73 magazine '92 crystal tester

[Bob Hardie- W5UQ]

if you have a signal gen and an oscilloscope you can test crystals.  Run 
the sig gen through the crystal to the input of the scope.  When the Sig 
Gen hits the freq of the xtal, it will pass the signal.  After a while, 
when you've checked several crystals, you will develop a sense of what 
is good and what is bad.  A good, very active crystal will cause the 
scope display to peak and bounce where a soft crystal will have no 
bounce and not a good peak.  Try it, you'll like it.
