5-2. Connection Procedure

1. Connect the transceiver to the personal computer with the interface cable.

2. When the POWER switch on, user mode can be entered immediately. When PC sends command the transceiver enter PC mode, and “PROGRAM” is displayed on the LCD. When data transmitting from transceiver, the red LED is lights. When data receiving to transceiver, the green LED is lights.

Note:

• The data stored in the personal computer must match model type, when it is written into the flash memory.

5-3. KPG-22 Description (PC programming interface cable: Option)

The KPG-22 is required to interface the transceiver to the

computer. It has a circuit in its D-subconnector (25-pin) case that converts the RS-232C logic level to the TTL level.

The KPG-22 connects the SP/MIC connector of the trans-

ceiver to the computers RS-232C serial port.

5-4. Programming Software KPG-101D Description

The KPG-101D is the programming software for the trans-

ceiver supplied on a CD-ROM. This software runs under MSWindows 98, ME, Windows 2000 or XP on an IBM-PC or compatible machine.

The data can be input to or read from the transceiver and

edited on the screen. The programmed or edited data can be printed out. It is also possible to tune the transceiver.

6. Firmware Programming Mode

6-1. Preface

Flash memory is mounted on the transceiver. This allows

the transceiver to be upgraded when new features are released in the future. (For details on how to obtain the firmware, contact Customer Service.)

6-2. Connection Procedure

Connect the transceiver to the personal computer (IBM

PC or compatible) with the interface cable (KPG-22). (Connection is the same as in the PC Mode.)

6-3. Programming

1. Start up the firmware programming software (Fpro.exe).

2. Set the communications speed (normally, 115200 bps) and communications port in the configuration item.

3. Set the firmware to be updated by File name item.

4. Turn the transceiver power ON with the [Side2] key held down. Then, the orange LED on the transceiver lights and “PROG 1152” is displayed.

5. Check the connection between the transceiver and the personal computer, and make sure that the transceiver is in the Program mode.

6. Press write button in the window. When the transceiver starts to receive data, the “LOADING” is displayed.

7. If writing ends successfully, the checksum is calculated and a result is displayed.

8. If you want to continue programming other transceivers, repeat steps 4 to 7.

Notes:

• This mode cannot be entered if the Firmware Programming mode is set to Disable in the Programming software.

• When programming the firmware, it is recommend to copy the data from the floppy disk to your hard disk before update the radio firmware. Directly copying from the floppy disk to the radio may not work because the access speed is too slow.

6-4. Function

1. If you press the [Side2] key while “PROG 1152” is displayed, the display changes to “PROG 192” to indicate that the write speed is low speed (19200 bps). If you press the [Side2] key again while “PROG 192” is displayed, the display changes to “PROG 384”. If you press the [Side2] key again while “PROG 384” is displayed, the display changes to “PROG 576”. If you press the [Side2] key again while “PROG 576” is displayed, the display returns to “PROG 1152”.

2. If you press the [Side1] key while “PROG 1152” is displayed, the checksum is calculated, and a result is displayed. If you press the [Side1] key again while the checksum is displayed, “PROG 1152” is redisplayed.

Note:

Normally, write in the high-speed mode.

7. Clone Mode

Programming data can be transferred from one trans-

ceiver to another by connecting them via their SP/MIC connectors. The operation is as follows (the transmit transceiver is the master and the receive transceiver is a slave).

The following data cannot be cloned.

• Tuning data

• Embedded message with password

• Serial number

The “password” of description by explanation of 1. to 7.

are “Read Authorization Password”.

1. Turn the master transceiver power ON with the [B] key held down. If the Data password is set to the transceiver, the transceiver displays “CLN LOCK”. If the password is not set, the transceiver displays “CLONE”.

2. When you enter the correct password, and “CLONE” is displayed, the transceiver can be used as the cloning master. The following describes how to enter the password.

3. How to enter the password with the keypad; If you press a key while “CLN LOCK” is displayed, the number that was pressed is displayed on the transceiver. Each press of the key shifts the display in order to the left. When you enter the password and press the [ “CLONE” is displayed if the entered password is correct. If the password is incorrect, “CLN LOCK” is redisplayed.

2. Receiver System

The receiver system is shown in Figure 2.

The filtered first IF signal is amplified by the first IF amplifier (Q703) and then applied to the lF system IC (IC701). 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 50.4MHz of the second local oscillator output (TCXO X501) and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic filter (Wide 5k, Wide 4k : CF701, Narrow : CF702) 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 (CD701). The demodulated signal is routed to the audio circuit.

2-4. Wide 5k, Wide 4k/Narrow Switching Circuit

Wide 5k, Wide 4k and Narrow settings can be made for each channel by switching the ceramic filters CF701 (Wide 5k, Wide 4k), CF702 (Narrow). The Wide 5k, Wide 4k and Narrow switching data is output from IC4.

D701 and D702 are switched to ceramic filters when a Wide 5k, Wide 4k/Narrow level is selected.

Q702 turns on/off with the Narrow and the IC701 detector output level is changed to maintain a constant output level during wide or narrow signals.

2-1. Front End (RF AMP)

The signal coming from the antenna passes through the transmit/receive switching diode circuit (D604, D605, D606 and D608), passes through a BPF (L717 and L718), and is amplified by the RF amplifier (Q705).

The resulting signal passes through a BPF (L711, L712 and L713) and goes to the mixer. These BPFs are adjusted by variable capacitors (D703, D704, D705, D706 and D707). The input voltage to the variable capacitor is regulated by voltage output from the DC amplifier (IC19).

