That's not an ideal way to go. Morse is an aural language and needs to be learned by sound. Knowing what combinations of
'dots and dashes' compose various symbols is next to useless: A is didah, not "dot dash".
The optimal way to learn it is by having a partner or computer app transmit individual letters at relatively fast rates, so you don't have time to parse them into their elements. Then, adjust the transmission speed by varying the time between letters, gradually ramping things up as your recognition skills improve.
I can't debate you on that. I'm just reporting what I read in Harry Lorayne's book. And with one simple reading, and about 5 minutes of rehearsal, I knew all 26 letter translations.
But I never tried to convert it to use.
It seems on the internet, some who have learned Morse Code recommend techniques like this, while others recommend against mnemonic techniques.
Wikipedia has a few other examples of other mnemonic devices, so it seems that someone has found these techniques useful. And people learn differently.
If I compare it to learning a foreign language, I know my experience with that was that the hurdle of memorizing vocabulary was large, and memory techniques helped that. But it wasn't until I practiced, that I was able to "think" in the foreign language, and all intermediate steps went away. And books on memory book say that same thing.
