REPEATER AND DUPLEX OPERATIONS
11-4
Duplex operation
The duplex operation shifts the transmit frequency
up or down from the receive frequency by an offset
amount.
DSetting the frequency offset
NOTE: The frequency offset cannot be changed
when using the DR function.
[MENU] > SET > DUP/TONE... > Offset Freq
1. Push [MENU].
2. Select “DUP/TONE...” in the “SET” menu.
3. Select “Offset Freq.”
4. Rotate [DIAL] to set the offset.
L Information
• Set to between 0.000.00 and 59.99500 MHz.
• The selected tuning step in the VFO mode is used to
set the offset.
• To exit the MENU screen, push [MENU].
TIP: If the offset value causes the transmit frequency
to be out of the band, “OFF BAND” is displayed
when you push [PTT], and transmit will be inhibited.
(p. 11-5)
DSetting the duplex direction
1. Push [QUICK].
2. Select “DUP.”
3. Select the duplex direction.
• OFF: For simplex operation (the receive and
transmit frequencies are the same).
• DUP–: The transmit frequency shifts down from the
receive frequency by the offset amount.
• DUP+: The transmit frequency shifts up from the
receive frequency by the offset amount.
• Displays “D–” or “D+.”
DDuplex operation
1. Hold down [SQL] to listen to the transmit
frequency to check whether another station is
transmitting on it, or not.
• The shifted transmit frequency is displayed.
2. Operate in a normal way.
L In the same way as a simplex call, alternately
transmit and receive.
NOTE: When the Auto Repeater function is ON, and
the operating frequency is set out of the repeater
output frequency range, the Duplex mode is
automatically canceled.
