Advertisements I'm running a Tivo HD using ATSC antenna reception. Over the weekend one of my HD channels, 35-1 out of Richmond VA, kept going away, the screen was just grey on Tivo. I switched to my TV tuner (Tivo totally out of the equation) and the same problem was there, no channel 35-1. However, after some exploring I found channel 35-1 was broadcasting on 26-3. Why 26-3 I don't know. Later it switched back to 35-1, then went back to 26-3 again. The last couple days have been stable. Doubtless this is some sort of technical glitch on the station's part, but how common is this? Has anyone else experienced it in their area?
