John,

The advice about rf floating around your cockpit is all good.

With a good radio/co-ax/antenna the B40 with DAD should not be having
any transmit troubles.

We had one B40 in an ASW19 in Japan that had a similar problem which
was traced to improper termination of the BNC connector on the coax
where it plugged in to the radio. Fixing the coax problem made the rf
problem go away.

When putting a BNC connector on to a piece of coax refer to the
manufacturers' instructions. It isn't at all obvious how it should be
done properly.
