase detector of IC740 detects no frequency error under modulation.  Thus, thesynthesiser loop will not attempt to correct for modulation and the audio frequencyresponse of the transmitter remains unaffected.  The response of the loop to referencefrequency modulation is shown by f1 in Figure 2.5.Figure 2.5   T856/857 Two Point Modulation
M850-00T856/857 Circuit OperationC2.7Copyright TEL 31/09/982.4 VCO(Refer to the VCO circuit diagram in Part E.)The VCO transistor (Q1) operates in a common emitter configuration, with an LC tankcircuit coupled between its gate and drain to provide the feedback necessary for oscilla-tion.  The VCO control voltage from the loop filter (IC750) is applied to the varicaps(D1-D2) to facilitate tuning within an 8MHz band of frequencies.  A trimcap (C6) is usedfor coarse tuning of the VCO.  The output from the oscillator circuit drives a cascodeamplifier stage (Q2, Q3) which supplies +10dBm (typically) to a further stage of amplifi-cation, Q5.  This is the final amplifier on the VCO PCB, and delivers +20dBm (typically)to the exciter drive amplifier.A low level "sniff" is taken from the input to Q5 and used to drive the divider buffer forthe synthesiser (IC740).The VCO operates at the actual output frequency of the exciter, i.e. there are no multi-plier stages.  It is modulated by superimposing the audio signal onto the control voltageand by phase modulating the reference signal.2.4.1 VCO Supply The VCO is supplied from two switched +9V supplies under the control of the Tx-Reg.supply.The VCO and buffer amplifier are supplied from one +9V switched supply by Q540 viathe C multiplier (Q550, C530 on the T856 and C550 on the T857).The output amplifier is supplied from the other +9V supply by Q520, Q530, and Q510.A delay circuit holds the VCO on for a short time after the Tx-Reg. supply has beenswitched off.  This is to allow the RF power  circuits (both exciter and PA) to ramp downin the correct manner before the VCO is switched off.

This features a constant current sink (Q270) to ensure reli-able activation of the opto-coupler (IC250) at low keying voltages.2.5.4 Compressor (Automatic Level Control (ALC))The input signal is fed via a current controlled attenuator (Q230, Q220) to a high gainstage (IC230) from which the output signal is taken.  This signal is passed to a compara-tor (IC230) which toggles whenever the audio signal exceeds a DC threshold deter-mined by RV220.  Thus, the comparator produces a square wave whose mark-spaceratio is determined by the amplitude of the audio signal.  This square wave pumps upthe reservoir capacitor (C233) which controls the attenuator (Q230, Q220), thus complet-ing the feedback loop.The compression level is set by adjustment of the comparator threshold (RV220).Note:Although the high dynamic range of the compressor allows the use of verylow audio signal levels, such conditions will be accompanied by a degrada-tion of the signal-to-noise ratio.  Very low audio input levels should there-fore be avoided where possible.2.5.5 Outputs To ModulatorsThe output signal from the limiter (IC210, IC230) is summed with a CTCSS tone at asumming amplifier (IC260).  The signal is then low pass filtered (IC260) and split to sup-ply the two modulators.Since the VCO modulator is a true frequency modulator, its audio is simply buffered(IC260).  The reference modulator, however, is a phase modulator and its audio mustfirst be integrated (IC210).It is vital that the audio levels to the modulators are accurately set, relative to eachother.  Hence the inclusion of level adjustment in the reference modulator path.  Onceset, adjustments to absolute deviation may be made only via the deviation digital pot.(IC220 - adjustable via PGM800Win).

