The Transistor Museum™ Photo Gallery has been established to provide an easily accessible and informative repository of high quality photographs and detailed information about many of the unique and historic transistors, diodes and integrated circuits from the early days of this exciting technology. ELECTRONIC PROJECT KIT #28-110 THREE TRANSISTOR SHORT WAVE RADIO The air is literally full of radio signals from practically every country in the world. These “short wave” signals are propagated through space and refracted back to earth by the ionosphere to points many miles from the transmitter source. As a result, communications
