GENERAL
CESSNA 300 ADF
(TYPE R-546E)
The Cessna 300 ADF is a panel-mounted, digitally tuned automatic
direction finder. It is designed to provide continuous 1 kHz digital tuning
in the frequency range of 200 kHz to 1,699 kHz and eliminates the need for
mechanical band switching. The system is comprised of a receiver, a
bearing indicator, a loop antenna, and a sense antenna. Operating controls
and displays for the Cessna 300 ADF are shown and described in Figure
1.
The audio system used in conjunction with this radio for speaker-phone
selection is shown and described in Section
7
of this handbook.
The Cessna 300 ADF can be used for position plotting and homing
procedures, and for aural reception of amplitude-modulated (AM) signals.
With the function selector knob at ADF, the Cessna 300 ADF provides a
visual indication, on the bearing indicator, of the bearing to the transmit-
ting station relative to the nose of the airplane. This is done by combining
signals from the sense antenna with signals from the loop antenna.
With the function selector knob at REC, the Cessna 300 ADF uses only
the sense antenna and operates as a conventional low-frequency receiver.
The Cessna 300 ADF is designed to receiver transmission from the
following radio facilities: commercial broadcast stations, low-frequency
range stations, non-directional radio beacons, ILS compass locators.
