[bars] A DX Crystal Set

[n1hts at comcast.net]

I may have enough germanium diodes to pass around

for a club build night. I can check if needed.


Round oatmeal box crystal radios are out there with a quick

google search. Also look at http://www.crystalradio.net/ for

ideas. Don't forget Chuck Kitchin's (sp?) BARS build session years

ago. That was well published along with Dan Raisbeck's picture

seen tuning one.


I also have old unused Gillette razor blades for a foxhole radio

some day.
