It was radio engineer Mister Kit Knight who invented the Knight Kit Part 15 Transmitter way back in the 1950s. He is the Father of Part 15.
For the past half hour of so, I have been
doing a search for the HISTORY OF PART 15.
It is now about 6:17 PM EDT here, as I sit
typing this in.
That is really something. ESP?
Well, anyway - I found a really
facinating discussion from several years
ago, written mainly by our friend Ermi -
who knows so much. I don't know where
you are Ermi, but thank you for this. It's
really good.
Just type into Google, "ëarliest radio, part 15.us."
Part 15 started in 1938, for phono oscillators,
or "wireless phonographs," which is what they said
from my notes here from way back somewhere else.
It covered 300 kHz to 30 MHz. And it wasn't called
Part 15. There was another number designation for
the rules.
Any, that's it. Check it out. Thanks again Ermi.

Several of our other friends are in this
discussion, too, with really great info.
But I think Ermi is the guy who talks
about the early Part 15 regs.
It's quite a ways down the page.
Bruce
Too busy, too many distractions.
Sorry guys.
A BETTER LINK is:
Try Google: "Part 15 AM History Part 15 us"
I think this info is written in different
places over the years by Ermi, who did
the research, and Neil has a bunch of
comments that add more info.
I'm confused, but it's there somewhere.

Thank you Neil Radio8Z for making that 11-pager available.
The man's history goes into a lot of detail and makes the reader aware of how massive the over-all management of all the spectrum gets to be.
Being unlicensed is wonderful.
