Have a IC R100 communications receiver which now has a fault
Turn on unit and reset CPU OK
Unit comes on ok and I can select a frequency to enter and it pulls up the frequency (beeps out of speaker for each push of a button)
But no RF nothing on S- Meter nothing out of speaker
Turn up volume all the way nothing out of speaker not even a hiss!
If audio problem why no S-meter reading? And if not an audio fault why no hiss?
Any one has any ideas
