M850-003Copyright TEL 31/09/98About This ManualScope This manual contains general, technical and servicing informa-tion on T850 Series II 25W, 50W and 100W base stations whichcomprise the following equipment:Format We have published this manual in a ring binder so that "revisionpackages" containing additional information pertaining to newissues of PCBs can be added as required.Revision Packages Revision packages will normally be published to coincide withthe release of information on a new PCB, and may also containadditions or corrections pertaining to other parts of the manual.You may order as many packages as you require from your localTait Dealer or Customer Service Organisation.  Revision pack-ages are supplied ready-punched for inclusion in your manual.Revision Control Each page in this manual has a date of issue.  This is to complywith various Quality Standards, but will also serve to identifywhich pages have been updated and when.  Each page and itspublication date is listed in the "List of Effective Pages", and anew list containing any new/revised pages and their publica-tion dates will be sent with each revision package.Any portion of text that has been changed is marked by a verti-cal line (as shown at left) in the outer margin of the page.  Wherethe removal of an entire paragraph means there is no text left tomark, an arrow (as shown at left) will appear in the outer mar-gin.  The number beside the arrow will indicate how many para-graphs have been deleted.The manual issue and revision status are indicated by the lastthree digits of the manual product code. These digits start at 200and will increment through 201, 202, 203, etc., as revision pack-ages are published, e.g:  Thus, issue 203 indicates the third revision to issue 2 and meansthat three packages should have been added to the manual.

M850-00MechanicalA2.1Copyright TEL 31/09/982 Mechanical2.1 Torx Recess Head ScrewsTorx recess head screws are becoming the standard screw head type in all T800 Series IIequipment, with Pozidriv and Philips recess head screws being used in fewer applica-tions.  The Torx recess head has the advantage of improved screwdriver tip location, reducingthe chances of screw head damage caused by the driver tip rotating within the recess.  Inaddition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw withthe driver on a slight angle, which can be useful in situations where access is restricted.It is important that you use the correct Torx screwdriver tip:M3 screws - T10M4 screws - T20.Figure 2.1 below shows a typical Torx recess head screw (actual hardware may differslightly from this illustration due to variations in manufacturing techniques).Figure 2.1   Torx Screw Identification"star" shaped recess withsix internal notches
A2.2MechanicalM850-0031/09/98 Copyright TEL2.2 Pozidriv & Philips Recess Head ScrewsPozidriv and Philips recess head screws will continue to be used in T800 Series II equip-ment in a few special applications.  It is important that you use the correct type and sizescrewdriver for each screw type to avoid damaging the screw head.  It is particularly important that you do not use Philips screwdrivers on Pozidriv screwheads as the tapered driving flutes of the Philips screwdriver do not engage correctlywith the parallel-sided slots in the Pozidriv screw head.  This can result in considerabledamage to the screw head if the screwdriver tip turns inside the recess.Note:If you find you need excessive downwards pressure to keep the screwdrivertip in the Pozidriv screw head, you are probably using the wrong type and/or size screwdriver.Figure 2.2 below shows the main differences between typical Pozidriv and Philips screwheads and screwdriver tips (actual hardware may differ slightly from these illustrationsdue to variations in manufacturing techniques).

M850-00Component ReplacementA3.1Copyright TEL 31/09/983 Component Replacement3.1 Leaded ComponentsWhenever you are doing any work on the PCB that involves removing or fitting compo-nents, you must take care not to damage the copper tracks.  The two satisfactory meth-ods of removing components from plated-through hole (PTH) PCBs are detailed below.Note:The first method requires the use of a desoldering station, e.g. Philips SBC314 or Pace MBT-100E.3.1.1 Desoldering Iron MethodPlace the tip over the lead and, as the solder starts to melt, move the tip in a circu-lar motion.Start the suction and continue the movement until 3 or 4 circles have been com-pleted.Remove the tip while continuing suction to ensure that all solder is removed fromthe joint, then stop the suction.Before pulling the lead out, ensure it is not stuck to the plating.If the lead is still not free, resolder the joint and try again.Note:The desoldering iron does not usually have enough heat to desolder leadsfrom the ground plane.  Additional heat may be applied by holding a sol-dering iron on the tip of the desoldering iron (this may require some addi-tional help).3.1.2 Component Cutting MethodCut the leads on the component side of the PCB.Heat the solder joint sufficiently to allow easy removal of the lead by drawing itout from the component side:  do not use undue force.Fill the hole with solder and then clear with solderwick.
A3.2Component ReplacementM850-0031/09/98 Copyright TEL3.2 Surface Mount DevicesCaution:Surface mount devices (SMDs) require special storage, handling,removal and replacement techniques.  This equipment should be serv-iced only by an approved Tait Dealer or Customer Service Organisa-tion equipped with the necessary facilities.  Repairs attempted withincorrect equipment or by untrained personnel may result in perma-nent damage.  If in doubt, contact your nearest Tait Dealer or CustomerService Organisation.3.3 Cased Mica CapacitorsCased mica capacitors can be removed by heating the top with a heavy-duty solderingiron and gently lifting the capacitor off the PCB with a solder-resistant spike or equiva-lent.

