Where in this instance does the reference to Part 15.209 come into play??? I believe you have a mental block going on somewhere which prevents you from understanding what you are reading!
My reading and comprehension skills are not the problem.
You quoted only 15.219, but Part C includes Parts 15.201 through 15.255 -- including 15.209.
See for yourself using the link below.

Yes it is Mr. Fry... let's read this together if you will, you cited:
TITLE 47--TELECOMMUNICATION
CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
PART 15_RADIO FREQUENCY DEVICES--Table of Contents
Subpart C_Intentional Radiators
Sec. 15.201 Equipment authorization requirement.
(a) Intentional radiators operated as carrier current systems,
devices operated under the provisions of Sec.
Sec. 15.211, 15.213, and 15.221, and devices operating below 490 kHz in which all emissions are at least 40 dB below the limits in Sec. 15.209 shall be verified pursuant to the procedures in Subpart J of part 2 of this chapter prior to marketing.
(b) Except as otherwise exempted in paragraph (c) of this section
and in Sec. 15.23 of this part, all intentional radiators operating
under the provisions of this part shall be certificated by the
Commission pursuant to the procedures in subpart J of part 2 of this
chapter prior to marketing.
I omitted the sections in the above not pertaining to this but anyone can look it up.
Sec 15.211 : Tunnel radio systems. (not your typical 100mw transmitter)
Sec 15.213: Cable locating equipment. (Hobbyist on 100mw transmitter have no need for this)
Sec. 15.221 Operation in the band 525-1705 kHz.
(a) Carrier current systems and transmitters employing a leaky
coaxial cable as the radiating antenna may operate in the band 525-1705
kHz provided the field strength levels of the radiated emissions do not
exceed 15 uV/
[[Page 810]]
m, as measured at a distance of 47,715/(frequency in kHz) meters
(equivalent to Lambda/2Pi) from the electric power line or the coaxial
cable, respectively. The field strength levels of emissions outside this
band shall not exceed the general radiated emission limits in Sec.
15.209.
(b) As an alternative to the provisions in paragraph (a) of this
section, intentional radiators used for the operation of an AM broadcast
station on a college or university campus or on the campus of any other
education institution may comply with the following:
(1) On the campus, the field strength of emissions appearing outside
of this frequency band shall not exceed the general radiated emission
limits shown in Sec. 15.209 as measured from the radiating source.
There is no limit on the field strength of emissions appearing within
this frequency band, except that the provisions of Sec. 15.5 continue
to comply.
(2) At the perimeter of the campus, the field strength of any
emissions, including those within the frequency band 525-1705 kHz, shall
not exceed the general radiated emission in Sec. 15.209.
This is the one throwing Mr. Fry in a loop...
Then we have:
Sec 15.23: Home-built devices (We all know this infamous little rule)
Then if you read on you get:
TITLE 47--TELECOMMUNICATION
CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
PART 15_RADIO FREQUENCY DEVICES--Table of Contents
Subpart C_Intentional Radiators
Sec. 15.215 Additional provisions to the general radiated emission limitations.
(a) The regulations in Sec. Sec. 15.217 through 15.257 provide
alternatives to the general radiated emission limits for intentional
radiators operating in specified frequency bands. Unless otherwise
stated, there are no restrictions as to the types of operation permitted
under these sections.
This quote above is the GEM that allows Part 15.219 to stand alone without Part 15.209 requiremnts to supercede the Part 15.219 rule.
There you have it Mr. Fry... you, me, and the rest of the board can clearly read the rules as you state, now it could be I missed something but having read the rules a million times and UNDERSTANDING what I'm reading it's clear you don't have the rational to understand the rules you read.
