5-2. Connection Procedure1. 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 radio enterPC mode, and “PROGRAM” is displayed on the LCD.When data transmitting from transceiver, the red LED islights.When data receiving to transceiver, the green LED islights.

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) casethat 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 DescriptionThe KPG-101D is the programming software for the trans-

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

The data can be input to or read from the transceiver andedited on the screen. The programmed or edited data can beprinted out. It is also possible to tune the transceiver.

6. Firmware Programming Mode

6-1. PrefaceFlash memory is mounted on the transceiver. This allows

the transceiver to be upgraded when new features are re-leased in the future. (For details on how to obtain the firm-ware, contact Customer Service.)

6-2. Connection ProcedureConnect the transceiver to the personal computer (IBM

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

6-3. Programming1. 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 thepersonal computer, and make sure that the transceiver isin the Program mode.

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

7. If writing ends successfully, the checksum is calculatedand 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 Program-

ming 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 beforeupdate the radio firmware.Directly copying from the floppy disk to the radio may notwork because the access speed is too slow.

6-4. Function1. If you press the [Side2] key while “PROG 1152” is dis-

played, the display changes to “PROG 192” to indicatethat the write speed is low speed (19200 bps). If youpress the [Side2] key again while “PROG 192” is dis-played, the display changes to “PROG 384”. If you pressthe [Side2] key again while “PROG 384” is displayed, thedisplay changes to “PROG 576”. If you press the [Side2]key again while “PROG 576” is displayed, the display re-turns to “PROG 1152”.

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

Note:Normally, write in the high-speed mode.

7. Clone ModeProgramming data can be transferred from one radio to

another by connecting them via their SP/MIC connectors.The operation is as follows (the transmit radio is the masterand the receive radio 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] keyheld down. If the Data password is set to the transceiver,the transceiver displays “CLN LOCK”. If the password isnot set, the transceiver displays “CLONE”.

2. When you enter the correct password, and “CLONE” isdisplayed, the transceiver can be used as the cloning mas-ter. 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, thenumber 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 [*] or [S] key,“CLONE” is displayed if the entered password is correct.If the password is incorrect, “CLN LOCK” is redisplayed.

How to enter the password with the selector;If the selector is rotated while “CLN LOCK” is displayed,numbers (0 to 9) are displayed flashing. When you pressthe [C] key, the currently selected number is determined.If you press the [S] key after entering the password in thisprocedure, “CLONE” is displayed if the entered passwordis correct. If the password is incorrect, “CLN LOCK” isredisplayed.

4. Power on the slave transceiver.5. Connect the cloning cable (part No. E30-3410-05) to the

SP/MIC connectors on the master and slave.6. Press the [S] key on the master while the master displays

“CLONE”. The data of the master is sent to the slave.While the slave is receiving the data, “PROGRAM” is dis-played. When cloning of data is completed, the masterdisplays “END”, and the slave automatically operates inthe User mode. The slave can then be operated by thesame program as the master.

7. The other slave can be continuously cloned. When the [S]key on the master is pressed while the master displays“END”, the master displays “CLONE”. Carry out the op-eration in step 4 to 6.

Notes:Cannot be cloned if the password (over write password) isprogrammed to the slave.Only the same models can be cloned together.

1. Frequency ConfigurationThe receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil-lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessaryfrequencies. Figure 1 shows the frequencies.

The filtered first IF signal is amplified by the first IF amplifier(Q703) and then applied to the lF system IC (IC701). The IFsystem IC provides a second mixer, second local oscillator,limiting amplifier, quadrature detector and RSSI (ReceivedSignal Strength Indicator). The second mixer mixes the firstIF signal with the 50.4MHz of the second local oscillator out-put (TCXO X501) and produces the second IF signal of450kHz.

The second IF signal is passed through the ceramic filter(Wide : CF701, Narrow : CF702) to remove the adjacent chan-nel signal. The filtered second IF signal is amplified by thelimiting amplifier and demodulated by the quadrature detec-tor with the ceramic discriminator (CD701). 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 filters CF701 (Wide), CF702 (Nar-row). The Wide and Narrow is output from IC4.

D701 and D702 are switched to ceramic filters when aWide/Narrow level is selected.

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

2. Receiver SystemThe receiver system is shown in Figure 2.

2-1. Front End (RF AMP)The signal coming from the antenna passes through the

transmit/receive switching diode circuit (D604, D605, D606and D608), passes through a BPF (L715 and L716), and isamplified by the RF amplifier (Q705).

