Very Simple

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.

Here are a few schematics;

This is what you will find when you click on one of the images;

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.
