The April 1950 issue of Radio Electronics carried the plans for this one-tube home broadcaster, dubbed the “Carry-Talkly” by author Otto Wooley, W0SGG. The microphone and chassis were easily sourced, since they were both war surplus, a Signal Corps BC-1366 jack box, and the T-17 microphone. The circuit used a 1R5 tube, and an 18-24 inch antenna provided a good signal around the house.

The author’s set was tuned to 550 kHz, although he pointed out that on a receiver with a high-gain IF stage, the broadcaster could be tuned to the intermediate frequency and be picked up regardless of the receiver’s dial position.
