5 ASSISTING YOUR SMOOTH QSO 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 [ ] (F1). 6 Press [ESC] to exit. ReversING 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 Reversed (the lower sideband and upper sideband frequencies are Reversed), 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 SSBDATA 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. {page 9-6} 5-64 Index Contents
