Some of that information is in my summary of ARRL Lab tests.

FCC limits are not expressed well for those who deal only with numbers. 
What SHOULD be the dominant paragraph says that the bandwidth of a 
signal shall be the minimum required for the means of transmission. In 
practical terms, that means carefully shaped CW keying, minimum phase 
noise, minimum IMD. It's essentially a "state of the art" spec. But 
because there are no numbers attached, the paragraph is widely ignored.
