If I were you, once my pole was perfectly plumb,
1) Set up your motor and dish at recommended angles to start.
2) Point the dish at what you think is true south, and loosely tighten the mast nuts.
3) Set the parameters for AMC5 in the dish setup screen using as a default transponder 12182/H/23000 3/4 . This tp is pretty much always active.
4) Go to the motor control menu, use USALS , enter YOUR latitude and Longitude ( be careful about the East-West North-South settings) , and tell the motor to "go to position". The motor should move slightly.
5) The receiver now "THINKS" that it is pointed at amc5 . Your job is now to adjust the azimuth( east-west) of the whole assembly by just barely moving it one direction or the other, to improve the quality signal, and THEN adjust your dish elevation setting , a little at a time to maximize the quality signal.
This is all much easier with a small TV and receiver out there at the dish with you.
6) Once you have maximized the quality ( and have a nice number there, like 60% maybe) scan the bird and see if you get any channels , you certainly should. Then I'd set up G10R at 123W on the dish setup screen and tell the motor to go to THAT position. If your setup is perfect, you'll get tp 11805 with decent quality. If not , go back to tiny adjustments( sometimes just leaning slightly on the dish , one way or the other will tell you which way to move it.
7) When you are finally done, you should be able to hit all the linear birds in range simply by selecting the satellite, USALS will take you there.
Good Luck
