Not at all. It just mandates a certain power input to the finals.

At one time it DID mandate something like "local communications only".
I can't remember the exact wording, so I leave it in quotes.

Note that Class D wasn't all there was. There was Class C which allowed
pulse modulation in the 26 MHz range for remote control, and Class A
citizens band which was AM in the 450 MHz range. I don't recall what
Class B was.

I had a class C and D license. The difference was ticking a box on the
application.

Geoff.

Since I never operated CB except for one short contact in my carpool
mate's car to show him how it worked, I was not intimately familiar
with CB rules. I seem to remember thought that there were regulation
which prohibited even attempting to make a contact of over 200 miles
(or so) even if conditions permitted this. I seem to remember that
this was one of the ways to attempt to rein in the use of powerful
amplifiers that many CBers used (of course the prohibition of the sale
of amps capable of operation in that range, including those intended
for ham use, was another FCC mandate.)

Anyone know more about that??

I don't know the licensing requirements, but I think that there is
also a frequency or frequencies at 72 MHZ available for radio control
of models in addition to 26MHz; and, 50 MHz if one is a licensed
amateur.

Anyone up on that?
