Morse Code, Radio & Satellite Communications

The technology of communications has evolved during the past two centuries from crude and limited mechanical devices capable of reaching only short distances to highly sophisticated media capable of reaching around the world and into space. Our present-day complex technology would never have been possible without the progression of smaller discoveries and inventions that led up to it.

One of the early communication systems that broke ground for future innovations was Morse Code. In 1835, Samuel Morse developed a primitive relay system, the first telegraph, along with an associated vocabulary of dots and dashes(the Morse Code(that could be transmitted to send complete messages. However, he soon developed an improved version that included pauses, the American Morse Code, in conjunction with Albert Vail. The various combinations of dots, dashes, and pauses represented letters, numbers, punctuation, and symbols and could be transmitted either by audio tone or radio signal. The code was eventually refined again with the pauses eliminated to become the International Morse Code. Meanwhile, the technology of the telegraph was improving year by year as well, until telegraph transmissions became lightning-fast and multiple messages could be sent over the wires at the same time.

The advantages of Morse Code for communications needs were legion, especially during war. Compared with couriers(previously the only way to get important m

-wave link being established between London and Birmingham, England. The Westinghouse Company set the next big milestone by building a 100-watt radio station on top of its Pittsburgh factory. Radio had been born. Radio transformed communications in its day and initiated the concept of receiving entertainment in oneÆs home. It also spawned a new entertainment genre(the radio serial. Programs such as ôFibber McGee and Mollyö and ôThe Shadowö drew faithful crowds of listeners who would do anything rather than miss their favorite show. At the appointed hour, families would gather around the radio, which in those days was often a large console model, and listen in breathless silence to the unfolding of the plot. Cliffhangers were a common device for maintaining an avid listening audience, and listeners debated the possible plot outcomes until the following broadcast revealed the resolution. In the pre-television era, radio was the entertainment format that reached the mass media, and news communicated by radio reached people quickly. The gap between the advent of radio and the establishment of satellite communications in the 1960Æs was a large one, and television and various other technologies were introduced in the interim. H
