4. Clone Mode
4-1. Outline
"Clone Mode" copies the transceiver data to another transceiver. The dealer can copy the transceiver data to another transceiver even without the use of a personal computer.

3-2. Connection procedure
1. Connect the TK-2202/2206 to the personal computer with the interface cable. 2. When the POWER is switched on, user mode can be entered immediately. When the PC sends a command, the radio enters PC mode. When data is transmitting from the transceiver, the red LED lights. When data is received by the transceiver, the green LED lights. Notes: The data stored in the personal computer must match the model type when it is written into the EEPROM. Change the TK-2202/2206 to PC mode, then attach the interface cable.

4-2. Example
The transceiver can copy the programming data to one or more 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 hold the [PTT] and [side2] keys while turning the transceiver power ON. 2. Wait for 2 seconds. The LED will light orange and the transceiver will announce "Clone". 3. Select a channel table number using Side1(increment channel table) and Side2(decrement channnel table) keys. 3

4. To switch the clone master to Clone mode, press and hold the [PTT] and [side2] keys while turning the transceiver power ON. 5. Wait for 2 seconds. The LED will light orange and the transceiver 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 will light green. When the clone master finishes sending data, a "confirmation" tone will sound. If data transmission fails while cloning, an "error" tone will sound from the Slave unit. 8. If the cloning fails, no data will be available in the Slave unit when 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 by repeating 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 used for 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 type TK-3207 transceivers will use Chinese. Other types English. Once a unit is set to be the Master, it cannot be a slave after the data has been transmitted. This protects the data in the Master unit. Electronic interface may cause a failure in data transfer during Wireless Clone, such as when waveforms or electromagnetics are being performed at the workbench. Clone mode can be used ONLY by the authorized service personnel. The Clone mode setting must be configured as "Disable" before being delivered to the end-user. To clone, replace the antenna from both the master transceiver and the slave transceiver with a dummy load. The transmit output power is automatically set to Low in Clone mode.

CIRCUIT DESCRIPTION
1. Frequency Configuration
The receiver utilizes double conversion. The first IF is 38.85 MHz and the second IF is 450 kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Fig. 1 shows the frequencies.

3) IF Amplifier Circuit
The first IF signal is passed through a four-pole monolithic crystal 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). The IF system IC provides a second mixer, second local oscillator, limiting amplifier, quadrature detector and RSSI (Received Signal Strength Indicator). The second mixer mixes the first IF signal with the 38.4MHz of the second local oscillator output (TCXO X1) and produces the second IF signal of 450kHz. The second IF signal is passed through the ceramic filter (CF201) to remove the adjacent channel signal. The filtered second IF signal is amplified by the limiting amplifier and demodulated by the quadrature detector with the ceramic discriminator (CD201). The demodulated signal is routed to the audio circuit.

Narrow and Wide settings can be made for each channel by switching the demodulation level. The WIDE (low level) and NARROW (high level) data is output 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 the IC201 detector output level is switched to maintain a constant output level during wide or narrow signals.

1) Front End (RF AMP)
The signal coming from the antenna passes through the transmit/receive switching diode circuit, (D103,D104,D105 and D106) passes through a BPF (L214 and L213), and is amplified 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 variable capacitors (D203,D204,D205 and D206). The input voltage to the variable capacitor is regulated by voltage output from the microprocessor (IC405).

The demodulated signal from IC201 goes to AF amplifier through IC301. The signal then goes through an AF volume control , and is routed to an audio power amplifier (IC302) where it is amplified and output to the speaker.

2) First Mixer
The signal from the front end is mixed with the first local oscillator signal generated in the PLL circuit by Q1 to produce a first IF frequency of 38.85 MHz. The resulting signal passes through the XF201 MCF to cut the adjacent spurious and provide the opitimun characteristics, such as adjacent frequency selectivity.

CIRCUIT DESCRIPTION
6) Squelch
Part of the AF signal from the IC enters the FM IC (IC201) again, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level. The DC signal from the FM IC goes to the analog port of the microprocessor (IC405). IC405 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value. To output sounds from the speaker, IC405 sends a high signal to the SP MUTE line and turns IC302 on through Q303,Q304,Q305,Q306 and Q316. (See Fig. 4)

2) VCO
The operating frequency is generated by Q4 in transmit mode and Q3 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D4 and D7 in transmit mode and D5 and D9 in receive mode). The RX pin is set high in receive mode causing Q5 turn on. The TX pin is set high in transmit mode. The outputs from Q3 and Q4 are amplified by Q6 and sent to the RF amplifiers.

