With your Crystal Radio Kit you can tune in the AM Radio Band

(550-1600 KHz) and you don’t use batteries or AC power. It works on

the same principle as the early Crystal Radio, however the crystal has

been replaced with a more modern device called a Diode. The function

of a Diode is basically the same as the old Crystal but with the

advantages of being smaller and easier to use.
