___________________________________________________________________________RF Technology T800 Page 51 OPERATING INSTRUCTIONS WARNINGChanges or modifications not expressly approved byRF Technology could void your authority to operate thisequipment. Specifications may vary from those given inthis document in accordance with requirements of localauthorities. RF Technology equipment is subject tocontinual improvement and RF Technology reserves theright to change performance and specification withoutfurther notice.1Operating Instructions1.1 Front Panel Controls and Indicators1.1.1 PTTA front-panel push-to-talk (PTT) button is provided to facilitate bench and field tests andadjustments. The button is a momentary action type. When keyed, audio from the line inputis disabled so that a carrier with sub-tone is transmitted. The front-panel microphone input isnot enabled in this mode, but it is enabled when the PTT line on that socket is pulled toground.1.1.2 LineThe LINE trimpot is accessible by means of a small screwdriver from the front panel of themodule. It is used to set the correct sensitivity of the line and direct audio inputs. It isfactory preset to give 60% of rated deviation with an input of 0dBm (1mW on 600Ωequivalent to 775mV RMS or about 2.2V peak-to-peak) at 1kHz. The nominal 60% deviationlevel may be adjusted by measuring between pins 6 and 1 on the test socket, and adjusting thepot. By this means an input sensitivity from approximately -30dBm to +10dBm may beestablished.An internal jumper provides a coarse adjustment step of 20dB. Between the jumper and thetrimpot, a wide range of input levels may be accommodated.1.1.3 POWER LEDThe PWR LED shows that the dc supply is connected to the receiver.1.1.4 TX LEDThe TX LED illuminates when the transmitter is keyed. It will not illuminate (and an Alarmcadence will be shown) if the synthesizer becomes unlocked, or the output amplifier supply isinterrupted by the microprocessor.

JP17 allows this. Normally JP17 is open circuit. Placinga link across it will bypass the low pass filter.In conjunction with this change, it sometimes may be necessary, depending on the type oftrunking controller used, to add a 100K resistor in the place reserved for R157.2.11 JP19: Alarm Output (Rev 4 or higher)The main audio transformer (T1), is connected to the Line IP1 and Line IP4 pins on P3.These two pins constitute the main audio input for the exciter. The centre taps of the audiotransformer, though, are brought out on Line IP2, and Line IP3. These can be used asalternate audio pins for larger signals, or to directly access the dc loop sense circuitry. JP19allows an alternate use for Line IP2 (pin 7 of P3). In the alternate position for JP19, theALARM signal (the signal that drives the ALARM LED itself) is connected to pin 7 of P3.The ALARM signal when asserted is low active; when unasserted, it pulls high to +9.4Vthrough an LED and a 680 ohm resistor.Condition PositionP3, pin 7 connects to center tap of transformer T1 1-2*P3, pin 7 connects to ALARM signal 2-32.12 JP22: Use Tone- as a Direct Digital Input (Rev 4 or higher)JP22 is normally shunted with a jumper, which connects Tone- on P3 (pin 18), as the negative leg of theTone input pair. Removing this jumper disconnects Tone- from this path and allows the use of theTone- pin to be used as a direct digital input. See also 2.9 - JP16: If this jumper is removed, then JP16should be in the alternative position (Direct Tone Input).2.13 JP23: Connection of DMTX Board (Rev 4 or higher)When a DMTX board is connected to an exciter, there is provision for digital or audio modulation of thereference osciallator and the VCO. The digital signal is input via the DB9 rear connector and the audioinput signal is via the Line inputs on the standard DB25 rear panel connector.

