You are set on NDB signal frequency?
Need assign key for "Primary Navigation Frequency" (NDB) and tune in frequency used (perhaps have this info in mission briefing).
Long Range Antenna frequency for default are 300 MHZ (is adjustable from 200 up to 600).
This instrument on upper/left side of panel (left of speedometer) should indicate if you are flying over the beam.
I dont know how Destastersoft use this system, but imagine a script to tell you when drop the bombs - you if are over the NDB signal - since in CloD dev's forget to model the Morse Code need for Knickebein (and Lorenz) work properly.
