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

Okay... so non-technical doesn't even begin to describe me, when it
comes to electronics. I also thought my original problem was due to a
malfunctioning fetzer value and thought some gauze and ball-bearings
might do the trick (Fletch reference) :-)

In my defense, I looked at several sites for the part that matched that
part number, including some searches that included the words relay and
switch. A simple google search on "relay switch" comes up with an
entire page of which "relay switch" is used in the title or brief
description for every hit. I didn't look into the details of any one
link, but may have made a sub-conscious conclusion that the terminology
was valid.

Putting the relay vs. relay switch discussion aside, these groups are
an incredible source for someone to get assistance in an area they are
not comfortable. Even though I may come across as a moron at times, I
have gained a substantial amount of knowledge and most importantly have
decided to stop looking at my plane as a black-box, which reponds to
power and control inputs.

I will humbly listen to anyone who has taken the time to respond to my
posts and make a decision whether that feedback is worthy of follow-up
effort on my part or not.

Respond as condescendingly or as humbly as you want, just respond! ;-)
Advice on these newsgroups is free, but taking my plane in to an
avionics shop, I don't trust, to troubleshoot a problem that could
require significant hours of labor is not! I'll take what I can get!

Thanks to all and best regards!
