It's kind of a long shot, but I've seen it before.

That was the first thing I tried. I run into this ground loop problem all the time at work, so is it was the first thing I thought of.

I like 12 and 10 personally.
I do not care about other channel's digital transmit realm at all.......We are dealing with low power. it is an FCC "intentional RF radiator", true. But so is my garage door opener and my 802.11 N router...

Some of my sets only have three channel tuners so I have to use 1, 2, or 3.
