1. ADVANCED OPERATIONS
Duplex operation
Data communication
The Duplex operation shifts the transmit frequency
up or down from the receive frequency by an offset
amount.
• 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.
1. Push
FUNCTION
.
2. Touch [
w
].
3. Touch [DUP].
• Each touch selects “DUP–,” “DUP+” or “OFF.”
4.
Touch [DUP] for 1 second.
5.
Enter the frequency offset, and then touch [ENT].
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 cancelled.

SSB-DATA, AM-DATA and FM-DATA modes
You can operate the data mode using AFSK (Audio
Frequency Shift Keying).
L
When operating PSK31, SSTV or JT65B with a PC
application software, refer to the software’s instruction
manual.
1.
Connect a PC or other device to the transceiver.
L
See “FSK and AFSK connections” for the BASIC
MANUAL.
2.
Set the operating frequency and mode.
3.
Refer to the application software for
communication details.
L
When operating in the SSB data mode, adjust the
device’s output level within the ALC zone.
TIP:
The carrier point is displayed when operating AFSK in
the SSB data mode.
