Just wondering if anyone else has this type of noise going on as I'm scared its only me! The noise is not constant in tone and pitch as in its not a constant Eeeeeeee or hum, although there is Eeeeee in it. Its sort of has movement in it, like sliding up and down in pitch and it can move sort of in and out, it sort of sears in then backs off. All this within a couple of seconds. It sort of plays a tune. Not a real tune but going up and down all the time. I dont think it covers many pitches. The best way I can describe it is when you're trying to tune in a radio and it comes close to a station, but not on the station. So hard to describe it. There's also some background static noise but I know other people get that. Its this moving sound that I want to know about - if anyone else has it?
