D-104 Microphone Xtal Element

[Don Buska]

Crystal mics don't last forever.  They usually loss it from picking up
moisture over the years from the surrounding environment and mouth.
I've never broken one from shock yet, but I'm sure they do have some
limitations there as well.

However, I currently use a EV Cardax mic as the number one mic in my
shack (See AM Side on http://www.qsl.net/n9oo) which is probably 30-40
years old.  It works great and it is crystal.
