2. ADVANCED OPERATIONS

Data mode (AFSK) operation

You can operate in a data mode using AFSK (Audio
Frequency Shift Keying).
L When operating RTTY in the AFSK mode, PSK31
or JT65 with a PC application software, refer to the
software's instruction manual.
1. Connect a PC or other device to the transceiver.
2. Set the operating band and data operating mode.
(Example: 50 MHz band, FM-D1)
Data mode
3. Refer to your application software manual for
setting and communication details.
L When operating in the SSB data mode, adjust the
device's output level to be within the ALC zone.
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-7610'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. Turn ON the "Transverter function" in the
following item (Example: 94 MHz).
» SET > Function > Transverter Function
MENU
5. Set the "Transverter Offset" in the following item.
» SET > Function > Transverter Offset
MENU
• 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 irst digit "1" is not displayed.
Therefore, 144 MHz is displayed as "44.000.000."
6. Push EXIT several times to close the SET screen.
