General
When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency. It is convenient
to program repeater information into memory channels.

About reversed duplex mode
When the reversed duplex mode is selected, the receive fre-

Offset frequency
When communicating through a repeater, the transmit fre-
quency is shifted from the receive frequency by an amount
determined by the offset frequency.
