Does anybody make any kind of shielding for Radio Frequency Interference? I have mounted my Crane HI-6 under the passenger seat and am now getting static through the radio.
Try this first: wrap the offending piece in aluminum foil (it's temporary, so don't worry about heat). The foil shields against RFI, and you can at least check to see if it is emitted or if it is travelling down some power wires and such.
