Not only do you have to radio in a status report but you must do it within a certain distance of where you completed your mission. I got the "insert spy in Dalian" mission several times in a row, right after I posted that I never got repeat missions.
"WTF!!!" said I, meaning "Why that's funny" of course. Then I read that when you sight enemy ships, to get a reply you have to call in within sight of the ships.
I thought "The life raft is a ship." When I launch it I might have to phone home while I'm in sight of it. I did and the repeat missions stopped. I received immediate confirmation and a new mission. As a bonus, you might be attacked by more of those Betties you like so much.
