 Modes
 -----
 
+Sync mode:
 When internal time < 10 minutes, transmit only sign without "MO", in short timeslots, then stay silent 30s.
 
+Normal mode:
 If internal time >= 10 minutes, transmit "MO<sign>" for a full minute timeslot.
 
+Permanent mode:
+At startup and before sync, all foxes start in permanent mode.
