+1. You would be amazed what can cause interference. We had a service call at work for an audio system in a spa. It would buzz and crackle randomly. I scheduled a time when they were closed and started replacing gear. After I replaced everything and the problem still persisted I stared unplugging their equipment. Finally I unplugged the machine that was supposed to shoot ozone (or something like that) onto your face. The machine wasn't even on, but as soon as I pulled the plug all the interference went away.
