Hi Carlos, I have found a source of a noise similar to what you are experiencing. Turns out that my electric company uses one of those electric meters that has a digital readout and it automatically sends my usage back to their main office I am assuming over my service wires. I found this by using a portable radio and when I get near my meter base, the noise is that strong it drowns out all reception. Even when I’m several feet away, I can still hear the noise in the background. I also have a lot of noise when I walk by my flat screen tv even when the set isn’t on, although it could be from my cable box or modem. Hope this helps.
