Sorry. I got some more info from the swedish tv-channel TV4. A message was sent on a emergency frequency used by the russian navy to call an emergency. It was responded by a frequency sent form the russian naval base in Kaliningrad. The later frequency was not decoded by the swedish forces but they knew where it cane from.
That good report
Maybe Vlady don’t understand Swede vant be alone like Greta Garbo okay my bad LOL!
