Operating! PSK31
PSK31 … invented in late 1998 by Peter Martinez G3PLX
Keyboard - to - keyboard communications
- like RTTY
- far more accurate print (fewer errors due to QSB and QRM)
- excellent weak signal performance
- average stations can work the world
- but so-so on polar paths (polar flutter hurts performance)
- really low bandwidth… 31 hertz!
- More than 20 stations can theoretically operate within 1 kHz total bandwidth
