I live in central PA and I have lost my locals in HD. I was on the Eastern Arc. Anyone else experience this? About a month ago, I lost my HD locals on their regular channel numbers (8, 21, 27, and 43), but I still had them on upper 4-digit channels. Now, they are gone, too. I still have the SD feed of the channels, but after you get used to watching network shows in HD you see a big difference.
