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 : 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.
1. Frequency Configuration
The receiver utilizes double conversion. The first IF is
49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary
frequencies. Figure 1 shows the frequencies.

D701 and D702 are switched to ceramic filters when a
Wide/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.

and D608), passes through a BPF (L715 and L716), and is
amplified 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 variable
capacitors (D703, D704, D705 and D706). The input voltage

The 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 through
the harmonic filter (LPF) and antenna switch (D604 and D605)
and applied to the antenna terminal.

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 signal 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 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.

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.

5-1. Frequency Shift Circuit
C62
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
185.95~223.95MHz and the 136~174MHz. The VCO generates 185.95~223.95MHz 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 (D504, D505, D506 and D507 in transmit
mode and D508, D509, D510 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.
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.

5-3. Low Battery Warning
The battery voltage is monitored by the microprocessor
(IC7 pin 123 : BATTLVL). When the battery voltage falls below the voltage set by the Low Battery Warning adjustment
during the transmission, the red LED blinks to notify the operator that it is time to replace the battery (When the “On
TX” option (default setting) under the Battery Warning / status function in the FPU is selected.). If the battery voltage
falls below 5.9V, the transceiver does not transmit and the
warning tone beeps while the PTT switch is pressed.

TX HSD tone and a RX HSD tone. TX HSD deviation making
an adjustment by microprocessor is passed through the
switch (IC14) and then applied to the audio processor (IC13).
The signal is mixed with the audio signal and goes to the
VCO and TCXO. The RX HSD tone is passed a summing amplifier (IC18). The D/A converter (IC16) for audio control, audio power amplifier and then to the speaker.

■ QT/DQT
The output signal from IF IC (IC701) enters the microprocessor (IC7) through IC11. IC7 determines whether the QT
or DQT matches the preset value, and controls the AM1 using IC5 and the speaker output sounds according to the
squelch results.
■ 2-tone
Part 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 then
goes to IC7. IC7 checks whether 2-tone data is necessary. If
it matches, IC7 carries out a specified operation, such as turning the speaker on. (See Figure 4)
7. Power Supply
There are five 5V power supplies for the microprocessor:
5M, 5MS, 5C, 5R and 5T.
5M 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 microprocessor.
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.
■ MSK (Fleet Sync)
Fleet Sync utilizes 1200bps and 2400bps MSK signal is
output from pin 6 of IC13. And is routed to the VCO. When
encoding MSK, the microphone input signal is muted.
■ DTMF
The DTMF input signal from the IF IC (IC701) is amplified
by IC10 and goes to IC13. The decoded information is then
processed by the CPU.

Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be connected 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.

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, between the
power supply and the battery jig, especially while the transceiver transmits.

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.
When using the battery jig in user mode, the transceiver
assumes that a lithium-ion battery pack is attached to the
transceiver. In adjustment mode, battery type detection is
not performed. Refer to page 26 for details.
