I keep losing singals when watching channels on 61.5 and 72 on the Eastern ARC install. There was a 1/2 of snow on the dish so I cleared that and thought it might be the problem, but after 20min - 1hr, I go to switch channels and there is no signal. When I push and hold the power button on the 222 tuner, it goes through it's thing and finds all the signals again. Is this a Dish problem or something on my end? Thanks!
