For those using DGUI hardcore gui, to send correct convoy heading (if you don't know):
- 1) unlock tdc with button (must be blue)
- 2) now this dial can turn...select correct convoy heading
- 3) ask your radio guy to send contact report (with still tdc unlock!)
- 4) after, don't forget to re-lock your tdc with button!
- 5) you can verify your message sent with the heading you gave
Telling this because i figured out the good dial to turn not long ago!
