SECTION 1
GENERAL
The Cessna 300 Na v/Com (Type RT-528E-1), shown in Figure 1,
consists of a panel-mounted receiver-transmitter and a single- or dual-
pointer remote course indicator. The r eceiver-transmitters include a
360-channel VHF communication receiver-tranSmitter and a 200-channel
VHF navigation receiver .
The communication receiver-t ransmitter receives and transmits sig-
nals between 118.00 and 135. 95 MHz in 50 kHz steps. The navigation re-
ceiver receives and interprets VOR and localizer signals between 108.00
and 117.95 MHz in 50 kHz steps . The c ommunication receiver-transmitter
and the navigation receiver are synthesizer - controlled and are tuned aut o-
matically when the frequency is selected.
A DME receiver-transmitter or a glide slope receiver, or both, may
be interconnected with the Cess na 300 Nav/Com set for automatic selec-
tion of the associated DME or GS fr eque ncy. When a VOR frequency is
selected on the Nav/Com, t he associated VORTAC or VOR-DME st ation
frequency will also be selected automatically; likewise, if a l ocalizer fre-
quency is selected, the associated glide slope frequency will be s elected
automatically.
All controls of the Cessna 300 Nav /Com, except t he omni bearing
selector knob (OBS), which is located on the cours e indicat or , a r e mount -
ed on the front panel of the receiver-transmitter . The course indicator
includes either a Single pointer and related OF F flag for VOR/LOC indi-
cation only, or dual pointers and related OFF fla gs for both VOR/LOC
and glide slope indications. The course indicator als o inc orpor at es a
back-course lamp (BC) which lights when back-cour se operation is select-
ed. In addition, when two or more radios a re installed, a t ransmitter
selector switch and a speaker-phone selector switch a r e provided. Each
control function is described in Figure 1.
