Telegraphy or CW as we often call it was invented by the artist Samuel Morse.
Samuel Morse (1791-1872)
The telegraph was the first means of communication via radio and is still very effective today in making contact with other radio amateurs all over the world.
In the past, there was a requirement for telegraphy knowledge to get your amateur radio certificate, which has not been the case since 1971.
Even though the requirement is no longer there today, I recommend everyone to learn cw.
For the beginner, there are some links below to use to train your ability to master the art of making connections using the telegraphy method.
Please visit the Radio School which is really good.
