Hog-Morse For instance, the international code has only two symbols, dots and dashes, but the American code has several lengths of dash. There is a distinction between "L" () and "T" (). Also, in the international code the space between symbols within a character is always the same, but American Morse has two different spaces. The letters "S" (), "C" (), and "R" () all consist of three dots, but the timing is different in each case. A frequently quoted, but possibly apocryphal, story from the historical period concerns the similarity of "L" and "T" in the American code. A company
Morse code This code was used since 1844 and became known as "Morse landline code" or "American Morse code". In the original Morse telegraphs, the receiver's armature made a clicking noise as it moved in and out of position to mark the paper tape. The telegraph operators soon learned that they could translate the clicks directly into dots and dashes, and write these down by hand, thus making the paper tape unnecessary. When Morse code was adapted to radio communication, the dots and dashes were sent as short and long tone pulses. It was later found that people become more proficient at
