Homemade Crystal Radio in Well-Constructed Oak Box

This crystal radio is likely from the early 1920s. It has a composition front panel that is attached to a nicely constructed and finished oak box. The tuning coil and capacitor are inside the box.

The front panel has connections for earphones, a ground, and an antenna (aerial).

The cat’s whisker detector is of special note due to the nicely ground crystal it rests upon. The ground crystal presents a smooth surface over which the whisker can easily slide. This increases the likelihood that a good conduction point will be quickly found.
