Cheers,
Far b3e it for me to correct Bob Nuckolls useful and accurate
assessments, but I beg to add a caveat to the following:
I think your risks are low. I've used these devices
for decades in some hi-end aircraft and industrial
applications with no difficulties . . . however,
having said that, I've NOT tested any of these things
in the RF lab . . . The major threat is from transmitters.
Play with one on the bench while irradiating it with
a hand-held and rubber-duck antenna from about a foot away.
If keying the transmitter doesn't affect operation, it's
probably going to be just fine in your airplane. This
kind of exposure from a handheld is MUCH more than
it would see in a typical installation.
>> unless that 'typical installation' contains a radiating antenna<<
Forgive me Bob.
Happy landings
