4-1. Outline

"Clone Mode" copies the transceiver data to anothertransceiver.

The dealer can copy the transceiver data to anothertransceiver even without the use of a personal computer.

4-2. Example

The transceiver can copy the programming data to one ormore transceivers via RF communication.

The clone master and clone slave/s must be in Clone mode.

4-3. Operation

1. To switch the clone slave/s to Clone mode, press and holdthe [PTT] and [side2] keys while turning the transceiverpower ON.

2. Wait for 2 seconds. The LED will light orange and thetransceiver will announce "Clone".

3. Select a channel table number using Side1(incrementchannel table) and Side2(decrement channnel table) keys.

4. To switch the clone master to Clone mode, press and holdthe [PTT] and [side2] keys while turning the transceiverpower ON.

5. Wait for 2 seconds. The LED will light orange and thetransceiver will announce "Clone".

6. Select the same channel table number as the clone slave/s.7. Press [PTT] on the clone master to begin data transmission.

When the clone slave starts to receive data, the LED willlight green.When the clone master finishes sending data, a"confirmation" tone will sound.If data transmission fails while cloning, an "error" tone willsound from the Slave unit.

8. If the cloning fails, no data will be available in the Slave unitwhen it is returned to User mode.

9. When the cloning is successful, the Slave unit's "Scan" and"Key lock" functions will return to their default values (Scan= OFF, Key lock = OFF).

Notes:

• The dealer can clone data to two or more transceivers byrepeating the above procedures.

• If the transceivers Clone Mode is configured as "Disabled",the transceiver cannot enter Clone mode.

• The table shown below will cover the frequency tables usedfor wireless cloning.

• Clone mode cannot be entered in battery low state.• A unit cannot be a "Master Unit" if it is unprogrammed. If

[PTT] is pressed, an "error" tone will sound.• The language used in cloning depends on the "Model type"

setting, not the FPU setting. C, C2, C5 and C6 typeTK-3207 transceivers will use Chinese. Other types English.

• Once a unit is set to be the Master, it cannot be a slaveafter the data has been transmitted. This protects the datain the Master unit.

• Electronic interface may cause a failure in data transferduring Wireless Clone, such as when waveforms orelectromagnetics are being performed at the workbench.

• Clone mode can be used ONLY by the authorized servicepersonnel.

• The Clone mode setting must be configured as "Disable"before being delivered to the end-user.

• To clone, replace the antenna from both the mastertransceiver and the slave transceiver with a dummyload.

• The transmit output power is automatically set to Lowin Clone mode.

5) Audio Amplifier CircuitThe demodulated signal from IC201 goes to AF amplifierthrough IC301.The signal then goes through an AF volume control , andis routed to an audio power amplifier (IC302) where it isamplified and output to the speaker.

Fig. 3 Wide/Narrow switching circuit

CIRCUIT DESCRIPTION

1. Frequency Configuration

The receiver utilizes double conversion. The first IF is 38.85MHz and the second IF is 450 kHz. The first local oscillatorsignal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessaryfrequencies. Fig. 1 shows the frequencies.

Fig. 1 Frequency configuration

1) Front End (RF AMP)The signal coming from the antenna passes through thetransmit/receive switching diode circuit, (D103,D104,D105and D106) passes through a BPF (L214 and L213), and isamplified by the RF amplifier (Q205).The resulting signal passes through a BPF (L209 and L211)and goes to the mixer. These BPFs are adjusted by variablecapacitors (D203,D204,D205 and D206). The input voltageto the variable capacitor is regulated by voltage output fromthe microprocessor (IC405).

2) First MixerThe signal from the front end is mixed with the first localoscillator signal generated in the PLL circuit by Q1 toproduce a first IF frequency of 38.85 MHz.The resulting signal passes through the XF201 MCF to cutthe adjacent spurious and provide the opit imuncharacteristics, such as adjacent frequency selectivity.

Fig. 2 Receiver section

2. Receiver

The frequency configuration of the receiver is shown in Fig. 2.

3) IF Amplifier Circuit

The first IF signal is passed through a four-pole monolithiccrystal filter (XF201) to remove the adjacent channel signal.The filtered first IF signal is amplified by the first IF amplifier(Q203) and then applied to the lF system IC (IC201). TheIF system IC provides a second mixer, second localoscillator, limiting amplifier, quadrature detector and RSSI(Received Signal Strength Indicator). The second mixermixes the first IF signal with the 38.4MHz of the secondlocal oscillator output (TCXO X1) and produces the secondIF signal of 450kHz.The second IF signal is passed through the ceramic filter(CF201) to remove the adjacent channel signal. The filteredsecond IF signal is amplified by the limiting amplifier anddemodulated by the quadrature detector with the ceramicdiscriminator (CD201). The demodulated signal is routedto the audio circuit.

4) Wide/Narrow Switching Circuit

Narrow and Wide settings can be made for each channelby switching the demodulation level.The WIDE (low level) and NARROW (high level) data isoutput from IC405, pin 45.When a WIDE (low level) data is received, Q202 turn on.When a NARROW (high level) data is received, Q202 turn off.Q202 turns on/off with the Wide/Narrow data and theIC201 detector output level is switched to maintain aconstant output level during wide or narrow signals.

CIRCUIT DESCRIPTION

6) SquelchPart of the AF signal from the IC enters the FM IC (IC201)again, and the noise component is amplified and rectifiedby a filter and an amplifier to produce a DC voltagecorresponding to the noise level.The DC signal from the FM IC goes to the analog port ofthe microprocessor (IC405). IC405 determines whetherto output sounds from the speaker by checking whetherthe input voltage is higher or lower than the preset value.To output sounds from the speaker, IC405 sends a highsignal to the SP MUTE line and turns IC302 on throughQ303,Q304,Q305,Q306 and Q316. (See Fig. 4)

7) Receive Signalling(1) QT/DQTThe output signal from FM IC(IC201) enters themicroprocessor(IC405) through IC301. IC405 determineswhether the QT or DQT matches the preset value, andcontrols the SP MUTE and the speaker output soundsaccording to the squelch results.