___________________________________________________________________________RF Technology T800 Page 135 CIRCUIT DESCRIPTION 5.1 VCO Section5Circuit DescriptionThe following descriptions should be read as an aid to understanding the block and schematicdiagrams given in the appendix of this manual.5.1 VCO SectionThe Voltage Controlled Oscillator uses a bipolar junction FET Q19 which oscillates at therequired transmitter output frequency. Varactor diodes D25 and D26 are used by the PLLcircuit to keep the oscillator on the desired frequency. A second varactor diode D3 is used tofrequency modulate the VCO. Transistor Q20 is used as an active filter to reduce the noiseon the oscillator supply voltage.The VCO is keyed ON by the microcontroller through Q10. It is keyed ON when any of thePTT inputs are active and OFF at all other times.The VCO output is amplified and buffered by monolithic amplifiers MA2 and MA3 beforebeing fed to the PLL IC U6.Amplifiers MA1, MA4 and MA5 increase the VCO output to approximately 10 mW to drivethe power amplifier. MA1 is not switched on until the PLL has locked and had time to settle.This prevents any momentary off channel transmission when the transmitter is keyed.5.2 PLL SectionThe frequency reference for the synthesiser is a crystal oscillator using transistors Q26 andQ27 and crystal Y3. The temperature stability is better than 5 ppm and it can be synchronisedto an external reference for improved stability. External reference option board 11/9119 isrequired when using an external reference.A positive temperature coefficient thermistor, XH1, is used in versions intended for operationdown to -30 degrees Celsius. The thermistor heats the crystal's case to maintain itstemperature above -10 degrees thus extending the oscillator stability of 5 ppm down to -30degrees ambient.Varactor diodes D27-30 are used to frequency modulate the oscillator. The processed transmitaudio signal from U7b varies the diodes bias voltage to modulate the reference frequency.This extends the modulation capability down to a few Hz for sub-audible tones and digitalsquelch codes. A two point modulation scheme is used with the audio also being fed to theVCO to modulate the higher audio frequencies.The 12.8 MHz output of Q27 is amplified by Q28 and Q29 to drive the reference input of thePLL synthesiser IC U6. This IC is a single chip synthesiser which includes a 1.1 GHz pre-scaler, programmable divider, reference divider and phase/frequency detector. The frequencydata for U6 is supplied via a serial data link by the microcontroller.
___________________________________________________________________________RF Technology T800 Page 145.3 Power Amplifier 5 CIRCUIT DESCRIPTIONThe phase detector output signals of U6 are used to control two switched current sources. Theoutput of the positive and negative sources Q3 and Q6, produce the tuning voltage which issmoothed by the loop filter components to bias the V.C.O. varactor diode D3.5.3 Power AmplifierThe 10 mW output from the main board connects to the power amplifier board through a shortminiature 50Ω coaxial cable.Q2 on the power amplifier board increases the signal to approximately200mW. The bias ofQ2 is controlled by Q1 and the power leveling circuitry to adjust the drive to the outputmodule U2.U2 increases the power from the driver to 30 watts before it is fed to the directional coupler,low pass filter and output connector. The directional coupler detects the forward and reversepower components and provides proportional dc voltages which are amplified by U1a andU1b.The forward power voltage from U1a and U1b are compared to the present DC referencevoltage from RV1. The difference is amplified by U1c, Q3 and Q4. The resulting controlvoltage supplies Q2 through R10, R12 and completes the power levelling control loop.5.4 Temperature ProtectionThermistor RT1 on the power amplifier board is used to sense the case temperature of theoutput module U2. If the case temperature rises above 90 degrees C, the voltage across RT1will increase and transistor Q5 will be turned on. This reduces the dc reference voltage to thepower regulator which inturn reduces the outpower by 6-10dB.5.5 600Ω Line InputThe 600Ω balanced line input connects to line isolation transformer T1. T1 has two 150Ωprimary windings which are normally connected in series for 600Ω lines. The dual primarywindings can be used to provide DC loop PTT signaling or a 2/4 wire hybrid connection. Allfour leads are available at the rear panel system connector.The secondary of T1 can be terminated with an internal 600Ω load through JP5 or left un-terminated in high impedance applications.5.6 Direct Coupled Audio InputA high impedance (10kΩ) direct AC coupled input is available at the system connector. Thedirect coupled input connects to U9a which is configured as a unity gain bridge amplifier.The bridge configuration allows audio signal inversion by interchanging the positive andnegative inputs and minimizes ground loop problems. Both inputs should be connected, withone lead going to the source output pin and the other connected to the source audio ground.
