We are not having luck, either. We have tried
12000 /H /04880
12000 /V /04880
12001 /V /04880
blind scan search several times (takes >5 minutes)
When we try the vertical ones, we get a pretty high "signal strength," quality 32%, then when we say GO, it doesn't find a TV signal.
Any suggestions? What made you try frequency 12,001?
I am at a friend's house. They successfully watched Sioux hockey last year.
