1KUNS-PF changing modulation?

I made this recording of the same pass this morning 2018-07-06 appr. 0800UT, it seems 1KUNS-PF changes from GMSK1200 to something else, same happened yesterday. UZ7HO’s soundmodem decodes easily the GMSK1200 frames but not the other frames, whats going on?

They are probably experimenting with higher bitrates.
