From this post ISS Deployment (JAXA) J-SSOD#35 - 2026-02-03 08:20 UTC - #20 by K4KDR and the info above I’ve changed the FM to MSK9k6 AX.100.
As Jan noted, trying to find information for launches/deployments, especially those with many satellites is sometimes a difficult process. While everyone tries their best, there can be partial or no information.
This is why we started and keep SatNOGS DB a crowd-sourced project and anyone can suggest changes for satellites and transmitters by providing citation/sources for the changes.
One last note, the FM mode is now used as a default value but this soon will change in the next releases to something that will show that there is no info for the modulation.
