![]() The article that piqued my interest appears on 'Scott's Crystal Radios' website and makes for an inspirational read, eventually revealing the inside core arrangement of the ferrite-loaded tuned circuits via an actual X-ray of the device! By the way, if you are looking for a nice set of older headphones, Scott's website is the place to visit! ![]() I've been eager to get my mitts on one to see how it performs after reading of one DXer's fifty-eighth catch with his own CR-1! When it comes to crystal radios, there is nothing revolutionary regarding the CR-1’s basic circuitry but for some odd reason, it has achieved cult-like status as well as high dollar value. The article described one homebrewer’s attempt to duplicate the receiver and to learn more about the detector and antenna tuning ferrite-loaded coil's secrets. It began when I ran across an interesting description of Heathkit’s legendary CR-1, a double-tuned good performer and very much sought-after by collectors as well as by users. For the past several months my interest in ‘DX-crystal radio’ construction has been percolating once again.
