Only addition I have is back to Bob's post. A channel that one considers worth watching really means nothing for adjustment. All you need is an active transponder on the sat you are
aiming at. A perfect example is out on 79. While many do not speak
Spanish the tp that holds KTEL (A Telemundo channel) will bury the needle when locked onto. So while you may not want to watch Telemundo it is a great tp for aligning when lining up on 79. Bout the same for all the sats. Some are empty but most have a church channel on them that is usually a wall to wall signal also. Although I have yet to get the famed GBN at anything more than a 85 on my receiver.
