I assume you have your system peaked properly for 79. If not you need to start there. With the entire system pointed at what you believe is true south for you have the receiver move the dish to AMC5 @ 79. Check
www.lyngsat.com for an active transponder and set your receiver to that transponder. Now slowly rotate your assembly on the mast until you achieve peak signal.
Now slowly adjust dish elevation for peak signal. Until you have your system aligned properly on 79 you are most likely not ever going to receive anything. A
motorized system is all relative to proper alignment to the center of the arc.
