[NJARC] Litzwire

[Al Klase]

Hi Henry,

Robert L. told part of the story.  I'll fill in a bit more.  E-bay is 
generally the only reasonable place, as you'd be fighting minimum order 
requirements if you go to a manufacturer.

The size of the wire is given by a pair of numbers like 175/46. That's 
175 strands of #46 enameled wire.  The size of the individual strands is 
targeted on a particular frequency range.  #44 or #46 is what you want 
for the broadcast band.

As a long-time crystal set builder, I remain unconvinced about the real 
world advantages of having a coil with a Q of 1000 versus the 200-300 
that attainable with normal wire.
See my article here: http://www.skywaves.ar88.net/Coils/Coilwiz.html and 
the main xtalset page: http://www.skywaves.ar88.net/xtal/xtal.htm

What are you up to?  If you've never played with a high-performance 
crystal set,I suggest that you keep it simple by buliding a PGSX Mark 
II, and then adding the "Front End" tuner to make it a really good 
crystal set.  Not a lot of expense or complication, and then you can use 
it as a point of comparison for further development. It's likely better 
than 99.99% of all the crystal set ever built.

Have fun,
Al
