Of course the Americans have their own Morse code. Why wouldn’t the Americans have their own Morse code? (edit: instead of the International Morse Code that everyone else uses)

…because inventor Samuel Morse was american? Or is this a whoosh moment… I feel like I’m missing something…

This is different from the International Morse Code which the rest of the world uses. I actually didn’t even know about the American version up to now.

It’s not in modern use, it’s an artifact from before there was an international standard.
