[Boatanchors] Crystal Set Progress

[Al Klase]

Bob,

Build this one: 
http://www.skywaves.ar88.net/xtal/PGXS-II_files/NJARC_PGXS-II.pdf

It only needs one variable cap, and doesn't require an engineering 
degree to operate, and I guarantee it will work at least as well as the 
one you're looking at. The article has a lot of detail on the problems 
you'll encounter, like how to wind the coil. At least read it.

Good luck,
Al
