OK, I got my 40" Primestar dish up and running on my Stab motor. Using my Fortec Ultra receiver, I can move the dish across the arc and pick up all the birds I'm interested in. But when I'm watching TV, and want to switch to a channel on another satellite, the dish doesn't move. The only way I can change satellites is to go to the antenna setup menu, go in under 1.2, and enter movement to east or west. I know there's gotta be something simple I'm overlooking. What is it?
