■ Duplex operation
Duplex communication uses 2 different frequencies for trans-
mitting and receiving. Generally, duplex is used in communi-
cation through a repeater, some utility communications, 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. 16)
DD
Setting
qSet the receive station frequency (repeater output frequency).
wPush [TS•SET] for 1 sec. to enter set mode.
eRotate [DIAL] to select “EXPAND.”
•“EXPAND” disappears after 1 sec. and “OFF” (default) and “EX”
appear.
rWhile pushing [FUNC], rotate [DIAL] to select “ON.”
tRotate [DIAL] to select “OFFSET.”
•“OFFSET” disappears after 1 sec. and “0.000” (default) and
“OW” appear.
yWhile pushing [FUNC], rotate [DIAL] to set the desired off-
set frequency within 0.000–159.995 MHz range.
• The tuning step, selected in VFO mode, is used for setting.
uRotate [DIAL] to select “DUP.”
•“DUP” disappears after 1 sec. and “OFF” (default) and “DP” ap-
pear.
iWhile pushing [FUNC], rotate [DIAL] to select “–DUP” or
“+DUP.”
oPush [TS•SET] to exit set mode.
!0Push and hold [SQL] to monitor the transmit station fre-
quency
(repeater input frequency) directly.
