What is your southern most satellite? I had assumed that it was 87, but if not go to the southernmost for the steps.
1.) Get the antenna as close as possible to the Zentith, the mid point where the aim is highest. At this point the dish should be pointing to True South. Depending on which side of True South your southern most satellite is, figure out how many degrees it is away from True South. Then figure out about how many counts on the actuator per degree and move the dish that far in the appropriate direction.
2.) Pick an active transponder on the southernmost satellite and peak the antenna for that satellite. It is just like the Ku band, move the dish by hand and see which way the signal goes up or down and adjust accordingly.
3.) Once you have peaked the southern most satellite, then go to each extreme and watch where it falls off signal wise. If you were good or lucky, you nailed the due south and everything is a go and you are pretty much done except fine point tweaking. If not, you have to repeat the steps making fine adjustments on east-west and elevation wise on the southernmost satellite.
When on the east and west extremes, remember that if you push up on the dish on west end and the signal improves then dish is probably pointed a bit off to the west. You can confirm this by going to the East extreme and repeating the push test and if the signal increases when you push down on the dish. If not, then your declination could be off.
C takes a bit more time, because you have to work your way across the arc going from center to each extreme satellite by satellite and identifying as you go. While doing that take notes on Q numbers as it might help in telling which way you have to move to get it.
Hope this helps you out, and remember to be patient.
