This little project is a sure interest grabber with students of electronics of any age! Recommended for Boy Scout Merit Badge and Cub Scout Activity for requirements. It does not require a great amount of skill, but a little application will produce a good basic radio receiver. Construction is fairly simple. This radio DOES NOT require batteries to operate, using simple electrical principles to power itself. It does not include the Double Headset shown but does include a Crystal Earphone. Tuning is done by rubbing a piece of metal (large paper clip included in kit) across the coil of wire which is wrapped around a toilet paper tube.
The best antenna for this radio can simply be a really long wire, mounted as high above the ground as you can make
it. Though sometimes just connecting the antenna lead to a bed spring can bring surprising results, especially in city
areas, or close in to a transmitter station in the country.
