Matias,

There is a forked version of Gpredict that claims to have solved the IC 910/9100/9700 doppler correction issue. I believe the fork is located here:

https://github.com/arodland/gpredict/tree/ic-910-hack

I have not tried this fork, as I don't own any of the above transceivers, so I cannot comment on it's effectiveness. Some discussion of the issue can be found in the Libre Space forums here:

https://community.libre.space/t/icom-ic9700-doppler-control/4818

Good luck, and please let us know how you proceed. Part of my hesitation to buy a 9700 is this issue, as I only have Linux computers at home (besides an old ipad and my wifes Surface Pro).
