Morse Code (Edited from Wikipedia)
Morse Code (Edited from Wikipedia) SUMMARY Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. It is named for Samuel F. B. Morse, an inventor of the telegraph. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns) as standardized sequences of short and long signals called "dots" and "dashes", or "dits" and "dahs", as in amateur radio practice. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages. Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission. To increase the speed of the communication, the code was designed so that the length of each character in Morse is shorter the more frequently it is used in the language. Thus the most common letter in English, the letter "E", has the shortest code, a single dot. -

Morse Code and the Information Age Morse Code, Invented by Samuel F. B. Morse in the 1830S, Is a Method of Transmitting Textual
Morse Code and the Information Age Morse code, invented by Samuel F. B. Morse in the 1830s, is a method of transmitting textual information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the Roman alphabet, the Arabic numerals and a small set of punctuation and procedural signals. The original telegraph system had an apparatus on the receiving end that spat out a string of paper with indentations on it. Short indentations were called “dots” or “dits,” and the longer ones “dashes” or “dahs.” Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages. Morse code has been in use for more than 160 years—longer than any other electrical coding system. What is called Morse code today is actually somewhat different from what was originally developed. The Modern International Morse code, or continental code, was created by Friedrich Clemens Gerke in 1848 and initially used for telegraphy between Hamburg and Cuxhaven in Germany. Gerke changed nearly half of the alphabet and all of the numerals resulting substantially in the modern form of the code. After some minor changes, International Morse Code was standardized at the International Telegraphy Congress in 1865 in Paris, and was later made the standard by the International Telecommunication Union (ITU). Samuel Morse's original code specification, largely limited to use in the United States and Canada, became known as American Morse code or railroad code. -

' «i -•aif -ISe • 1-b Publication of the Letter DEPARTMENT OF COM'lERCE Circular BUREAU OF STANDARDS LC 45 WASHINGTON, D. 0. CONSTRUCTION AND OPERATION OF A SIMPLE RAD IOTELEGP.APHI C CODE PRACTICE SET.* (Prepared at request of the States Relations Service, United States Department of Agriculture for use by Boys 1 and Girls 1 Radio Clubs.) Introduction This pamphlet describes apparatus which may be used for the pur- pose of learning the radio telegraph code. The apparatus is very easy to set up and operate. It is intended to be used at radio club meet- ing places or in places where a number of radio students are accustomed to assemble. Those who construct the simple radio receiving sets des- cribed in the first two pamphlets of this series will probably hear many signals which are in code. The Code Practice Set is therefore made a part of this series so shat the international Morse Code may be learned. The cost of the complete outfit will be about $5*70 or, if one constructs the telegraph key, she. cost will be reduced to about $3«b0 It is assumed that those who use this outfit have radio receiving sets and can bring their telephone receivers (“phones") to connect to the other apparatus. It is also assumed that it will not be necessary to purchase the table upon which the parts are mounted. It is desirable *This is the third of a series of pamphlets describing the construction of radio equipment. The two publications which nave been issued are Letter Receiving Circular 43 , "Construction and Opera-cion of a Very Simple Radio Equipment," and Letter Circular 44, "Construction and Operation of a Two- Circuit Radio Receiving Equipment with Crystal Detector." These describe the construction and operation of simple receiving sets. -

Despite being monotonic and irregular, good Morse has a curiously musical quality, far from monotonous. However, on the air we typically face QRM, QRN, QSB, weak/marginal signals leading to errors and gaps in the copy, confusion, fatigue and frustration. Throw in badly-sent CW such as mis-sent characters, uncorrected errors, spelling mistakes, stray dits and missing dahs, variable timing with seemingly random spacing, plus off-frequency transmitters, drift, chirp, ringing filters and so on, and making contact may become, let’s say, challenging.