M850-00T855 General InformationB1.5Copyright TEL 31/09/981.1 IntroductionThe T855 is a high performance microprocessor controlled FM base station receiverdesigned for single or multichannel operation in the 400 to 530MHz frequency range1.The receiver is a dual conversion superhet with a synthesised local oscillator.  The firstIF is 45.0MHz, allowing exceptionally high spurious signal rejection to be achieved inthe receiver front end.   The second IF section (455kHz) combines amplitude limiting,detection and audio preamplification within a single integrated circuit.  It also drivescarrier and noise level detectors for signal strength indication and gating the audio out-put.  RSSI can be used to drive a carrier mute for audio output gating (link selectable)when the optional T800-04-0000 RSSI PCB is fitted.The audio section output can be adjusted to deliver >+10dBm to a 600 ohm balancedoutput, and 1W to a local monitor speaker.  A flat or de-emphasised audio response islink selectable.The synthesiser frequency is programmed via the serial communications port. Eightchannel select lines are accessible via an additional D-range connector (D-range 2 -T800-03-0000) at the rear of the set.All components except those on the VCO board are mounted on a single PCB.  This issecured to a die-cast chassis which is divided into compartments to individually shieldeach section of circuitry.  Access to both sides of the main PCB is obtained by removingeach of the two chassis covers.  There is provision within the chassis to mount smalloption PCBs.The front panel controls include gating sensitivity, line level, monitor volume and amonitor mute switch.  The T855 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.1. Although capable of operating over the 400-530MHz frequency range, the T855 has a 5MHz switching range (see Section 1.2.3 and Section 3.1).

This low loss filter (typically lessthan 0.5dB over 400-530MHz) provides excellent immunity to interference from highfrequency signals.The signal is then further filtered, using a high performance helical resonator doublet(FL410) which provides exceptional image rejection, before being amplified by approxi-mately 8dB (Q410).  The signal is then passed through a further helical filter doublet(FL420) before being presented to the mixer via a 2dB attenuator pad.Each sub-block within the front end has been designed with 50 ohm terminations forease of testing and fault finding.

M850-00T855 Circuit OperationB2.5Copyright TEL 31/09/982.3 Mixer(Refer to the front end circuit diagram (sheet 4) in Section 6.3 and Figure 2.2.)IC410 is a high level mixer requiring a local oscillator (LO) drive level of +17dBm (nom-inal).  The voltage controlled oscillator (VCO) generates a level of +21dBm (typical) andthis is fed to the mixer via a 5dB attenuator pad.  A diplexer terminates the IF port of themixer in a good 50 ohms, thus preventing unnecessary intermodulation distortion.2.4 IF Circuitry(Refer to the IF section circuit diagram (sheet 3) in Section 6.3 and Figure 2.2.)Losses in the mixer are made up for in a tuned, common gate, post mixer amplifier(Q310).  Several stages of amplification and filtering are employed in the IF circuitry.The first crystal filter is a 4-pole device (&XF300) which is matched into 50 ohms on bothits input and output ports.  This stage is followed by a common base amplifier (Q320)whose output is matched into a 2-pole crystal filter (&XF301). The signal is then ampli-fied using a high gain MOSFET amplifier (Q330), after which the signal is mixed downto 455kHz with the second crystal local oscillator (44.5455MHz).The 455kHz signal is filtered using a 6-pole ceramic filter (&XF302) before being limitedand detected. Q340 provides a buffered 455kHz output for use with the optional RFlevel detector (RSSI)The second IF mixer, limiter and detector is in a 16-pin IC (IC310).  Quadrature detectionis employed, using L390, and the recovered audio on pin 9 of IC310 is typically 1V p-pfor 60% system deviation.
B2.6T855 Circuit OperationM850-0031/09/98 Copyright TEL2.5 Noise Mute (Squelch)(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respec-tively) in Section 6.3 and Figure 2.2.)The noise mute operates on the detected noise outside the audio bandwidth.  An opera-tional amplifier in IC310 is used as an active band pass filter centred on 70kHz to filterout audio components.  The noise spectrum is then further amplified in a variable gain,two-stage amplifier (Q350 & Q360) with additional filtering.  The noise is then rectified(D310) and filtered to produce a DC voltage proportional to the noise amplitude.  Thelowest average DC voltage corresponds to a high RF signal strength and the highest DCvoltage corresponds to no signal at the RF input.The rectified noise voltage is compared with a threshold voltage set up on RV230, thefront panel "Gating Sensitivity" potentiometer.  Hysteresis is provided by the feedbackresistor (R267) to prevent the received message from being chopped when the averagenoise voltage is close to the threshold.  R281 and R280 determine the mute opening andclosing times and, in combination with solder links SL210 and SL220, provide three timedelay options (SL210 is linked as standard - refer to Section 3.8). The mute control signalat pin 7 of IC270 is used to disable the speaker and line audio outputs.  The speaker out-put can be separately enabled for test purposes by operating the front panel mute disa-ble switch, SW201.2.6 Carrier Mute(Refer to the audio processor and IF section circuit diagrams (sheets 2 and 3 respec-tively) in Section 6.3 and Figure 2.2.)A high level carrier mute facility is also available.  The RSSI (refer to Section 2.12) pro-vides a DC voltage proportional to the signal strength.  This voltage is compared with apreset level, set up on RV235, and may be linked into the mute timing circuit usingPL250.  PL250 selects either the noise mute or the carrier mute.  From this point both thenoise and carrier mute circuits operate in the same manner, using common circuitry.

