I have a Coolsat 6000 premium receiver, a Stab HH90 rotor, a FortecStar FC-90 dish and an InVacon Quad Polar 40mm horn LNB. I live at Austin, MN 55912. My latitude is 43.7, Longitude 93.0W and dish elevation at 38.3. I am trying to lock in on IA 6 93.0W. In mrweather's reply to jsattn on 12-13-06, he mentioned to have the motor at TS (0 degrees). Does that mean that it should be at 0 degrees when aimed at IA 6? After entering the above information, my dish motor always stops a few degrees west of 0. Sure would appreciate some help. Thanks.
