BASIC 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. 26)

D

D Setting

q Set the receive station frequency 

(repeater output frequency)

.

w Push [8 SET] for 1 sec. to enter set mode.
e Rotate [R-DIAL] to select “SET EXPAND” item, then push

[8 SET].

r Rotate [R-DIAL] to select “ON.”
t Rotate [R-DIAL] to select “OFFSET FREQ,” then push

[8 SET].

y Rotate [R-DIAL] to set the desired offset frequency within

0.00000–159.99999 MHz range, then push [8 SET].

• The tuning step, selected in VFO mode, is used for setting.
• Push [VFO MHz] for 1 sec. then rotate [R-DIAL] to change the

frequency in 1 MHz steps, or push for 1 sec. again then rotate
[R-DIAL] to change the frequency in 10 MHz steps. (Each push
for 1 sec. toggles 1 MHz or 10 MHz tuning steps.)

u Rotate [R-DIAL] to select “DUPLEX.”

i Rotate [R-DIAL] to select “–DUP” or “+DUP.”
o Push [DUALWATCH] to exit set mode.
!0 Push and hold [SQL] to monitor the transmit station fre-

quency 

(repeater input frequency)
