Christian, From a purely nostalgic viewpoint some of the older MFSK modes like Piccolo, Coquelet & Crowd could be a lot of fun to use on the amateur bands. Performance-wise they are probably eclipsed by MFSK16/Olivia but just as in Hellschreiber & even CW, performance isn't everything.
You could also consider Autospec, Twinplex & FEC-A too. 73 Sholto K7TMG Christian Crayton wrote: > > > If you could experiment with a mode for the first time, would you rather > try a new mode like Thor, or an old-school mode like CROWD or Piccolo? > I've been thinking about fiddling with FFT and programming, and have > thought about bringing some of the original digital modes used by > various diplomatic and military organizations back to life.
