I'm considering getting my own Eastern Arc dish. I have always installed my own dishes. I just noticed that in the "Point Dish" screen the only orbital locations with zip-code based coordinates listed are 119. 110, 148, 105, 121, and 61.5. While I can set it for 72 & 77 I get "n/a" for coordinates, no matter which dish I select. BTW: there are only 3 dishes to chose from: 300, 500 & Super. No 1000.2 or 1000.4 listed. With all the software updates you would think they would have included the coordinates for the latest model dishes. I wonder why they left off the coordinates for the current model dishes? While I have a 622, this may be an issue for other models so I'm posting it in the general Dish discussion area.
