I've got the worst ground-loop noise thanks to my DishTV HD receiver... and I've tried almost everything I can to fix it. I'm *confident* it's from the Dish Receiver - as soon as I unplug the coax, the noise goes completely away.
Here's what I've done:
1. Bought a Ground Block from Radio Shack, wired a 10ga ground to my water pipe, and secured the ground wire to the pipe with a metal hose clamp. Noise still there.
2. Bought a Jensen Ground-interrupt, installed it exactly per instructions, and still had the noise. Connected it through the Ground Block, and noise is still there.
3. Bought a Furmann noise-filter and power conditioner. Noise still there.
4. Installed a cheater plug. Noise still there.
5. Used the ground-lift setting on my amps - noise still there.
6. Bought an inline coax filter, and the noise goes completely away... but so does the picture - everything goes 100% black as soon as I use it.
I'm using optical audio cables, and all of my components are grounded to the same source (except for the satellite dish, obviously).
Anyone got any ideas? It's driving me absolutely batty.
