That is intentional. Government entities like to have a law or rule
on the books that they can use only when they need or want to nail
somebody. 99.99% of the time it is intentionally never enforced but
when the time comes, it's there to be used at their discretion.
Other examples are the laws against vagrancy and disturbing the peace.
All governments do it.

## I will define it for you. Desired communications = 50 db over S-9. lol.
If we all used just enough power to be over the noise level, we would all be
running way less than 100w most of the time. The FCC has similar rules re
ssb
TX bandwidth..it has this quality wording in the clause. Any tx bw can be
used on ssb,
except here in canda..where we are limited to a measly 6 khz.
BTW, we are allowed 750w cxr on AM modes, with no limit on pep, so 5-6 x cxr is
just fine,
IE: 100-150% positive modulation..using neg clipping.. And this is measured
at the ant feedpoint.
So nothing changed here on AM from 40 years ago. You folks got screwed on
the AM power
rules with the 1.5 kw pep limit.
Its all a moot point anyway. Im sure anyone with a thunderbolt etc, is still
running it at 650-750w of cxr.
