The problem with PACTOR III is that it is downward compatible with narrower modes PACTOR AND PACTOR II. The 500 kHz mode is compatible with narrow modes in the CW sections. The wide mode is only compatible with SSB. If you look at the SCS website, they promote PACTOR III as a commercial mode mostly for maritime operation. The rules in the US seem to prohibit PACTOR III if it is downward compatible. I still believe that if you can afford a sea going yacht you can afford the appropriate non amateur communications systems that are much more reliable.
