I'm not sure where this misinformation came from, but Part 15 doesn't 
state anything about 100mw on FM, to my memory. Field strength limits 
exist for all frequencies, save for those under 9KHz. There are other 

Take a look at Part 15 of Chapter 1 of Title 47.

Some relevant parts are listed below:
Sec.  15.209  Radiated emission limits; general requirements.
Sec.  15.219  Operation in the band 510-1705 kHz.
Sec.  15.239  Operation in the band 88-108 MHz.
