  1. Nice! Now I feel compelled to build this.

    Here's another ultra simple circuit I ran across on YouTube the other day (from Make magazine I believe). Super simple FM transmitter: https://www.youtube.com/watch?v=MMgzUGBfXiE&list=FL2K8XCApwENL4mlwOAyE9gA&feature=mh_lolz

  2. Egad! No output filter?! But then I guess it would no longer be "Super" and only a plain "Minimalist".

    Like Peter VK3YE, I am somewhat askance at the 700 mW claim. Be that as it may, Paulo certainly has a fab. web site for ham HB.

  3. Bill, I actually just built and tested this circuit. The TX gave me about 1/4 watt and the RX didn't work at all for me. Not sure what's wrong.

    I posted what I did on my blog if you're curious:

  4. Not sure if you read the older blog comments but just letting you know the RX works now too. I was just a little confused as to what I was seeing and I had to use an amplified speaker. I emailed Miguel and he agreed that the audio is a little weak (and he uses an ~500 ohm impedance telephone earpiece for his, which I don't have). I've been updating my blog with the evolution of the little circuit and put a demo of it on YouTube as well.
