[QUOTE="jeallen01, post: 1149449, member: 176704"] I would suspect that the longitude issue could possibly be related to one or more of the following: 1) the nuts on the U-bolts fixing the motor to the house "pole" are not tight enough, and thus the motor is gradually shifting slightly around the pole due to the "inertia effect" when you send the dish a long way West, and then a long way back East in one movement? 2) Similar to 1) but for the nuts on the bolts securing the dish to the pole on the motor itself 3) "backlash" in the motor is building up and so the backlash adjustment needs attention? 4) the ground under your house isn't stable, and so it's very slowly moving a bit East & rotating a bit "clockwise" at the same time:-rofl2 My "bet" would be on No 1) above!:) [/QUOTE]
