Hi Mike:

I've received an email asking about where to purchase a crystal activity 
meter and although I have a hand held unit, see:
http://www.pacificsites.com/~brooke/Xam.html  don't want to part with it.
This is an older unit that uses PNP transistors.  I'm now thinking about 
how to build one using a PIC and to that end would like to see what's in 
the subject article.  So if you would email a copy to   
mailto:brooke at pacific.net?subject=Crystal_Test  that sure would help.

The final product should be a hand held battery powered easy to use device.

Have Fun,

Brooke Clarke
