OPERATION
3-1-26
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. 3-1-22.

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.
