4 RECEIVE AND TRANSMIT ■ PSK operation A high-quality DSP-based PSK encoder/decoder is built-in to the IC-7600. When connecting a PC keyboard (pgs. 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 PSK mode is 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 display the decode screen. • The IC-7600 has a built-in PSK decoder. r T une 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 Press [F12] of the connected keyboard to transmit. • [TX] indicator lights red. y T ype from the connected keyboard to enter the message that you want to transmit. • The typewritten contents are indicated in the TX buffer screen and transmitted immediately. • The text color will be changed when transmitted. • Press one of [F1]-[F8] to transmit the TX memory contents. u Press [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 T ype from the connected keyboard to enter the message that you want to transmit. • The message is shown in the TX buffer screen. e P ress [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, press [F12] twice. r Press [F12] of the keyboard to return to receive.

PSK operation

A h±gh-qual±ty DSP-based PSK encoder/decoder ±s

bu±lt-±n to the IC-7600. When connect±ng a PC key-

board (pgs. 18, 19), PSK operat±on can be performed

w±thout PSK software ±nstalled on your PC.

If des±red, you can also use your PSK software; con-

sult the manual that comes w±th the software.

Push a band key to select the des±red band.

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.

Push

[DECODE]

(F-3)

to d±splay the decode

screen.

• The IC-7600 has a bu±lt-±n PSK decoder.

Tune to the des±red s±gnal w±th the ma±n d±al.

•

The s±gnal ±s properly tuned when the rad±ated l±nes

±n the vector tun±ng ±nd±cator narrow, as show ±n the

example below.

•

The rad±ated l±nes ±n the vector tun±ng ±nd±cator may be

d±splayed sporad±cally.

•

When a PSK s±gnal ±s rece±ved, the water-fall d±splay ±s

act±vated.

•

The water-fall d±splay shows the s±gnals w±th±n the pass-

band. Rece±ved PSK s±gnals appear as vert±cal l±nes.

Press

[F12]

of the connected keyboard to transm±t.

• [TX] ±nd±cator l±ghts red.

Type from the connected keyboard to enter the

message that you want to transm±t.

•

The typewr±tten contents are ±nd±cated ±n the TX buffer

screen and transm±tted ±mmed±ately.

• The text color w±ll be changed when transm±tted.

•

Press one of

[F1]

–

[F8]

to transm±t the TX memory con-

tents.

Press

[F12]

of the keyboard to return to rece±ve.

✔

For your convenience

The transm±ss±on contents can be typed before be±ng

transm±tted.

Perform the steps

above.

Type from the connected keyboard to enter the

message that you want to transm±t.

•

The message ±s shown ±n the TX buffer screen.

Press

[F12]

of the connected keyboard to transm±t

the message.

•

The color of d±splayed text, ±n the TX buffer screen, w±ll

be changed when transm±tted.

• To cancel the transm±ss±on, press

[F12]

tw±ce.

Press

[F12]

of the keyboard to return to rece±ve.
