Selecting the ADF Receiver Mode
The following modes can be selected:
• ANT (antenna) – The ADF bearing pointer is
deflected on the HSI by approximately 90 degrees
relative to the aircraft heading. In this mode, the
NDB Morse code identifier can only be heard if the
ADF key is selected on the audio panel.
• ADF – The ADF bearing pointer moves to point in
the direction of the NDB station. In this mode, the
NDB Morse code identifier can only be heard if the
ADF key is selected on the audio panel.
• BFO (Beat Frequency Oscillator) – Provides an
audible tone when a frequency is tuned. This mode
allows for the audio identification of the interrupted
carrier beacon stations that are used in various parts
of the world. In this mode, the NDB Morse code
identifier can only be heard if the ADF key is selected
on the audio panel.
