REPEATER AND DUPLEX OPERATIONS

■ Duplex operation

D Setting the frequency offset
q Push [FUNC](M), and then push [SET](8) to enter
the Set mode.
w Push [Y] or [Z] to select the frequency offset item.
• "±" and decimal point "." blink, and the current frequency
offset appears.
e Rotate [VOL] to set the desired frequency offset.
• The offset is set in the same step as the frequency tuning step.
• The unit of the frequency offset is "MHz."
r Push [# ENT] to exit the Set mode.
D Setting the duplex direction
➥ Push [FUNC](M), and then push [DUP](4) to select
the offset direction.
• The "–" (negative offset) or "+" (positive offset) icon ap-
pears to represent the frequency offset direction.
• "–" or "+" blinks when the Reversed Duplex function is ON.
For only USA version of IC-V80:
The Auto Repeater function has priority over the manual
duplex setting. If the transmit frequency changes after set-
ting, the Auto Repeater function may have changed the
duplex setting. Turn OFF the Auto Repeater function to
prevent this.
D Reversed Duplex function
When the Reversed Duplex function is ON, the receive
and transmit frequencies are reversed.
q Push [FUNC](M), and then push [SET](8) to enter the Set
mode.
w Push [Y] or [Z] to select the Reversed Duplex func-
tion item (REV).
e Rotate [VOL] to turn the function ON or OFF.
r Push [# ENT] to exit the Set mode.
• "–" or "+" blinks when the Reversed Duplex function is
ON.
Each receive and transmit frequency is shown in the
table below, with the following confi gurations:
Input frequency : 145.300 MHz
Direction : – (negative)
Offset : 0.6 MHz
Reversed RX frequency
OFF 145.300 MHz
ON 144.700 MHz
TX frequency
144.700 MHz
145.300 MHz

• The "Offset" item in the Set mode
(0.6 MHz offset is selected.)
• Setting the shift direction of the transmit frequency
Appears
• Example— When the frequency offset is 0.6 MHz
Duplex While receiving
+ (positive)
– (negative)
• "–" or "+" blinks when the Reversed Duplex function is ON.