Linking(PL220 & PL210) is available to give either a flat or de-emphasised audio response, withde-emphasis giving a -6dB/octave roll off.  The output of IC210 is split to provide sepa-rate paths for the speaker and line outputs.  The "Audio 1", Audio 2" and "Speech" linesallow access to the receiver’s audio path for external signalling purposes (refer to Sec-tion 3.5).The signals are passed to audio drive amplifiers IC240 and IC260.  Under muted condi-tions the inputs of these amplifiers are shunted to ground via transistors Q230 and Q290respectively.  The audio output of IC240 has a DC component which is removed byC249, and this then drives a speaker directly.  The output of IC260 is fed into a line trans-former to provide a balanced 2-wire or 4-wire, 600 ohm output.The speaker volume is set using the front panel "Monitor Volume" knob (RV205) and theline level is set using the recessed "Line Level" potentiometer (RV210).  The red front panel "Gate" LED (D250) indicates the status of the mute circuit.  When asignal above the mute threshold is received, the LED is illuminated.  The "MonitorMute" switch (SW201) on the front panel opens the mute, allowing continuous monitor-ing of the audio signal (on = audio muted;  off = audio unmuted).The mute control line is available on pad 234 ("RX GATE OUT") for control of externalcircuitry.  A high (9V) on pad 234 indicates that the audio is disabled and a low (0V)indicates that a signal above the mute threshold level is being received.FromIF StageDemodulatedSignal(*IF AudioCompensationCircuit)Driver AmpLine Output12VRelaySpeechAudio 1Output Audio 2InputHigh PassFilterSpeakerMuteLineMuteCarrierMuteRSSI(Optional)Rx DisableTimerNoiseMutePL260PL250PL270RSSI OutputMute RelayGate OutputRx Disable(Optional Pad)Mute DisableSpeaker OutputLine Monitor121221315223341PL240PL230Driver AmpFlat/De-emphasisLPFPL21023Flat/De-emphasisAmplifierPL220123*IFCompMonitorVolumeLineLevel

An adjustable timedelay (RV220) is provided on these lines.  In order to disable the audio, either pad mustbe pulled to 0V (refer to Section 1.4 in Part G).  An undedicated relay is provided (RL210) for transmitter keying or other functions andthis can be operated from the mute line by linking PL270.2.8 Power Supply And Regulators(Refer to the regulators circuit diagram (sheet 6) in Section 6.3.)Figure 2.4   T855 Power Supply And Regulators Block DiagramThe T855 is designed to operate off a 10.8-16V DC supply (13.8V nominal).  A 5.3V regu-lator (IC630) runs directly from the 13.8V rail, driving much of the synthesiser circuitry.It is also used as the reference for a DC amplifier (IC640, Q630 & Q620) which providesa medium current capability 9V supply.A switching power supply, based on Q670 and Q660, runs off the 9V supply and pro-vides a low current capability +20V supply.  This is used to drive the synthesiser loopfilter (IC740), giving a VCO control voltage of up to 20V.The 13.8V supply drives both output audio amplifiers without additional regulation.

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 reference oscillator (fref).A reference oscillator at 12.8MHz (IC700) is buffered (IC710) and divided down to6.25kHz or 5kHz within the synthesiser IC (IC740).A buffered output of the VCO is divided with a prescaler and programmable dividerwhich is incorporated into the synthesiser chip (IC740).  This signal is compared withthe reference signal at the phase detector (also part of the synthesiser chip).  The phasedetector outputs drive a balanced charge pump circuit (Q760, Q770, Q775, Q780, Q785)and active loop filter (IC750, Q790) which produces a DC voltage between 0V and 20Vto tune the VCO.  This VCO control line is further filtered to attenuate noise and otherspurious signals.

