Listen to "El Silbo" Voice-Powered Rig!

POWER SUPPLY

Michael, AA1TJ, has had more contacts with his voice-powered DSB rig. (Scroll down a bit for a look at the schematic and more comments on this amazing project.) Michael has posted two recordings of his signal (as received at distant stations). When I played these files, Ubuntu showed one of those semi-psychedelic groovy "visualizer" displays, complete with oscilloscope-like patterns; the signal looked FB Michael!

    Reading at the circuit diagram is bad for the head. I keep looking for the power connection...

    This is astounding. The only similar thing I've found over the years is a Japanese OM who did this - http://www.intio.or.jp/jf10zl/plam.htm - Similar, but not as elegant.

    The audio samples are eerie; remind me of those audiograms recorded back in the 1860s...you know, the woman singing the French folksong snippet...
