i have an old dish for dtv, and i wanted to see if i could pick up the dn satellites with a pansat. But when i scanned, it did not pick up anything for dn. Even when i scanned a dtv satellite, it still did not pick up anything. the reception was at 80% but no quality. Is there something i must do specifically to the dtv dish to pick up dn. Any input would be much appreciated. Thank You.
