Bob McGwier is an interesting fellow. I met him at Dayton many years back when TAPR was just getting into DSP devices: <a href="http:&#x2F;&#x2F;www.arrl.org&#x2F;news&#x2F;tom-clark-k3io-to-speak-at-amsat-tapr-banquet" rel="nofollow">http:&#x2F;&#x2F;www.arrl.org&#x2F;news&#x2F;tom-clark-k3io-to-speak-at-amsat-ta...</a>.  I think he was doing work for a defense research outfit at the time.<p>Getting way off the topic, some of the events at Dayton are quite interesting. At one dinner, I got to hear Joe Taylor <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Joseph_Hooton_Taylor,_Jr" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Joseph_Hooton_Taylor,_Jr</a> speak about his work on pulsars.  He brought some audio clips of pulsars, the first gave a &quot;click&quot; about once a second. The second clip was at ten per second, and the final one produced a tone of 600 clicks per second.  He credits his interest in physics (along with his brother) to amateur radio as a young boy.
