BASIC OPERATION

Duplex communication uses 2 different frequencies for trans-
mitting and receiving. Generally, duplex is used in communi-
cation through a repeater, some utility communications, etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the offset fre-
quency. Repeater information (offset frequency and shift di-
rection) can be programmed into memory channels. (p. 16)
