Last night, I got home and my 722 was "searching". Nothing. I went to point dish, and had ZERO signal on all 3 sats. Tried a check switch, nothing. I thought I'd have to go out today with the ladder and re-aim the dish, thinking it got hit with something falling from a tree or what.
2 Hours later, back to normal like nothing happened. Great signal on all three sats. Go figure!
