4-3. Operation1. To switch the clone target/s to wireless 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.

4. To switch the clone source to wireless 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 target/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” 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 wireless clone mode is confi gured as

“Disabled”, the transceiver cannot enter wireless clone mode.

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

• Wireless 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.

• The language used in cloning depends on the “Model type” setting, not the FPU setting.

• 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.

• Electronic interface may cause a failure in data transfer during wireless clone, such as when waveforms or elec-tromagnetics are being performed at the workbench.

• Wireless clone mode can be used ONLY by the autho-

rized service personnel.

• The wireless clone mode setting must be confi gured

as “Disable” before being delivered to the end-user.

• To clone, replace the antenna from both the source

transceiver and the target transceiver with a dummy

load.

• The transmit output power is automatically set to

Low in wireless clone mode.

• Clone frequency table

■ Front End (RF AMP)The signal coming from the antenna passes through the

transmit/receive switching diode circuit, (D103, D104 and D105) passes through a BPF (L213 and L212), and is ampli-

CIRCUIT DESCRIPTION

fi ed by the RF amplifi er (Q204).The resulting signal passes through a BPF (L209, L207

and L206) and goes to the mixer. These BPFs are adjusted by variable capacitors (D201, D202, D203, D204 and D205). The input voltage to the variable capacitor is regulated by voltage output from the MCU (IC306).

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

oscillator signal generated in the PLL circuit by Q203 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 monolithic

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-fier (Q202) and then applied to the lF system IC (IC201). The IF system IC provides a second mixer, limiting amplifi er, quadrature detector and RSSI (Received Signal Strength In-dicator). The second mixer mixes the fi rst IF signal with the 38.4MHz of the second local oscillator output (TCXO X1 and Q2) 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.

■ Wide/Narrow Switching CircuitNarrow 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 IC306, pin 5. When a WIDE (low level) data is received, Q201 turn on. When a NARROW (high level) data is received, Q201 turn off.

Q201 turns on/off with the Wide/Narrow data and the IC201 detector output level is switched to maintain a con-stant output level during wide or narrow signals.

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

through IC308.The signal then goes through an AF volume control , and

is routed to an audio power amplifi er (IC309) 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 (IC306). IC306 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, IC306 sends a high signal to the AF_CONT line and turns IC309 on through Q312, Q313, Q314, Q315 and Q316. (See Fig. 4)

■ Receive Signaling

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

(IC306) through IC308. IC306 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.

• MSK (Fleet Sync)The MSK input signal from the FM IC goes to pin 31 of IC

308. The signal is demodulated by MSK demodulator in IC 308. The demodulated data goes to the MCU for process-ing.

• DTMFThe DTMF input signal from the FM IC (IC201) goes to

IC308. The decoded information is then processed by the MCU.

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 oscillator signal is divided at IC1 by

a fi xed counter to produce an oscillator (VCO) output signal which is buffer amplifi ed by Q3 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. 5)

■ VCOThe operating frequency is generated by Q5 in transmit

mode and Q4 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 D8 in transmit mode and D3 and D6 in receive mode).

The RX_SW pin is set high in receive mode causing Q7 turn on. The TX_SW pin is set high in transmit mode. The outputs from Q4 and Q5 are amplifi ed by Q9 and sent to the RF amplifi ers.

■ Unlock DetectorIf a pulse signal appears at the LD pin of IC1, an unlock

condition occurs, and the DC voltage obtained from C4 and Q1 causes the voltage applied to the MCU to go low. When the MCU detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal.

4. Transmitter System

■ Microphone Amplifi erThe signal from the microphone passes through the

IC308. When encoding DTMF, it is turned OFF for muting the microphone input signal by IC308.

The signal passes through the Audio processor (IC308) for the maximum deviation adjustment, and goes to the VCO modulation input.

■ Drive and Final Amplifi erThe signal from the T/R switch (D10 is on) is amplifi ed by

the pre-drive (Q101 and Q102) and the drive amplifi er (Q103) to 500mW.

The output of the drive amplifi er is amplifi ed by the RF power amplifier (Q106) to 4.0W (1W when the power is low). The output of the RF power amplifi er is then passed through the harmonic fi lter (LPF) and antenna switch (D103) and applied to the antenna terminal.

■ APC CircuitThe APC circuit always monitors the current flowing

through the drive amplifi er and RF power amplifi er (Q103 and Q106) and keeps a constant current.

The voltage drop at R120, R123 and R126 is caused by the current flowing through the RF power amplifier and drive amplifi er, and this voltage is applied to the differential amplifi er IC101 (1/2).

CIRCUIT DESCRIPTION

IC101 (2/2) compares the output voltage of IC101 (1/2) with the reference voltage from IC306. The output of IC101 (2/2) controls the VG of the RF power amplifier and 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 14

of the MCU. 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 15 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.

• DTMFHigh-speed data is output from pin 74 of the MCU. The

signal passes through a low-pass CR fi lter, and provides a TX and SP out tone, and is then applied to the audio proces-sor (IC308). The signal is mixed with the audio signal and goes to the VCO.

TX deviation is adjusted by the MCU.

• MSK (Fleet Sync)Fleet Sync utilizes 1200bps and 2400bps MSK signal is

output from pin 6 of IC308. And is routed to the VCO. When encoding MSK, the microphone input signal is muted.

5. Power Supply

There are four 5V power supplies in the transceiver: 5M, 5C, 5R, and 5T. 5M for MCU 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 (IC306) and its peripheral circuits. It controls the TX-RX unit. IC306 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 (IC306) operates at a clock of 14.746 MHz. This

oscillator has a circuit that shifts the frequency by BEAT SHIFT SW (Q305, Q306).

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.

■ Memory CircuitMemory circuit consists of the MCU (IC306) and an EE-

PROM (IC305). An EEPROM has a capacity of 16k bits that contains the transceiver control program for the MCU and data such as transceiver channels and operating features.

■ Low Battery WarningThe battery voltage is checked using by the MCU. 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. 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.

■ Antenna connector adapterThe antenna connector of this transceiver 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.)

■ Repair Jig (Chassis)Use jig (part No.: A10-4215-03) for repairing the transceiv-

er. 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.

■ Battery Jig (W05-1011-00)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.
