I was a Radio/Electronics officer at sea for over twenty years. Initially I found learning morse code quite easy. Keeping it is harder, good way was to mentally convert text to morse when reading. Don't do it out loud or you'll have people moving away from you
There was a lot more to it as we had to also learn the morse for comma, fullstop, open & close brackets, hyphen, plus sign, end of work, all numbers plus a million and one Q codes.
Just the alphabet takes a few days to learn.. Simples
