Repeater And Duplex Operation; Repeater Operation - Icom IC-V80 Instruction Manual

■ Repeater operation

When using a repeater, the transmit frequency is shifted
from the receive frequency by the frequency offset (p. 21).
This is called duplex operation. It is convenient to program
repeater information into memory channels (p. 25).
Repeater
144.700 MHz
145.300 MHz
Station A
q Set the receive frequency (the repeater output frequency).
w Push [FUNC](M), and then [DUP](4) several times to set
the shift direction of the transmit frequency. ( "–" or "+";
See page 21 for details.)
• When the auto repeater function is in use (U.S.A. version only),
this selection and step e are not necessary. (p. 23).
e If desired, push [FUNC](M) and then [TONE](1) several
times to activate the subaudible tone encoder.
• " " appears.
• Select the desired subaudible
tone frequency. (p. 22)

REPEATER AND DUPLEX OPERATION

Uplink
144.700 MHz
(transmit freq.)
Downlink
(receive freq.)
145.300 MHz
Station B
Appears
r Push and hold [PTT] to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If "OFF" appears, check the frequency offset and shift direction
(p. 21).
t Release [PTT] to receive.
While receiving
y Push and hold [MONI] to check whether the other station's
transmit signal can be directly received or not.
• When the other station's signal can be directly received, move
to a non-repeater frequency to use simplex. (duplex OFF)
For the U.S.A. version:
Auto repeater function uses standard values of the re-
peater tone frequency and frequency offset.
