Then... I find a 433MHz radio that delivers +20dBm (100mw).

By my reading of 15.209, that's overpowered unless operating with a
miserable -9dB gain antenna. From the manufacturers web pile at:
http://www.hoperf.com/rf_fsk/
they offer +10, +13, and +20dBm outputs and claim they all meet ETSI
and FCC regs. I dunno about that.

Well, I can't argue with the fact that they are being produced. If they
really meet the FCC regulations, I have been unable to prove it. I have
looked all over the FCC site under part 15 and never found an area that
allows such power.

If you ever find it, I would appreciate a link to it.

Unless I missed something, you're correct. I can't find anything in
the US rules (except Part 47 ham radio) that allows milliwatt level
operation on 433MHz. It is allowed in Europe under CEPT rules to 10mw
at 10% max duty cycle:

(MS Word Document). Nothing that allows 100mw but possibly in another
foreign country.

I've only done certifications for 900MHz, 2.4GHz, and 5.7GHz, FCC
15.247 hardware. The 433MHz stuff is new to me. FCC 15.247 allows 1
watt into 6dBi.
