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
services, international broadcasters, radio amateurs, and others depend on this “refraction” and
return to earth of short wave signals for long distance communications around the globe. Still, it
is difficult to believe that you will be receiving signals from far off places with only a three
transistor radio. A regenerative high gain detector with two stages of equally high gain audio
amplification provides enough audio drive for either a crystal earphone or any audio power
amplifier. Have fun “DX-ing” – distancing around the world!
