Thank you IU for creating the page! We heard this on University of Twente's WebSDR yesterday at around 10 PM UTC. Here is another waterfall if desired.

Ignore the unrelated data modem to the right of it.

Just a note, the 8-MFSKMultiple Frequency Shift-Keying that was noticed I believe is 2G ALEAutomatic Link Establishment, used for link establishment, but it may be a variant of this waveform style. IIRC there is a signal on this site which also uses 8-MFSKMultiple Frequency Shift-Keying but is for data, not for link establishment.

EDIT: This is not 2G ALEAutomatic Link Establishment, the bandwidth is much wider, and speed may be different. Possible Russian experimental digimode? --Cartoonman (talk) 14:38, 21 August 2017 (NZST)

This video seems to be of the same thing, starting around 2 minutes in. Fiber (talk) 19:38, 25 October 2017 (NZDT)

Another update, is there a possibility that this turned out to be the somewhat newly discovered XPB? http://priyom.org/number-stations/digital/xpb Fiber (talk) 07:24, 8 May 2019 (NZST)