The transmission line is used in a two port configuration with varicapspositioned at one end. The VCO control voltage from the loop filter (IC750) is applied tothe varicaps (D1 & D2) to facilitate tuning. The VCO output is coupled into a cascodeamplifier stage (Q2 & Q3) which supplies +10dBm (nominal) output. Further amplifica-tion in Q5 brings the output drive level to +20dBm to drive the mixer. A low level "sniff" is taken from the input to Q5 to drive the divider buffer to the synthe-siser (IC740). The VCO operates at the actual frequency required by the first mixer, i.e. there are nomultiplier stages. The VCO frequency spans from either 355-395MHz, 395-435MHz or 435-485MHzaccording to product type (refer to Section 1.4).  The VCO is tuned to 45MHz below thedesired receive frequency (low side injection) to produce a 45MHz IF signal at the out-put of the mixer.
B2.12T855 Circuit OperationM850-0031/09/98 Copyright TEL2.12 Received Signal Strength Indicator (RSSI)(Refer to the T800-04-0000 RSSI PCB circuit diagram in Section 6.2 and the IF section cir-cuit diagram (sheet 3) in Section 6.3.)The RSSI option PCB plugs directly into the main PCB (support circuitry being fitted asstandard).  It is fitted to the T855 whenever receiver signal strength monitoring isrequired, e.g. trunking or voting.  Its function is to provide a DC voltage proportional tothe signal level at the receiver input.  The DC voltage is available at D-range 1 (PL100pin 5).The RSSI also provides the capability for high level signal strength muting, which maybe selected on PL250 (refer to Section 3.5).  The mute threshold may be set between-115dBm and -70dBm by RV235.Figure 2.7   T855 RSSI Block Diagram (T800-04-0000 RSSI PCB)The variable gain stage (Q1A) is a common emitter amplifier with its emitter groundedand the AGC control loop voltage applied to its base.  Since the AGC loop will maintaina constant signal level at the collector, the gain of Q1 must be proportional to the incom-ing 455kHz signal level.  The gain of Q1 is linearly proportional to its collector currentwhich itself is exponentially related to the base-emitter voltage.  Thus there is a logarith-mic relationship between the base-emitter voltage and the gain.  The circuit thereforeproduces a feedback voltage, and an output voltage, logarithmically related to the RFinput signal.The AGC loop is followed by a DC amplifier which provides level shifting, temperaturecompensation and gain to give a nominal 1V/10dB at the RSSI output.  RV320 on themain PCB is used to set the RSSI voltage to a fixed value at a given RF input signalstrength.+VAmp Detector Error AmpQ1C Q1A &Q1B                 VDCVariableGain StageQ1ERSSIInputTemp CompNTCDC Amp(Gain= x33)TempCompQ1DDC Offset(Ref)RSSI Output1V/10dB

M850-00T855 Initial Tuning & AdjustmentB3.3Copyright TEL 31/09/983.1 IntroductionWhen you receive your T855 receiver it will be run up and working on a particular fre-quency (the "default channel")1.  If you want to switch to a frequency that is within the5MHz switching range (i.e. ±2.5MHz from the factory programmed frequency), youshould only need to reprogram the receiver with the PGM800Win software (refer to thePGM800Win programming kit and Section 3.2 below).  However, if you want to switch to a frequency outside the 5MHz switching range, youwill have to reprogram and re-tune the receiver to ensure correct operation.  In this caseyou 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 receiver’s EEPROM memory(IC820) by using the PGM800Win software package and an IBM PC.  You can also usePGM800Win to select the receiver’s current operating frequency (or "default channel").If the receiver is installed in a rack frame, you can program it via the programming portin the speaker panel.  However, you can also program the receiver before it is installedin a rack frame as follows:• by using a T800-01-0010 calibration test unit;• via D-range 1;• via D-range 2 (standard T800-03-0000 auxiliary D-range only);• via SK805 (internal Micromatch connector).If you do not use the T800-01-0010, you will have to connect the PC to the receiver via amodule 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.

M850-00T855 Fault FindingB5.3Copyright TEL 31/09/985.1 Visual ChecksRemove the covers from the T855 and inspect the PCB for damaged or broken compo-nents, paying particular attention to the surface mounted devices (SMDs).Check for defective solder joints.  If repair or replacement of components is considerednecessary, refer to 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 receiver 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. receiver linked has the highest priority, followed by VCO error, theninternal error).Flash Rate Conditionfast (  sec. on/  sec. off approx.) receiver is linked with PGM800Winslow (1 sec. on/1 sec. off approx.)

Check that PL250 is linked correctly:noise mute 1-2carrier mute 2-3.Check that the mute gate opens as follows:noise mute -  rotate RV230 (front panel gating sensitivity) fully clock-wise and check that the front panel "Gate" LED turns on;carrier mute - rotate RV235 (carrier mute) fully clockwise and check thatthe front panel "Gate" LED turns on.If the mute fails to operate correctly, refer to the noise mute fault finding chart (Section5.7.4) or the carrier mute fault finding chart (Section 5.7.5).

Prepare a test cable by connecting a 1nF capacitor to theend of a length of coax cable as shown in Figure 5.1.Figure 5.1   RF Test CableNote:Before using the test cable, ensure the coax braid is connected to an earthpoint on the PCB.Using the RF test cable, apply a modulated 45MHz signal to the test breaks in theIF section, or an on-channel RF signal to the front end test breaks.Check that the sensitivity at each test break is within 2dB of the levels shown onthe circuit diagram.Poor sensitivity indicates a fault in one of the circuit blocks following the test break.Note:Poor sensitivity into the mixer can be caused by lack of drive level from theVCO (the drive level should be >+17dBm).Refer to the receiver fault finding charts (Section 5.7.6) for further information.1nFCoaxTo Test CableConnect To Earth

Alternatively, if you have an RSSI PCB fitted, use an oscilloscope probe forthe "Y" input to monitor the RSSI output voltage at pad P238 (RSSI test point) orpin 5 of D-range 1 (PL100).  This will give a demodulated log response and onlythe top half of the wave forms shown in Figure 5.2 and Figure 5.3 will be dis-played on the oscilloscope screen.Note:The "X" input should be DC coupled.