___________________________________________________________________________RF Technology T800 Page 155 CIRCUIT DESCRIPTION 5.7 Local Microphone Input5.7 Local Microphone InputThe local microphone input is provided for use with a standard low impedance dynamicmicrophone. The microphone output is amplified by U9a before connecting to analogueswitch U10a. U10b inverts the local microphone PTT input to switch U10a ON when themicrophone PTT button is pressed. U10a is OFF at all other times.The local microphone audio has priority over the other inputs. Activation of the localmicrophone PTT input switches OFF the audio from the line or direct inputs through D16 andU10c5.8 CTCSS and Tone FilterThe CTCSS encoder module H1, under control of the main microprocessor U13, can encodeall 38 EIA tones and (on some models) additional commonly-used tones.The tone output of H1 connects to jumper JP8 which is used to select either H1 or an externaltone source. The selected source is coupled to U9c which is a balanced input unity gainamplifier. The buffered tone from U9c is fed to 300 Hz low pass filter U7c.On Rev 4 or later revisions, the low pass filter can be by passed by inserting a jumper ontoJP17.RV3, the tone deviation trimmer, is used to adjust the level of the tone from U7c before it iscombined with the voice audio signal in the summing amplifier U7a.Back to back diodes D4 and D5 limit the maximum tone signal amplitude to preventexcessive tone deviation when external tone sources are used.The subtone amplifier, filter and limiter can be bypassed on Rev 4 or later exciters byremoving the link from JP22 and moving the link in JP16 to the alternate position.5.9 Audio Signal ProcessingJumper JP4 selects either the line or direct input source. The selected source is thenconnected to JP6. JP6 can be removed to provide 20 dB attenuation when the input level isabove 10 dBm to expand the useful range of the line level trimmer RV4. The wiper of RV4 iscoupled to the input of the input amplifier U9d. U9d provides a voltage gain of ten beforeconnecting to the input of analogue switch U10c.The outputs of U10a and U10c are connected to the frequency response shaping networksC52, R133 (for 750µs pre-emphasis) and C61, R55 (for flat response). JP7 selects the pre-emphasized or flat response.The audio signal is further amplified 100 times by U7d. U7d also provides the symmetricalclipping required to limit the maximum deviation. The output level from U7d is adjusted byRV1, the deviation adjustment, before being combined with the tone audio signal in thesumming amplifier U7a.
___________________________________________________________________________RF Technology T800 Page 165.10 PTT and DC Remote Control 5 CIRCUIT DESCRIPTIONThe composite audio from U7a is fed through the 3Khz low pass filter U7b. When the linkson JP23 are in their default state, the filtered audio is coupled to the TCXO voltage tuninginput and the modulation balance trimmer RV2. RV2, R99 and R98 attenuate the modulationsignal before applying it to the VCO via varactor D3.When DMTX board option is required, Jumper JP23 allows the audio paths to be re-routed.The DMTX board provides for an external digital modulation input signal. When the twolinks on JP23 are positioned in the middle of the 6 pin header, the audio from the exciter ispassed to the DMTX board via pin 5 of JP15, where the signal is conditioned and thenreturned from the DMTX board via pin 2 of JP15, and passed to the two modulation points.RV2 adjusts level of the audio used to modulate the VCO. This primarily effects the deviationof audio frequencies above 500 Hz. RV2 is used to balance the high and low frequencydeviation to obtain a flat frequency response relative to the desired characteristic.5.10 PTT and DC Remote ControlTwo main PTT inputs are provided. The first, a direct logic level input, is connected to pin 3of the system connector. The transmitter can be keyed by applying a logic low or ground onpin 3. Pin 3 connects to the PTT logic and microprocessor through D10.DC current loop control can be used for remote PTT operation. The current loop can beconfigured by JP9, JP10 and JP11 for use with either a remote free switch or a remoteswitched source.Opto-isolator ISO1 is used to isolate the loop current signal from the transmitter PTT logic.The loop current passes through the input of ISO1 and the output of ISO1 connects to the PTTlogic.A bridge consisting of diodes D6, D8, D9 and D14 ensures correct operation regardless of thecurrent polarity. Q17 limits the current and D7 limits the voltage input of ISO1. Any lowvoltage current source capable of providing 2mA at 4V or switching circuit with less than4.8k¿ loop resistance can be used to switch the DC loop.The test PTT button on the front panel and the local microphone PTT button will also key thetransmitter. Both of these also mute the line audio input. The microphone line also enablesthat audio input.A DMTX board can also cause the exciter to key up. When TX (or TTL_TX) signal isreceived by the DMTX board, it pulls pin 6 of JP15 low, which in turn asserts thePTT_WIRE-OR signal, causing the microprocessor (U13) to key the exciter up.5.11 Microprocessor ControllerThe microprocessor controller circuit uses a single-chip eight bit processor and severalsupport chips. The processor U13 includes non-volatile EE memory for channel frequencies,tones, and other information. It also has an asynchronous serial port, a synchronous serialport and an eight bit analogue to digital converter.
