That's how I did it Monday night. My fortec lifetime NA can just scan V or H.
I printed out the page on Langsat that list ALL the FTA for North America. Then I aimed in the general direction with a Satellite finder meter. Then blind scanned. I was receiving White Spring TV.
Since that is on IA7 looking on Langsat I saw that I needed to move 5 deg. left and 5 deg higher to aim at G10. The elevation adjustment screw worked good.
It took me about 20 min. from the time I found White Spring, to locate G10R, fine tune everything and lock it all down.
I still need to run coax into the house to my switch but on 11720 I am getting a quality of around 59.
Let us know how it goes.
