Repeater and Duplex Mode
: Duplex operation allows the radio to transmit on
a different frequency to that which it receives. This allows operation through re-
peater stations.
A repeater station consists of a linked transmitter/receiver combination installed in
a prominent location.
The repeater is designed to receive signals on a designated channel and retransmit
them on another channel.
Repeater stations, usually located on mountaintops or other high locations, provide
a dramatic extension of the communication range for low-powered hand-held or
mobile transceivers.
Normally, UHF radios transmit and receive on the same frequency - known as
Simplex operation. However to communicate through repeaters, your radio must
be able to transmit and receive on different channels - otherwise known as Duplex
operation.
This radio can easily perform the repeater operation by selecting the operating
channel to the repeater channel by the [
q
]/[
p
] key.
The repeater channel is set in channels 1 - 8 and 41 - 48 which have been allocated
for repeater use. In the repeater channel, the “
D
”
notation is appeared on the right side of the channel
indication. Refer to page 26 for details of the Chan-
nel List.