___________________________________________________________________________RF Technology T800 Page 175 CIRCUIT DESCRIPTION 5.12 Voltage RegulatorThe program is stored in U5, a CMOS EPROM. U4 is an address latch for the low orderaddress bits. U2 is used to read the channel select lines onto the data bus. U11 is an addressdecoder for U5 and U2. U3 is a supervisory chip which keeps the processor reset unless the+5 Volt supply is within operating limits. U1 translates the asynchronous serial port data tostandard RS232 levels.The analogue to digital converter is used to measure the forward and reverse power, tuningvoltage and dc supply voltage.If the processor detects that the PTT_WIRE_OR signal is asserted low, it will attempts to keythe exciter up. If will first attempt to key the VCO through Q10, and if the LD pin goes high,it will switch the 9.2 Volt transmit line through Q14 and Q16. asserting Q16 has the effect ofalso asserting the yellow Tx LED (D12) on the front panel, enabling the local 25W poweramplifier, and causing the T/R Relay output to be pulled low. D24 is 30 volt zener whichprotects Q25 from both excessive voltages or reverse voltages.Should there be a problem with either the tuning volts, or the battery voltage, the VCOlocking, the forward power, or the reverse power, the microprocessor will assert the ALARMLED, through Q1. Depending on the setting of Jumper JP19, the ALARM signal can bebrought out on pin 7 of P3.5.12 Voltage RegulatorThe dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. The seriespass transistor Q23 is driven by error amplifiers Q8 and Q18. Q9 is used to start up theregulator and once the circuit turns on, it plays no further part in the operation.The +5 Volt supply for the logic circuits is provided by an integrated circuit regulator U14which is run from the regulated 9.4 Volt supply.Jumper JP18 is not normally fitted to the board, and is bridged with a 12mil track on thecomponent side of the board. It is provided so that the 9.4V load can be isolated from thesupply by the service department to aid in fault finding.Jumpers JP20 and JP21 are also not normally fitted on the board, and are usually bridged witha 12mil track on the component side. They allow U14 to be isolated from its input, or itsoutput or both.6Field Alignment ProcedureThe procedures given below may be used to align the transmitter in the field. Normally,alignment is only required when changing operating frequencies, or after componentreplacement.The procedures below do not constitute an exhaustive test or a complete alignment of themodule, but if successfully carried out are adequate in most circumstances.

If in doubt, allow 1.5dBcable and connector losses, and assume that the maximum rated power is 15W. This means no more than 10Wat the end of a 1m length of test cable. This pessimistic procedure is safe on all models manufactured at the timeof writing.
___________________________________________________________________________RF Technology T800 Page 217SPECIFICATIONS 7.1 Overall Description7SPECIFICATIONS7.1 Overall DescriptionThe transmitter is a frequency synthesized, narrow band FM unit, normally used to drive a 50watt amplifier. It can also be used alone in lower power applications.Various models allow 2-25W of output power to be set across a number of UHF frequencybands. All necessary control and 600Ω line interface circuitry is included.7.1.1 Channel CapacityAlthough most applications are single channel, it can be programmed for up to 100 channels,numbered 0 - 99. This is to provide the capability of programming all channels into all of thetransmitters used at a given site. Where this facility is used in conjunction with channel-setting in the rack, exciter modules may be “hot-jockeyed” or used interchangeably. This canbe convenient in maintenance situations.7.1.2 CTCSSFull EIA sub-tone capability is built into the modules. The CTCSS tone can be programmedfor each channel. This means that each channel number can represent a unique RF and tonefrequency combination.7.1.3 Channel ProgrammingThe channel information is stored in non-volatile memory and can be programmed via thefront panel test connector using a PC and RF Technology software.7.1.4 Channel SelectionChannel selection is by eight channel select lines. These are available through the rear panelconnector. Internal presetting is also possible. The default (open-circuit) state is to selectchannel 00.A BCD active high code applied to the lines selects the required channel. This can besupplied by pre-wiring the rack connector so that each rack position is dedicated to a fixedchannel. Alternatively, thumb-wheel switch panels are available.7.1.5. MicroprocessorA microprocessor is used to control the synthesizer, tone squelch, PTT function and facilitatechannel frequency programming. With the standard software, RF Technology modules alsoprovide fault monitoring and reporting.
