[R-390] Product Detector Article

[Stan Gammons]

Thanks for the article.

Since we are talking about product detectors, has anyone here made an 
external product detector?  I've seen one that Treetop circuits sells.  
I also thought about making one with something like an MC1496.  But, 
that's project for later.
