1922 Simplest Radio Outfit

1922DecSciInvShown here from a hundred years ago is the 7th place winner in the “Simplest Radio Outfit Contest” shown in the December 1922 issue of Science and Invention magazine.

The self-explanatory set was designed by one George Goga, who took home a $25 prize for his entry. The magazine noted that almost all of the parts, with the exception of the headphone, could be found ayt no cost in the home junk box. A pencil forms the chassis. The eraser is removed and a galena crystal inserted in its place. The coil is wound along the pencil, with about 3/16″ of the insulation cleaned off so that the slider can contact the wire.

Mr. Goga reported that he lived several miles from station KDKA, and was able to pull in concerts clearly with a 50 foot long antenna 10 feet high.