You can further verify the product type by checking the placement of anSMD resistor in the table that is screen printed onto the top side of the PCB, similar to the exampledrawn below.  In this example, the resistor indicates that the product was built as a T855-10-XXXX.  Note:The only function of this resistor is to indicate the product type.  It has no effect on thecircuitry or operation of the receiver.PCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02,  whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,02, 03, etc. as the PCB is updated.  Some issue PCBs never reach full production status and are there-fore not included in this manual.  A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.855-30 PRODUCT TYPE855-35 855-10 855-20855- 855-13 855-23PRODUCT TYPE 855-15 855-25
B6.1.4T855 PCB InformationM850-0031/09/98 Copyright TELParts ListsThe 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs).  We canprocess your spare parts orders more efficiently and accurately if you quote the IPN and provide abrief description of the part.The components listed in this parts list are divided into two main types:  those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order withineach group.  Each component entry comprises three or four columns, as shown below:The miscellaneous and mechanical section lists the variant and common parts in IPN order.Parts List AmendmentsAt the front of the parts list is the Parts List Amendments box (an example of which is shownbelow).  This box contains a list of component changes which took place after the parts list and dia-grams in this section were compiled.  These changes (e.g. value changes, added/deleted compo-nents, etc.) are listed by circuit reference in alphanumeric order and supersede the informationgiven in the parts list or diagrams.  Components without circuit references are listed in IPN order.The number in brackets at the end of each entry refers to the Tait internal Change Order document.circuit reference -lists componentsin alphanumericordervariant column -indicates that this isa variant componentwhich is fitted only tothe product type listedInternal Part Number -order the componentby this numberdescription -gives a brief descriptionof the componentParts List AmendmentsR306 Changed from 180Ωto 560Ω(036-13560-00) to increase sensitivity (71003).circuit referenceor IPN descriptionof changeIPN of newcomponent Change Ordernumber
M850-00T855 PCB InformationB6.1.5Copyright TEL 31/09/98Variant ComponentsA variant component is one that has the same circuit reference but different value or specification indifferent product types.  Where two products share the same PCB, the term “variant” is also used todescribe components unplaced in one product.  Variant components have a character prefix, such as“&”, “=” or “#”, before the circuit reference (e.g. &R100).The table below explains the variant prefixes used in T800 Series II products:Grid Reference IndexThis section contains a component grid reference index to help you find components and labelledpads on the PCB layouts and circuit diagrams.  This index lists the components and pads in alpha-numeric order, along with the appropriate alphanumeric grid references, as shown below:If the variant prefix is. . . the component will. . .& change according to channel spacing= change according to frequency stability# change according to frequency range% be placed or unplaced for special applications*be unplaced in one product(where two products share the same PCB)circuit diagramreferencePCB layoutreferencecomponents listedin alphanumeric orderlayer number -1 = top side layer2 = bottom side layercomponent locationon the layersheet numbercomponent locationon the sheet
B6.1.6T855 PCB InformationM850-0031/09/98 Copyright TELUsing CAD Circuit DiagramsReading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumericborder.  The circuit diagrams in this manual use letters to represent the horizontal axis, and num-bers for the vertical axis.  These circuit diagram “grid references” are useful in following a circuitthat is spread over two or more sheets.When a line representing part of the circuitry is discontinued, a reference will be given at the end ofthe line to indicate where the rest of the circuitry is located, as shown below.  The first digit refers tothe sheet number and the last two characters refer to the location on that sheet of the continuation ofthe circuit (e.g. 1R3).C3014N7R30312DSGL31033UIF-SIG4R4C369100PC37110UR339100K%R338100DISCRIMINATOR1R32R92R98A2these grid referencesshow where the circuitis continued

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.

M850-00T856/857 Circuit OperationC2.9Copyright TEL 31/09/982.5.3 Keying InputsThere are four ways to key the exciter: • pulling the Tx-Key line low (pin 13 on D-range 1 [PL100]) at the rear of the set);• pushing the "Carrier" button on the front panel - this will inhibit all audio;• using the PTT button on the local microphone, disabling audio from the line;• via the opto-key inputs (pins 11 and 12 on D-range 1 [PL100]) when electricalisolation is required.  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 T856 has a regulator(IC370) which produces 9V for use in the exciter and audio circuits.A switching power supply (Q660, Q670) runs from the 9V supply and provides a lowcurrent capability +20V supply.  This is used to drive the synthesiser loop filter (IC750),giving a VCO control voltage range of up to 20V.Ultimate control of the transmitter is via the Tx-Reg. supply, switched from 9V by Q610.This is enabled via the Tx-Enable signal from the audio processor, and microprocessor.

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.

