LB3RE sent me a link to this awesome HF beacon by Anthony, F4GOH and Christophe, F4GOJ that has many of the same features as my (as yet still in-progress) beacon transmitter does. And, of course, his actually exists, so it’s already infinitely more awesome than my idea.

I was particularly interested in his very simple power amplifier using 4 ganged BS170s. I’m likely to be operating mostly on 30m, so I think I could probably get buy with a single harmonic filter, and I am not imagining that I need all the relay switching, but there is some good information to be mined in there.
