Paul et al:
Thanks, I did not specify any details regarding "conditions" for a
purpose. Yes agreed, some conditions will accelerate oxidation. In
re-reading my post, it was not clear on the laws of chemistry and
physics. It should read "......has to do with the conditions......"

Beg to differ on some of that, Bob. Moist and high temperature
environments will accelerate oxidation as will some environmental
contaminants.
Best Regards.

Seems that I keep preaching this topic over and over and over. I
recently addressed this issue on a Scout and a Century 22.
Fact is, connectors oxidize. It is the laws of chemistry and physics
and has little to do with the conditions where the radio resided,
past
or present. When connectors oxidize the electrical path is
interrupted
by the thin layer of oxidation.
The solution is simple. CLEAN ALL OF THE CONNECTORS. Thus removing
the oxidation and the radio returns to normal operation. Just
be sure
to exercise the male connector on the female connector a couple of
times
and then be sure the connector is correctly and fully seated before
moving on to the next connector.
As to the cleaning process; a Q-Tip with contact cleaner applied,
{your
choice of the magic chemistry} and then scrubbing the male pins is
all
that is necessary. No hocus pocus, black magic, or voodoo act
required. And while you are in there.........DON'T screw with
anything
else.
