i have a pansat converted (2700) when i load the last bin 235, lost a llot of channels, like sport channels, some 300 and when i scan the sat 119 i can get only 91 channels....
if your getting low channels one your either on the wrong dn sat or its not a good time to scan do to the weather. best time to scan is on a nice clear day to get the most number of channels.
Also with that Pansat it is easier to delete the entire sat and rescan than it is to try to delete individual channels. If you do an all scan instead of a blind scan you won't get duplicate channels
