Hi
Doppler shift depends on where you are (on earth) relative to the satellite.
A radio cannot know this, also not a TS2000.
This is what software like satpc32 is used for.
What a TS2000 and some other radios can do is apply a fixed ratio between uplink and downlink of a transponder. Excluding doppler. 
Btw also excluding eg a freq shift (drift) during a pass like AO73 has. That is something also satpc32 cannot compensate for.
Enjoy the challenge!

<I thought the TS-2000 had all the doppler correction built in. Why aren't you using that since your laptop isn't attached to the radio????
