Do you hear music coming from the furnace or A/C? I have always heard music, far away but not garbled, when the furnace or A/C is on. Since like 30 years ago. So it doesn't depend on the house I am in.
The house in which I used to live was 1/8 mile from an electrical substation across the railroad tracks from the west campus Motor Pool of NCSU. When I would pug in and turn on my guitar amplifier, I would get the NCSU student radio station playing over my amplifier.I couldn't figure out how this was possible. Now that i live farther away from the old house, it doesn't happen any more. Anybody out there with any ideas as to why this occurred?
