[hpsdr] Basic HPSDR Presentation?

[John Ackermann N8UR]

Does anyone have a relatively current introductory Powerpoint (or other 
format) presentation on HPSDR, with some SDR basics and description of 
the HPSDR pieces?

I'm doing a presentation to a local club this week and find I don't have 
anything at an intro level that's not *really* old.  Would love to 
plagiarize... I mean, borrow with full credit given, a more up-to-date 
presentation from someone.

Thanks,

John
