Edit your USALS longitude coordinate by a small increment in either direction. I change mine in 0.1 or 0.2 degree increments at a time. If signal quality increases on your reference satellite as you edit this value, then keep changing it in the same direction. If signal quality decreases, increment the value in the opposite direction. When you find the peak signal quality, you're done.

Right now, I have my USALS longitude value set 0.9 degrees off the "corrrect" longitude value. Doing this is a lot simpler than trying to tweak the dish so you can enter your exactly correct longitude value.
