Duplex operation
Duplex communication uses one frequency for transmit, and
a different frequency for receive. Generally, duplex is used in
communication through a repeater, some utility communica-
tions, 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. 68)

Set the receive frequency (repeater output frequency).
