Neat. This is something I have yet to do. The only settings that you can be sure of are around 222 az and 34 elevation. You could always use the twist and shout method: hook the reciever up to the dish, go to the point dish screen and find the correct satellite, then have a buddy watching the screen while you tweek the dish. For lack of a buddy you could call your cell from your home phone and just set it next to the tv, and take the cell outside with ya. It will take a few seconds for the receiver to adjust to your settings, so it could be slow going, and I hope you have the proper LNB for your receiver.
Does that dish have a skew setting? how big is the dish?
