Hi John and readers,
The important bit is what is that neon lamp for? I honestly would like to
know since I have never seen one used in a crystal set before. Please
reply via p-mail or e-mail as I don't read every single TECH bulletin.
Thanks in advance.
Ah, you take me back to when I built my very first "rig" out of some junk
box parts. The variable inductor was hand wound on an old oatmeal box and
the slider cut from the copper strap used as a magnetic shield on an old
TV power transformer. Since all I had for a detector was a small selenium
stack rectifier I was amazed the darn thing actually worked. The antenna
was a 50' wire strung between the trees in the back yard. I received
several local MW stations in the NYC metro area loud and clear in a pair
of Brush 2K ohm headphones. Later I came across an old lead mine from
colonial days and picked up off the ground a pocket full of galena and
made quite a few of the old cat's whisker detectors from it, right down
to potting the crystals in lead holders. (Mom didn't like the idea of
melting down a bunch of old fishing weights in one of her pots, hi.)
That's a rather elaborite design for a crystal set, but one of the best I
have seen. Thanks for keeping those things alive, perhaps they will
remind us of the early days and prompt some to learn about the history
and development of radio.
