The W7ZOI crystal filter design and crystal measurement methods are described
in detail in _Experimental Methods in RF Design_, published by the ARRL and
available from numerous sources. It should be every serious experimenter's
library.

If you have access to old QSTs, you should be able to find articles
about measuring crystal parameters. Look especially for things by Wes
Hayward, W7ZOI. There's a fairly simple crystal-tester you can build
to measure enough parameters to extract equivalent L, Cs, Cp and R, I
believe. I 'spose someone will pop in with a more specific reference
for you.

I have a bunch of oddball crystals that I want to test. I know I can just
build up a generic oscillator to find the
resonant frequency, but out of curiousity I would like to
know the quality of the things, too.

Anyone know of any neat ideas for measuring the Q of a
crystal?

I would welcome any and all suggestions,
