I'm right in the middle of the blizzard and my dish is covered with snow. I was picking up some OTA stuff, although my roof antenna is also snow-covered. Then I made the mistake of tuning to a sat channel. I got the "Acquiring satellite signal" screen, and can't get rid of it to go back to OTA. It is just running through all possible transponders, with no sucess. My receiver is a 622 and I'm looking at satellites 61.5 (spotbeam for Washington, DC locals), 110, and 119.
