SECTION 1
GENERAL
The Bendix/King KX 155A VHF Nav/Comm, shown in Figure 1,
consists of a panel-mounted receiver-transmitter and a KI 208 or KI
209A Indicator. .
The sel includes a' 760-channel VHF communications receiver-
transmitter and a 200-channel VHF. navigation receiver. A 40-
channel glide- slope receiver is also included if the KI 209A
indicator is used. The communications receiver-transmitter receives
and transmits signals between 118.00 and 136.975 MHz with 25-
kHz spacing. Optional 8.33 kHz (2280 channel) Comm is available.
The navigation receiver "receives VOR and localizer .signals between
108.00 and 117.95 MHz in 50-kHz steps. The glide slope"receiver
is automatically tuned when a localizer frequency is selected. The
circuits required to interpret the VOR-and localizer signals are also
an integral part of the' Nav receiver.
Large self-dimming gas discharge readouts display both .the
communications and navigation operating frequencies. The KX-
155A's "flip-flop" preselect feature enables you to store one
frequency in the standby display while operating on another and
then interchange them instantly with the touch of a button. Both the
active (COMM) and the standby (STBY) frequencies may be
displayed at all times and are stored in nonvolatile memory without
drain on the aircraft battery. KX 155A has 32 programmable comm
channels, a stuck microphone alert and transmitter shutdown,
Bearing To/From radial mode, course deviation indicator mode and
