CR-1 Heathkit Crystal Radio

CR-1

This crystal radio is just the ticket for construction by young people interested in radio or electronics—yet it is definitely not a toy. Employs high-quality standard components throughout. It is even usable as an AM tuner in high fidelity allications.

Covering from 540 to 1600 kc., the CR-1 has two high-Q tank circuits that employ ferrite core coils and conventional air tuned capacitors. Capacitors are tuned individually to the desired station. The receiver is most attractively styled in a black bakelite case. Uses a sealed germanium diode for detection—no cricital "cats whisker" adjustment. Includes a pair of high impedance earphones. Requires no external power. Could prove extremely valuable for emergency reception of civil defense signals, should there be a power failure. The construction manual provides the builder with the basic fundamentals of signal reception so that he understands how the crystal receiver functions. An interesting and valuable "do-it-yourself" project for all ages.
