Hi Roger, my name is Danny. Your intermitant audio and tx problem sounds
like
the reed relay on the low pass filter board is becoming intermitant.  To
verify 
this the next time your audio dissapears, try giving your rig a good hard
smack
on it rear end on the top of the case next to the final amp heat sink.
Don't worry
about giving it a good one because we will do it if you send it in to us.
If your audio
come back, then bingo the relay is the problem. One thing does concern me
however,
the snap you hear. That sounds like something in the final amp itself or
possibly
on the low pass filter board. My suggestion would be to send it in before
it
creates more problems. But call the repair department and talk to Don
Prouty.
He can give you more insite to your problem.
see ya Roger and take care.
