Transistor-based Audion radio for shortwave reception
Shortwave radio, in the frequency range of 3 to 30 MHz (100 to 10 m wavelength), has lost popularity with the advent of the modern digital communication means, which are much more powerful as to the available information-carrying capacity. Nevertheless, shortwave radio has an unbeatable advantage over Internet & Co, in that it does not depend on external network resources. Shortwave radio enables global, direct point-to-point communication, which remains available when everything else fails. This is the principal reason why shortwave radio is still appreciated and used today for communication…
