A repeater consists of a transmitter/receiver
system installed in a prominent location. The
repeater is designed to receive signals on a
designated channel and re-transmit them on
another channel.
Repeaters are usually located on hills,
mountains or tall buildings. The increased
elevation greatly improves the range of the
repeater beyond that of normal base or mobile
installations. This means that repeaters are able
to receive and re-transmit signals between
UHF CB stations that would otherwise be out of
range of each other.
Normally, UHF transceivers transmit and
receive on the same channel. This is known as
SIMPLEX. However, to communicate through
repeaters, your transceiver must be able to
transmit and receive on different channels
(known as DUPLEX). Your TX4200 is fitted with
a Duplex button to allow you to operate through
repeaters.
The Duplex function only operates on channels
1 to 8. When Duplex is selected your TX4200
receives on the selected channel (e.g. channel
1) but automatically transmits 30 channels
higher (i.e. channel 31). The UHF CB repeater
then receives your signal on channel 31 and
re-transmit it on channel 1 for others to hear.
