ADVANCED OPERATIONS
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, JT65B, or FT8 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 1-4 for details.
2. Set the operating frequency and mode.
Data 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.
The following are automatically changed:
- Changes the TBW setting from the SSB set to the
SSB-D.
- Changes the filter selection from the SSB filter set
to the SSB-D. (However, you can still adjust the set
receive IF filter bandwidths by touching the filter
icon for 1 second.)
- Enables the 1/4 Tuning function setting on the
FUNCTION screen.
- Disables the RX Tone Control settings, the Speech
Compressor function, and the Drive Gain adjust
level.
TIP: The carrier point is displayed when operating
AFSK in the SSB data mode.
See the illustration below for a tone-pair example in
the LSB mode.

Transverter operation
You can use the Transverter function as an exciter for
a transverter.
D Transverter setting example
This is an example of operating a 144 MHz band
transverter using the IC-7760's 50 MHz band.
1. Connect the 144 MHz band transverter's RF
output to [X-VERTER].
2. Set the operating band and mode.
(Example: 50 MHz band (MAIN), SSB)
3. Rotate
MAIN DIAL
(Example: 50.000.00)
4. Set "Transverter function" to ON.
» SET > Function > Transverter Function
MENU
5. Set "Transverter Offset." (Example: 94.000)
» SET > Function > Transverter Offset
• The offset frequency (94.000) set in this item is
added to the operating frequency (50.000.00) to
operate the 144 MHz band transverter.
L The first digit "1" is not displayed.
Therefore, 144 MHz is displayed as "44.000.000."
6. To close the FUNCTION screen, push
several times.
Displayed while the Transverter function is ON.
144.000.00 MHz
7. Rotate
MAIN DIAL

to set the frequency.
EXIT
145.000.00 MHz
to set the frequency.
