"In 1999, a new kind of digital mode appeared. It's called PSK, for Phase Shift Keying, and it's known as a "sound card" digital mode because it uses a computer's sound card to encode and to decode the transmitted signal. Older digital modes like RTTY have been revitalized as "sound card" modes, and completely new modes like PSK and MFSK have appeared. The new modes are proving as popular with long time hams as they are with new hams, like me." Linux.com | Fldigi and amateur radio on Linux
