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.

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.
