SPORTS RADIO is Combination Cane and Seat
By FRANK TOBIN CONSISTING of a compact yet powerful battery receiver mounted on a conventional cane-seat which can be purchased for a dollar or two, the radio illustrated forms a handy set for hikers, sports spectators, and campers. The circuit, designed around three of the new American-made midget tubes, consists of a pentode regenerative detector, resistance coupled to a pentode amplifier which in turn is resistance coupled to a second audio-amplifier stage. Regeneration is controlled by a 25,000-ohm potentiometer. Since the commercial type of antenna coil shown in the diagram has no tickler winding it will be necessary to provide one by winding approximately thirty-five turns of No. 38 double-silk-covered wire around the lower end of the long, flat grid coil.
