■
PSK operation
A high-quality DSP-based PSK encoder/decoder
is built-in to the IC-7600. When connecting a PC
keyboard (pp. 18, 19), PSK operation can be
performed without PSK software installed on your PC.
If desired, you can also use your PSK software.
Consult the manual that comes with the software.
q
Push a band key to select the desired band.
w
Push
[RTTY/PSK] to select PSK.
• After the PSK mode is selected, hold down
[RTTY/PSK] for 1 second to toggle between the PSK
and PSK-R modes.
• “PSK” or “PSK-R” appears.
e
Push
[DECODE] (F-3) to display the decode
screen.
• The IC-7600 has a built-in PSK decoder.
r
Tune to the desired signal with the main dial.
• The signal is properly tuned when the radiated lines
in the vector tuning indicator narrow, as show in the
example below.
• The radiated lines in the vector tuning indicator may be
displayed sporadically.
• When a PSK signal is received, the water-fall display is
activated.
• The water-fall display shows the signals within the
passband. Received PSK signals appear as vertical
lines.
t
Push
[F12] of the connected keyboard to transmit.
• [TX] indicator lights red.
y
Type on the connected keyboard to enter the
message that you want to transmit.
• The typewritten contents are displayed in the TX buffer
screen and transmitted immediately.
• The text color will change when transmitted.
• Push one of
[F1]–[F8] to transmit the TX memory
contents.
u
Push
[F12] of the keyboard to return to receive.
For your convenience
✓
The transmission contents can be typed before being
transmitted.
q
Perform the steps
q
to
r
above.
w
Type on the connected keyboard to enter the
message that you want to transmit.
• The message is shown in the TX buffer screen.
e
Push
[F12] of the connected keyboard to transmit
the message.
• The color of displayed text, in the TX buffer screen, will
be changed when transmitted.
• To cancel the transmission, push
[F12] twice.
r
Push
[F12] of the keyboard to return to receive.
