All of a sudden, my system started acting erratically. I have all satellite positions stored with USALS, and the motor used to go from satellite to satellite just by changing channels - as it should. Now, if I go, for example, from 97W to 93W, the motor drives the dish all the way to 130W or 140W, who knows!! I've tried flashing the box with the factory .bin and re-scanning all sats, which seemed to work for a while, then the same thing started happening again. I have to change satellites manually. Any ideas as to what might be causing this behavior?
