Roger, I will let Bonnie respond, but let me add my 2 cents. Paragraphs 15 through 19 address the rule changes which allow image emissions. Paragraph 19 has most of us confused because while it says "we will revise our rules to clarify that the 500 Hz limitation applies only to the emission types we are adding to the definition of data"; J2D was already in the definition of data before this revision. They also say "the 500 bandwidth limitation will not apply to other data emission types or amateur service bands in which a higher symbol rate or bandwidth currently is permitted. There is a footnote to that sentence that references 97.305(c), 97.307(f)(3)-(8), (13). This would indicate that the intention of the revision to the definition is to add image emissions that have a maximum occupied bandwidth of 500 Hz. I am not sure why J2D was moved into the less than 500Hz area. I would only be guessing if I gave my hypothesis.
