I finally got my 39" motorized dish installed, on the side of my house, mounted to a very rigid sil plate. I locked in on a true south satellite and eastern and western satellite. Then I did the "all satellite search" which was successful. I browsed the channels on each of the satellites and the signal on all of them was 90 and quality was 70+. Then I programmed in a couple of eastern sats e.g. 34.5 West Intelsat 903 Ku-Band, etc.. Sats that are not pre-programmed into the Sathawk PVR800. I was getting no signal on 3 or 4 sats that I tried, figuring that maybe I won't on the most eastern sats, even though I have a clear view. Then I went to the sats that I previously programmed that were pounding a signal before. None of them had a signal! And I varified that all of the sats had no signal. The dish moves just fine. I went out back to make sure that the dish mount pole didn't drop or somthing. It seemed ok. What the heck is going on here. I did not do any firmware updates, so that is not a factor. Any ideas anyone?
