Lately I have been hearing a buzzing noise on my scanners here at the house. I thought it could somehow be related to the fact they are close to the PC. It is hard to describe, but today I was at the pool with a portable AM/FM radio listening on the FM side when I hear the buzzing noise 2 different times. So Now I am confused on what it could even be, that is affecting my scanners and FM radio. It is not a constant buzz but more like some kind of morse code type, but unlike any I have ever heard.
