FM radio tower near house

I had this same problem and wrapped my house in aluminum foil to get rid of it. My wife was really mad so I got rid of her too. Seriously, You need to figure out where it is getting in. I'd make sure my outlets were properly grounded. You can get a tester at any hardware store. If they are, disconnect everything from your proccessor except your speakers. If it goes away, reconnect things one at a time until you hear it. If you still hear it with nothing else connected, try shorting plugs (like the Cardas caps mentioned above)in the inputs. You can make your own much more cheaply by buying some RCA connectors from radio shack and soldering the center connector to the shield connection. If you have all of the inputs shorted and you still hear it, try a shielded power cord. If you still hear it, I think you are doomed. You could borrow a different proccessor to see if goes away. If you have to, move away or arrange an accident for the tower.

A couple of other sources for help: (1) much useful practical advice can be obtained in the "Radio Amateur's Handbook" published by the American Radio Relay League, an international organization of radio amateurs (ham operators). You might try the ARRL web page. Also, if there's an amateur radio club in the area, chances are there's a ham who'd be delighted to lend a hand. Radio amateurs are required by the FCC in this country NOT to interfere with radio and TV transmissions. Plus hams have their hown WAF issue: keep from blanking out the TV at home every time they trigger their transmit switches. Ham gear is authorized up to 1 kW transmit power, so the problems induced in a house are comparable to the problems induced by the FM station a few hundred yards away. (2) as an extension have you contacted the engineer at the radio station (every station is required to have a licensed engineer)? He or she may be able to offer some more specific advice about mitigating the interference. The level of motiviation to give you heip may be high, depending on what the FCC requires the station to do relative to avoiding interference.

I had the same problem and switched speaker cables to Canare 4S8. Bye bye RF!
