4. Wireless Clone Mode

4-1. Outline“Wireless 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.

4-2. 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 wireless

clone mode.

4-3. Operation1. To switch the clone target/s to Clone mode, press and

hold the [<B] key while turning the transceiver power ON.

2. Wait for 2 seconds. “CLONE” appears on the LCD, fol-lowed by “FRQTBL 1”.

3. Select a channel table number using the [Selector] knob.4. To switch the clone source to Clone mode, press and

hold the [<B] key while turning the transceiver power ON.

5. Wait for 2 seconds. “CLONE” appears on the LCD, fol-lowed by “FRQTBL 1”.

6. Select the same channel table number as the clone tar-get/s.

7. Press the [S] key on the clone master to begin data trans-mission. When the clone target starts to receive data, the green LED will light and “CLONING” will appear on the LCD. The source unit will display “MASTER”.

8. When the clone source fi nishes sending data, a “confi r-mation” tone will sound and “COMPLETE” will appear on the LCD. If data transmission failed while cloning, the target unit will produced an error tone and “CLONE NG” will appear on the LCD.

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

10. When the cloning is successful, the target unit's “Scan” and “Key lock” functions will return to their default val-ues (Scan = OFF, Key lock = OFF).

11. The source will remain in clone mode after cloning. The target unit will return to user mode after a successful cloning.

Note:• 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 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 the [S] key 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.

• MSK signaling is used in cloning.

• 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 wireless 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 Clone mode.

2-1. Front End (RF Amplifi er) CircuitThe signal coming from the antenna passes through the

transmit / receive switching diode circuit (D201, D202, D203 and D204) and a BPF (L418 and L419), and is then amplifi ed by the RF amplifi er (Q407).

The resulting signal passes through a BPF (L419, L418, L416 and L414) and goes to the mixer. These BPFs are ad-justed by variable capacitance diodes (D408, D407, D405 and D404). The input voltage to the variable capacitance diodes is a regulated voltage output from the DC amplifi er (IC811).

2-2. First MixerThe signal from the front end is mixed with the fi rst local

oscillator signal generated in the PLL circuit by Q406 to pro-duce a fi rst IF frequency of 49.95MHz.

The resulting signal passes through the XF401 MCF to cut the adjacent spurious and provide the optimum charac-teristics, such as adjacent frequency selectivity.

13

2-3. IF Amplifi er CircuitThe fi rst IF signal is passed through a four-pole mono-

lithic crystal fi lter (XF401) to remove the adjacent channel signal. The fi ltered fi rst IF signal is amplifi ed by the fi rst IF amplifier (Q405) and is then applied to the IF system IC (IC401).

The IF system IC provides a second mixer, limiting ampli-fi er, quadrature detector and RSSI (Received Signal Strength Indicator). The second mixer mixes the fi rst IF signal with the 50.4MHz signal of the second local oscillator output (Q403) and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic fi lter (Wide: CF402, Narrow: CF401) to remove the adjacent chan-nel signal. The fi ltered second IF signal is amplifi ed by the limiting amplifi er and demodulated by the quadrature detec-tor with the ceramic discriminator (CD401). The demodu-lated signal is routed to the audio circuit.

2-4. Wide/Narrow Switching CircuitWide and narrow settings can be made for each channel

by switching the ceramic fi lters CF401 (narrow). The second IF signal always passes the ceramic fi lters

CF402 (Wide).The wide and narrow switching data is output from the

MCU (IC820).D401 and D402 are switched to ceramic fi lters when a

narrow mode is selected.Q404 turns on/off with the Narrow and the IC401 detec-

tor output level is changed to maintain a constant output level during wide or narrow signals.

2-5. Audio Amplifi er CircuitThe demodulated signal from IC401 is sent to an AF am-

plifi er through baseband IC (IC812), and is routed to an au-dio power amplifi er (IC815) where it is amplifi ed and output to the speaker.

2-6. Squelch CircuitPart of the AF signal from the IC401 enters the FM sys-

tem IC (IC401) again, and the noise component is amplifi ed 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 MCU (IC820). IC820 determines whether or not to out-put sounds from the speaker by checking if the input volt-age is higher or lower than the preset value.

