Crystal Radio Kit

Now your students can experience the fun of building a real working radio!

Students learn first-hand how radios operate, how electrical impulses are changed to sound, what a diode does, how to read a simple circuit diagram, and then perform simple experiments with different antennas.
Each kit comes complete with a crystal diode, tuning coil, tuner, plastic mount, antennas, alligator clips, hookup wires, and an earphone.
