I just spent the past five years learning Morse code, and for me it was significantly more difficult than learning a foreign language. Perhaps I'm just getting old and my brain isn't as pliable as it used to be, but it's been a very long and difficult journey. Here is what I've learned:

- You can memorize the letters and decode up to around 20 WPM. But this is using the low-bandwidth, logical part of the brain which simply isn't capable of decoding much beyond 20 WPM.

- To go beyond 20WPM you have to hand-off the processing to the subconscious mind. This is the phase that's equivalent to learning a new language. It requires a tremendous amount of repetition to build the mental muscle memory to hear the letters as a single sound instead of a series of beeps. It literally took years of daily practice to get there.

- Once you've mastered the individual letters you eventually start hearing combinations of letters as unique sounds. And at some point, you start to hear entire words, not letters.

- If I attempt to perceive individual letters at higher speeds I almost always end up missing the rest of the word. At these speeds, the conscious, logical brain becomes a liability that must be to be surpressed to decode effectively. As a 30 year software developer, this has been VERY difficult to do.

- When I get into the flow, I don't "think" about the letters or "hear" a series of beeps. The words somehow just magically pop into my mind.

You denied, then agreed :)

Morse code is not a new language, but it is a new way of writing, which is almost the same as a new language in many ways.

You get used to it, though. Your brain does the translating. I don't even see the code. All I see is blonde, brunette, redhead. Hey uh, you want a drink?

I learned Morse code almost 50 years ago. I distinctly remember how learning progressed through stages

- hear di-dah (sound), think dot-dash (printed symbols), in the table that's an A

- hear di-dah, think "A"

- hear dah, di-di-di-dit, dit, hear the word "the"

- add more and more words

Along with that progression, the mental buffer got bigger, as it has to in order for you to recognize whole words. If I was having a conversation near my speed limit, a good way to break me was to send a long unusual word

That isn’t what the person to whom you’re responding is saying.

Morse code is very much like a language in that there are audible intonations that differentiate between See, Aye and Tee. Being able to copy that in your head is the same as listening to English and not needing to reach for the dictionary every other word.
