Every 10-20 seconds I get (as close as I can describe it) a super fast stutter or machine gun noise on one channel 6422 NBC HD Portland. Sometimes when this happens the picture pulls and pixelates. I do not think this is a receiver issue because the problem occurs on both my 622 and 211. I have sent an Email to dish, but as yet have not received a response. Is anyone else having this problem, or does anyone have an idea of a fix?
