Hmmmmmmm, lets see. Most list members recommend connecting to the ship's
antenna, as do most folks in the know. King, PS and others make a
box/device to easily connect your HH to the ship's antenna, and Kitplanes
has featured a do it yourself model. But the nice ICOM National Sales
Manager says that it doesn't need to be connected, so that sounds like a
keeper to me! ;-)

Hi Everyone,
I just reached Rick Waedekin, ICOM's National Sales Mgr., by phone. HE
said:
1) The ICOM A-23 does NOT need to be wired to the plane antenna to serve
as
effective cockpit backup.
2) The bad transmission I described (when I just plugged headset into the
supplied adapter and tried to transmit from the cockpit on the ground with
engine running) is the result of having 2 mics both trying to work at once
(the one in my headset + the holes on the front of the ICOM itself). He
said all I should need to do to solve this is to go buy an external PTT
switch, and plug it into the 3rd receptacle that's part of that supplied
headset adapter (which I erroneously had thought was just for patching in
music from an external player). He said that an external PTT switch is
wired to disable the mic that is built into the front of the ICOM (little
holes) so that my voice goes ONLY through the mic in my headset. Then,
use
the external PTT switch to transmit. That will avoid the feedback whine
and
extreme garbling that happened when I tried it without this external PTT
switch.
3) Yes, the ICOM A-23 should both send and receive fine from the ramp to
Ground Control & Tower. I only tried that once today, but if it
continues,
and I want to test it, I can do so by trying another rubber duckie or by
wiring it to the plane antenna (he said only do the latter if my plane
antenna is on top of the plane, which it is).
4) If my transmissions are still too weak for Ground/Tower to hear me,
there's a 3-yr warranty; send it back in to be checked.
I also want to say how very nice he has been in all of our communications,
and how very accessible (making allowance for the fact that they're in
Oregon, which has been snowed in, power outages, etc.).
Linda
