I have a 30 inch hotdish and a sg2100 motor and running nexus-s a ku lnb. I have set the dish to the furthest west sat I could get a signal at using my channel master sig meter. I went and turned on progdvb and went to scan transponders. I went through the entire region of sats in the transponder section after I updated all the North American ones but I can't get a signal on any of them
