South Korean SWLer Moomin posted this to his youtube channel a few days ago wondering what it was. The closest I could come up with, is that this frequency was listed in N&O newsletter # 200 as a frequency used by M32a, a Russian Navy station. The designation M32a would indicate a morse code station, but this obviously is not CW.
Anyway, your sleuthing is welcome and if you think you know what it is, please comment on the video itself as well as here. Moomin is interested in an English translation of what the Russian OM is saying, if anyone reading this can speak the language.

QTH: Gyeonggi-do, Siheung-si, South Korea. I believe he uses SDRPlay and his antenna is a 303WA-2 MF/HF.
EDIT: It does sound a lot like 29B6 'Kontayner' OTH Radar per sididwiki. I'm not expert enough to call it, however.
EDIT 2: per quick discussion with Token on the pirate chat, it's a Russian OFDM modem.
