Would a heating pad cause RFI ? My wife has intermittent back problems
and when she uses her heating pad it seems I get spikes of RFI on my
AM reciever. I'm assuming it's that. I can't seem to track anything
else that may be causing it.Thanks in advance,

A snubber across the contacts should stop the RFI. Try a 0.01uF 600V cap in
series with 47 ohms. If you don't have a suitable 600V cap in your junk
box, look in a discarded PC power supply or monitor. The AC line input will
have 250VAC caps for RFI filtering.
