set your antenna to receive sats 61.5 and 72.7,third sat is 77,however if you just get 72.7 you will get just about every channel in HD 61.5 carries locals on east coast and a few SD channels sat 77 is all spanish as near as i can figure,I now just use one lnb on a dish pro plus 5oo and aim at sat 72,the way i get the dish settings for aiming is in the point dish mode put in dish type 300 (the old single lnb dish) and sat61.5 now elevate the dish about 5 degrees and aim about 5 degrees to the right of 61.5, you will get all your HD programming!
