Hi folks,
I just noticed a problem with my Yaesu FT-736R rig. Everything seems to work fine in FM mode (both FM and FM-N), but when I switch the receiver to any other mode (SSB or CW) the S-meter immediately jumps to about S9+50 - not quite pegged - and I hear a full-quieting-but-no-audio sort of sound from the speaker. This happens on any band - 2m, 70cm, or 23cm, and anywhere in the band. If I tune to an active repeater and switch to SSB, I can tell that the FM signal is still there, but being swamped by something.
It's got to be an internal problem, but where to start? Any ideas?
