Still something loosing contact somewhere. A component failure wouldn't
normally respond in that manner.

Thanks for the reply, Bob. Yes, I've done all the connectors with
De-Oxit and I thought that did the trick, but the howling noise came
back after about a week.

Have you done a recent "connector cleaning"?. If not, I'd say it is
time to do so. Just sitting there, internally the connector contacts
will oxidize after 30 or so years.
So, one at a time, unplug each connector, then using a Q-Tip
moistened with contact cleaner, scrub the male pins. Then plug the
connector in and out a couple of times to wipe the female pins. Be
sure you have aligned the connector correctly and that it is fully
inserted. Move on to the next connector. Usually this method will
correct a very large part of intermittent and strange issues.
NEVER spray anything into the radio, connectors, IC sockets and such.

Hello Gents--
I have a Ten Tec Omni VI that has an intermittent problem that comes
and
goes for no apparent reason. The radio can be transmitting or
receiving just
fine and then a loud howling noise comes on. When the noise comes
on, all
functions are lost (signal reception, mode selection, band change,
audio
gain, etc.). The radio can be turned off and then back on with no
change.
Resetting the processor doesn't help. Shutting the radio down for a
day or
so will bring it back to normal again. Normal operations may
continue for
days or weeks before the howling noise appears unexpectedly once again.
I've found that pulling cable #56 on the Logic Board will stop the
howling
noise. Plugging cable #56 back in restores the howling noise.
Has anyone had a similar problem with the Omni VI or can anyone give
me any
guidance on how to go about repairing the radio? Thanks.
