Is Morse code global?
The modern International Morse Code, introduced in the 1860s is
global. However its actual use is declining.
Morse's original code, introduced in the 1830s was mostly
limited to the US.
The European Morse Code, first introduced in Germany in the
1840s was mostly limited to Europe.
The International Morse Code was derived mostly from the
European Morse Code and is much simpler and easier to use than
Morse's original code.
