Eighty years ago this month, the March 1942 issue of Radio Craft carried the plans for this two-tube shortwave regenerative receiver. Thanks to the use of dual 1JG6 triodes, the set had four-tube performance. One half of the first tube was an untuned amplifier, which prevented the regenerative detector from radiating and messing with other sets in the neighborhood. The regeneration was controlled with a variable capacitor, and the second tube provided two stages of audio amplification.

With four plug-in coils, the set covered 145 through 10 meters. The compact size made the set ideal for portable operation.
