Isn’t there a medfer beacon reg in part 15, or maybe 73, that allows certain unlicensed AM BCB activity on CW if the timing of the pulse meets certain parameters?
I think I might have read this in an old Radio Shack electronics booklet (remember the little dedicated-topic, small format booklets RS used to sell?) called “Communications Circuits” or something like that. IIRC, it was in support of a schematic for a little one transistor CW transmitter with a loading coil made of wire wound on a soda straw?
Experimental broadcasting for a better tomorrow!
