Andy, K0SM has a very nice look at the K3 reduced-bandwidth FSK keying. (Now available to all as Beta DSP rev. 2.8.)
http://www.frontiernet.net/~aflowers/k3beta/ It is also interesting to look at before and after FSK signals in the time domain. https://picasaweb.google.com/StarrGarretson/2013_03_25_K3_FSK K3 FSK has always had a small amplitude difference between mark and space. The transition has always been abrupt, Photo 1. With the new beta software, the transition is much more gentle, Photo 2. Bravo!
