Ok if you are in AZ I would probably be hunting for 123 for
C Band. I would also start by taking the jumper off and running from Ku only. Locate the sat that way. If memory server me correct 0 for that lnbf is somewhere around the flat portion at 4 o'clock as you are looking at the face of teh dish. If you go to
Sadoun Satellite Sales ( 1-888-519-9595 ) there is a very good area devoted to stationary installs. There you should be able to calculate your skew angle. Simply rotate the lnbf in the direction stated rounghly the correct degrees stated.
Now at least you should be close enough to find the sat. Do not adjust skew again until you locate the sat. You are probably not going to find 123 (G10R) you are most likely going to find 121 first which is an Echo bird. It is much stronger that G10R. You need to be set on an active transponder. Once you locate a sat scan it in and compare stations with
LyngSat - Lyngemark Satellite to find out where you are.
Patience is the key along with slow movement. You also need to have a tv and the receiver out at the dish. Once you lock G10R (123) now peak your dish. East to west and then with dish elevation and finally go back to the skew to get your peak signal. At this point you can replace the jumper and setup your receiver for both C and Ku from the lnbf. See if you can get any C Band now. C Band will be far more difficult to find with a 1.8m dish than Ku will be.
