I have this static problem that comes and goes. It will stay for a few hours or a day or so. then none for a few days. I have a old laptop. PSR-410 and a Radio Shack Discone it is in my attic. All connections are clean. Also seems to happen more in the evening or early morning hours. In the next few days when I hear it I am going to try to move the PSR 10 or so feet away from the computers and the laptop it is running on. Anybody run into this sound with their setup.
