there are 2 scales on the
HH90 motor (either side)
did you set the side that as "LAT" on it to 40.1 (your latitude setting)?
38.8 is right for the dish elevation, according to my calculations.
You should:
set the settings on motor LAT side scale to 40.1
set the dish to 38.8
set the motor at "reference" or zero
make sure your LNB is straight up and down (now skew) and is pulled as far away from the dish in the holder as possible.
put in your LAT & LONG in the receiver's USALS settings
Point the whole thing while motor is at zero to about 191 degrees on a good compass.
Select AMC5 as your south satellite, and have the motor drive there. It should not move much.
Make sure you are on 11720 for Utah Education network trasponder.
Try to get a signal by adjusting the whole contraption on the pole, and by adjusting dish elevation. You might have to move your dish elevation up +5 as has been reported here, but that should put you on the arc.
Even though you are "off the arc", when you did hit KUIL should come in at 80 or 90. It is a very strong signal. But, I must mention that some receivers signal indicators are quite stingy, so 58% isnt surprizing, but would seem a bit low to me.
look at these directions, number 5 left hand picture is how it should be for 40.1
also notice bolt mouting holes are different between left and right pic.
