RE: Dish receiver causes speaker hum with three prong plug?

That gadget Duster recommended won't work anyway.
Among other things, that's a DC-blocker and your sat dish needs the DC excitation voltage for the head-amp. When you install it your hum problem might be alleviated, but you won't have any TV. :)
