I dunno, that photo of the modulation envelope looks pretty distorted to me, probably at least 10% THD, I would guess.

I'm surprised that they use bargain-basement components like the 2N222 and LM386. Since they obviously are trying to market this transmitter as something better than a typical Ramsey kit, you'd expect them to use higher-quality components.

Well, it's true those are inexpensive components which have been around forever... but the 386 is an excellent choice for transmitter audio at this power level.
Lou Burke, who is the consultant associated with that page, is is an excellent broadcast engineer located in the Phoenix area. It's great to see someone with his qualifications doing Part 15.

$175.00 for plans and a PCB only? a little too much if you ask me. Overpriced like another transmitter we know.
A SSTRAN work just as good for half the price.