IC300 pin 1,Q302, and Q303 provide a 9V regulated supply for the exciter.To reduce the spurious output level when the synthesiser is out-of-lock, the Tx-Reg. andLock-Detect signals are gated to inhibit the exciter control circuit and to switch off theRF signal at the input to the drive amplifier.  This is achieved by a PIN switch attenuator(D201, D202, D203).Cyclic keying control is provided by additional circuitry consisting of several timedelay, ramp and gate stages:• Q301, Q302, Q303, IC300 power ramping• Q310, Q311 Tx-Reg. and Lock-Detect gate• Q306, Q307, Q308, Q309 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.R517, R518 and R519 form a 3dB attenuator to provide good VCO/drive amplifier isola-tion as well as the correct exciter drive levelNote:The exciter provides a DC control signal to the PA via the RF coax.

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. Inject an audio signal of 300Hz 1.5V rms (+5dBm) into the CTCSS input (D-range1 (PL100) pin 8). Key the transmitter by earthing the Tx-Key line.2. Adjust the output from the audio generator to obtain ±3kHz (±2.4kHz) [±1.5kHz]deviation at 300Hz.3. Change the input frequency to 100Hz and adjust IC220 via PGM800Win “refer-ence modulation” to obtain ±3kHz (±2.4kHz) [±1.5kHz] deviation (you can useeither the mouse or up and down arrow keys).4. Change the input frequency back to 300Hz.Repeat steps 2 and 3 above until the deviations achieved at the two input frequen-cies are within 0.2dB of each other.  You will need to do this at least four times.5. Sweep the audio between 50 and 300Hz for peaks.Note:A peak between 50 and 300Hz will indicate a fault condition, i.e:-  incorrect set-up or -  modulation circuitry fault.

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.)

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

M850-00T856/857 PCB InformationC6.1.3Copyright TEL 31/09/986.1 IntroductionProduct Type IdentificationYou can identify the transmitter or exciter type by checking the product code printed on a label onthe rear of the chassis (product codes are explained in Section 1.3 in this Part of the manual, and Fig-ure 1.1 in Part A shows typical labels).  You can further verify the product type by checking theplacement of an SMD resistor in the table that is screen printed onto the top side of the PCB, similarto the example drawn below.  In this example, the resistor indicates that the product was built as aT856-10-XXXX.  Note:The only function of this resistor is to indicate the product type.  It has no effect on thecircuitry or operation of the transmitter or exciter.PCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02,  whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,02, 03, etc. as the PCB is updated.  Some issue PCBs never reach full production status and are there-fore not included in this manual.  A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.856-30 PRODUCT TYPE856-35 856-10 856-20856- 856-13 856-23PRODUCT TYPE 856-15 856-25

We canprocess your spare parts orders more efficiently and accurately if you quote the IPN and provide abrief description of the part.The components listed in this parts list are divided into two main types:  those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order withineach group.  Each component entry comprises three or four columns, as shown below:The miscellaneous and mechanical section lists the variant and common parts in IPN order.Parts List AmendmentsAt the front of the parts list is the Parts List Amendments box (an example of which is shownbelow).  This box contains a list of component changes which took place after the parts list and dia-grams in this section were compiled.  These changes (e.g. value changes, added/deleted compo-nents, etc.) are listed by circuit reference in alphanumeric order and supersede the informationgiven in the parts list or diagrams.

Where two products share the same PCB, the term “variant” is also used todescribe components unplaced in one product.  Variant components have a character prefix, such as“&”, “=” or “#”, before the circuit reference (e.g. &R100).The table below explains the variant prefixes used in T800 Series II products:Grid Reference IndexThis section contains a component grid reference index to help you find components and labelledpads on the PCB layouts and circuit diagrams.

The circuit diagrams in this manual use letters to represent the horizontal axis, and num-bers for the vertical axis.  These circuit diagram “grid references” are useful in following a circuitthat is spread over two or more sheets.When a line representing part of the circuitry is discontinued, a reference will be given at the end ofthe line to indicate where the rest of the circuitry is located, as shown below.

M850-00T858/859 General InformationD1.7Copyright TEL 31/09/981.1 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 PA comprises a broad band, three stage drive amplifier whose output is split todrive two separate output stages.  The outputs from these final stages are then recom-bined and filtered before being fed to the output socket.  This type of balanced outputstage offers two advantages over single ended 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.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.

This signal is split via a 3dBcoupler (L19) and used to drive the two final amplifiers (Q6 & Q7).  The outputs fromthe finals are passed to the antenna socket via the harmonic filter.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 (D1 & D2)and passed to the control circuitry for metering, alarm and power control purposes.Power control is via a series pass transistor (Q16), which controls the supply voltage onthe collector of the driver transistor (Q1).

