Psk Operation - Icom IC-7600 Instruction Manual

■ PSK operation

A hgh-qualty DSP-based PSK encoder/decoder s
bult-n to the IC-7600. When connectng a PC key-
board (pgs. 18, 19), PSK operaton can be performed
wthout PSK software nstalled on your PC.
If desred, you can also use your PSK software; con-
sult the manual that comes wth the software.
q Push a band key to select the desred band.
w Push [RTTY/PSK] to select PSK.
• After PSK mode s selected, push and hold
[RTTY/PSK] for 1 sec. to toggle between PSK and
PSK-R modes.
• "PSK" or "PSK-R" appears.
e Push [DECODE] (F-3) to dsplay the decode
screen.
• The IC-7600 has a bult-n PSK decoder.
r Tune to the desred sgnal wth the man dal.
• The sgnal s properly tuned when the radated lnes
n the vector tunng ndcator narrow, as show n the
example below.
• The radated lnes n the vector tunng ndcator may be
dsplayed sporadcally.
• When a PSK sgnal s receved, the water-fall dsplay s
actvated.
• The water-fall dsplay shows the sgnals wthn the pass-
band. Receved PSK sgnals appear as vertcal lnes.
t Press [F12] of the connected keyboard to transmt.
• [TX] ndcator lghts red.
y Type from the connected keyboard to enter the
message that you want to transmt.
• The typewrtten contents are ndcated n the TX buffer
screen and transmtted mmedately.
• The text color wll be changed when transmtted.
• Press one of [F1]–[F8] to transmt the TX memory con-
tents.
u Press [F12] of the keyboard to return to receve.
✔ For your convenience
The transmsson contents can be typed before beng
transmtted.
q Perform the steps q to r above.
w Type from the connected keyboard to enter the
message that you want to transmt.
• The message s shown n the TX buffer screen.
e Press [F12] of the connected keyboard to transmt
the message.
• The color of dsplayed text, n the TX buffer screen, wll
be changed when transmtted.
• To cancel the transmsson, press [F12] twce.
r Press [F12] of the keyboard to return to receve.
