Hi Peggy,
Actually, receivers do send a weak reference signal as part of the
process of ocking onto the proper frequency. This is a very weak
signal, and I wouldn't think it would interfere with anything, but I was
told by someone who knows a lot about avionics, that, believe it or not,
the radio navagation systems on airplanes are not shielded from
extraneous RF signals. That really surprised me when I heard it, and I
wonder if it is still true after 9/11.

You know, this talk of the GPS on airplanes reminds me of my last trip
to Portland on Southwest. I had no intentions of using the GPS on the
plane, preferring to keep the battery ready for use on the ground. But
during the flight attendants' information about what could and couldn't
be used in flight, they said anything "that sends or receives a signal"
couldn't be used during a flight. Obviously, a receiver doesn't send,
but it does receive. I was wondering if the regulations have changed
and people are just going by what they used to be, or if perhaps our
flight attendant misinformed us. Just curious.
