RECEIVE AND TRANSMIT
■ Repeater operation
A repeater amplifies received signals and re-transmits
them at a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre-
quency by an offset frequency. A repeater can be ac-
cessed using split frequency operation with the shift
frequency set to the repeater’s offset frequency.
