I would try disconnecting *all* the antennas on the plane except
for the *good* com's (and the transponder's)

Well, but.. which is the good com? They both get the interference..

If you get the impression I'm not too thrilled about disconnecting
all the antennae in the plane, you got that right. Removing
avionics and leaving them on the ground is easy, for the most part
(and legal for me to do AFAIK).

Disconnecting some of our antennae is a cast-iron b**** and
reconnecting them is worse. Notably, the VOR/glideslope antennae.
Which brings me to ask...what does d/c'ing antennae get me that
removing their avionics doesn't?

I'm really hoping to hear from a couple of other folks on this
one, notably Jim Weir since I took his advice, drove to the antenna
farm, and found interference w/ my handheld.

What do you suggest next, Jim?

Yes, I mentioned this in my first post... get in contact with their
Engineering Department and explain the problem. They'd be *more*
than interested, they're technically qualified guys, and they have
the necesssary equipment.

Well, I did. I can't say they were "more than interested" in fact,
they were initially interested in telling me my equipment was at
fault because "we just had our equipment checked last Tuesday and
we're absolutely clean".

But I'm hopeful I eventually persuaded the guy I talked to
that if I could drive up to the foot of other antenna and just get
some strong RF noise on the aviation band, but drive up to the
foot of his tower stick the ducky out the window and listen to
a broadcast 5x5, maybe this bore investigation. At least he said
he'd call me back in a couple days and gave me his direct number.

We'll see...

Cheers,
