Look at Part 97.221. This 500 hertz va 1600 hertz bandwidth thing is an automatic control (unattended - 500 hertz) or attended 1600 question.
I think you must be thinking about the 300 baud limit and blurring the two together. And no, I have no other FCC guidance on the matter.

That is the only thing I specifically see about bandwidth for data modes. I kinda read that as saying we here in the US are limited to 500 Hz bandwidth. Does anyone have an "official" clarification on this from the FCC.
