21. Huff-Duff (High Frequency DF)
Whenever the radio is used, there should be a % risk per character sent, of escorts getting a bearing of the transmitting u-boat. After a short interval, (where the escorts would share the frequency being used by the u-boat and it's approximate DF bearing) any further transmissions would have a higher % per character of being detected. If a second DF bearing is gained by the escorts, a tribal or Bittern is sent at full-speed to that fixed position, and there executes an asdic search, and opens fire if the u-boat is on the surface. If the escort makes no contact at the DF'd position, it returns at full-speed to the convoy. Not more than two escorts at a time would be detached.
Not sure when "Huff-Duff" was implemented? I hope eventually that the game will model the technical progress for both u-boats and escorts, and the counter-measures of each....
