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.
q Set the receive frequency (repeater output frequency).
w Push
[A•

and
[4•
DUP
]
several times to select “–” or “+.”
• “–” indicates the transmit frequency is shifted down; “+” indicates
the transmit frequency is shifted up.
• Blinking “–” or “+” indicates the reversed duplex mode is selected
in
SET MODE
(p. 58).

• “ ” appears.
• Select the desired subaudible tone frequency, if necessary.
(p. 18)
r Push and hold

to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If “OFF” appears, check the offset frequency (see next page for
details) and direction.
t Release

to receive.
y Push and hold
[MONI]
to check whether the other station’s
transmit signal can be directly received.

Reversed duplex mode
When the reversed duplex mode is selected, the receive fre-
quency shifts.
(Transmit frequency shifts in normal duplex mode.)
Each receive and transmit frequency is shown in the table
below with the following conditions;
IC-V82
Input frequency
: 145.30 MHz
Direction
: – (negative)
Offset frequency
: 0.6 MHz
IC-U82
Input frequency
: 439.80 MHz
Direction
: – (negative)
Offset frequency
: 5 MHz
