So it's been a lousy day reading rev2 of RoHS II. In my 14year history of CE
marking directive study I've never had quite such a sinking feeling at the pit
of my stomache...so John's statement brings back a nice memory.
When I was a lad of 10 I spent the summer with a crazy uncle who had all
manner of strange and wonderful surplus gear in his basement. One device was a
crystal of germanium clamped in a steel "anvil", and installed above it was a
curl of tin wire. With a single wire lead antenna attached, and if you could
poke the tin whisker into the crystal just right, the broad cast of a local AM
station would sound in the ear-piece. Such a magical event, to tease voices
out of the organo*-mechanical device. A feeling absent from my ipod.
So I'll chime in too, that I've used crystal sets.

As I said. Unlike most here, I've used crystal sets.
