Yep, it’s Christmas again, and I’m such a geek, I can imagine all sorts of things that link it back to radio stuff. If you follow the link below, you’ll find that one of the first (if not the first) audio broadcasts was made on Christmas Eve, 1906, by Canadian scientist Reginald Fessenden. These first radio transmissions were made down at the very bottom of the radio spectrum, at frequencies of just a few kilohertz, and were produced by an alternator, which served as a mechanical oscillator to produce continuous waves. Very cool. You can read more about Fessenden on his Wikipedia page:

Oh, and Merry Christmas!
