You won't find much of this information without buying the tech manuals on
these aviation band radios and reading about them.

I was hoping to avoid the "overt plagiarism" approach - but I guess I
could reserve the option of "covert plagiarism"??? 8-)

High power VHF/UHF AM transmitters are also used as audio subcarrier
transmitters in System-L television, which is used at least in France.
These require "full" audio bandwidth and good linearity for low audio
distortion in normal TV receivers. The audio exciters used in low
power relays might be in your power range, so try to find some info
about these transmitters, most likely only in French.
