[amsat-bb] Presentation--Introduction to Amateur radio?

Hi all,

I'm giving 2 talks in the next 2 weeks to two compeletey different audiences. This Thursday will be to the Johnston Amateur Radio Society, and I hope to do a live demonstration during the ~7pm Eastern pass of AO-51!

The point of this email, however, is that the following week I am going to talk about our satellites to non-hams.

Does anybody have an "Introduction to Amateur Radio" PowerPoint presentation (rather than an "Introduction to Satellites, which we have on our web site)?

Thanks in advance for any help...I figure why reinvent the wheel? :)
