DUPLEX OPERATION

Duplex operation allows the radio to transmit on a different
frequency to that which it receives allowing operation through
repeater stations. Repeaters automatically
re-transmit your signal over a wider area, providing greatly
increased range.
Duplex operates only on channels 1-8 and 41-48. When
duplex is selected on these channels, the radio receives on
that channel but actually transmits 30 channels higher.
