Can someone help with the issue of finding true south? My Longitude is -1.678 degrees. Would that mean to find true south I would use the nearest satellite (Thor 1 degree west). Set my Diseqc motor to 0 (Zero) and point it at Thor. As I have set the Elevation/Lattitude on the motor would I then only have to set the declination on the dish until I got the strongest signal on Thor. Lastly would the .678 degrees lost make much of a difference in signal strength across the arc?
