The scouts shown above are taking a break from their campout to pull in some local broadcast stations on the two-tube superheterodyne receiver they constructing from the plans in the June 1949 issue of Popular Mechanics. The set used a 1R5 and a 1U5 tube and a 15 foot antenna to get good volume on the local stations. According to the magazine, the set rivaled any regenerative receiver, without the possibility of an annoying squeal.

According to the magazine, the rugged little set was ideal for camping or other knockabut use. It could be transported in a small cardboard container, or, if the builder preferred, in a cabinet.

The filaments ran off two flashlight batteries in parallel, with a 67.5 volt B battery.  For strong stations, a 45 volt battery could be substituted.
