Are you ready to tap into the signals in the skies? Build a radio that
functions without power from batteries or
a wall outlet! The Detector Radio works like early crystal radios, allowing you
to tune into radio stations using
electromagnetic power. Learn about HF coils, capacitors, resistors and diodes.
Discover how antennae work and experiment to improve your reception. Challenge
yourself to pick up
transmissions from far away. The simple design of the Detector Radio illustrates
the basic principles behind all radio broadcasting. Through 20 experiments in
the full
color, 32 page Experiment Manual, learn about the necessary components of a
radio and the role each one plays in bringing sound to your ear.
