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.
