I get a flyer from the FAIR RADIO SALES Company in Lima,Ohio
and it is mostly full of old Army surplus radio stuff but the
latest ad sheet shows a pair of items that might be of interest
to crystal set builders or antique radio hobbyists. (1.) A kit
of parts to build a crystal set:10 sided loop antenna,germanium
detector diode,3 plate sliding capacitor,etc.: Selling for $27.95
and (2.)Crystal Receivers Book; 48 pages. Experimental crystal set info from 1911 and 1912, letters from builders and ideas on
how to build the things used in a crystal radio set.:$6.95 cool:
IF anyone is interested their website is :www.fairradio.com

Gatorade Frost

I built one for scouts about 10 years ago, but it didn't work. If someone makes a working crystal set radio let us know.

I used to build crystal sets back in the 1950s.

Here is some more info on modern xtal sets.

Thanks for the info. Looks like your site is better than the one
I posted about and might be what Gatorade Frost was looking for.
Seems like their radio kits are just what I would have wanted to
build .....a few years ago. Thanks.

I built one of these at an electronics fun class after a meeting of my local Ham Radio club when I was a teenager about 10 years ago. The one I built is pretty much identical to the schematic posted above. They're crude, but super fun to build / play with!
