FOR SIMULATION PURPOSES ONLY
There are 2 rows of audio source selection buttons each with an integral
green light that illuminates on receiver selection. Normally, selection of a
transmitter will automatically connect the appropriate receiver to the
headphones. If necessary this can be followed up by pushing one of the
audio buttons. Generally the buttons are used for selecting additional audio
information, for example when identifying a navigation aid.
Pushing a button selects the audio source, pushing it again deselects it. Of
the 10 selectable sources, COM 3, ADF, and AUX are unavailable. MONI will
play back random radio chatter.
Bendix/King KTR 909 UHF Radio
The KTR 909 UHF transceiver provides two-way voice communications over
the frequency range available in the simulation.
Manual frequency selection is achieved using the concentric, rotary controls
on the right of the unit; the outer knob controls the frequency in 1 MHz steps,
the inner controls the frequency in 25 KHz steps.
In both cases, clockwise rotation of the knobs increases the frequency. A
wrap-around feature means the unit will roll to the other end of the frequency
range as the controls are rotated.
