I’ve never seen data on using dynamic carrier control in Part 15 AM before, and if it would be okay. There was a transmitter from Panaxis called, I think, AM 100? Whatever it was called it was crystal controlled and used carrier shift to increase power when the modulation would peak up. I’m guessing that the no modulation carrier power was 100 mW..
I was having a discussion with a radio friend about that transmitter after we both saw it written up in Panaxis’ newsletter. I thought, “Ah, clever way to get more milliwatts!” and my friend thought it was because that transmitter was meant to feed a 4 watt linear amplifier for power line transmission, so that the transistors wouldn’t overheat and save power.
It might be something to look into again, since commercial broadcasters looking into and applying several different carrier control strategies now.
