I have a dish pointing 119 and 110 and another one pointing 61.5 ... 119 and 110 when scanned everything seems to be working fine. 61.5 is on a single LNB and is giving about 75 strength signals but when i auto scan it catches only about 20 channels and when I blind scan it most of the channels don't work and show Searching Signal .. any advices suggestions ? please it will be great thank u
