I got around a 60% signal on 83W using an old 74cm Primestar dish, I was unable to get a clear picture. I'm wanting the retro tv channel. I figured that dish must not have enough gain so I tried aiming my old 1.2m Hughes dish at 83W and did a blind scan. I'm getting signal but nothing comes up in channel list. I'm using a Coolsat 7000. Any suggestions?
