no, the emission designators still exist and are referenced in part 97.

this is standard ESSB strawman answer, "hobbyists cannot measure occupied bandwidth."

the correct answer is in 97.307 (a) & (b).

(a) No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice.
(b) Emissions resulting from modulation must be confined to the band or segment available to the control operator. Emissions outside the necessary bandwidth must not cause splatter or keyclick interference to operations on adjacent frequencies.

and yes 97.307 (d) does state specific Db attenuation factors, but the bottom line is that it DOESN'T have to be exactly measured. read 97.307 (b) again.
