The following modes can be selected: (In all modes NDB audio can be heard by pressing the
ADF
Key on
the Audio Panel.)
• ANT (Antenna) – The ADF bearing pointer parks on the HSI at 90 degrees. Best mode for listening to NDB
audio.

• ADF/BFO (ADF/Beat Frequency Oscillator) – The ADF pointer points to the relative bearing of the NDB
station and an audible tone confirms signal reception. This mode allows identification of the interrupted
carrier beacon stations used in various parts of the world.
• ANT/BFO (Antenna/Beat Frequency Oscillator) – The ADF bearing pointer parks on the HSI at 90 degrees
