Besides the legal chalenges, the 1 watt area is kind of a no-man’s land for Amplitude Modulation.
You can sort of tease out the milliwat power from a buffered ocillator,
or you can build an ocillator with a that’s a part of a much more powerful transmitter (10 watts and above)
or you can use a CW QRP unit and add a modulator section, but it won’t modualte very well because of the poor bandwidth at the lower power level.
I dunno, maybe a different approach?
Experimental broadcasting for a better tomorrow!
