I caught this on my Perseus SDR recording in NW Germany
23.07 UTC TX on and carrier detected, no audio yet
23.13 UTC now some audio came up
23.14 UTC talk by OM, much talk lateron, conversation OM,YL
00.00 UTC TX off, carrier gone
I'm not sure if this was a pirate here, SINPO 13211
Maybe someone can help me out?!
