I know that you have checked out the cables, but it does sound like it could
be a problem at the antenna end if it is not the the cables themselves. The
fact that you can receive signals when the plug end is only halfway in
illustrates the fact that the receivers are probably working properly. Could
be a short to ground at the entenna end. I am assuming that when you checked
the cables you did do an end to end check with an Ohmmeter, both for
continuity and for center conductor to the ground shell for a short circuit.

I have an R-2000 and 830S by Kenwood.
Both radios do not receive when plugging in coax connectors into the
S0-239 receptacles. I've eliminated the cables as the problem. I
believe it is possible salt air corrosion internally in both radios.
The signals and noise drop out completely when screwing in the PL-259
connectors all the way in and tightening them down. When they are only
half way plugged in I get normal reception when wiggling the cable but
they are not screwed in completely and not making a good electrical
connection. I lived on the beach and sometimes would open the windows
for ocean breezes. The 830S was right next to the open window and the
R-2000 was sitting on a night table a few feet away from the open
windows. I've eliminated the cables themselves and suspect salt air
corrosion internally in both radios.

Is there a spray contact/solder connection cleaner available on the
market that might help solve this problem?

Recently I had the S0-239 replaced onthe 830S and still have the same
reception problem. The noise and signals drop out completely in both
radios when screwing in the coax connectors (PL-259) completely.

Thanks for the help!
