CIRCUIT DESCRIPTION

1. Frequency configurationThe TM-V708A has an individual VCO and PLL unit for

both VHF and UHF bands. Using these separate VCO andPLL circuit, it can receive 2 separate bands at the same time.Also, you can perform the full-duplex operation.

The VHF VCO is used for the following functions:(i) VHF transmission(ii) The first local oscillator for the main band (VHF) reception.(ii i)The first local oscillator for the sub band (UHF)

reception (doubled).

The UHF VCO is used for the following functions:(i) UHF transmission(ii) The first local oscillator for the main band (UHF) reception.(ii i)The first local oscillator for the sub band (VHF)

reception (halved).

The PLL reference frequency is generated by a 12.8MHzcrystal oscillator connected to the VHF and UHF PLL ICs. Thisreference frequency is used for both PLL circuits.

The second local oscillator for the VHF band uses thetripled 12.8MHz reference oscillator frequency. The45.05MHz second local oscillator for the UHF band isgenerated by the IF IC crystal oscillator circuit.

The signalpasses through the MCF (XF100), is amplified by the IFamplifier (Q112) and enters the IF IC (IC100). Then the signalis converted to the 450kHz second IF signal by the secondlocal oscillator, which is tripled 12.8MHz (Lower heterodyne).Then it is detected to generate an audio signal.

2-2. Main UHF ReceiverThe incoming signal from the antenna passes through a

filter circuit and enters the RF amplifier (Q508). The amplifiedsignal passes through the SAW filter (L517), is amplified byanother RF amplifier (Q505). Then it passes through the LCfilter (L508) and enters the single balanced mixer (Q501,Q502). The frequency of the signal is converted by the first

local oscillator (Lower heterodyne) to generate a 45.05MHzfirst IF signal. The signal passes through the MCF (XF400), isamplified by the IF amplifier (Q406) and enters the IF IC(IC400).

KEY INPUT INTERRUPT CIRCUIT

6-2. Speaker Switching CircuitThere are two speaker jacks, J801 and J802. The AF

signals can be output in various combinations matching theinternal speakers.

When no external speaker is connected to J801, Pins 5 ofthe multiplexer (IC807, IC808) go low, the AF signals AO 0and AO 1 are added and input to the power amp (IC806).

When an external speaker is connected to J801, Pins 5 ofthe multiplexer (IC18) go high and AO 0 and AO 1 are inputseparately to the power amp.

6-3. Microphone Key InputThe microphone UP/DOWN and function keys are

connected to the microprocessor analog input. The voltagewhen a key is ON operates the corresponding function. Also,the key input interrupt circuit is for switching the power ON/OFF with the microphone. When the DOWN, MR, and PF

keys are pressed, an interrupt is generated and themicroprocessor is awoken from stop mode. However, withthe TM-V708A, the power ON/OFF switch function can beregistered to the PF key on the microphone.

CIRCUIT DESCRIPTION

7. Data Terminal and Peripheral CircuitsJ700 (data terminal) is the data communications terminal

on the front. It handles transmission control, data input/output, and squelch signals.

There are two data communications modes: 9600bpsmode and 1200bps mode. 9600bps mode communicationsare FAST FM mode of SSTV, GMSK and G3RUH packetcommunications. Unlike with 1200bps AFSK, with this typeof high-speed modulation, frequency modulation is carriedout after the digital base band signals (rectangular wave) arepassed through a band limiting filter. For 9600bps GMSK forexample, compared to 4800Hz signals (nearly sine wavesignals passed through a filter), these signals have a hissingsound like digital modulation when listened to by ear.

Fig. 16 Transmission signals

Different types of modulation, such as GMSK and G3RUH,are distinguished by the type of band limiting filter.

7-1. Transmission signalsTransmission modulation signals enter from PKD of the

data tenninals (J700). The path to the modulation depends onwhether communications are 1200bps or 9600bps mode.

For 1200bps mode, the transmission modulation signalspass through the analog switch (IC803), and are input toIC801 (Pin 6). The signals pass through the pre-emphasis(Q801, Q802), are adjusted by the electronic volume, and areinput to the VCO.

For 9600bps mode, the transmission modulation signalspass through IC803 and amplified by the tone amp (IC802).Then it is adjusted by the electronic volume, and are input tothe VCO.

The frequency shift depends on the input signal level, sothere is an amplitude limiting circuit (D702, D703) to hold thesignal below 4 Vp-p to avoid extreme shifts.

Thanks to this circuit, the PKD signal does not go above 4Vp-p and the frequency shift does not fluctuate extremely.

7-2. Reception signalsPR9 is the 9600bps data communications reception

output. It outputs the FM detection circuit output (RD signals)through a buffer amp (Q700). These signals are alwaysoutput whether the squelch is open or closed.

PR1 is the 1200bps data communications receptionoutput. It outputs the FM detection circuit output (RA signals)through a buffer amp (Q701). Output is controlled with thecross point switch (IC702) according to whether squelch isopen or closed.

7-3. Squelch signal output circuitThe squelch circuits is input to the TNC to prevents

conflicts from occurring between simultaneous receivemode and t ransmit mode t ra f f ic dur ing packetcommunications. (only during 1200bps) The signal is outputfrom Pin 15 of IC703 to the data terminal. The logic is asshown in the Table below.

8. Panel Section (LCD ASSY: B38-0829-05)The panel section controls serial communications with the

main unit control section, the key input circuit, the displaycircuit, and the dimmer circuit through the microprocessor(IC4).

8-1. Serial communications circuitA buffer amp is inserted in order to protect the

microprocessor ports.

8-2. Key, Volume Input circuitCircuits to operate the panel section keys are connected

to each microprocessor port. The PSW key is pulled up andthe other keys are pulled up with software within themicroprocessor. Rotary encoder operating circuits areconnected directly to the microprocessor. The control dividesthe power supply voltage, reads the A/D port of themicroprocessor, and transfers that data to the main unit.

8-3. Display circuitThe TM- V708A display section is a 188x54-dot full-dot

matrix LCD controlled by two LCD. As shown is Figure 17,the master IC (IC2) side is connected to 22 common dots and88 segment dots and the stave IC (IC1) side is connected to33 common dots and 100 segment dots. The LCD drivevoltage is obtained by raising the power supply voltage (5V)within the IC.

8-4. Dimmer circuitThe dimmer circuit switches the lamp brightness to one of

four levels or OFF. (See table7) The current flowing to theLEDs is varied by selecting resistors from R8 to R14.
