VINTAGE VINTAGE RADIO valves and non military HAM RADIO apparatuses

The RADIO - in TRANSMISSION and in RECEPTION - is the signaling and communication technology using radio waves or electromagnetic waves generally with a frequency between 30 hertz (Hz) and 300 gigahertz (GHz). Radio (-communication) is certainly the first and greatest invention of the modern era and of the globalized world. The first actual experiments with electromagnetic waves in the direction that would later have been that of "radio transmissions" date back to between 1861 and 1872 with the two scientists Maxwell and Loomis. HERE OUR PROPOSAL!
