"How did you learn the Morse Code?" ...
Ask a local flying school if they've got the contact details of someone who runs Morse Code "classes". Don't be surprised, someone may still run classes. If not, google it.
I went for one such class just to get me going and then finished it off myself with the "audio cassette" the instructor sold me. Had to pass the test at 7 words/minute.
Listened to that tape in my car everywhere I went (needed to have a pass in that fairly quickly back then), and even cut out the Morse Code from a Jepessen Chart and stuck it to my steering wheel.
Even ended up doing what Cesco did while driving... alphabets AND numbers, tho the test had just alphabets and groups of 5 letter words at random (that actually meant/spelt-out nothing.... eg.: GILPT, ARXUN etc.)
You'll get there. Good luck!
