Hi Peter,

Here's a link with a much better version of the talk.  The talk you're 
looking for is the first on this page.

<http://openhpsdr.org/videos.php>

In this version, the original sound clips have been edited-in as have 
the original slides.  Dave, KV0S, did the hard work of editing.

I will take a look at your Yahoo group!  Sounds interesting!

73,

Warren  NR0V
