Build Your Own Shortwave Crystal Radio

A crystal radio is one that picks up AM radio signals without the use of batteries or electricity. The antenna picks up a radio wave, which is passed through the crystal detector, which then turns the wave into a signal that produces audio that can be heard through a headset.

This hobby of building and operating crystal radios became popular in the 1920's, when radio was in its early stages. In fact, they were the first radios used in many homes. Kits used during this time period actually used real mineral crystals as detectors, and a very fine wire, often referred to as a “cat's whisker”, was used to touch the crystal in various places until a station was found. Most people today use a diode instead of a crystal in these radios, but there are still some people who are enjoying crystal radio the old-fashioned way.

Here we will go over the basics of building your own crystal radio. Sure, there are all kinds of radios you can purchase that are ready to go, but building a crystal radio is loads of fun, and you will love the great reception you get with it.

Crystal Radio Components
The most important component of a crystal radio is the crystal, hence the name, crystal radio.

When you are building a crystal radio, you can get as elaborate as you want. There are many crystal radio kits available, ranging in price level and difficulty.

Before you jump right into building a crystal radio, you need to get yourself a good set of detailed instructions. There are all kinds available on the Internet, at little to no cost. Or, you can also purchase kits that have everything you need to build a crystal radio. Once you have the instructions, and have read them and understand the project, it's time to get to work. Now, you'll need to gather up everything you'll need, from supplies to tools, to make a crystal radio that you will be able to use for many years to come.
