Mike,
1. Download DigiPan from
www.digipan.net
2. Connect radio speaker or earphone jack to mic in on PC.
3. Tune to one of the many psk freq's on HF
1838.150
3580.150
7035.15 for region 1 and region 3, and 7080.15 for region 2 *
10142.150
14070.150
18100.150
21080.150 (although most activity can be found 10 kHz lower)
24920.150
28120.150
4. Enjoy listening and setting up to recieve PSK31.
To xmit, you will need some sort of interface to send the speaker out of your PC to your Mic or data input on the radio and that will key the PTT line. There are units for sale out there that interface to most radios and many DIY circuits that can be found on the web. I am by no means an expert on this, but have used it once in a while.
Let us know your progress Mike.
73 and Merry Christmas!
