Quick progress report.
After deleting KB4103718 and resetting the rotor position change to 3 degrees, I have not seen a stall in a week. I will open that out a degree at a time, and see what if anything happens.
73,

One was showing <the elevation at 4 degrees, with the target at 0. The Labjack server was <indicating a down command. I closed and restarted SatPC32 and when I <selected Park, it dropped to 0 and the desired azimuth. The second time was <an azimuth problem, with a large difference between the commanded and <actual position. The Labjack server was indicating a turn.
