Hello DBSTalk. Figured I've been a lurker long enough. I just wondered if anyone else has seen this issue. Quite frequently (maybe two to three times a week), both my 501 and 510 will go through a fit of "Acquiring satellite" events. Almost always between 12:00 and 1:00 am PST, and will last for about 10 to 15 minutes. At that time of night the receivers are usually on Science Channel, A&E, or History Channel. However, I can't say that it doesn't happen on other channels. Weather or any other factor doesn't seem to matter, just time of day. The only speculation I could come up with is Dish moving channels around on satellites/TPs. Any thoughts or experiences?
