The folks using the HTs are using the AO-51 satellite which is a much more conventional bird that is strickly VHF-FM up link and UHF-FM downlink. It is also a much easier to access bird in that the doppler shift is much easier to follow. There are several websites that discuss how to use a HT to get into AO-51.
The AO-16 satellite was until recently, a digipeater for data transmissions only. It ran into some software problems that almost spelled it's demise. They, the AO-16 team, found a way to use it in he very unconventional way of VHF-FM uplink and UHF-SSB downlink. It was a very clever work-around that saved the satellite. It does require a more advanced rig then a HT and really requires you to spin the VFO to keep track of the doppler shift but it is fun.
I'm sorry if I confused you but there are two fairly easy to use straight FM satellites, AO-51 and SO-50. AO-16 is an interesting work-around configuration that tests ones ability to "follow the doppler".
If I can be of any further help, just let me know..
