How old is the backup battery in each of the respective Orions?
That might be a good next step to try, even if the battery is
not that old, ... still cheaper than a trip to TT ...
(Other ideas might be master resets and reloading firmware)
Hope this helps!

Subject: Re: [TenTec] Orion II Problem
I have been experiencing the exact same problem for months with my Orion 565.
It started out mostly only on 20M and would clear up if either changed bands or
cycled the power. Then it progressed to other bands as well and now does not
clear up regardless of what I try. It affected only the main rcvr, the sub was
fine. Listen on a separate radio to see if it also affects the transmitted
signal. In my case the transmitted CW signal sounds just like the received
signal audio, warbly and buzzing almost like a spark gap signal!. So I'm
guessing it's somewhere in the local oscillator/IF chain. I've talked to TT a
few times and there's no way to diagnose my symptoms without getting it on the
bench.
Currently it's sitting on the shelf unusable while I decide how much I want to
spend on it. Good luck. If you think of it, drop me a note if you resolve the
problem.
