Mystery Signal on 6974.4 CW (Update: Probably M51)

Mystery CW TX has been going on for some time this afternoon (Local) on 6974.4. It sounds like random numbers/letters and some punctuation. Maybe in a style like FFG (Five Figure Groups). Reported to be not heard in Germany. Heard well in North America. kiwiSDR network TDoA suggests South West UK as origin. See image.
