(magnetic south -11° for Tucson) - Okay, with the above info I am able to get a very strong signal from EchoStar 8 which is 110°. My Long is 110.99°W. I used USALS to point the dish to EchoStar 8 but had no signal till I adjusted the dish elevation to 36 from 41.26. Why?

A couple coments and a question. First, I would have recommended that you use 32.6 for your latitude, and 4.6 for your declination, as a starting point.
Second, just to be sure, is the magnetic heading you are using 191 or 169? Ie did you add or subtract the 11? I assume 169.
Third, some motors have both a latitude scale and an elevation scale. If it has both, make sure that you used the latitude scale rather than the elevation scale, because that 31.97 is NOT the elevation.
Fourth, how do you know that you were on Echo-8?? Were you able to scan in the GOL channels? Ie you may have been aimed at another of the ECHO sats, unless you scanned in transponders to see what channels were there, and any other of those sats would have been lower in the sky.
