This has been bubbling a bit inside me for awhile, but why the hell would the FCC ever want to increase part 15 power? All that would accomplish is more noise on an already noisey spectrum. The CFLs, dimmers, AC motors, TVs, all radiate under current part 15 regs. By loosening regulations we’d be shooting ourselves in the foot.
Part 15 was never in anyway meant for broadcasting, if anything it was intended for experimentation. Thats why there are field strength limits or antenna limits. They intended somebody with electrical RF background to be messing with this stuff. Someone with the proper equipment and know-how. Not average Joe Blow grabbing a transmitter and playing radio.
It just so happens we get lucky with part 15 AM being simple enough to stay legal and get some use out of it.
FM is obviously not meant for any useful range, and never will be.
