MORSE-TELEGRAPHY

Samuel Finnley-Breeze Morse

The inventor of the Morse-Code

  Born April 27 in Charlestown, Massachusetts, 1791 - Died April 2, 1872 in New York


History

  In the year 1837

Samuel Finnley-Breeze Morse was an American inventor and professor of painting, sculpture, and drawing. In 1837, Morse developed the first usable writing telegraph (morse apparatus). Morse and his collaborator Alfred Vail also created an early character set, later known as Land Line or American Morse Code. Morse thus created the practical prerequisites for a reliable electric telegraphy, which was soon used.  (Text/pictures: Wikipedia) 

 

Morse code 1837 until today

No less than 6 versions preceded the current modern version changes in the representation of certain characters, but especially supplements depending on the application determined the composition of the alphabets. Virtually all signs have changed since the original version once or several times. 

  The first telegraph dispatch dated May 24, 1844

 May 24, 1844. The very first telegraphy-transmission at all: 

 "What hath God wrought" Successfully transmitted by wire from Washington to Baltimoore Station. See original paper stripe (detail) of the message. (image above)

The iMorsix Morse font Telegraphy

The Morse code set for amateur radio consists of 45 +1 characters.

The amateur Morse code set includes 45 +1 characters: 

Of course, the Morse Disease Character Set is included in iMorsix according to the table - since a short time with @ .

Morse code adjustments over time:

The fact that even in adverse circumstances with very little transmission energy to make large distances and reliably transmit messages has fascinated for 200 years!


WIRELESS TELEGRAPHY 

Guglielmo Marconi 

The inventor of the wireless telegraphy

Role model for all future telegraph operators: 

Never give up! 

Guglielmo Marconi

Born April 25, 1874 in Bologna, died July 20, 1937 in Rome

 Inventor of the "Wireless Telegraphy"

Marconi's first successful telegraphy-outdoor experiment:

May 13th, 1897, 60 years after the invention of the Morse Code, first successful outdoor attempt: the Morse code had traveled about 3 miles wirelessly between the English coast near Cardiff and the nearby island of "Flat Holmes" - a new record at the time.

The Morse signals between the English coast (Cardiff) and the island “Flat Holmes” had crossed 4 kilometers wirelessly, which was a new record! Two witnesses at that time were the English Post Minister and the German **electro-physicist Prof. Adolf Slavy, envoy of Kaiser Wilhelm’s II. 

**At the meeting at the time, Marconi could hardly hide his distrust... 

Was Slavy a spy?


The honor of Marconi in 1909: The Nobel Prize in Physics.