D2.6T858/859 Circuit OperationM850-0031/09/98 Copyright TEL2.3.1 Power ControlThe DC voltages from the directional coupler representing forward and reflected powerare buffered by the two voltage followers IC3 pins 1, 2 & 3 and pins 5, 6 & 7.  Their out-puts are summed at an integrator (IC1 pins 8, 9 & 10), which drives the series pass con-trol element (Q16).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 T859 Driver Power LevelA ceiling is placed on the output power available from driver stages Q1, Q3 and Q4 toensure final stages Q6 and Q7 are not overdriven.  This is achieved by RV69 and IC4controlling the reference voltage of power control error amplifier IC1c, which in turnlimits the maximum supply voltage that can be applied to driver Q4 by power controltransistor Q16.Note:T859 PAs with serial numbers prior to 217262 do not have this feature.Caution:The driver power level clamp (RV69) is factory set to give a maximumpower output of 110W in the T859.  The unit may be damaged if thislevel is increased.2.3.3 Thermal ProtectionAt excessively high temperatures, the output power will automatically reduce to a pre-set level, thus preventing the PA from overheating.A thermistor controlled voltage divider (R68, R72) applies a voltage to a comparatorwith hysteresis (IC1 pins 12, 13 & 14).  Note:In all T858 PAs and T859 PAs with serial numbers prior to 217262, thethreshold of the comparator is independently set by RV69 which sets theshutdown temperature.  On later model T859 PAs this threshold is fixed.The output current from the comparator is summed into the power control network viaRV74 so that the power level to which the PA must turn down may be set.

The inputs are from the for-ward and reverse power signals generated by the directional coupler, buffered by IC3pins 1, 2 & 3 and pins 5, 6 & 7.  Thus, the power levels at which the forward and reversepower alarms are triggered are defined by RV48 and RV52 respectively.2.3.5 Forward And Reverse Power MeteringForward and reverse power signals from the two IC3 buffers are available for meteringpurposes.  The output currents are adjustable via RV43 (forward power) and RV57(reverse power).2.3.6 T859 Fan Control CircuitryFigure 2.4   T859 Fan Control Logic DiagramComparator IC3 pins 8, 9 & 10 are set to trigger at heatsink temperatures greater than+70°C, and pins 12, 13 & 14 at temperatures greater than -10°C.A logic AND function is applied to the comparator outputs by Q20 and Q21, therebyturning on the fan unconditionally (via Q17 and Q18) if the heatsink temperatureexceeds +70°C.A logic OR function is applied to the comparator IC3 pins 8, 9 & 10 and Tx-Key signals,thereby turning on the fan when the transmitter is keyed and the temperature isbetween -10°C and +70°C.Q17 Q18 FanRef +High Temp.SenseComparatorIC3CR72Ref +Low Temp.SenseComparatorIC3DR116NTCNTCTx KeyInvertQ19 ORQ20,R106, R107NANDQ20, Q21,R119, R120 Fan Driver13.8VFiltered

Also check for defective solder joints.Refer to Section 4.7, Section 4.8 and Section 3 of Part A for more details on repairand replacement of components.4.2 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.4.3 DC ChecksNote:No RF power is to be applied during these checks.Check that +13.8V is present on the collectors of Q3, Q4, Q5, Q6 and Q7.

You must measure all other stageswith a power meter at the 50Ω points in the circuit.For problems with the power control circuitry, refer to the Power Control Fault FindingCharts (Section 4.6.2 or Section 4.6.4 as appropriate).4.4.2 PA FaultsIf a PA fault has occurred, or is suspected, it is easier to find if the various stages are iso-lated by use of the test breaks (refer to Figure 4.1) and each stage analysed individually.These 50Ω test break points have been included throughout the RF circuitry to enableindividual transistor stages to be tested.Note 1:Use good quality 50Ω coax for the "flying" test leads.Note 2:Ensure each output is terminated in a 50Ω load of the correct power rating.

PCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-01390-02,  whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,02, 03, etc. as the PCB is updated.  Some issue PCBs never reach full production status and are there-fore not included in this manual.  A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.

We canprocess your spare parts orders more efficiently and accurately if you quote the IPN and provide abrief description of the part.The components listed in this parts list are divided into two main types:  those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order withineach group.  Each component entry comprises three or four columns, as shown below:The miscellaneous and mechanical section lists the variant and common parts in IPN order.Parts List AmendmentsAt the front of the parts list is the Parts List Amendments box (an example of which is shownbelow).  This box contains a list of component changes which took place after the parts list and dia-grams in this section were compiled.  These changes (e.g. value changes, added/deleted compo-nents, etc.) are listed by circuit reference in alphanumeric order and supersede the informationgiven in the parts list or diagrams.

The circuit diagrams in this manual use letters to represent the horizontal axis, and num-bers for the vertical axis.  These circuit diagram “grid references” are useful in following a circuitthat is spread over two or more sheets.When a line representing part of the circuitry is discontinued, a reference will be given at the end ofthe line to indicate where the rest of the circuitry is located, as shown below.

