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-

frequency set to the repeater’s offset frequency.
qSet the offset frequency and turn ON the quick split
function in initial set mode in advance (pgs. 79, 80).
