A LIG N M E N T INSTRUCTIONS
1.
RECEIVER
1) Set the Mode Switch to AM, Volume Control at maximu, Squelch at minimum and Clarifier in
the center.
2) Set the SSG on Channel 40 and Channel Selector o f the unit on Channel 40.
Then, connect the Power Supply and 8 ohms Dummy Load to the transceiver unit.
3) Feed the signal from the SSG and set the audio output for a peak reading by adjusting T-1, T-2,
T-3, and T-4.
In this case be sure that antenna input shouid be less than 1 pV at the AF standard output power.
Also, make sure that the audio on the oscilloscope is a sine wave.
4) Set the antenna input at 1pV so that the antenna power may be more than 0.5 w att at the
maximum volume o f all channels.
5} Set the antenna input at 1,000pV so that the output power shouid be more than 3.0 watts at
the maximum volume.
6) Set the antenna input to 50,000
m
V and the low frequency output to 0.5 w att by volume con
tro!. Then, decrease the antenna input until the low frequency output stays 10 dB lower. Be
sure that the antenna input then shouid be less than 5pV.
7) Set the antenna input to 100
m
V and the meter indication to 9 by VR-2.
8) Set the volume control and squelch control at maximum, and set the tight squelch by VR3 so
that the output from speaker is heard when the antenna input is increased upto 1,000д V.
9) Set the antenna input to 0.7pV and be sure that the low frequency output shouid be over 10 dB
more when the modulation o f the SSG is turned o ff at the normal output.
10} Set the Mode Switch to USB, Volume Control at maximum, Squelch at minimum and Clarifier
in the center. Tune o ff the modulation o f the SSG and remove the frequency by 1 KHz.
11) Make sure that the maximum sensitivity shouid be less than 1pV.
12) Make sure o f AGC like with AM.
13) Set the antenna input to 0.2pV and keep the AF output to be over 10 dB lower when the
antenna input is turned o ff at the normal output.

TRANSMITTER
1) Connection o f test equipment.
* Power supply at 13.8 VDC.
* Connect a Power meter, oscilloscope frequency counter, spectrum analyzer and P-P RF volt
meter to the R F output connector.
* Connect an AF oscillator and AF volt meter to the microphone connector.
2) Power adjustment.
* Set the mode switch to AM.
* Adjust T-5, 8, 9, L-12, and L-3 for the maximum point.
* Adjust L-4 fo r 3.6W output,
* Adjust L-2 to increase 2nd harmonie.
3) Frequency-Make sure every channel stays within ±800Hz.
4) Modulation Lim iter Adjustment.
* Put in 1KHz and 20mV signal from AF oscillator and adjust VR7 for9Q% modulation
5) Modulation capability.
* Put in 1kHz signal by AF oscillator and get 90% modulation for the minus side. The plus side
shouid be over 80%.
6) SSB.
* Set the mode switch to USB.
* Put in two-tone signal o f 1 KHz and 1.6KHz by two AF oscillators.
7) ALC alignment.
* Adjust the two-tone signal o f AF oscillator fo r 3 W RF power output.
* Adjust VR-11 for 11 W PEP RF power output when the two-tone signal is increased by20 dB .
8) Carrier suppression.
* Cut o ff the two-tone signal and make sure the output level o f the carrier is below — 40 dB.
* Set the mode switch to LSB and do the same.
