As was mentioned in another reply, the HP320LX does not have soundcard capability, you will need a radio capable of transmitting and receiving SSB, and there does not seem to be PSK-31 software available for Win CE.

Other digtal modes like packet or RTTY may be possible by using an outboard controller, but you asked about PSK :-)

Starting from scratch:
About the minimum laptop would be a P100, 8 Meg Ram, 1 Gig hard disk, SoundBlaster compatible soundcard, Windows 95. The local used computer store or eBay has thousands of possible candidates.

That said, I use a Toshiba Libretto 50CT for portable PSK: P75, 16 Meg Ram, 6 Gig Hard disk, Win 98Se, modified soundcard to provide an audio input (not for the faint hearted). It is about the same size as the HP320LX. Look for a Libretto 100CT, it already has the soundcard connections. I use the Digipan software (which works well).

I use a homebrew interface similar to the Buxcom Rascal (kit) or the commercially available Rigblaster Nomic.

For a ready-to-go commerial radio, you may look at something like the Yaesu FT-817, SGC 2020, or the Ten-Tec Argo V.

Small Wonder Labs has single band PSK radio kits. They include the interface, run a couple of watts out, and work well.

With the Libretto 50CT (used), a 80M Warbler kit, and some solder work, I got PSK-31 on the air for about $200.00.

If you can't build and have to buy all commercial, you could spend $1000.00-$1500.00 or so.

Have fun :-)
