information sources and few examples of Eastern Bloc radios are to be found in the West, there is also an element of indifference here, perhaps partially fueled by a lingering prejudice best summed up by the 1960's American sentiment that 'the Russians can't even build a decent refrigerator....

Already in the 1920's, scientists understood how to make a two terminal device by making a point contact between a sharp metal tip and a piece of semiconductor crystal. These point-contact diodes were used to rectify signals, and make simple AM radio receivers (crystal radios). However, it...
It was obvious at the time that Bardeen and Brattain’s unwieldy contraption represented a breakthrough in electronics. But its inventors thought of it mainly as a replacement for vacuum tubes, which were used as amplifiers and switches in telephone equipment, radios, and most other electronic dev...

The first commercial applications for transistors were for hearing aids and “pocket” radios during the 1950s. With their small size and low power consumption, transistors were desirable substitutes for the vacuum tubes (known as “valves” in Great Britain) then used to amplify weak electrical ...
With this transistor radio, I can keep up with the weather and local news when I need to. I have also taken it with me sometimes when I am outside gardening and want to hear one of my favorite radio talk shows. I know with all the new electronic equipment that transistor radios are ...
The author looks at the common factor between the X-Gene microprocessor from Applied Micro and the 14-transistor radios launched by Korean manufacturers in the 1960s. He cites that Korean manufacturers added functionless transistors to their radios to differentiate themselves from those in Japan. He...
John Bardeen was an American physicist who was co-winner of the Nobel Prize for Physics in both 1956 and 1972. He shared the 1956 prize with William B. Shockley and Walter H. Brattain for their joint invention of the transistor. With Leon N. Cooper and J
