Section 97.307(a) is the closest regulation we have pertaining occupied 
bandwidth in the American amateur service.  However, some folks have argued 
that Sections 2.201 and 2.202 apply to the Part 97 service since Section 
97.307(a) states:

"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."

Then, Section 2.202 defines "necessary bandwidth" and "occupied bandwidth" 
based on class of service.



Reading Sections 2.201-2.202 together, the FCC has already incorporated much 
of the ITU's bandwidth and emission designators from Appendix 1 of its 
bandwidth recommendations.


To the best of my knowledge, the FCC has never formally relied upon Sections 
2.201-2.202 when addressing bandwidth concerns in the Part 97 service.
