DopplerPSK is a great program for dealing with doppler shift on the 10 meter
uplink.  The point being made that Yes, all mode rigs can do very small
tuning steps in VFO mode as can my FT847.  If I were going to use that one
rig for NO-84, even with SatPC32, I would turn the doppler correction for
uplink "OFF" and only track the 435 downlink FM so I could hear the FM
carrier throughout,  but let doppler PSK adjust audio tone for doppler and
that will nicely keep the PSK signal stable AT the Satellite, inside the
28.120 + 3Khz receive passband.   The cool thing is that you can still use
just an FM mobile rig to receive the FM downlink, and 5Khz steps will still
work pretty much just fine.
