 Mode A (2 meter up/10 meter down) makes a very nice mode for newcomers and 
 others wishing to utilize existing equipment and antennas to work the 
 birds.  Doppler shift on either band is not severe.  Using standard

Additionally, 2 meters up reduces terrestrial interference from "innocent" 
operators not aware of the sat uplink frequencies or from "skip" type 
operations not under the footprint...