The forward andreverse RF power levels are sensed via a dual directional coupler and detector diodes(D440, D420 in the PA cavity).  The detected DC signals are buffered (IC330 pins 3 & 5)and then summed with the ’power control’ level and fed to the control integrator (IC350pin 6).  The output control voltage is buffered by Q310 and Q315, and applied to the col-lector of the wide band exciter amplifier.Note:Forward and reflected power signals are summed so that, under highVSWR, the power control will turn the output RF level down. To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. andLock-Detect signals are gated to inhibit the PA control circuit and to switch off the RFsignal at the input to the drive amplifier.  This is achieved by a PIN switch attenuator(D340, D380, D360).Cyclic keying control is provided by additional circuitry consisting of several timedelay, ramp and gate stages:• Q325, IC350 power ramping• Q355, Q325 Tx-Reg. and Lock-Detect gate• Q335, Q340, Q345 delay and PIN switch drive.This is to allow the RF power circuits (both exciter and PA) to ramp up and down in acontrolled manner so that minimal adjacent channel interference is generated duringthe transition.The output of the wide band amplifier is approximately 1W (+30dBm) for an input of100mW (+20dBm) from the VCO, when the power control is set to maximum.A temperature sensor (R481) is provided so that the RF output power can be reduced toa preset level when a set temperature is exceeded.  This is a protection circuit (IC350 pin1, Q320) to prevent overheating, as the unit is not rated for continuous operation (referto Section 1.2.3 for duty cycle specifications).#R517, #R518 and #R519 form an attenuator to provide good VCO/exciter isolation aswell as the correct exciter drive level.The attenuator (#R395, #R396 and #R397) aids in producing the correct exciter drivelevel to the PA over the three frequency ranges.The RF output from the exciter is fed to the driver stage (Q410) and then to the final(Q420).  DC is fed to the final via a low pass filter with special low frequency decou-pling.  CV475 tunes the output matching across the entire band.

M850-00T856/857 Initial Tuning & AdjustmentC3.3Copyright TEL 31/09/983.1 IntroductionWhen you receive your T856 transmitter or T857 exciter it will be run up and workingon a particular frequency (the "default channel")1.  If you want to switch to a frequencythat is within the 8MHz switching range (i.e. ±4MHz from the factory programmed fre-quency), you should only need to reprogram the transmitter/exciter with thePGM800Win software (refer to the PGM800Win programming kit and Section 3.2below).  However, if you want to switch to a frequency outside the 8MHz switching range, youwill have to reprogram and re-tune the transmitter/exciter to ensure correct operation.In this case you should carry out the short tuning procedure described in Section 3.4.If you have carried out repairs or other major adjustments, you must carry out the fulltuning and adjustment procedure described in this section (except for Section 3.4).  3.2 Channel ProgrammingYou can program up to 128 channel frequencies into the transmitter/exciter’s EEPROMmemory (IC820) by using the PGM800Win software package and an IBM PC.  You canalso use PGM800Win to select the transmitter/exciter’s current operating frequency (or"default channel").If the transmitter/exciter is installed in a rack frame, you can program it via the pro-gramming port in the speaker panel.  However, you can also program the transmitter/exciter before it is installed in a rack frame as follows:• by using a T800-01-0010 calibration test unit;• via D-range 1;• via D-range 2 (standard T800-03-0000 auxiliary D-range only);• via SK805 (internal Micromatch connector).If you do not use the T800-01-0010, you will have to connect the PC to the transmitter/exciter via a module programming interface (such as the T800-01-0004).For a full description of the channel programming procedure, refer to the PGM800Winprogramming software user’s manual.Note:When an auxiliary D-range kit (D-range 2 - T800-03-0000) is fitted, you canalso select a channel with an external switch, such as the DIP switch on therack frame backplane PCB.  Refer to Part C in the T800 Series AncillaryEquipment Service Manual (M800-00-101 or later issue) or consult yournearest Tait Dealer or Customer Service Organisation for further details.1. Use the "Read Module" function in PGM800Win to find out what the default channel is.

Electronic potentiometers (256 step) are used to allow chan-nel-by-channel adjustment of deviation and two point modulation.Note 3:To optimise the modulation response across the switching range, repeatsteps 1-4 below for each channel that will be used (usually needed only fordata applications).  In applications where the modulation response is lesscritical (e.g. voice use only), carry out steps 1-4 below on the middle channeland cut and paste the value to all other channels.1.

