[ARC5] Crystal Question

Wayne,
 
I never considered whether a frequency xtal would work as a detector,  
interesting concept.
 
The original foxhole radios were made with whatever was available.   Coils 
wrapped around about anything nonconductive, cereal boxes, wood,  etc.  
Capacitors were made from foil and whatever was nonconductive, e.g.  paper.  
Detectors were pieces of galena (i.e."cat wiskers"), razor blades,  etc.  As a 
kid growing up in Pittsburgh, I made several of these, and they  actually 
worked.  Of course, about the only thing they'd pick up is clear  channel KDKA.
 
As a source for information, check old Boy Scout books.  Seemed that's  
where I got my plans.
