5 ASSISTING YOUR SMOOTH QSO

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 [ ] (F1).
6 Press [MENU] to exit.
PSK-RELATED CONFIGURATION

CONFIGURING THE PSK TONE FREQUENCY

You can configure the tone frequency for reception in PSK
mode.
[ESC] [FSK/PSK/REV]
[F1] [F7]
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.
5-60
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]"
5 Press [
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
[MULTI/CH]
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
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.
