I moved it 2 degrees and now it does not find any satellites. Doesn't zero need to be aimed to my exact south?
No. I had to slip my SG2100 a tad to get it aligned onto the arc. The USALS is a little off, but the diseqc 1.2 is spot on. I use the USALS to get me close to the bird, then I nudge it using fine control and then I lock it's position into memory.
There is a way to adjust the USALS, but I never bothered with it.
1. It does not overrun zero. It only starts doing it 10-12 degrees either east or west of zero. The farther from zero, the move overrun.
2. It will program via diseqc 1.2 and returns to the place it was programmed to within about a half of a degree.
Since it does go back to the place it is programmed to with diseqc 1.2, I take it this motor is not USALS compatable? Any suggestions on a USALS motor that works with a Winegard 30"?
It sounds like you already contacted support and now have an RMA to send it back in. The motor may be bad. After they check it out, it will eliminate one variable.
