I have developed a problem with my 7000 in the FM mode that seems to be squelch related. When listening to VHF FM, the squelch does not produce the usual background noise when un-squelched. When turning the knob, the red light indicating a received signal does have a threshold, and signals seem to come through the squelch. At first I though it might be a loose speaker wire, or button that go accidently pushed.
Does anyone know what is going on?