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

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

oscillator signal generated in the PLL circuit by Q704 to pro-duce a first IF frequency of 49.95 MHz.

The resulting signal passes through the XF701 MCF to cutthe adjacent spurious and provide the platinum characteris-tics, such as adjacent frequency selectivity.

2-3. IF Amplifier CircuitThe first IF signal is passed through a four-pole monolithic

crystal filter (XF701) to remove the adjacent channel signal.

2-5. Audio Amplifier CircuitThe 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 isamplified and output to the speaker.

2-6. Squelch CircuitPart of the AF signal from the IC enters the FM IC (IC701)

again, and the noise component is amplified and rectified by afilter and an amplifier to produce a DC voltage correspondingto the noise level.

The DC signal from the FM IC goes to the analog port ofthe microprocessor (IC7). IC7 determines whether to outputsounds from the speaker by checking whether the input volt-age 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 AM1line, and turns IC18 on through Q23, Q24, Q27, Q28 andQ35. (See Figure 4)

3. Transmitter System

3-1. Microphone AmplifierThe signal from microphone amplified by IC13 (1/2) and

limited by AGC circuit composed of D30, D31, Q25 and Q26,and goes through mute switch (Q30). IC13 is composed ofhigh-pass filter, low-pass filter and pre-emphasis/IDC circuit.

The signal enters the summing amplifier consisting ofIC12 (2/2), and passes through the D/A converter (IC16) forthe maximum deviation adjustment, and is mixed with thelow speed data from the CPU (IC7).

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

3-2. Drive and Final AmplifierThe signal from the T/R switch (D518 is on) is amplified by

the drive amplifier (Q603) to 50mW.The output of the drive amplifier is amplified by the RF

final amplifier (Q604) to 5.0W (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 throughthe harmonic filter (LPF) and antenna switch (D604 and D605)and applied to the antenna terminal.

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

through the RF power amplifier (Q604) and keeps a constantcurrent. The voltage drop at R621, R623 and R629 is causedby the current flowing through the RF final amplifier and thisvoltage is applied to the differential amplifier IC601(1/2).

IC601(2/2) compares the output voltage of IC601(1/2) withthe reference voltage from IC7. The output of IC601(2/2)controls the VG of the RF power amplifier, drive amplifier andpre-drive amplifier to make both voltages the same.

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

4. Frequency Synthesizer Unit

4-1. Frequency SynthesizerThe 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. Thefrequency tuning and modulation of the TCXO are done toapply a voltage to pin 1 of the TCXO. The output of the TCXOis applied to pin 8 of the PLL IC.

The VCO consists of 2VCO and covers a dual range of the185.95~223.95MHz and the 136~174MHz. The VCO gener-ates 185.95~223.95MHz for providing to the first local signalin receive. The operating frequency is generated by Q502 intransmit mode and Q503 in receive mode. The oscillator fre-quency is controlled by applying the VCO control voltage, ob-tained from the phase comparator (IC501) to the variable ca-pacitor diodes (D504, D505, D506 and D507 in transmitmode and D508, D509, D510 and D511 in receive mode).

The RX pin of IC4 goes “low” in receive mode causingQ503 and Q504 (2/2) turn on. The TX pin goes “low” in trans-mit mode causing Q502 and Q504 (1/2) turn on.

The outputs from Q502 and Q503 are amplified by bufferamplifier (Q506) and doubled by Q501 and then sent to PLLIC.

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

PLL data is output from PLLDAT (pin 93), PCK (pin 79) andPLE (pin 78) of the microprocessor (IC7). The data are inputto the PLL IC when the channel is changed or when transmis-sion is changed to reception and vice versa. A PLL lock con-dition is always monitored by the pin 77 (UL) of the micropro-cessor. When the PLL is unlocked, the UL goes low.

5. Control CircuitThe control circuit consists of microprocessor (IC7) and its

peripheral circuits. It controls the TX-RX unit. IC7 mainly per-forms 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 CircuitThe microprocessor (IC7) operates at a clock of 11.0592

MHz. This oscillator has a circuit that shifts the frequency byBeat 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 internalspurious transmission modulated sound of a transceiver.

