I’ve received 9k6 signals in 40 seconds intervals on 437.250 following 58921 but was unable to decode it.
One good example:
2025-03-13T10:23:37 437.250 9k6 FM.wav.zip (17.2 KB)
(Just remove the suffix .zip)
Please try for yourself.
Could it be NExSat-1, or maybe DRO-L?

Created some obs to save IQ recordings, lets see if we can decode them.
It is possible this is BPSK and not FSK

I also recorded it in USB, but looking at the wave form of the FM recording, it looks like FSK.
With a preamble at the beginning.
