Radio Society of Greater Bixby

We meet 2wice a month, 2nd and 4th Thursday, and as usual (April 9th) it’ll be at Scott’s hamburgers in downtown Bixby 7PM to 8:15PM. If you come a bit early you can get a great hamburger for dinner. After the initial Show & Tell of whatever people bring (last month it was a 1948 handy talkie – working) we’ll discuss 2 magnificent electronic designs, the five tube radio, and the single transistor TouchTone (reg PatOff) generator. Of course both designs grew from Lee DeForest’s Audion amplifying tube, the SuperHet radio receiver layout, and later, William Shockley’s 1947 transistor. Edwin Armstrong helped, but I’m not sure if General Robert Sarnoff was instrumental in anything other than buidling RCA.

Early radios by Bill Halligan like this Hallicrafters S38B had only five (5) tubes, just like the one in your mother’s kitchen. (My 1960 Hammarlund HQ145X had eleven (11) tubes, and was a better radio.)
