Not sure if this has anything to do with anything, but our local Media General Station (WKRG) has lowered power for some reason. Signal that has always come in at 100% is down to the 80-90 % range. Not sure of the reason, unless they are trying to make sure some Dish Customers can't get them via Antenna. Which will make customers more demanding to Dish to get them to cave on negotiations. Lowered Power means areas further out will not get the station reliably.. Or they could just be having a power problem or saving money.. And again this is not the DMA you are in. Just am not putting it past Media General to pull this stunt in ALL DMA's if they thought it would help their case.
Edit.. Although today it seems as though they have turned power back up to full. Might be Tropical Weather coverage or they fixed their problem.
I'm not sure the FCC wold let them do that sort of thing.
