Robert, typical 9600 packet sounds like "shhhhhhhh".  In some cases, it makes the static background quiet--rather than seeming to make much of a noise.

Your ear won't be able to tell GMSK from FSK...most modems can't tell the difference either :)

I've never heard 9600 that sounded like 1200...

I would fully expect the D700 to work on RAX.
