The Fortec dishes have an elevation red marking by the bolts you would tighhten to get elevation.
make sure the settings are right in the unit. Since the LNB is a Universal, make sure the settings are set for Univaersal and not standard
I dont have a Fortec, but the screen should say
Universal 1
9750/10600 for the LO frequency
make sure you are on the right transponder (the one I noted above) and aim the dish straight south. I'm in MN so G3 is almost south for me.
Put the elevation close to what Pete has above (I cant see what it is right now since I'm replying)
key word when you aim is S L O W L Y move the dish back and forth...if you aim it south, you shouldnt have to move it back and forth much..maybe a couple inches or so
If you get nothing, try to move the elevation up or down and retry. Once you get a blip then you know you're in the ballpark and can really fine tune it
