Interesting on the USALS. I did upgrade the firmware to a revision dated last spring. This being a bonafide Viewsat revision of course. It took fine. Does the USALS swing the wok full east-west as part of its autoconfig (like a TV rotor)? If so, I need to adjust my hardware limit to the east first as the dish hits the wall at about 60° east and the motor goes to 70° east. I'm sure it has enough torque to damage things.

No switches in-line, just receiver-motor-(linear)LNB. The LNB was working 100% when I removed it in August too. I have a spare anyway.
