Okay, so how is that tested?  White noise?  Tones?  Voice?  Max power?  Max allowed ALC?  No ALC?
 
 Come on Michael, there's no way that would be anything but arbitrary, as a lot of the ARRL's "measurements" already are.

The market could take of the enforcement, Joe. Add the spectral mask to
the part 97, and then overlay the mask on the ARRL product test report
IMD plots. You can bet your bottom dollar that this would light a fire
under the butts of the manufacturers to clean up their act. No manufacturer
would want to have a review showing that their product was outside a
part 97 spectral mask. Now granted this wouldn't prevent users from
turning the knobs all the way clockwise and screwing things up, but at least
with a spectral mask and the aforementioned marketing pressure, rigs
would be capable of clean operation "out-of-the-box", something that
isn't always the case right now. Heck with this approach, you might
even see manufacturers advertising their superior transmitter IMD they
way they are now touting  low phase-noise and excellent receiver dynamic
range.
