Do you use manual control (program 9) alot on your rotator controller or computer control (program 19) ?? I have found that using computer control is much better about this. When using manual control, I have observed a momentary speed up of the azimuth readings that do not correlate with what is actually happening on the tower - therefore, you end up reprogramming the controller for acurracy every few days. With computer control this does not happen.
