[Icom] IC- 706 MK IIG Antenna Connector Problem

Well...  Radio Shack's motto is:

"You've got questions? We're clueless!"

Nothing but a bunch of low-grade junk there...  unless you want a cell
phone.

Sorry, had to get that off my chest...  The Shack ain't what it used to
be...

Subject: [Icom] IC- 706 MK IIG Antenna Connector Problem

Hello All,

I have a new (less than three months old) IC-706 MK IIG. When I attach a
new Radio Shack PL-259 cable (with crimped connectors) from my SWR meter to
the SO-239 on the back of the rig, as soon as I insert the center piece and
start screwing on the shield, the signal drops appreciably and I can barely
hear anything at all. As soon as I loosen the shield and barely have it
connected to the rig, the signal reappears at the proper volume. The cable
has no shorts.

When I tried an older cable with soldered-on connectors, the signal stays
loud until the very last turn of the shield when the signal drops similarly
to the new cable which has crimped connectors. It has no shorts as well.

Any ideas on what may be causing this?  One guess is that the center pin of
the connectors may not be thick enough when making the connection. Could
the SO-239 be bad? Is it safe to operate with the shield not fully
connected? I have a low SWR with it < 1.25:1.

73,