Morse Code - Wikipedia, the Free Encyclopedia File:///H:/Optical/Morse Code.Htm
Morse Code - Wikipedia, the free encyclopedia file:///H:/optical/Morse_Code.htm Morse Code From Wikipedia, the free encyclopedia. Morse Code is a method for transmitting information, using standardized sequences of short and long marks or pulses -- commonly known as "dots and dashes" -- for the letters, numerals and special characters of a message. Originally created for Samuel Morse's electric telegraph in the mid-1830s, it was also extensively used for early radio communication beginning in the 1890s. However, with the development of more advanced communications technologies, the use of Morse Code is now largely obsolete, although it is still employed for a few specialized purposes, including navigational radio beacons, and by CW (continuous wave) amateur radio operators. Morse Code can be transmitted in a number of ways: originally as electrical pulses along a telegraph wire, but also as an audio tone, as a radio signal with short and long pulses or tones, or as a mechanical or visual signal (e.g. a flashing light). Because Morse Code is transmitted using just two states -- on and off -- it was an early form of a digital code. International Morse Code is composed of six elements: 1. short mark or dot (·) 2. longer mark or dash (-) 3. intra-character gap (between the dots and dashes in a character) 4. short gap (between letters) 5. medium gap (between words) 6. long gap (between sentences) However, the variable length of the Morse characters made it hard to adapt to automated communication, so it was largely replaced by more standardized formats, including the Baudot code and ASCII. -
A Little More About and Around the Morse Code
1 A LITTLE MORE ABOUT AND AROUND THE MORSE CODE Featuring Samuel Finley Breese MORSE (left), Alfred VAIL (middle) and… Friedrich Clemens GERKE (right) 1. Shall we say the Morse code, or should we call it the Vail code? And where does Gerke comes in? (see point 2). A controversy exists over the role of each in the invention of the code. Vail and Morse certainly collaborated in the invention of the Morse telegraph and almost certainly in the final form of the code. But it is clear that the basic ideas came from Morse, years before Vail became, in 1837, his assistant. So, perhaps we should say that Morse was the inspirer, and Vail the man who brought out their final version. Here are some observations in this regard. > During his voyage home to New York in 1832 on the Sully, Samuel Morse first conceived the idea of the electromagnetic telegraph during his conversations with another passenger, Dr Charles T. Jackson of Boston, a twenty-eight-year-old physician with a Harvard M.D. Below you see the reproduction of some drawings in Morse’s notebook, in which he has noted down during this voyage some of his first ideas about a telegraph machine. He originally devised a cipher code (digits 0…9), similar to that used in existing semaphore line telegraphs, by which words were assigned three- or four-digit numbers and entered into a codebook. The sending operator converted words to these number groups and the receiving operator converted them back to words using this codebook. Morse spent several months compiling this code dictionary. -
Milestones in Telegraphic History Robert Jones, W5TU
Milestones in Telegraphic History Based on a chronology developed by Robert Jones, W5TU Richardson, TX And As Published in DOTS and DASHES, Volume XV Nos. 1-4, 1987 1753 Charles Morrison, in Europe, proposes an electrostatic telegraph system in which the use of 26 insulated wires conducting charges from a Leyden jar cause movements in small pieces of paper on which each letter of the alphabet is written. 1763 Bosolus describes a system similar to Morrison's except he uses only two wires, and a letter code. 1791 Apr. 27 – Samuel Finley Breese Morse born in Charlestown, Mass. 1797–1838 Many advances are made in the theory of telegraphy. Contributors include Lomond, Reiser, Salva, Cavallo, Ronalds, Sommering, Schweigger, Coxe, LaPlace, Triboaillet, Schilling, Henry, Gauss, Weber, Steinheil, Clarke, Masson, Breguet, Davy, Deval, Billon, Soudalot, Vorsselman and many others. 1797 Lomond, in Europe, proposes a system similar to Morrison's except it uses a single wire and alphabet in motion. 1799 Volta, in Italy, develops the "Voltaic Pile," or battery. 1810–1815 Morse, 19 years old, has become a painter and graduates from Yale College. He studies in England and has works exhibited at the Royal Academy. At 24 he returns to America and takes up portraiture as a profession. 1816 Ronalds, in England, demonstrates his electrostatic telegraph which is similar to Morrison's proposal, except pith balls are deflected by the charges. The system uses only two wires. A pair of synchronous clockwork dials, one on each end, are used to identify letters. 1820 Oersted discovers that electric current along a wire causes a compass needle to turn. -
