RFCS RECEIVE SYSTEM
The RFCS receive system shown in figure 2-19 is
used to receive the transmitted signal and convert it
back to a usable tty output.
Antenna Filter
The antenna filter receives the rf signal from the
antenna and filters out any unwanted signals so only
the proper band of frequencies are passed on to the
receiver.
Radio Receiver
The receiver translates the rf signal to an audio
signal.
Receiver Transfer Switchboard
The switchboard is used to connect the receiver to
any one of the convertors in the convertor group.
Convertor/Comparator Group
The convertor/comparator group is used with
receivers in either space diversity or frequency
diversity operation to convert the frequency shift af
signal from the receiver into dc pulses that open and
close the dc loop according to the mark and space
characters received. When the system is not using
diversity operation, each convertor can be used with a
separate receiver.
