If you were getting PBS on RF 7, it might have been WCIQ (Alabama PB).
I'm getting even fewer channels today than two days ago. Most of the multichannel LDs are gone for me - among the bigger ones, I'm down to 28 and 32.
I guess I'm not the only one having trouble with WPXA 14.
After their move from RF 31 to RF 16, I'm having a much harder time tuning it (generally meaning that I can't without losing three other channels). While I was working on it, my receiver actually locked in 16-8 and 16-9 for a moment, which I wouldn't think would be part of WPXA's array. Is it possible that WYGA is still broadcasting on RF 16 and causing interference?