This is achieved by simultaneouslyfrequency modulating the VCO and phase modulating the synthesiser reference fre-quency.  The relative signal levels fed to the two modulators are quite critical and causeinteraction when setting up.Both modulating signals require readjustment when the exciter is shifted in frequencygreater than the switching range (i.e. ∆F>±4MHz).Note 1:In this and following sections deviation settings are given first for widebandwidth sets, followed by settings in brackets for mid bandwidth sets (  )and narrow bandwidth sets [  ].Note 2:Reference modulation and limiter adjustment are controlled byPGM800Win.

If repair or replacement is considered necessary, referto Section 3 of Part A.5.2 Component ChecksIf you suspect a transistor is faulty, you can assess its performance by measuring the for-ward and reverse resistance of the junctions.  Unless the device is completely desol-dered, first make sure that the transistor is not shunted by some circuit resistance.  Use agood quality EVM (e.g. Fluke 75) for taking the measurements (or a 20k ohm/V or bet-ter multimeter, using only the medium or low resistance ranges).The collector current drawn by multi-junction transistors is a further guide to their per-formance.If an IC is suspect, the most reliable check is to measure the DC operating voltages.  Dueto the catastrophic nature of most IC failures, the pin voltages will usually be markedlydifferent from the recommended values in the presence of a fault.  The recommendedvalues can be obtained from either the circuit diagram or the component data catalogue.5.3 Front Panel LED IndicatorThe green "Supply" LED on the T856/857 front panel will flash according to the condi-tions described in the following table:Where two or more conditions occur at the same time, the precedence is in the ordershown above (i.e. T856/857 linked has the highest priority, followed by internal error).Flash Rate Conditionfast (  sec. on/  sec. off approx.)

M850-00T856/857 Fault FindingC5.19Copyright TEL 31/09/985.8 To Replace The T856 PA Transistors(Q410 & Q420)Caution:Failure to comply with the following procedure can result in failure ofthe device due to poor heatsinking, or worse, can endanger the healthof the assembler if the beryllium oxide die carrier is smashed duringassembly.Caution:As the location of certain components in the PA is critical to perform-ance, it is important that any components removed or disturbed arerefitted in exactly the same position.Before attempting to remove a transistor, measure the distancebetween the capacitors and transistor body to the nearest 0.5mm (meas-urement "A" in Figure 5.2) so that the capacitors can be replaced inexactly the same position.  These measurements are shown in Figure5.2 for the 6LFL package, however the same procedure applies for theSOE (stud) package.Caution:Do not apply too much heat or pressure to the PCB pads and tracks asyou may damage them or lift them from the PCB, causing permanentdamage to the transmitter.Figure 5.2   Typical Transistor/Capacitor Spacing (Not To Scale)Desolder and remove the components from around the transistor.Q420 Only: Desolder and remove the two solder tags.Desolder the transistor tabs by heating with a soldering iron and lifting awayfrom the PCB with a screwdriver or thin stainless steel spike, then remove thedevice.           base collectormeasurement A
C5.20T856/857 Fault FindingM850-0031/01/99 Copyright TELQ410 Only: Unscrew the transistor stud nut and remove the device.Remove any excess solder from the PCB pads with solder wick.Trim the tabs of the replacement transistor so that the device sits neatly on thePCB pads provided.Lightly tin the underside of the transistor tabs.Apply a small amount of heatsink compound (Dow-Corning 340 or equivalent) tothe transistor mounting surface.  Sufficient compound should be used to ensurean even film over the entire mounting surface.Place the transistor on the PCB in the correct orientation and ensure the tabs areflush to the surface.  Q410 Only: Lightly solder one tab to the PCB, then torque down the retain-ing nut to the correct torque (0.7Nm/6in.lbf.).Caution:Do not solder all the tabs before torquing down otherwise the devicemay be broken.Q420 Only: Refit the solder tags. Solder all transistor tabs to the PCB.Replace each component in exactly the same position as noted previously.

