Hello,

I have an Icom IC-765. Recently, after we moved, I setup a random longwire
antenna up outside and coupled it and ground to a length of 213/U and
attached it to the SO-239 port on the back of the 765. I got absolutely NO
receive signal/sensitivity whatsoever. Even on 10 and 15 mHz. I knew this
could not be right. I checked the coax and PL-259 for a short - no problems
there. I attached the antenna to another receiver and it was definitely
pulling in signal. So, I then rigged an RCA phono plug and attached the
coax center lead to the Receive Only Antenna jack just below the SO-239 and
the receive signal shot to a full quieting WWV signal on both 10 and 15
mHz!!

So, clearly something has happened to the antenna path from the SO-239
inward. I popped the top and could see no visible solder breaks in and
around the SO-239 backside. I suspect that the problem is occurring
somewhere in the antenna tuner (well, maybe) as I think I understand that
the receive only antenna jack bypasses the antenna tuner.

Has anyone experienced this before? is it fixable by modest mortals? It is
a pain (and $) to ship the unit to Icom, so, I was hoping someone here might
suggest some possible things to try first.

Thanks!
