The other devices may have circuits that incidentally radiate a little
noise in the aircraft VHF band.
A broadcast FM receiver almost certainly has an oscillator running by
design, in the band.
Where it lands in the aircraft band, is determined by where it's tuned to.

Ah... you're thinking... FM broadcast range is 88-108MHz... with a 10.7MHz
IF... a high side LO is at ~98-118MHz, easily landing within the aircraft
band (which is... 108-??? MHz, right?).

The original poster is long gone -- refused any info and advice we gave him
including a list of airlines that prohibit AM/FM radios and other devices
And the FAA stance on the matter
Must have been 50+ responses
So I guess we can put this to bed
