SUPPLEMENT
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, consists 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 signals between 118.00 and 135.95
MHz in 50 kHz steps. The navigation receiver 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 select 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 included 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.
