SEcTION 1 - GENERAL
The Bendix/King Digital 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 1799 kHz and eliminates the need for
mechanical band switching. The system is comprised of a receiver, a built-in
electronic timer, a bearing indicator and a KA-44B combined loop and sense
antenna.
The Bendix/King Digital ADF can be used for position plotting and homing
procedures, and for aural reception of amplitude modulated (AM) signals.
The "flip-flop" frequency display allows switching between pre-selected
"STANDBY" and "ACTIVE" frequencies by pressing the frequency transfer
button. Both preselected frequencies are stored in a non-volatile memory circuit
(no battery power required) and displayed in self-dimming gas discharge
numerics. The active frequency is continuously displayed in the left window,
while the right window will display either the standby frequency or the selected
readout from the built-in timer.
The built-in electronic timer has two separate and independent timing
functions: (1) An automatic flight timer that starts whenever the unit is turned
on. This timer functions up to 59 hours and 59 minutes. (2) An elapsed timer
which will count up or down for up to 59 minutes and 59 seconds. When a
preset time interval has been programmed and the countdown reaches :00, the
display will flash for 15 seconds. Since both the flight timer and elapsed timer
operate independently, it is possible to monitor either one without disrupting
the other. The pushbutton controls and the bearing indicator are internally
lighted.
