Detector Crystal
Radio Kit
Tap into the signals in
the skies
Learn basic
electronics as you build a working diode radio
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.
