A hundred years ago this month, the October 1922 issue of Popular Mechanics showed this portable radio receiver suitable for Boy Scouts, campers, yachtsmen, or vacationists in general. The set was contained in a box measuring 6 by 6 by 3 inches, and featured a crystal detector tuneable between 100 and 600 meters (500 kHz through 3 MHz). It was said to be able to pull in stations 25-30 miles away, and included ground and antenna wires, as well as a ground stake. It could be set up in 15 minutes.
It was a product of the Bleh Co., Inc., of 53 Park Place, New York.
