Well , your going to laugh at me. But here goes anyway. Saturday Feb 10th I went on my roof. Yup, still no 83W. So I hook up my ten dollar signal finder, and it's buzzing so I have power. I see there's a bolt loose on the dish for the horizon, but the other side is tight. As I'm looking down the poll to the ground thats about 15 feet long, I can see its flexed a little, so I grab the top of the poll and gently pull it East, and my signal meter goes crazy. So I adjusted the turn buckles on my poll/shop to remove the bow, and sure enough, I now have 83W. All this happen the same day I installed the two other dishes, and about the same time others had problems getting 83W.
