from ac4m:
PSK2K is a meteor scatter type of mode
written by DJ5HG
Using a modulation scheme of
Phase Shift Keying at 2000 bits per second also The pulse shape is a sinc-function. The result is a minimum-energy modulation, not a constant-amplitude modulation
Bandwidth : As a consequence of the sinc-pulse, the spectrum of the transmitted signal has a rectangular shape
of 2000 Hz width
Advantges of PSK2K is it is a fairly senstive mode
+you can have different intervals of calling and returning times
+and an automated QSO sequence option
- Not many people know about these advantages
only problem is that it requires a 120Mb download...
