BASIC OPERATION 4 ■ Duplex operation Duplex communication uses two different frequencies for transmitting and receiving.

BASIC OPERATION
4
Duplex communication uses two different frequencies for
transmitting and receiving. Generally, duplex is used in com-
munication through a repeater, some utility communications,
etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the frequency
offset. Repeater information (frequency offset and shift di-
rection) can be programmed into memory channels. (p. 19)