To output sounds from the speaker, IC820 sends a high signal to the AF_CONT line and turns IC815 on through Q813, Q814, Q818 and Q819.

3. Transmitter System

3-1. Microphone Amplifi er CircuitThe signal from the microphone is limited by the AGC

circuit, which is composed of D807, D808, Q810, Q811 and the mute switch (Q809). IC812 is composed of a high-pass fi lter, low-pass fi lter and pre-emphasis/IDC circuit.

The signal from the microphone and the low speed data from the MCU (IC820) enter the baseband IC (IC812) and pass through each path and are mixed inside the IC.

The output signal from the baseband IC goes to the VCO modulation input. The other output signal passes through the amplifi er (IC3) and goes to the TCXO modulation input.

3-2. Driver and Final Amplifi er CircuitThe signal from the T/R switch (D18 is on) is amplifi ed by

the RF AMP (Q201) and pre-drive amplifi er (Q203) to 50mW.The output of the pre-drive amplifi er is amplifi ed by the

drive amplifi er (Q204) and the RF fi nal amplifi er (Q205) to 5.0W (1W when the power is low).

The drive amplifi er and the RF fi nal amplifi er consist of two MOS FET stages.

The output of the RF final amplifier is then passed through the harmonic fi lter (LPF) and antenna switch (D201 and D202) and is applied to the antenna terminal.

3-3. APC CircuitThe APC circuit always monitors the current flowing

through the drive amplifi er (Q204) and the RF power ampli-fi er (Q205) and keeps a constant current. The voltage drop at R307, R309 and R310 is caused by the current fl owing through the RF fi nal amplifi er. This voltage is applied to the differential amplifi er IC301 (1/2).

IC301 (2/2) compares the output voltage of IC301 (1/2) with the reference voltage from IC811. The output of IC301 (2/2) controls the VG of the RF power amplifi er and the 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.

4. Frequency Synthesizer Unit

4-1. Frequency synthesizerThe frequency synthesizer consists of the TCXO (X1),

VCO, PLL-IC (IC1), and buffer amplifi ers.The TCXO generates 16.8MHz. The frequency stability

is 1.5ppm within the temperature range of –30°C to +60°C. The frequency tuning and modulation of the TCXO are done to apply voltage to pin 1 of the TCXO. The output of the TCXO is applied to pin 10 of PLL-IC.

The operating frequency is generated by Q5 in

transmitting mode and Q4 in receiving mode. The oscillation frequency is controlled by applying the VCO control voltage, obtained from the phase comparator (IC1) to the variable ca-pacitance diodes (D4, D6, D8 and D9 in transmitting mode and D10 and D12 in receiving mode)

The TX pin of IC820 goes “high” in transmitting mode, causing Q7 and Q4 to turn off, and Q5 turn on. The TX pin goes “low” in receiving mode.

The output from Q4 and Q5 are amplifi ed by a buffer am-plifi er (Q8) and Q2, and then sent to the PLL-IC.

The PLL-IC consists of a prescaler, reference divider, phase comparator, and charge pump. The input signal from pin 10 and 17 of the PLL-IC is divided down and compared at the phase comparator. The pulsed output signal of the phase comparator is applied to the charge pump and trans-formed into a DC signal in the loop fi lter (LPF). The DC sig-nal is applied to the CV of the VCO and locked to keep the VCO frequency constant.

PLL data is output from PL_STB (pin 20), PL_CLK (pin 8), and PL_DAT (pin 21) of the MCU (IC820). The data is input to the PLL-IC when the channel is changed or transmission is changed to reception and vice versa. PLL lock condition is always monitored by pin 18 (PL_UL) of the MCU. When the PLL is unlocked, PL_UL goes low.