5-2. Memory CircuitMemory circuit consists of the CPU (IC7) and a flash

memory (IC8). A flash memory has a capacity of 4M bits andcontains the transceiver control program for the CPU. It alsostores the data for transceiver channels and operating param-eter that are written by the FPU. This program can be easilywritten from an external devices.

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

Flash memoryNote : The flash memory stores the data that is written bythe FPU (KPG-101D), and firmware program (User mode,Test mode, Tuning mode, etc.). This data must be rewrittenwhen replacing the flash memory.

EEPROMNote : 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 microprocessor

(IC7 pin 123 : BATTLVL). When the battery voltage falls be-low the voltage set by the Low Battery Warning adjustmentduring the transmission, the red LED blinks to notify the op-erator that it is time to replace the battery (When the “OnTX” option (default setting) under the Battery Warning / sta-tus function in the FPU is selected.). If the battery voltagefalls below 5.9V, the transceiver does not transmit and thewarning tone beeps while the PTT switch is pressed.

6-1. Encode

Low-speed data (QT, DQT)Low-speed data is output from pin 30 of the CPU. The

signal passes through MOD amplifier (IC12 1/2), and goes tothe buffer amplifier (IC17 2/2). The signal is mixed with theaudio signal and goes to the VCO and TCXO (X501) modula-tion input after passing through the D/A converter (IC16) forBAL adjustment.

High-speed data (2-tone, DTMF)High-speed data (HSD) is output from pin 4 of the CPU.

The signal passes through a low-pass CR filter and provides aTX HSD tone and a RX HSD tone. TX HSD deviation makingan adjustment by microprocessor is passed through theswitch (IC14) and then applied to the audio processor (IC13).

The signal is mixed with the audio signal and goes to theVCO and TCXO. The RX HSD tone is passed a summing am-plifier (IC18). The D/A converter (IC16) for audio control, au-dio power amplifier and then to the speaker.

MSKMSK signal is output from pin 6 of IC13. The signal passes

through the D/A converter (IC16) and is routed to the VCO.When encoding MSK, the microphone input signal is muted.

QT/DQTThe output signal from IF IC (IC701) enters the micropro-

cessor (IC7) through IC11. IC7 determines whether the QTor DQT matches the preset value, and controls the AM1 us-ing IC5 and the speaker output sounds according to thesquelch results.

2-tonePart of the received AF signal output from the AF amplifier

IC10, and then passes through an audio processor (IC13),goes to the other AF amplifier IC15, is compared, and thengoes to IC7. IC7 checks whether 2-tone data is necessary. Ifit matches, IC7 carries out a specified operation, such as turn-ing the speaker on. (See Figure 4)

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

output from pin 6 of IC13. And is routed to the VCO. Whenencoding MSK, the microphone input signal is muted.

Panel Tuning Mode

Preparations for tuning the transceiverBefore attempting to tune the transceiver, connect the

unit to a suitable power supply.Whenever the transmitter is turned, 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 anaudio distortion meter or a SINAD measurement meter at alltimes during tuning.

Transceiver tuning

(To place transceiver in tuning mode)Press [S] key, now in tuning mode. Use [B] key to write

tuning data through tuning modes, and [Selector] to adjusttuning requirements (1 to 256 appeares on LCD).

Use [C] key to select the adjustment item through tuningmodes. Use [A] key to adjust 3 or 5 reference level adjust-ments, and use [Side2] key to switch between Wide/Narrow.

Channel appears on LCD. Set channel according to tuningrequirements.

Antenna Connector AdapterThe antenna connector of this radio uses an SMA termi-

nal. Use an antenna connector adapter [SMA(f) – BNC(f) orSMA(f) – N(f)] for adjustment. (The adapter is not provided asan option, so buy a commercially-available one.)

Battery Jig (W05-0909-00)Connect the power cable properly between the battery jig

installed in the transceiver and the power supply, and be sureoutput voltage and the power supply polarity prior to switch-ing the power supply ON, otherwise over voltage and reverseconnection may damage the transceiver, or the power supplyor both.

When using the battery jig in user mode, the transceiverassumes that a lithium-ion battery pack is attached to thetransceiver. In adjustment mode, battery type detection isnot performed. Refer to page 26 for details.

Note : When using the battery jig, you must measure thevoltage at the terminals of the battery jig. Otherwise, a slightvoltage drop may occur within the power cable, between thepower supply and the battery jig, especially while the trans-ceiver transmits.
