2. ADVANCED OPERATIONS
Duplex operation
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.

Data communication
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 page 18-1 for details.
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.
