You might also try twisted pair cable, that too helps reduce crosstalk
between parallel conductors, you can get shielded twisted pair as well, I
had
simmilar effect in one of my cars once, High power AM cb radio with the
aerial
directly in line the the ignition coil, About 50% of the time the CB would
cause the engine to miss fire when you keyed the mike to transmit. I ended
up
turning the coil on its side to stop it happening. Thats why most countries
have minimum separations and crossing at right angle requirements where
phone/data
cables are close to high voltage AC lines.

Hi Jim,
I tossed the GRT supplied harness and used a pair of shielded cables.
I seem to recall that I used a 4 core and a two core. Any how I
grounded one end back to my central ground point, and for each cable I
used a small toroid. I was able to get an addition loop through each
one although it was tight.
My suggestion is that you try the same for your ELT wiring. I know
that you mentioned that you were already using toroids, but try an
extra loop through for each wire, and add a large one over the whole
cable. If that doesn't work, replace the 4 core flat telephone cable
with a 4 core shielded cable.
I have a bunch of toroids left, let me know if you would like me to
toss a few in the mail. BTW, I am using a Bob Archer antenna. It
isn't much better, lots of stuff goes nuts when I transmit.
Cheers, Paul
