[QUOTE="guest, post: 575561"] Could be any one of, or several of, quite a few things. Firstly, how have you measured Azimuth? Doing it with a Compass is not at all accurate ................ Secondly, you can only ever use things like Motor Latitude setting, Dish Elevation setting as guides - it simply isn't possible to set them dead accurate "by eye" as it were. They are used as starting points for manual micro-alignment. Thirdly, however accurate you think you've been, whenever you tighten a bolt or a clamp, things tend to shift a bit. Fourthly, you don't say what size Dish you are using, but if it is 80cm or below, then the Beamwidth is not that narrow, so if you are a degree or so out in Azimuth you would still get a strong Satellite like 9E. A bit more than a degree and you'd find that 13E would begin to dominate. So ................... don't worry to much about exactly why, just shift the Dish/Motor assembly around the pole a tiny bit further East to get on the correct Satellite! [/QUOTE]
