If you are looking for doppler control for the 9100, take a look at SatPC32. It is available at http://www.dk1tb.de/downloadeng.htm
As a demo, it is fully functional but you have to input your location every time the program starts. You can purchase the key for it through AMSAT http://www.amsat.org/amsat-new/ which will store all your settings. Support for it is outstanding via the AMSAT BB.
