When replacing the “B30-2322-05” or “B30-2323-05”
LED used by the Display unit (A/6), order and replace the
LED for service into which the rank is divided according to
brightness, according to the following procedures, so that
the brightness of the LED backlight remains uniform after
replacing the LED.

Precautions for Reassembly
Perform the following steps when assembling the bottom
side of the transceiver.
1. Separate the two coaxial cables (E37-1495-05, E37-1496-
05) as shown in the fi gure.
2. Push the two fl at cables (E37-1491-05, E37-1492-05) into
the gap of the chassis so they do not come into contact
with the cabinet.
2. Order and replace the LED for service as shown in the
following table according to whether stamp “A” or “Z”
exists or not.

CIRCUIT DESCRIPTION
Frequency Confi guration
Figure 1 shows the frequency confi guration of this trans-
ceiver.
While transmitting, FM mode operates in a double con-
version and other modes (AM, SSB, CW, FSK) operate in a
triple conversion.
While receiving, the fi rst IF operates in 73.095MHz triple
conversion. In modes other than FM, the third IF is 24kHz,
and the IF signal is converted by an A/D converter and input
into DSP. The FM mode is detected in the FM IC, and the
audio signal is converted by an A/D converter and input into
the DSP. Under the following conditions, the fi rst IF oper-
ates its reception in 11.374MHz double conversion.
1) Modes other than AM or FM
2) Amateur band within the 1.8/3.5/7/14/21MHz bands
3) DSP fi lter’s bandwidth is 2.7kHz or lower

Fig. 1 Frequency confi guration
Reference Signal Generator
The reference frequency (fstd), which is used to control
the individual LO frequencies, oscillates at 15.6MHz in a
crystal oscillation circuit (X502, Q501). This 15.6MHz signal
passes through a buffer (Q502) and is doubled in a multiplier
(Q503) to generate a 31.2MHz signal. The 31.2MHz signal is
used as a reference signal for LO3 (the third local oscillator)
DDS (IC601). The 31.2MHz signal is doubled in multipliers
(Q504, Q505) to generate a 62.4MHz signal. The 62.4MHz
signal is used as a reference signal for LO1 (the fi rst local
oscillator) PLL (IC801).
The SO-3 (TCXO unit: 15.6MHz) is confi gured as an op-
tion in this transceiver, so that you can replace the crystal
oscillation circuit (X502, Q501) with the SO-3. When using
the SO-3, remove the CN903 and CN904 short jumper wires
in order to stop the operation of the crystal oscillation circuit
(X502, Q501).
LO1/ LO2/ LO3

LO1 (the fi rst local oscillator)
The VCO (Q806) oscillates at 196.8MHz. Only the double
frequency component, 393.6MHz, of this VCO’s oscilla-
tion output is extracted and input into PLL (IC801) pin 6.
This input signal is divided into 1/N within the PLL. Also,
the 62.4MHz signal (15.6MHz reference frequency x 4) is
input into PLL pin 8 and divided into 1/R within the PLL. By
a phase comparator in the PLL, the frequency divided into
1/N and the frequency divided into 1/R are compared, and
then the frequency is locked. The comparison frequency (fø)
at this time is 120kHz when transmitting FM, and 2.4MHz
otherwise.
393.6MHz signal locked by PLL (IC801) would be used
as reference by DDS (IC803). The output signal from DDS
(IC803) is 12.495MHz to 32.195MHz when RX-1 path is
selected, amplified at the broad band amplifier (IC804),
