I'd totally forgoten about the house wiring. But, when I ran my scope with a
1' wire in the input BNC, all I saw was the secondary fundamental. I don't
think that the TC fundamental is causing the problem. The spark gap,
however, acts just like an universial motor's brushes and radiates everywhere!

The interesting part, my own TV was only showing slight line noise. It's
only about 10' from my TC! On the cordless phone it could just be heard. I
could hear it on my AM radio 6' away, but I'd expect that.

I just tried it again. With my wife and son watching "The BookMaster" on the
VCR. She didn't see any snow, with or without the choke. Must have been some
radiated noise.
