The fcc is working with WLS here, as many are not able to get them now as they are running on channel 7 now digitally. Their digital signal is about 1/4th of the power that the anologe signal was.
Well, just found out during last nights thunderstorms that VHF is MUCH more sensitive to thunderstorms that UHF. Every lightning strike would pixelate a little bit, even with signal quality solidly in the 80's on my Tivo HD. Ugh. I wish they would have just stuck with UHF.