M850-00IntroductionE1.1Copyright TEL 31/09/981 IntroductionPCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00,  whichis screen printed onto the PCB (usually on the top side), as shown in the example below:The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,02, 03, etc. as the PCB is updated.  Some issue PCBs never reach full production status and are there-fore not included in this manual.  A letter following the 10 digit IPN has no relevance in identifyingthe PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.Parts ListsThe 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs).  We canprocess your spare parts orders more efficiently and accurately if you quote the IPN and provide abrief description of the part.The components listed in this parts list are divided into two main types:  those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order withineach group.  Each component entry comprises three or four columns, as shown below:The mechanical and miscellaneous section lists the variant and common parts in IPN order.circuit reference -lists componentsin alphanumericordervariant column -indicates that this isa variant componentwhich is fitted only tothe product type listedInternal Part Number -order the componentby this numberdescription -gives a brief descriptionof the component
E1.2IntroductionM850-0031/09/98 Copyright TELParts List AmendmentsAt the front of the parts list is the Parts List Amendments box (an example of which is shownbelow).  This box contains a list of component changes which took place after the parts list and dia-grams in this section were compiled.  These changes (e.g. value changes, added/deleted compo-nents, etc.) are listed by circuit reference in alphanumeric order and supersede the informationgiven in the parts list or diagrams.  Components without circuit references are listed in IPN order.The number in brackets at the end of each entry refers to the Tait internal Change Order document.Variant ComponentsA variant component is one that has the same circuit reference but different value or specification indifferent product types.  Variant components have a character prefix, such as “&”, “=” or “#”, beforethe circuit reference (e.g. &R100).Parts List AmendmentsR306 Changed from 180Ωto 560Ω(036-13560-00) to increase sensitivity (71003).circuit referenceor IPN descriptionof changeIPN of newcomponent Change Ordernumber

A link (PL270) is available for control of therelay from the mute circuit (refer to Section 1.7).  This makes the relay suitable for con-trolling the keying of a transmitter in repeater applications.1.3 Mute SelectionLink PL250 may be set to operate with noise mute or carrier mute (refer to Section 1.7).1.4 Receiver DisableThe receiver audio can be disabled by pulling the RX-DISABLE line low.  When the cir-cuit is pulled from low to high, the receiver audio cannot be re-enabled until the disabletimer completes its operation.  This time is variable from 15ms to 200ms by adjustingRV220 in the audio processor section.If required, the operation of this circuit can be disabled by changing the link of PL260from 1-2 to 2-3.Typical applications of the receiver disable are as an extra mute for signalling purposes,or when the T855 is configured as a line controlled base station (refer to Section 4).1.5 CTCSS ConfigurationLinks PL230 & PL240 select various CTCSS options (refer to Section 1.7.2).

Whenthe transmitter is keyed, the coaxial relay is also energised.  When the relay is in its restposition, signals from the aerial are passed to the receiver and the demodulated outputis fed via 600 ohm lines to the RCU.The receiver is disabled when the transmitter is energised to prevent the receiver muteopening from RF due to lack of isolation in the relay, direct radiation or the noise skirt ofthe dual frequency link.Since the base station may be controlled via a 2-wire line and a 4-wire to 2-wire hybrid,there is a possibility of system oscillation if the receiver is not disabled during transmit.This occurs when the transmit energy enters the receiver and produces an audioresponse which can pass from the receive to the transmit audio part of the hybrid(impedance imbalance, etc).Figure 4.1   Basic ConfigurationFigure 4.2   Remote Line Controlled Base StationRF Out CoaxRelayDCKeyLogicTxEnableDC RelayControlRF InTx RxAntennaRx DisableTx AFRF Out CoaxRelayRF InTx RxAntennaHybridRx AFRemoteControlMicrophoneSpeakerPTT

These changes can be split into twogroups, mechanical and electrical, as described below.This procedure assumes you have already purchased the appropriate Series I conver-sion kit:• T855  -  T800-70-0055• T856  -  T800-70-0056• T857  -  T800-70-0057.If not, you should purchase one from your nearest Tait Dealer or Customer ServiceOrganisation before beginning the procedure.  It should take approximately 15-20 minutes per module to perform these steps.Mechanical These changes involve:• putting on a new front panel because of the differences inheight and width between a Series II and Series I panel;• adding D-range locating pins as the Series I rack requiresthem for alignment.Electrical These changes involve:• making sure there is pin compatibility for D-range 1 pin 7between the Series II module and the Series I rack frame;in Series I, pin 7 is allocated to audio 1 for the transmitter/exciter, and audio 2 for the receiver;• converting the exciter from rear RF output to front RF out-put;• disabling cyclic keying in the exciter.

Be very careful while doing this as the legsof the LED are very easy to break.9 Replace the covers.10 ProgrammingOnce you have carried out this conversion procedure, you will nolonger be able to program the T850 Series II module via D-range 1.In order to program the module now, you will need to use a program-ming module interface, such as the T800-01-0004.  This device is fittedwith a programming socket and can be connected to the module viaSK805 in the microcontroller section.  You will have to remove the topcover (closest to the handle) to gain access to SK805.Note:You may still be able to program the module by connectingthe T800-01-0004 to a T800-03-0000 auxiliary D-range fittedas D-range 2, but only if pins 8 (ground) and 12 (serial com)of D-range 2 are not used in the Series I configuration.
