Rai Internazionale Radio has been broadcasting from Rome to the rest of the world for the past 72 years under various names. In the 1930s Italy was one of the first countries to begin international shortwave broadcasts. Guglielmo Marconi, the man who invented radio, oversaw the construction of the first short-wave transmitter at Prato Smeraldo outside Rome on July 1, 1930. Four

text: Invented tradition The invention of tradition is a concept made prominent in the eponymous 1983 book edited by British Marxist intellectual E. J. Hobsbawm and T. O. Ranger. In their Introduction the editors argue that many "traditions" which "appear or claim to be old are often quite recent in origin and sometimes invented." They distinguish the "invention" of traditions in this sense from "starting" or "initiating" a tradition which does not then claim to be old. The phenomenon is particularly clear in the modern development of the nation and of nationalism, creating a national identity promoting national unity, and legitimising

The coherer was a glass tube with metal electrodes at each end, with loose metal powder between the electrodes. It initially had a high resistance. When a radio frequency voltage was applied to the electrodes, its resistance dropped and it conducted electricity. In the receiver the coherer was connected directly between the antenna and ground. In addition to the antenna, the coherer was connected in a

The first person to use radio waves for "communication" was Guglielmo Marconi. Marconi invented little himself, but he was first to believe that radio could be a practical communication medium, and singlehandedly developed the first wireless telegraphy systems, transmitters and receivers, beginning in 1894-5, mainly by improving technology invented by others.

A few receive shortwave bands, but strong signals are required. The first crystal sets received wireless telegraphy signals broadcast by spark-gap transmitters at frequencies as low as 20 kHz.

This consisted of a huge rotating electromechanical AC generator (alternator) turned by an electric motor at a fast enough speed that it generated radio frequency alternating current, which was applied to the antenna.

In 1916 it became the first radio station employing a vacuum-tube transmitter to make news and entertainment broadcasts on a regular schedule, and, on November 7, 1916, became the first to broadcast U.S. presidential election returns by spoken word instead of Morse code. Initially all radio stations used spark transmitters, which could only transmit Morse code messages. In 1904, Valdemar Poulsen invented an "arc-transmitter" capable

Edwin Howard Armstrong invented the superheterodyne receiver in 1918. Armstrong and RCA (under David Sarnoff) had a business and technical relationship, that would last into the 1940s. Funded by RCA, Armstrong designed a radio that can receive stations easily without complex tuning or interference from other stations. Early radio designs by Armstrong and others produced radios that were very sensitive but hard to

Another implication is that the concept of "authenticity" is also to be questioned.

The major radio receiver designs, listed below, were invented during the vacuum tube era. A defect in many early vacuum tube receivers was that the amplifying stages could oscillate, act as an oscillator, producing unwanted radio frequency alternating currents. These parasitic oscillations mixed with the carrier of the radio signal in the detector tube, producing audible beat notes (heterodynes); annoying whistles, moans, and howls in the speaker. The oscillations were caused by feedback in the amplifiers;

The superheterodyne receiver, invented in 1918 by Edwin Armstrong is the design used in almost all modern receivers except a few specialized applications.
