Anyone else noticing this. It started here about 10 a.m. The picture will pixelate for about a second, the audio will stop and it will come back in about 1 second.
It could be a tree limb but also could be an sw-21 switch going bad if that is what you have. Does it happen with both receivers or just one? Check your signal strength screen (press Menu, 6, 1, 1).
