CESSNA 300 NAV/COM
(COM/VOR, No LOC - Type RT-308C)
SECTION 1
GENERAL
The Cessna 300 Nav/Com (Type RT-308C), shown in Figure 1, con-
sists of a panel-mounted receiver-transmitter (RT-308C) and a single
needle course deviation indicator (IN-514R or IN-514B). The RT-308C
Receiver-Transmitter includes a 360-channel VHF communication receiver-
transmitter and a 160-channel VHF navigation receiver, both of which may
be operated simultaneously.
The communication receiver-transmitter receives and transmits sig-
nals between 118. 00 and 135. 95 MHz in 50 kHz steps. The navigation re-
ceiver receives and interprets VHF omnidirectional range (VOR) signals
between 108. 00 and 117. 95 MHz. Although localizer signals (all odd-
tenth frequencies between 108. 1 and 111. 9 MHz) can also be received, the
navigation receiver does not include the necessary circuits to interpret
the signals for localizer indications. However, the audio portion of the
localizer is audible so that flight information, such as that broadcast in
certain areas on selected localizer frequencies by the Automatic Terminal
Information Service (ATIS), may be heard.
All controls for the Cessna 300 Nav/Com (Type RT-308C), except the
omni bearing selector (OBS), are mounted on the front panel of the receiver-
transmitter. The course selector and the navigation indicators are in-
cluded in the course deviation indicator. The communication receiver-
transmitter and the navigation receiver are synthesizer-controlled and
are tuned automatically when the frequency is selected. In addition, when
two or more radios are installed, a transmitter selector switch and a
speaker-phone selector switch are provided. Each control function is
described in Figure 1.