7) Receive Signalling
(1) QT/DQT The output signal from FM IC(IC201) enters the microprocessor(IC405) through IC301. IC405 determines whether the QT or DQT matches the preset value, and controls the SP MUTE and the speaker output sounds according 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 unlock condition occurs, and the DC voltage obtained from C4,R5 and D1 causes the voltage applied to the microprocessor to go low. When the microprocessor detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal.

Fig. 4 AF amplifier and squelch
(3) DTMF The DTMF input signal from the FM IC (IC201) goes to IC301. The decoded information is then processed by the CPU.

4. Transmitter System 3. PLL Frequency Synthesizer
The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission.

1) Microphone Amplifier
The signal from the microphone passes through the IC301. When encoding DTMF, it is turned OFF for muting the microphone input signal by IC301. The signal passes through the Audio processor (IC301) for the maximum deviation adjustment, and goes to the VCO modulation input.

1) PLL
The 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 a fixed counter to produce an oscillator (VCO) output signal which is buffer amplified by Q2 then divided in IC1 by a programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal from the phase comparator in IC1. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 5)

Fig. 6 Microphone amplifier 2) Drive and Final Amplifier
The signal from the T/R switch (D101 is on) is amplified by the pre-drive (Q102) and the drive amplifier (Q103) to 50mW. The output of the drive amplifier is amplified by the RF power amplifier (Q106) to 5.0W (1W when the power is low). The RF power amplifier consists of two MOS FET stages. The output of the RF power amplifier is then passed through the harmonic filter (LPF) and antenna switch (D103 and D104) and applied to the antenna terminal.

5. Power Supply
There are four 5V power supplies for the microprocessor: 5M,5C,5R, and 5T. 5M for microprocessor is always output while the power is on. 5M is always output, but turns off when the power is turned off to prevent malfunction of the microprocessor. 5C is a common 5V and is output when SAVE is not set to OFF. 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) and its peripheral circuits. It controls the TX-RX unit. IC405 mainly performs the following: (1) Switching between transmission and reception by the PTT signal input. (2) Reading system, group, frequency, and program data from 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.

Fig. 7 Drive and final amplifier and APC circuit 3) APC Circuit
The APC circuit always monitors the current flowing through the RF power amplifier (Q106) and keeps a constant current. The voltage drop at R127, R128 and R129 is caused by the current flowing through the RF power amplifier and this voltage is applied to the differential amplifier IC101(1/2). IC101(2/2) compares the output voltage of IC101(1/2) with the reference voltage from IC405. The output of IC101(2/2) controls the VG of the RF power amplifier, drive amplifier and pre-drive amplifier to make both voltages the same. The change of power high/low is carried out by the change of the reference voltage.

1) Frequency Shift Circuit
The microprocessor (IC405) operates at a clock of 7.3728MHz. This oscillator has a circuit that shifts the frequency 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 internal spurious transmission modulated sound of a transceiver.

4) Encode Signalling
(1) QT/DQT QT,DQT data of the QTTCXO Line is output from pin 28 of the CPU. The signal passes through a low-pass CR filter and goes to the TCXO(X1). 10

The battery voltage is checked using by the microprocessor. The transceiver generates a warning tone when it falls below the warning voltage shown in the table. (1) The red LED blinks when the battery voltage falls below the voltage (1) shown in the table during transmission. Note: The transceiver checks the battery voltage during reception even when, in the FPU, the Battery Warning status function is set to "On TX" (default setting). However, the LED does not blink during reception. During transmission, the LED blinks to generate the warning tone of a low battery voltage. (2) The transceiver immediately stops transmission when the battery voltage falls below the voltage (2) shown in the table. A message tone beeps while the PTT switch is released.

The following parts are required for adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA terminal. Use an antenna connector adapter [SMA(f) BNC(f) or SMA(f) N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

Connect the power cable properly between the battery jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both. Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, between the power supply and the battery jig, especially while the transceiver transmits.

2. Repair Jig (Chassis)
Use jig (part No.: A10-4086-03) for repairing the TK-2202/ 2206. Place the TX-RX unit on the jig and fit it with screws. The jig facilitates the voltage check and protects the final amplifier FET when the voltage on the flow side of the TX-RX unit is checked during repairs.

Preparations for tuning the transceiver Before attempting to tune the transceiver, connect the unit to a suitable power supply. Whenever the transmitter is tuned, the unit must be connected to a suitable dummy load (i.e. power meter). The speaker output connector must be terminated with a 8 dummy load and connected to an AC voltmeter and an audio distortion meter or a SINAD measurement meter at all times during tuning.
