[QUOTE="jeallen01, post: 1104095, member: 176704"] I had to slightly adjust (AKA "fudge") the arc on the Gibby by about 0.3-0.4 degrees to get a really solid lock on China Radio on 45W, as well as almost all the other sats across the arc - but those are minute amounts which, as I said earlier, would be almost impossible to eliminate by the adjusting the setting of the motor on the pole. Don't forget that, as the dish sweeps further and further E or W from your Southern-most sat, the sats are further and further away and thus, whilst the [I]angular [/I]difference between them doesn't alter as far as the motor is concerned, the actual "physical distance" on "your horizon" [I]does[/I] increase a bit - and therefore so the dish needs to be pointed more precisely at the orbital position (and the signal gets weaker as well in most cases - especially when on the footprint fringes). TBH, I don't think you'd get "much better" after a lot of long and tedious, and often counter-productive, work as the "law of diminishing returns" will come into play. [/QUOTE]
