The text in the R&O indicates that the 500Hz maximum occupied bandwidth only applies to the new emissions designators added to the definition of data. and the affected bands are below 30 MHz. This is what I asked for in my petition. However, the FCC did put J2D in the list of 500Hz maximum occupied bandwidth emissions designators. I am not sure why this was added, or if it was a mistake. My guess is that it should have read:
emissions A1C, F1C, F2C, J2C, and J3C having an occupied bandwidth of 500 Hz or less when transmitted on an amateur service frequency below 30 MHz, and J2D.
I think the and J2D ended up in the wrong spot.
Unless the list is changed, the list of 500Hz maximum occupied bandwidth emissions designators are:
A1C, F1C, F2C, J2C, J3C, and J2D. The other emissions designators which do not fall under the 500 Hz maximum occupied bandwidth are those with:
A, C, D, F, G, H, J or R as the first symbol; 1 as the second symbol; D as the third symbol, so a general statement that "they are no longer going to
permit ANY wide band digital modes in the CW/data sub band" is incorrect. Only images and digital signals input into the mic or accessory jack of a SSB transmitter and transmitted below 30 MHz are under the 500Hz limit. Even if this was a mistake, I think you will find a majority of amateur radio operators are happy with this decision.
Why did not the FCC allow wide data modes in the phone area other than the usual image modes? No one asked for that in PR Docket 04-140. No one has asked because this will be a very unpopular request with the majority of the amateur radio community. This is one reason that the ARRL petition to regulate by bandwidth is so unpopular.

Am I reading this correctly to say that they are no longer going to__._,_.___
permit ANY wide band digital modes in the CW/data sub band? I got the
impression in the R&O that the FCC meant that any new modes using image
came under the 500 Hz requireement. But this seems to say that basically
no modes can exceed 500 Hz in the RTTY/Data/CW sub bands.
