Welcome to the PSK31 Info. Page!

All PSK31 requires is a PC running Windows 95 (or later),
a 16-bit sound card, a simple interface to your HF rig and
your choice of several freeware software programs.

14.070 USB is the most popular 20 meter frequency, but
other "hot" frequencies are popping up in the 40 meter,
15 meter and 10 meter CW/digital bands.
