Well I'm not sure? But, on my Pansat, when I'm going from sat to sat looking for hockey feeds (mostly), and one at a time. When I park on a sat, if I don't enter "Antenna Setup" before I go to the blind scan (Smart Search), it will go back to the previous sat and scan it. I usually don't catch it until the scan is over (I don't do this often, but it happens), at which point I'm ready to kick myself. Most receivers (I think), when you're 1st setting it up and programming the sats in, will move to the sat and then start a search. The Coolsat (old firmware/software) would start searching before you get to the sat, causing you to miss the first part of the scan. That's why I go to the sat and then start a search, of course all my sats are programmed, so there's no new sats involved. I think that has been fixed though? I know nothing about the Mercury II (or Fortec), but it sounds like it did something simular to my Pansat, and you were probably on AMC6 and went to AMC5 and started the scan and it went back to AMC6 and did the scan, while you thought you were on AMC5? Or maybe you were on AMC6 and your mind told you, you are on AMC5? Or maybe you just looked at it wrong, while being in a hurry?
