That's the last thing we "need" -- more bogus regulations that can't possibly 
be enforced without a dedicated staff that 99.99% of the taxpayers I'm sure 
don't want to pay for.

Besides, if they don't care now, they won't care if the rules change, either.

3kHz.<
You need a bit more of a spectral mask than just a bandwidth limit to ensure 
that Out of Band and Spurious Emissions (defined as per ITU Rec. SM329)
are adequately suppressed. That's why ITU have a 'necessary bandwidth' and an 
'occupied bandwidth'. Given that caveat, I agree.
Time was when someone told that they were splattering would do something about 
it. These days, too many don't know what to do and don't care.....
