As a ham operator the thing I noticed was the missing identification from the party talking.. just 'Helge Ingstad, turn starboard'. And so on. Never a 'Helge Ingstad, this is Sola <"on course so-and-so, speed so-and-so"..'.
Helge Instad didn't (according to the report, and no wonder) understand who they were talking to. Not that the personnel on board Helge Ingstad were much better.