2-2. First Mixer

The signal from the front end is mixed with the first local oscillator signal generated in the PLL circuit by Q704 to produce a first IF frequency of 49.95 MHz.

The resulting signal passes through the XF701 MCF to cut the adjacent spurious and provide the optimum characteristics, such as adjacent frequency selectivity.

2-3. IF Amplifier Circuit

The first IF signal is passed through a four-pole monolithic crystal filter (XF701) to remove the adjacent channel signal.

CIRCUIT DESCRIPTION

2-5. Audio Amplifier Circuit

The demodulated signal from IC701 is amplified by IC10,

and goes to AF amplifier through IC13.

The signal then goes through an volume control (IC16),

and is routed to an audio power amplifier (IC18) where it is amplified and output to the speaker.

2-6. Squelch Circuit

Part of the AF signal from the IC enters the FM IC (IC701)

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 (IC7). IC7 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, IC7 sends a high sig-

nal to the AM2 line and IC5 sends a high signal to the AM1 line, and turns IC18 on through Q23, Q24, Q27, Q28 and Q35. (See Figure 4)

The signal enters the summing amplifier consisting of

IC12 (2/2), and passes through the D/A converter (IC16) for the maximum deviation adjustment, and is mixed with the low speed data from the CPU (IC7).

The output signal from the D/A converter goes to the VCO

modulation input. The other output signal from the D/A converter passes through the D/A converter (IC16) again for the BAL adjustment, and the buffer amplifier (IC17), and goes to the TCXO modulation input.

3-2. Drive and Final Amplifier

The signal from the T/R switch (D516 is on) is amplified by

the pre-drive (Q602) and drive amplifier (Q603) to 50mW.

The output of the drive amplifier is amplified by the RF final amplifier (Q604) to 4.0W (1W when the power is low). The RF final amplifier consists of two MOS FET stages.

The output of the RF final amplifier is then passed through the harmonic filter (LPF) and antenna switch (D604 and D605) and applied to the antenna terminal.

3-3. APC Circuit

The APC circuit always monitors the current flowing through the RF power amplifier (Q604) and keeps a constant current. The voltage drop at R621, R623 and R629 is caused by the current flowing through the RF final amplifier and this voltage is applied to the differential amplifier IC601(1/2).

IC601(2/2) compares the output voltage of IC601(1/2) with the reference voltage from IC7. The output of IC601(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.

4. Frequency Synthesizer Unit

4-1. Frequency Synthesizer

The frequency synthesizer consists of the TCXO (X501),

VCO, PLL IC (IC501) and buffer amplifiers.

The TCXO generates 16.8MHz. The frequency stability is

2.5ppm within the temperature range of –30 to +60°C. The frequency tuning and modulation of the TCXO are done to apply a voltage to pin 1 of the TCXO. The output of the TCXO is applied to pin 8 of the PLL IC.

The VCO consists of 2VCO and covers a dual range of the

390.05~420.05MHz (E) or 420.05~462.05MHz (X2) and the 440~470MHz (E) or 470~512MHz (X2). The VCO generates

390.05~420.05MHz (E) or 420.05~462.05MHz (X2) for providing to the first local signal in receive. The operating frequency is generated by Q502 in transmit mode and Q503 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator (IC501) to the variable capacitor diodes (D505 and D507 in transmit mode and D509 and D511 in receive mode).

The RX pin of IC4 goes “low” in receive mode causing Q503 and Q504 (2/2) turn on. The TX pin goes “low” in transmit mode causing Q502 and Q504 (1/2) turn on.

The outputs from Q502 and Q503 are amplified by buffer amplifier (Q506) and doubled by Q501 and then sent to PLL IC.

The PLL IC consists of a prescaler, reference divider, phase comparator, charge pump (The frequency step of the PLL circuit is 5 or 6.25kHz). The input signal from the pins 8 and 5 of the PLL IC is divided down to the 5 or 6.25kHz and compared at phase comparator. The pulsed output signal of the phase comparator is applied to the charge pump and transformed into DC signal in the loop filter (LPF). The DC signal is applied to the CV of the VCO and locked to keep the VCO frequency constant.

PLL data is output from PLLDAT (pin 93), PCK (pin 79) and PLE (pin 78) of the microprocessor (IC7). The data are input to the PLL IC when the channel is changed or when transmission is changed to reception and vice versa. A PLL lock condition is always monitored by the pin 77 (UL) of the microprocessor. When the PLL is unlocked, the UL goes low.

5. Control Circuit

The control circuit consists of microprocessor (IC7) and its peripheral circuits. It controls the TX-RX unit. IC7 mainly performs the following;

1) Switching between transmission and reception by PTT

signal input.

2) Reading system, zone, 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 decode data input.

6) Transmitting tone and encode data.

5-1. Frequency Shift Circuit

The microprocessor (IC7) operates at a clock of 11.0592 MHz. This oscillator has a circuit that shifts the frequency by Beat shift switch (Q17).

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.

5-2. Memory Circuit

Memory circuit consists of the CPU (IC7) and a flash memory (IC8). A flash memory has a capacity of 4M bits and contains the transceiver control program for the CPU. It also stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily written from an external devices.

The EEPROM (IC9) stores the last channel data, the scan on status, and other parameters.

■ Flash memory

Note : The flash memory stores the data that is written by

the FPU (KPG-101D), and firmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the flash memory.

■ EEPROM

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

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