Avionics (Radio Problem) Narrowed Down... I Think???

The info off the relay says:

Thanks!

And I can't find my old P&B catalog to save my soul. It may have been a
victim of one of my "haven't used it in twenty years, throw it out" library
purgings of last year. Best I can find is that it is a 3 pole, double throw
relay. That sort of gobs up the works, but we can still find a replacement
if you will tell me how it connects into the panel. Is it a plug in? Bolt
down? Can you take a picture of it and post it somewhere? We can cobble
anything if we know the form factor, even if it means three SPDT micro
relays in the same space.

Thanks for looking Jim!

I found a link for someone that sells components and requested to have
a relay shipped to me. I'll probably put that one in and keep the
other one for a backup, although I'd be surprised if this is a common
problem given the number of Cessna audio panels that are out there and
still working...

I am probably going to try and find another audio panel, with marker
beacons and the componentry to support another COM, so I can throw one
in some day. I'd love to bite the bullet and upgrade to a newer audio
panel, but that would require a rewire and would be quite expensive!
What I have in there now serves my purpose, when it all works!!! ;-)

Thanks again for all of the input! I will post an update on how things
go, once I've had a chance to replace the relay. As for the immediate
problem... it has not come back, since we fiddled with the current
relay, although, I've only got about 3 hours of flight time since.
None-the-less, I wasn't getting that much functionality out of it, when
it was intermittently working!

Best Regards,
Todd
