The invention of the radio was a milestone in American history. For the first time we were able to listen to news around the world on a broad basis, not only that discussed in the local paper or communicated by way of the telephone or telegraph.

Most of us though, do not know how these signals can be broadcast and how they are able to appear in an incredible number of homes and on an incredible number of car radios simultaneously. In fact, we might are all aware much more about the way a computer works than how a radio works. In truth, that it would be a marvel of engineering at the time it had been created continues to be conveniently forgotten by the most of us taking it as a given. The majority of you haven’t known an existence without radio; actually a computer-less world is probably a vague memory to the majority of readers, though some may have fond memories of muscle-bound fingers gained while pounding away about the keys of those Remington manual typewriters.

Back to radios-the noise you hear coming out of the speakers on your radio would be the result of a transmission of signals by means of modulation. The signals are transmitted through the modulation of electromagnetic waves with frequencies below those of visible light. Basically, electromagnetic radiation is beamed through oscillating electromagnetic fields passing through the air and the vacuum of space. The radiated waves are modulated regarding amplitude, frequency, pulse width or phase, with an electrical conductor (radio stations) which transforms these signals into sound that carries information!

Okay, therefore the important thing isn’t to comprehend the way it happens, but what a fete it was to get it done in the first place. The invention of the radio resulted in communication and the dissemination of information in such a way regarding permit the common man, not only scientists and engineers, to hear world news. Developed during the same period of time as the telegraph and telephone, only the scientific community and explorers were in receipt of radio waves that allowed communication. Then came ham radio operators in the early 1900s, before invention from the Audion, the first radio tubes that allowed increased clarity and power. In 1920 Westinghouse partnered with Dr. Frank Conrad, a ham operator who often broadcast music for his friend’s and friends of friend’s enjoyment. On November 2, 1920, KDKA, out of Pittsburgh, broadcast the Harding-Cox presidential race and election results. The very first time, people ‘heard’ about this, instead of ‘reading’ about it within the newspaper, and the knowledge was instantaneous compared to the printed word.