5. Control Circuit

The control consists of the MCU (IC820) and its peripher-al circuits. It controls the TX-RX unit. IC820 mainly performs the following;1) Switching between transmission and reception by PTT

signal input.2) Reading channel information, frequency, and program

data from the memory circuit.3) Sending frequency program data to the PLL.4) Controlling squelch on/off via the DC voltage from the

squelch circuit.5) Controlling the audio mute circuit via the decode data in-

put.6) Transmitting tone and encode data.

5-1. Frequency Shift CircuitThe MCU (IC820) and baseband IC (IC812) operates at

a clock frequency of 19.2MHz. The oscillator circuit has the baseband IC. This oscillator has a circuit that shifts the fre-quency via Beat shift switch (Q806).

A beat sound may be able to be evaded form generation if “Beat Shift“ is set to ON when it is generated in the in-ternal spurious transmission modulated sound of the trans-ceiver.

5-2. Memory CircuitThe Memory circuit consists of the MCU (IC820) and

EEPROM (IC810). The EEPROM has a capacity of 512k bits and stores the channel information, the last channel data, the scan on status, and other parameters.

■ EEPROM

Note: The EEPROM stores tuning data (Deviation, Squelch,

etc.). Realign the transceiver after replacing the EEPROM.

5-3. Low Battery WarningThe battery voltage is monitored by the MCU (IC820 pin

63: BATT). When the battery voltage falls below the volt-age set by the Low Battery Warning adjustment, the red LED blinks, notifying the operator that it is time to replace the battery (when the always option (default setting) under the Battery Warning function in the FPU is selected). If the battery voltage falls bellow 5.9V, the transceiver does not transmit and the warning tone beeps while the PTT switch is pressed.

Low battery warning Battery status

The red LED blinks during trans-mission.

The battery voltage is low but the transceiver is still usable.

The red LED blinks and the warning tone beeps while the PTT switch is pressed.

6. Signaling Circuit

6-1. Encode

■ Low-speed data (QT, DQT)Low-speed data is output from pin 2 of the MCU. The

signal passes through the low pass CR fi lter, and goes to the baseband IC (IC812). The signal is mixed with the audio signal and goes to the VCO and TCXO (X1) modulation input after passing through the D/A converter inside the baseband IC (IC812) for BAL adjustment.

■ High-speed data (2-tone)High-speed data (HSD) is output from pin 3 of the MCU.

HSD deviation made by an adjustment in the MCU is passed through the low pass CR fi lter and then applied to the base-band (IC812).

The signal is mixed with the audio signal and goes to the VCO and TCXO.

■ MSK/DTMFThe MSK/DTMF signal is generated in the baseband IC

(IC812). The signal passes through the D/A converter (in-side the baseband IC812) and is routed to the VCO. When encoding the MSK/DTMF, the microphone input signal is muted.

6-2. Dceode

■ QT/DQTThe output signal from the IF IC (IC401) enters the MCU

(IC820) through IC812. IC820 determines whether or not the QT or DQT matches the preset value, and controls the AFSW and speaker output sounds according to the squelch results.

■ 2-tonePart of the received AF signal output from the IF IC (IC401)

passes through the baseband IC (IC812) goes to the other AF amplifi er IC820 and 816, is compared, and then goes to IC820. IC820 checks whether or not the 2-tone data is nec-essary. If it matches, IC820 carries out a specifi ed operation, such as turning the speaker on.

■ MSK (Fleet Sync)The MSK input signal from the IF IC (IC401) goes to

IC812. The decoded information is then processed by the MCU.

■ DTMFThe DTMF input signal from the IF IC (IC401) goes to

IC812. The decoded information is then processed by the MCU.

7. Power Supply

There are fi ve 5V power supplies and three 3.3V power supplies: 50M, 50V, 50C, 50R, 50T, 33M, 33MS and 33B.

50M and 33M are always output while the power is on.33MS is always output, but turns off when the power is

turned off, to prevent malfunction of the MCU.50C is a common 5V and is output when SAVE is not set

to ON.50R is 5V for reception and output during reception.50T is 5V for transmission and output during transmis-

sion.50V is 5V for the SP/MIC connector.33B is 3.3V for the baseband IC (IC812).

■ 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 trans-

ceiver. 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.
