High performance Heathkit CR1 crystal radio. I have made a working prototype of a small and cheap crystal radio based on the Heathkit CR1 A crystal radio project for advanced students and hobbyists If you like reading about building home made radios up from scratch, perhaps you would like My Magnum Opus homebrewed ham radio project. The Heathkit CR-1 Over a period of about five years (1957 - 1962) Heathkit also sold a crystal radio set kit, the CR-1. This radio, like most, tuned the AM broadcast band from 540 KHz to 1600 KHz (kc in those days). The CR-1 is a simple kit that uses a sealed crystal diode instead of a 'cats- whisker'.
