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
course deviation indicator (IN-514R or IN-514B). The RT-308C Receiver-
Transmitter includes a 360-channel VHF communication receiver-trans-
mitter and a 160-channel VHF navigation receiver, both of which may be
operated simultaneously.
The communication receiver-t ransmitter receives and transmits sig-
nals between 118.00 and 135.9 5 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 circuits required to actuate the
course deviation needle. 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 (A TIS), 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 a r e in-
cluded in the course deviation indicator. T he communication receiver-
transmitter and the navigation receiver are synthesizer-controlled and
are tuned automatically when the frequency is selected. In addit ion, when
two or more radios are installed, a t ransmitter selector switch and a
speaker-phone selector switch are provided. Each control function is
described in Figure 1.
