Ultimately the goal is to get all TV broadcasting off of VHF channels
- the government wants to auction off those frequencies, or perhaps
give them to Haliburton :-)
During the transitional period there may be some ATSC on VHF, but it
should be an uncommon situation.
I still think trying to use both sides of the HD-3000 isn't worth the
effort, considering how cheap an NTSC frame-grabber is.
