how to eliminate air-born RF

any ideas on how to eliminate airborn RF. I have disconnected all equipment from themselves and the ac outlet. Even shut off the main circuit breaker in the service panel. Have disconnected all video cabling and antenna wires. after all this, when I place my head behind my rack, which just holds my amps, I can here a humming noise similar to the ground like hum you hear from an electric guitar/amp combo or similar to a bad tonearm phono ground loop. With system wired up and operational, this humming is easily heard at idle on, with gain on preamp down. Again, this is occuring with nothing physical wired together or to the ac outlets and with all ac power shut off in the house. PLEASE HELP!!!

Assuming that Edesilva might be on the right track about a very strong electromagnetic field (EMF)expanding and contracting at 60hz frequency from a rogue external power equipment, your speaker cables can pick up that like a wire-loop induction. If your speakers are efficient enough it might be playing the hum all day long without your amp turnon. I can be wrong, but try disconnect your speaker cables and see if the hum is still playing.

I do hope I'm wrong in this intriguing Mooncrikit case. There were many health concerns raised by people who live near sources of EMF recorded by Mark A. Pinsky in his book "The EMF Book" 1995 Warner.
