Symptom:

Any of the following: Cannot change band to UHF, no UHF volume or squelch control, no UHF tuning, or strange-sounding beep tone.

Cure:

Rework bad soldering at J3 on display unit and replace the SW-B board with a factory-modified flex PC board.


Symptom:

No audio output from receiver.

Cure:

Remove excessive solder on the Main-A unit near the audio amp.


Symptom:

Howling if volume is turned up when using UHF.

Probable Cause:

Microphonics in VCO section. Resolder the ground spring at the UHF VCO shield. You may also add a second spring for further improved resistance to microphones.
