REPEATER AND DUPLEX OPERATIONS

■ FM Repeater operation

A repeater receives transmitted signals and retrans-
mits them on a different frequency. The transmit fre-
quency is shifted from the receive frequency by a pre-
set frequency offset.
In duplex operation, the transceiver's frequency offset
is set to the same as that of the repeater. (p. 10-12)
