1934 One Tube Shortwave Receiver

1934JuneSWCraftCoverEighty-five years ago this month, the June 1934 issue of Short Wave Craft showed how to put together this one-tube receiver, which the magazine promised would pull in foreign stations with a ten foot antenna.

The set used a type 19 dual triode, one half of which was detector, with the other half serving as audio amplifier to drive the headphones. The set could be used either as regenerative or superregenerative. This meant that it had excellent sensitivity on AM signals in the superregenerative mode, but it could also be set as a standard regen to copy CW signals.

The author, George W. Shuart, W2AMN, reported that on the first night after building the set, he was pulling in German stations in the heart of downtown Manhattan. He promised that anyone who built the set would be more than pleased with its smooth performance and simplicity.
