Ah Yes Dimmer Switches, my parents have some dimmer switches in their house and I was staying over one night and I had brought my Zenith Trans-Oceanic with me to listen to some night time DX'ing and for some reason I kept hearing a bunch of hash noise on the radio while I was tuning across the dial and wouldn't you know it, it was coming from the old dimmer switch they had in their basement.
