Can anybody explain the settings for the Pansat 2500 using USALS. I looked in the manual for the Pansat and the directions are vague. I'm set for SBS6 my most south sat. I set the L & L. For me it is 75W 40N. I have no idea what the "Reference Position" is for or what it does. After I put my L & L in it moves my dish back East 1 degree and my signal drops. Does anybody have any idea why it does that and how to compensate for it other than getting back on the roof and moving the dish/motor to the west 1 degree to bring the signal back up? Please Help, I'm tired of going up and down the ladder......
