Since you have the Invacom QPH LNBF, you can use it to find some of the stronger DBS birds. For now, take all switches out of the equation. Run one cable from a circular (C) output of your LNBF to your receiver. It is very helpful to have the receiver and a small TV at the dish site. Try to hit the satellites at 110w and 119w. In your antenna setup, use L.O. 11250, 22k off, DiSEqC off, motor off. Flip through your transponders to be sure you are on a live one. After you find something, mark the post and move the dish to a linear FSS bird like G-10R at 123w. Connect an L output of the Invacom to the receiver. Use L.O. 10750, 22k off, DiSEqC off, motor off. Finding the Ku linear sats will be harder than the circular DBS ones, since they are weaker and require a more exact aim. Use very slow movements of the dish, 1/4 of an inch can make the difference between no signal and the highest signal.
