Identity channel
VOR signals often carry a morse coded tone to identify the transmitter. This signal can be
simulated by selecting the
[Ident/Comms]
key to produce a display similar to the one shown in
Fig. A-16.

The instrument will generate a VOR signal having equal sub-carrier and 30 Hz tone depths with a
0° bearing. The AM depth displayed is the depth of each tone and can be changed using the
[VOR]
key.
An additional AM signal, AM2, can be added to this waveform. The source of this modulation
can be selected using the
[Select Source]
key and if internal modulation has been selected the
modulation frequency can be set using the
[Source Freq.]
key. The depth of this additional signal
can be set by the
[AM2 Depth]
key.
ADF mode
The ADF mode is selected using the
[ADF]
key on the
Avionics Mode Selection Menu
shown in
Fig. A-3. This menu can be selected from other aviation modes (VOR, ILS, MARKER BEACON,
SEL-CAL) using the
[Avionics Modes]
key. Selecting the ADF mode and pressing the [SIG
GEN] key produces the display shown in Fig. A-17.
