Without comment on what you propose, I offer the following:
You wrote: “Part 15 was orginally dreamed up to regulate “intentional radiators” like garage door openers, wireless phones and microphones, computers, WiFi, digital samplers and such. Part 15 broadcasters take a slap in the chops when included with the rest of the intentional radiators.”
My research shows that part 15 AM was codified in 1938 to allow for “phono oscillators” which were phonographs which would transmit to the radios already in the home. The purpose was to reduce the costs of providing power amplifiers and speakers which already existed in the radios thus enabling people to buy phonographs at low cost. It was never intended to provide for community broadcasting.
Part 15 now includes the other devices which you cite because they are all unlicensed as are part15 transmitters.
