[Boatanchors] IN34A 1N60 detector diode question

[Al Klase]

Hi Greg,

We went 'round and 'round with this in the crystal radio community.  It 
turns out that parts numbers have very little meaning.  Dump out your 
germanium drawer, and sort for the best performing units.  Some of the 
later small glass diodes from the orient, like the ones Radio Shack used 
to sell are statistically better.  Schottkeys may have an edge under 
special circumstances, but the impedance matching needs to be just so.

More than you wanted to know about this on Ben Tongue's (Think 
Blonder-Tongue) site:  http://www.bentongue.com/xtalset/xtalset.html
