The plans for this handsome one-tube receiver appeared a hundred years ago this month in the May 1925 issue of Popular Science. The set was said to be ideal for the beginner, but still boasted long-distance reception. Regeneration was controlled by a variable capacitor, and this was said to reduce squealing, by virtue of the fact that only RF, and not audio, was fed back. The set called for an antenna of 75-100 feet. In testing, the set pulled in Chicago from a less than ideal location in New York.
