American Morse vs International Morse - The Two-Code Story Old railroad men and radio operators could both be fluent in 'Morse' and unable to copy each other. For decades, two different codes shared one name. The American original The 1844 Vail code included letters with internal spaces and dashes of different lengths - musical, fast on a wire, but hard to copy by ear because similar letters differed only in timing inside the letter. The International fix Gerke's 1848 revision removed the internal spaces; the 1865 Paris conference adopted it globally, and wireless made it universal. American Morse held on in US railroad and landline work into the mid-twentieth century, then faded with the wires themselves.
