I'm wondering if someone might shed some light on a problem I'm having. I have a Viewsat Ultra driving a Stab HH 90 motor. It tracks the arc flawlessly from 72.0 -125.0 W BUT when it moves to 125.0 and 1 or 2 others, the picture comes up, but then the dish moves off, presumably goes to its limit then comes back. It doesn't make the thing useless, just makes it take forever to change positions and channels. This is especially noticeable on 125.0. The dish is out of view of the house, so I'm not positive what it's doing, but I think it goes to 125, moves off to 72, then back to 125 and stops there. It's a single LNB, so it's not getting conflicting commands from another receiver. Any suggestions?
