I think I stand corrected.  When it was first discussed by ARRL, I got 
the impression that any digital mode was confined to PSK-ish bandwidths. 
  Looking up the current FCC regs, 2K80J2D is permitted, so 45.5 baud 
170 Hz shift RTTY would also be permitted.  I guess 2K80J2D is Pactor-3?

Given that we have moved from "A1"=Morse Telegraphy, "A2"=Audio 
Modulated Morse Telegraphy, and "A3"=AM Voice to 7, 8, and more 
characters in an emission type designator, it's not surprising that it 
got very complex.

Side gripe-ette:  I was sorry when ecfr.gov stopped publishing the 
entire Part in PDF.
