SELECTING THE TIMESTAMP TIME

You can select whether the time configured for the Local

Clock or the Secondary Clock is applied to the time

displayed for the timestamp. Refer to "CLOCK DISPLAY

AND TIMER".

{page 15-1}}

1 Select Group No. 2, "Decoding & Encoding", from the

Menu screen.

2 Access Menu 14, "Clock (RTTY/PSK Time Stamp)".
3 Press [SELECT] (F4) to allow editing of the parameter

box.

4 Press [–] (F4) or [+] (F5), or rotate the MULTI/CH

control to select "Local Clock" or "Secondary Clock".

The default is "Lock Clock".

5 Press [

CONFIGURING THE PSK TONE FREQUENCY

You can configure the tone frequency for reception in PSK

mode.

[F1] [F7]

[FSK/PSK/REV]

[ESC]

[MULTI/CH]

1 Select Group No. 2, "Decoding & Encoding", from the

Menu screen.

2 Access Menu 11, "PSK Tone Frequency".
3 Press [SELECT] (F4) to allow editing of the parameter

box.

4 Press [-] (F4) or [+] (F5), or rotate the MULTI/CH

control to select "1.0 [kHz]", "1.5 [kHz]", or "2.0 [kHz]".

The default is "1.5 [kHz]"

6 Press [ESC] to exit.

REVERSEING THE PHASE CHANGE DIRECTION IN

QPSK

If the received PSK signal is not decoded properly, switch

the BFO frequency on the LSB side to that on the USB

side and try decoding the signal.

If the BFO frequency for the received PSK signal is

Reverseed (the lower sideband and upper sideband

frequencies are Reverseed), the PSK signal cannot be

decoded properly.

Pressing and holding [FSK/PSK/REV] allows the

decoding of the Reverse signal.

USING A PC TO COMMUNICATE IN PSK MODE

This is the method of operation in PSK mode using a PC,

instead of using the demodulator, encoder, and decoder

built in to the transceiver. Connect the transceiver and a

PC running applications supporting PSK communication

so that you can operate the transceiver in SSB or SSB-

DATA mode.

Refer to the following page for operation examples.

• CONNECTION TO A PC

{page 1-5}

Note:

◆ In the case of operation in the digital mode such as PSK31 using

a PC, you must adjust the audio output level from PC until the ALC

meter of the transceiver begins to swing.

Also, you must disable the speech processor.
