REPEATER OPERATION

5
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).

several times to activate the
subaudible tone encoder, if required.
• “ ” appears.
• Select the desired subaudible tone frequency, if necessary. 
(p. 18)
r Push and hold 
[PTT]
to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If “OFF” appears, check the offset frequency (see right content
for details) and direction.
t Release 
[PTT]
to receive.
y Push and hold 
[MONI]
to check whether the other station’s
transmit signal can be directly received or not.
About 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 freq.-145.30 MHz, Direction-negative, Offset frequency-0.6 MHz
IC-U82: Input freq.-439.80 MHz, Direction-negative, Offset frequency-5 MHz
Offset frequency
When communicating through a repeater, the transmit fre-
quency is shifted from the receive frequency by an amount
determined by the offset frequency.

several times until “±” and offset frequency

• Selectable steps are the same as the pre-set tuning steps.
• The unit of the displayed offset frequency is “MHz.”