M850-00T858/859 General InformationD1.11Copyright TEL 24/01/001.1 IntroductionThe T858 and T859 are FM base station power amplifiers designed for single or mul-tichannel operation in the 400 to 520MHz frequency range.  The output power capabili-ties are as follows:T858 - 10 to 60WT859 - 20 to 110W.The older design T858/859 PAs (without RF power modules) comprise a broad band,three stage drive amplifier whose output is split to drive two separate output stages.The outputs from these final stages are then recombined and filtered before being fed tothe output socket.  This type of balanced output stage offers two advantages over singleended types:• improved intermodulation performance in the presence of high signal levelsfrom adjacent transmitters;• enhanced reliability:  if one of the two output stages fails, the transmitter canstill produce one quarter of its rated power.The later design T858 PA (with RF power module) comprises a broad band, two stagedrive amplifier whose output is filtered before being fed to the output connector.The later design T859 PA (with RF power module) comprises a broad band, two stagedrive amplifier whose output is split to drive two separate output stages.  The outputsfrom these final stages are then recombined and filtered before being fed to the outputsocket.  This type of balanced output stage offers two advantages over single endedtypes:• improved intermodulation performance in the presence of high signal levelsfrom adjacent transmitters;• enhanced reliability:  if one of the two output stages fails, the transmitter canstill produce one quarter of its rated power.VSWR and thermal protection are incorporated into the basic design, while monitoringand alarm signals are available for both forward and reverse power. The output poweris adjustable from the front panel.The main PCB is mounted directly on a die-cast chassis/heatsink.  Extensive use ismade of the latest surface mount technology.Forced air cooling for the heatsink is provided on the T859 by a fan, which is activatedwhenever the transmitter is keyed.  Thermal sensors will also activate the fan automati-cally if the internal temperature reaches an unacceptable level.The T858 has a width of 60mm and occupies a single space in a Tait rack frame, whichhas the ability to accommodate up to seven standard modules.  The T859 has a width of120mm and occupies a double space.

The output from the final is passed to theantenna socket via the harmonic filter.The driver stage of the T859 consists of a three-stage RF power module (#IC210) whichdelivers 30-40W to the final transistors.  The signal is split via a 3dB quadrature hybrid(L241) and used to drive the two final amplifiers (Q216, Q217).  The outputs from thesefinal stages are recombined by L240 and passed to the antenna socket via the harmonicfilter.The diplexer presents the final amplifiers with a good load at harmonic frequencies,which helps to achieve the expected harmonic attenuation in the output filter.The directional coupler senses forward and reflected power, which is rectified (D205 &D206) and passed to the control circuitry for metering, alarm and power control pur-poses.Power control is via a series pass transistor (Q137 [Q128]), which controls the supplyvoltage on the first two-stage of #IC210.

M850-00T858/859 Circuit OperationD2.7Copyright TEL 24/01/002.3.1 Power ControlThe DC voltages from the directional coupler representing forward and reflected powerare buffered by the two voltage followers, IC103 [IC100] pins 1, 2 & 3 and pins 12, 13 &14.  Their outputs are summed at an integrator (IC105 [IC110] pins 1, 2 & 3), whichdrives the series pass control elements (Q135 & Q137 [Q124 & Q128]).Forward and reflected power are summed so that, under high output VSWR, the powercontrol turns the PA down.  This is because the control loop adjusts for the same DCvoltage from the directional coupler that would have been present if there were noreflected power.2.3.2 Driver Power LevelThe maximum output power of the T858/859 can be limited by placing a ceiling on thedriver output power level using RV115 (accessible through the side cover).  For exam-ple, if RV115 is set for a maximum output power of 50W, the range of adjustment usingRV109 (front panel power adjust) will be 20 to 50W.Caution:The driver power level clamp (RV115) is factory set to give a maximumpower output at room temperature of 60W for the T858 and 110W forthe T859.  The unit may be damaged if this level is increased.2.3.3 Thermal ProtectionAt excessively high temperatures, the output power will automatically reduce to a pre-set level (set by RV113), thus preventing the PA from overheating.  Ambient temperature within the PA is measured by a thermistor controlled voltagedivider (R168 [R177], R210) which applies a voltage to a comparator with hysteresis(IC101 [IC105] pins 8, 9 & 10).  This thermistor is located on the PCB in the low pass fil-ter cavity.Thermal protection is also provided for the RF power module to prevent the moduleitself from overheating.  This protection consists of a thermistor controlled voltagedivider (R203, R215 [R200]) which sets a voltage on a comparator with hysteresis (IC200pins 1, 2 & 3).  The thermistor is located on the module flange.The output current from all comparators is summed into the power control network viaRV113 so that the power level to which the PA must turn down may be set.

