5. Clone Mode

5-1. 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.

5-2. ExampleThe transceiver can copy the programming data to one

or more transceivers via RF communication.The clone source and clone target/s must be in Clone

mode.

5-3. Operation1. To switch the clone target/s to Clone mode, press and

hold the [PTT] and [Side2] keys while turning the trans-ceiver 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 Lock (increment channel table) and Scan(decrement channnel table) keys.

4. To switch the clone source to Clone mode, press and hold the [PTT] and [Side2] keys while turning the trans-ceiver 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 tar-get/s.

7. Press [PTT] on the clone source to begin data transmis-sion.

When the clone target starts to receive data, the LED will light green.

When the clone source fi nishes sending data, a “confi r-mation” tone will sound.

If data transmission fails while cloning, an “error” tone will sound from the target unit.

8. If the cloning fails, no data will be available in the target unit when it is returned to User mode.

9. When the cloning is successful, the target unit’s “Scan” function will return to their default values (Scan = 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 “Dis-

abled”, 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 “Source Unit” if it is unprogrammed.

If [PTT] is pressed, an “error” tone will sound.• Once a unit is set to be the source, it cannot be a target

after the data has been transmitted. This protects the data in the source unit.

• If the target unit is cloned successfully, it will return to User Mode.

• If the target unit is not cloned successfully, the led will remain Orange.

Fig. 2 Receiver section

■ Front End (RF AMP)The signal coming from the antenna passes through thetransmit/receive switching diode circuit, (D103, D104,

D106 and D122) passes through a BPF (L229 and L228), and is amplifi ed by the RF amplifi er (Q205).

The resulting signal passes through a BPF (L214, L212 and L211) and goes to the mixer (Q204). These BPFs are adjusted by variable capacitors (D203, D204, D205, D206 and D210). The input voltage to the variable capacitor is reg-ulated by voltage output from the micro control unit (MCU) (IC405).

■ First MixerThe signal from the front end is mixed with the fi rst local

oscillator signal generated in the PLL circuit by Q3 to pro-duce a fi rst IF frequency of 38.85MHz.

The resulting signal passes through the XF201 MCF to cut the adjacent spurious and provide the opitimun charac-teristics, such as adjacent frequency selectivity.

■ IF Amplifi er CircuitThe fi rst IF signal is passed through a four-pole mono-

lithic crystal fi lter (XF201) to remove the adjacent channel signal.

The fi ltered fi rst IF signal is amplifi ed by the fi rst IF ampli-fi er (Q203) and then applied to the lF system IC (IC201). The IF system IC provides a second mixer, second local oscilla-tor, limiting amplifi er, quadrature detector and RSSI (Received Signal Strength Indicator). The second mixer mixes the fi rst IF signal with the 38.4MHz of the second local oscillator output (Q1) and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic fi lter (CF201) to remove the adjacent channel signal. The fi ltered 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.

■ Audio Amplifi er CircuitThe demodulated signal from IC201 goes to AF amplifi er

through IC301.The signal then goes through an AF volume control, and

is routed to an audio power amplifi er (IC302) where it is am-plifi ed and output to the speaker.

■ SquelchPart of the AF signal from the IC enters the FM IC (IC201)

again, and the noise component is amplifi ed and rectifi ed by a fi lter and an amplifi er to produce a DC voltage correspond-ing to the noise level.

The DC signal from the FM IC goes to the analog port of the MCU (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. 3)

■ Receive Signaling

• QT/DQTThe output signal from FM IC (IC201) enters the MCU

(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 re-sults.

3. PLL Frequency Synthesizer

The PLL circuit generates the fi rst local oscillator signal for reception and the RF signal for transmission.

■ PLLThe frequency step of the PLL circuit is 5 or 6.25kHz.A 12.8MHz reference an oscillator signal is divided at IC1

by a fi xed counter to produce oscillator (VCO) output signal which is buffer amplifi ed by Q2 then divided in IC1 by a pro-grammable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal from the phase com-parator in IC1. The output signal from the phase comparator is fi ltered through a low-pass fi lter and passed to the VCO to control the oscillator frequency. (See Fig. 4)

■ VCOThe 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 (D2, D4, D6 and D7 in transmit mode and D3, D5, D8 and D9 in re-ceive 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 amplifi ed by Q6 and sent to the RF am-plifi ers.

■ Unlock DetectorIf 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 MCU (IC405) to go low. When the MCU detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal.

pre-drive (Q101) to 50mW.The output of the drive amplifi er is amplifi ed by the RF

power amplifier (Q102 and Q103) to 2W (1W when the power is low). The RF power amplifi er consists of two MOS FET stages. The output of the RF power amplifi er is then passed through the harmonic fi lter (LPF) and antenna switch (D103 and D122) and applied to the antenna terminal.

■ APC CircuitThe APC circuit always monitors the current flow-

ing through the RF power amplifi er (Q102 and Q103) and keeps a constant current. The voltage drop at R127, R128 and R129 is caused by the current fl owing through the RF power amplifi er and this voltage is applied to the differential amplifi er IC101 (1/2).

CIRCUIT DESCRIPTION

TK-361SA

10

IC101 (2/2) compares the output voltage of IC101 (1/2) with the reference voltage from MCU (IC405). The output of IC101 (2/2) controls the VG of the RF power amplifi er, Drive amplifi er and Pre-Drive amplifi er to make both voltages the same.

The change of power high/low is carried out by the change of the reference voltage.

■ Encode Signaling

• QT/DQTQT,DQT data of the QTTCXO Line is output from pin 28

of the MCU (IC405). The signal passes through a low-pass CR fi lter and goes to the TCXO (X1).

The QT,DQT data of the QTVCO Line is output from pin 24 of the MCU. The signal passes through a low pass CR fi l-ter, mixes with the audio signal, and goes to the VCO modu-lation input. TX deviation is adjusted by the MCU.

5. Power Supply

There are four 5V power supplies 5M, 5C, 5R, and 5T. 5M for MCU (IC405) 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 MCU.

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 MCU (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 in-

put.(6) Transmitting tone and encode data.

■ Frequency Shift CircuitThe MCU (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 inter-nal spurious transmission modulated sound of a transceiver.

■ Low Battery WarningThe battery voltage is checked by the MCU (IC405).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 recep-

tion 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. Dur-ing 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.

ADJUSTMENT

The following parts are required for adjustment

1. Antenna connector adapterThe antenna connector of this radio uses an SMA termi-

nal.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.)

2. Repair Jig (Chassis)Use jig (part No.: A10-4086-03) for repairing the TK-

361SA. Place the TX-RX unit on the jig and fi t it with screws.The jig facilitates the voltage check and protects the fi nal

amplifi er FET when the voltage on the fl ow side of the TX-RX unit is checked during repairs.

3. Battery Jig (W05-1011-00)

+ Terminal (Red)

– Terminal (Black)

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, be-tween the power supply and the battery jig, especially while the transceiver transmits.

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 con-nected to a suitable dummy load (i.e. power meter).

The speaker output connector must be terminated with a 8Ω dummy load and connected to an AC voltmeter and an audio distortion meter or a SINAD measurement meter at all times during tuning.
