Repeater operation
When using a repeater, the transmit frequency is shifted from
the receive frequency by the frequency offset (p. 22). This is
called duplex operation. It is convenient to program repeater
information into memory channels (p. 26).
q
Set the receive frequency (the repeater output frequency).
w
Push
[FUNC](
M
), and then
[DUP]
(4)
one or more times to
set the shift direction of the transmit frequency. ( “–” or “+”;
see page 22 for details.)
e
If desired, push
[FUNC](
M
) and then
[TONE]
(1)
one or
more times to activate the subaudible tone encoder.
• “
” appears.
• Select the desired subaudible
tone frequency. (p. 23)
r
Hold down
[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. 22).
t
Release
[PTT] to receive.
y
Hold down
[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)