Theinputs are from the forward and reverse power signals from the directional coupler,buffered by IC103 [IC100] pins 1, 2 & 3 and pins 12, 13 & 14.  Thus, the power levels atwhich the forward and reverse power alarms are triggered are defined by RV101 andRV105 respectively.2.3.5 Forward And Reverse Power MeteringForward and reverse power signals from the two IC103 [IC100] buffers are available formetering purposes.

If the output power level is low, check that the high tempera-ture shutdown circuit has not activated by verifying that IC101 [IC105] pin 8is low.Adjust RV115 to reduce the maximum power output to:T858 - 60WT859 - 110W.Adjust RV109 [%RV109] to set the power output to the required level (e.g. 50W forthe T858, 100W for the T859).3.5 High Temperature Shutdown Power LevelSet RV109 [%RV109] (front panel power control) to the required output power.Simulate high operating temperatures by placing a shorting link on PL110 pins 5-6(do not use either of the links from PL110 pins 11-12 or 13-14 to do this).Adjust RV113 (shutdown power level) for an output power of:T858 - 20WT859 - 40W.Remove the shorting link from PL110 pins 5-6 to return the PA to normal opera-tion.3.6 Remote Forward Power Meter CalibrationIf a remote meter is connected, adjust RV103 (forward power meter calibration)for the remote reading to agree with the RF power meter reading.3.7 Remote Reverse Power Meter CalibrationIf a remote meter is connected, connect a 50 ohm 3dB pad (with the output opencircuit) to the PA output.Apply RF drive and Tx-Key.Adjust RV107 (reverse power meter calibration) for a quarter of the forwardpower reading.

Ensure that these links are set as standard before starting and aftercompleting the adjustment procedure.4.3 Component ChecksIf you suspect a transistor is faulty, you can assess its performance by measuring the for-ward and reverse resistance of the junctions.  Unless the device is completely desol-dered, first make sure that the transistor is not shunted by some circuit resistance (e.g. abase choke).  Use a good quality EVM (e.g. Fluke 75) for taking the measurements (or a20k ohm/V or better multimeter, using only the medium or low resistance ranges).Caution:Before operating the PA, replace any RF base chokes removed whilemaking measurements.The collector current drawn by multi-junction transistors is a further guide to their per-formance.Link Pins Standard Setting Function1-2, 3-4,7-8, 9-10not linked Not used.5-6 not linked Pins 5-6 are provided for simulating high operating temperatures during initial adjustment.  Bridging this link shorts out R215 [R200] and R210 (NTCs), thus turning on the thermal protection circuitry.  They should not be linked for normal operation.11-1213-14linked Pins 11-12 and 13-14 are provided for fac-tory testing only.  The PA will not function correctly if these settings are changed.
D4.4T858/859 Fault FindingM850-0024/01/00 Copyright TELIf an IC is suspect, the most reliable check is to measure the DC operating voltages.  Dueto the catastrophic nature of most IC failures, the pin voltages will usually be markedlydifferent from the recommended values in the presence of a fault.  The recommendedvalues can be obtained from either the circuit diagram or the component data catalogue.4.4 DC ChecksNote:No RF power is to be applied during these checks.Check that +13.8V is present on the collectors of Q216 (T858) or Q216 and Q217(T859).  Make this measurement when the transmitter is not keyed.Check that approximately 8-13.8V is present on pin 2 of #IC210 (the level isdependent on RV115 being set to maximum).Check that +13.8V is present at pin 4 of IC100.Check that approximately +12V is present at pin 8 of IC110 (the level is dependenton RV115 being set to maximum).Check that +7.0V is present at the output of regulator IC130.4.5 RF Checks4.5.1 T858The T858 PA Fault Finding Chart (Section 4.6.1) provides a systematic approach forlocating a fault in the RF circuitry.
