Very Simple

Post by Jim K on Tue Dec 11, 2012 12:46 am

Back in about 74, I took a begining electronics class in high school. The first project was an AM radio, with about half a dozen parts, with an earphone - no power, but picked up a few stations. I thought that was the greatest thing.
Havn't been able to find instructions for one that simple anywhere, back then it was about a buck in parts.

Jim here is a link to a good site for crystal radio parts;

www.crystalradiosupply.com

I have ordered from them and find them to be very reliable.

Cool, thanks Mezlaw, I've recently started using the image search engines to identify some of my yard sale finds, somtimes makes it easier to pinpoint what I'm looking for.
