[sarex] need info on orbitron auto doppler shift

I hve been working the ISS for some time now. Manually tuning the up link and down link frequencies. I use orbitron and it works well for position. Has anyone interfaced orbitron to a TS-2000 so it automatically adjusts the doppler shift during the pass? If you have any information or a link you can send me i appreciate it. Does orbitron do this automatically or do i need to add some other software? Thanks, Tom W5KUB
