That sinking feeling is due to all the toxins you ingested before RoHS saved your corporeal being. I grew up in a house panted with 'coach paint', which has so much lead in it that when you burn it off, you can see the drops of lead. Although I never chewed the window sills, as it is alleged children did, I would undoubtedly have been a genius were it not for the neurotoxic effects.

I expected that there would be others. My detectors were galena (lead sulfide, non-RoHS!)/ phosphor-bronze, although I did have what I suppose was a zincite/bornite one for a few days until one crystal detached from its mount. Last year someone gave me some 1920s parts and I built a set with a Schottky diode, but I don't have a 50 ft antenna now, so I don't really know how well it works. -- OOO - Own Opinions Only.
