1. ANT/ADF MODE ANNUNCIATOR - Antenna (ANT) is selected
when the ADF button is in the OUT position. This mode improves
the audio reception and is usually used for station identification.
The bearing pointer is deactivated and will park in the 90° relative
position. Automatic Direction Finder (ADF) mode is selected by
pushing the ADF button. This mode activates the bearing pointer
and will point in the direction of the station relative to the aircraft
heading.
2. ACTIVE FREQUENCY DISPLAY - The frequency to which the
ADF is tuned is displayed here. The active ADF frequency can be
changed directly when either of the timer functions is selected.
3. BFO (Beat Frequency Oscillator) ANNUNCIATOR - The BFO
mode is activated and annunciated by pushing the BFO button.
When BFO mode is active, the carrier wave and its morse code
identifier can be heard.
CW signals (Morse Code) are unmodulated and no audio
will be heard without use of BFO. This type of signal is not
used in the United States air navigation. It is used in some
foreign countries and marine beacons.
4. STANDBY FREQUENCY/FLIGHT TIME OR ELAPSED TIME
DISPLAY - When FRQ is shown, the STANDBY frequency is
shown in the right display. The STANDBY frequency is selected
using the frequency select knobs. The selected STANDBY
frequency is put into the active frequency window by pushing the
frequency transfer button. Either the standby frequency, the flight
timer, or the elapsed time is shown in this position. The flight
timer and elapsed timer replace the standby frequency which
goes into blind memory to be called back at any time by pushing
the FRQ button (item 10). Flight time or elapsed time are shown
and annunciated by depressing the FLT/ET button.
5. FLIGHT TIMER AND ELAPSED TIMER MODE ANNUNCIATION
- Either the elapsed time (ET) or flight time (FLT) mode is
annunciated here.
