The transponders on 97W ku are well defined and have high Symbol Rates. This ku satellite is easy to scan, but how good is the Alien2 on satellites with transponder that have low symbol rates?

The Raptor is looking for transponders with a SR 999 and up. This takes extra time when compared to a receiver that is looking for transponders with a SR of 1500 or 2000 and up. I doubt the Alien2 is looking for low SR transponders right now because I could not get the Alien1 to lock on low symbol rate transponders.

There have not been any real advances in satellite blind scan technology for a while. Right now, faster blind scan speeds usually result in missed channels or transponders. I expect some advances to be made in satellite blind scan, but it will probably be late in 2013 or 2014 before we see them.
