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.
