I'd have to find a cable tv chart, but I'd guess you're getting into a
cable channel that they have on the 2 meter band. This is actually a
cable problem, their system isn't as tight as it should be. As far as
cordless phones, possibly. As far as amps, I doubt it. All it would do
is hunm, but it wouldn't detect and let them hear an fm modulated career.
