CIRCUIT DESCRIPTION
RX Section
The front end unit is comprised of a dual gate MOS FET and
helical resonator. The 2-stage MCF (Monolithic Crystal
Filter) following the 1st mixer Q2 (3SK74) provides excellent
2-signal characteristic and high sensitivity.
The IF signal from the MCF is divided and applied to the SSB
and FM circuits. The SSB signal passes through the NB
(Noise Blanker) gate crystal filter (10H2.2SD) and is
amplified by the transmit/receive IF amplifier. Q27, Q28 and
29, and is then demodulated into an audio signal by the
product detector.
In the NB circuit, the signal from the MCF passes through the
buffer amplifier Q6 and is fed to the 2nd mixer Q7. This
signal is converted 455 kHz and the noise is amplified by two
stages for switching the NB gate. The NB is front panel con-
trolled.
In the AGC circuit, the signal from the final IF stage is
detected and amplified, and the time constant is automatical-
ly select according to the mode of operation, FAST in CW
mode and SLOW in SSB mode. The AGC signal is applied to
the 3-stage IF amplifier, Q27, 28 and 29 (3SK74), and the
RF amplifier Q1. The AGC voltage is also used for meter
indication.
In the FM circuit. the signal from the ceramic filter CFW-
455E is amplified by the IF amplifier Q13 (TA7302P). The
auto scan stop signal is applied to the micro-computer from
the squelch circult.
The detected AF signal is amplified by the AF amplifier Q18,
a 2SC1815(Y). The amplified signal passes through the LPF
(Low Pass Filter) Q19. a 2SC1815(Y) and is power-amplified
by Q26, (HA1366W) via the AF GAIN control to drive the
speaker.

applied to the mixer through the oscillator circuit Q3 (10,695
MHz) and buffer amplifier Q4 a 2SC460 (B). The remaining
circuits are common to all the operating modes. The 4-stage
BPF (Band Pass Filter) next to the mixer ts used to eliminate
unwanted spurious signals. After filtering, the signal is
amplified by Q7, a 3SK74 (L) to drive the final unit via Q8
(2SC2538).
In the ALC circuit, the drive output from O8 is amplified by
Q9, a 2SC2603 (E) and is applied to the 2nd gates of the
predriver Q7 and IF amplifier Q27.
The HI/LOW selection and protection in the FM and CW
modes is accomplished by changing the source voltage of
Q7, the predriver. In CW mode, the keying circuit controls

CIRCUIT DESCRIPTION
PLL Unit (X50-1620-11)
Fig. 2 shows a basic block diagram of PLL circuit. The signal
from the VCO (Q1, a 2SK19 (GR)) passes through the buffer
amplifier formed by Q2, a 2SC1923 (O) and O5, a 3SK74
(L), and is then mixed with the HET (Heterodyne) signal by
Q13, a 2SC1923 (O) to produce 5.5 ~ 7.49 MHz signal.
This signal is amplified by Q10, 11 and Q12, 2SC460 (B)
and is frequency-divided by Q18 (TC9122P) according to the
BCD data (MHz, 100 kHz and 10 kHz order) from the control
unit, to produce 10 kHz comparison signa!. Simultaneously,
the 10.24 MHz signal from the RX unit is frequency-divided
to 1/1024 by Q17 (TC5O082P-GL) to produce 10 kHz
reference signal. These signals are phase-compared by Q16
(TC5081P) and fed to the LPF formed by Q8 and QQ, and the
resulting control voltage is applied to the VCO vari-cap tuning
diode.
The 14.2 MHz VCO HET signal is generated by crystal oscil-
lator 06, a 2SC460 (B), and is then multiplied 9 times by D4
(1$S16) to produce a 127.8 MHz signal. This signal is then
applied to the mixer, Q13, a 2$C1923 (O).
The crystal oscillator circuit has two vari-cap diodes to con-
trol frequency. A DC signal. corresponding to 0 ~ 9.9 kHz
produced by the control unit (X53-1160-00),. is voltage con-
verted by Q7, a 2SK30A (GR) and is fed to the vari-cap D6
(1$2208) to control the frequency. The other vari-cap D5
(1SV50S) is used to shift the frequency (fuse = frm + 1.5
kHz. fiss = fem — 1.5 kHz) according to the operating mode
and to afford RIT (Receive Incremental Tuning) frequency.

CONTROL Unit (X53-1160-11)
Fig. 8 shows the basic configuration of contro! unit. Utilizing
the micro-computer to it’s full advantage, this control circuit
has been designed for a minimum of peripheral control cir-
cuits.
@ Indicator
The indicator is a dynamic lighting (scanning) type, using
5-digit LED's. The BCD code data available at the
micro-computer D port (pins 8-11) is converted into
7-segment data by the decoder driver Q18 (TC5)22BP),
so that transistors Q5-9, 25C1815 (Y) are switched
(scanned) in sequence by the digit signa! from theE and F
ports (pins 12-16) and light the LEDs.
e@ PLL Data Output
The PLL MHz, 100 kHz and 10 kHz order data outputs are
available directly from the BCD code at the G,H and |
ports (pins 22-32). For the 1 kHz and 100 Hz order data,
only the indicator data (1 kHz and 100 Hz orler) are
stored in the dual latch, Q16 (MN1201A) to produce the.
data for each digit.
This 2-digit data is converted to a corresponding DC
voltage by the D/A converter, a combination of solid
resistors (R6-20).
The MHz, 100 kHz and 10 kHz order data are&50 at
4.00, 650 at 5.00 and 749 at 5.99, respectively( 3-digit
BCD code).
@ Reset Circuit
