Not redefining -- the FCC had always defined all digital modes to be a
"radioteletype" emission mode. It is just lawyer-talk. As far as the FCC is
concerned, radioteletype is not restricted to binary FSK. The intent is pretty
clear from the Report and Order -- PSK31 and Pactor only.
There is one additional "fine print" that folks who want to use 60m for PSK31
will need to pay attention to: even though each 60m channel is as wide as a
voice channel and should technically be able to take multiple PSK31 signals, we
are only allowed one single PSK31 signal whose carrier is right smack in the
center of a channel. The same restriction holds for CW, too. Hey, it makes
searching for the QSX of a split DX much easier :-) :-).