(2) MSK (Fleet Sync)The MSK input signal from the FM IC goes to pin 31 of IC 301.The signal is demodulated by MSK demodulator in IC 301.The demodulated data goes to the CPU for processing.

3) Unlock Detector

If a pulse signal appears at the LD pin of IC1, an unlockcondition occurs, and the DC voltage obtained from C4,R5and D1 causes the voltage applied to the microprocessorto go low. When the microprocessor detects this condition,the transmitter is disabled, ignoring the push-to-talk switchinput signal.

4. Transmitter System

1) Microphone Amplifier

The signal from the microphone passes through the IC301.When encoding DTMF, it is turned OFF for muting themicrophone input signal by IC301.The signal passes through the Audio processor (IC301) forthe maximum deviation adjustment, and goes to the VCOmodulation input.

(3) DTMFThe DTMF input signal from the FM IC (IC201) goes toIC301. The decoded information is then processed by theCPU.

3. PLL Frequency SynthesizerThe PLL circuit generates the first local oscillator signal for

reception and the RF signal for transmission.

1) PLLThe frequency step of the PLL circuit is 2.5,5,6.25 or 7.5kHz.A 12.8MHz reference oscillator signal is divided at IC1 by afixed counter to produce an oscillator (VCO) output signalwhich is buffer amplified by Q2 then divided in IC1 by aprogrammable counter. The divided signal is compared inphase with the 5 or 6.25kHz reference signal from the phasecomparator in IC1. The output signal from the phasecomparator is filtered through a low-pass filter and passedto the VCO to control the oscillator frequency. (See Fig. 5)

2) VCOThe operating frequency is generated by Q4 in transmitmode and Q3 in receive mode. The oscillator frequency iscontrolled by applying the VCO control voltage, obtainedfrom the phase comparator, to the varactor diodes (D4 andD7 in transmit mode and D5 and D9 in receive mode). TheRX pin is set high in receive mode causing Q5 turn on.The TX pin is set high in transmit mode. The outputs fromQ3 and Q4 are amplified by Q6 and sent to the RF amplifiers.

CIRCUIT DESCRIPTION

Fig. 6 Microphone amplifier

Fig. 7 Drive and final amplifier and APC circuit

3) APC Circuit

The APC circuit always monitors the current flowing throughthe RF power amplifier (Q106) and keeps a constant current.The voltage drop at R127, R128 and R129 is caused by thecurrent flowing through the RF power amplifier and thisvoltage is applied to the differential amplifier IC101(1/2).IC101(2/2) compares the output voltage of IC101(1/2) withthe reference voltage from IC405. The output of IC101(2/2)controls the VG of the RF power amplifier, drive amplifierand pre-drive amplifier to make both voltages the same.The change of power high/low is carried out by the changeof the reference voltage.

4) Encode Signalling

(1) QT/DQTQT,DQT data of the QTTCXO Line is output from pin 28 ofthe CPU. The signal passes through a low-pass CR filterand goes to the TCXO(X1).

2) Drive and Final Amplifier

The signal from the T/R switch (D101 is on) is amplified bythe pre-drive (Q102) and the drive amplifier (Q103) to 50mW.The output of the drive amplifier is amplified by the RF poweramplifier (Q106) to 5.0W (1W when the power is low). TheRF power amplifier consists of two MOS FET stages. Theoutput of the RF power amplifier is then passed throughthe harmonic filter (LPF) and antenna switch (D103 andD104) and applied to the antenna terminal.

The QT,DQT data of the QTVCO Line is output from pin 24of the CPU. The signal passes through a low pass CR filter,mixes with the audio signal, and goes to the VCO modulationinput. TX deviation is adjusted by the CPU.

(2) DTMFHigh-speed data is output from pin 2 of the CPU. The signalpasses through a low-pass CR filter, and provides a TX andSP out tone, and is then applied to the audio processor(IC301). The signal is mixed with the audio signal and goesto the VCO.TX deviation is adjusted by the CPU.

(3) MSK (Fleet Sync)Fleet Sync utilizes 1200bps and 2400bps MSK signal isoutput from pin 6 of IC301. And is routed to the VCO.When encoding MSK, the microphone input signal is muted.

5. Power Supply

There are four 5V power supplies for the microprocessor:5M,5C,5R, and 5T. 5M for microprocessor is always outputwhile the power is on. 5M is always output, but turns off whenthe power is turned off to prevent malfunction of themicroprocessor.

5C is a common 5V and is output when SAVE is not set toOFF.

5R is 5V for reception and output during reception.5T is 5V for transmission and output during transmission.

6. Control Circuit

The control circuit consists of a microprocessor (IC405) andits peripheral circuits. It controls the TX-RX unit. IC405 mainlyperforms the following:

(1) Switching between transmission and reception by thePTT signal input.

(2) Reading system, group, frequency, and program datafrom the memory circuit.

(3) Sending frequency program data to the PLL.(4) Controlling squelch on/off by the DC voltage from the

squelch circuit.(5) Controlling the audio mute circuit by the decode data input.(6) Transmitting tone and encode data.

1) Frequency Shift Circuit

The microprocessor (IC405) operates at a clock of7.3728MHz. This oscillator has a circuit that shifts thefrequency by BEAT SHIFT SW (Q407,Q408).A beat sound may be able to be evaded from generation if“Beat Shift” is set to ON when it is generated in the internalspurious transmission modulated sound of a transceiver.
