RECEIVE AND TRANSMIT
Repeater operation
A repeater amplifies received signals and retransmits
them on a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre-
quency by an offset amount. A repeater can be ac-
cessed using split frequency operation with the shift
frequency set to the repeater’s frequency offset.
To access a repeater that requires a repeater tone,
set the repeater tone frequency in the Tone frequen-
cy screen. (p. 5-38)
