■ Duplex operation
Duplex communication uses one frequency for transmit, and
a different frequency for receive. Generally, duplex is used in
communication through a repeater, some utility communica-
tions, etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the offset fre-
quency. Repeater information (offset frequency and shift di-
rection) can be programmed into memory channels. (p. 68)
qSet the receive frequency (repeater output frequency).
(p. 48)
wRight click zDUPx to display the [DUP Offset] screen.
eSet the desired offset frequency within 0.000000–
1000.000000 MHz range, then click the close button ([X])
to close the setting screen.
rLeft click zDUPx to toggle the duplex direction from OFF
(simplex), DUP– or DUP+.
• “ ” or “ ” appears when the duplex direction is
set.
tClick zMONIx to monitor the transmit station frequency (re-
peater input frequency).
The displayed frequency shifts the offset frequency when
monitor function is in use.
