I would use the above angles and set up for your true south satellite your true south is the same as your latitude 90 deg W (or as close as you can to it). You will need a compass then enter the below transponder/channel and watch for quality level on your TV screen, SLOWLY moving the dish from east to west, once you see any quality peak the signal as much as you can then do a blind scan, leave your LNB straight up and down for now but it may be moved closer or further away from the dish during the peaking of quality.
