[SBE] sat finder

[A9xw at cs.com]

I've put in a lot of dishes. My cheap and dirty method is to set the 
elevation first, since that will intersect the sat arc in two places (unless at Zenith 
at your location) then rotate for signal, then peak with the receiver. Fine 
for fixed sat dishes, Vsats, etc. Skew is the inverse of the longitude between 
you and the sat. I always use cross pol to set skew since the null is a lot 
easier to see than the peak. Think of the arc at zenith, the sat, your longitude 
and the sat longitude as a rectangle.
