Treat yourself today to an experience in radio enthusiasm and innovation: Go to AA1TJ's blog and read about his latest creation: The Schmidtschem. Michael begins his post this way:
I've dreamed and schemed, off and on, for the last twenty five years over the prospect of constructing a complete, high-frequency (HF) amateur radio station without the use of vacuum tubes or semiconductors... Having considered and subsequently rejected a number of esoteric possibilities, I eventually concluded that a system based on electromagnetic alternators was the most promising.
He has a prototype on the air, using it with a no-gain receiver, and he is making a lot of contacts. Check it out: http://aa1tj.blogspot.com/

This was really interesting. I visited AA1TJ's site and read some more about this. It's really neat that people are exploring some of those roads less taken, sometimes really amazing discoveries are made there (and if not, it's still just really cool and fun). AA1TJ in particular is a very interesting ham and I like hearing about the latest inventions coming from the "hobbit hole".
