Morse: translate, listen and train
Morse is learned by ear, not by memorizing dots and dashes. That is why the training here plays each letter at final speed and adds more space between them (Farnsworth) while you catch the rhythm. The speed reference is the word PARIS: 50 units, so a dot lasts 1,200 / WPM milliseconds.
