[Copied from rec.ham-radio on Usenet]
I am just starting to learn Morse code. I created the chart below to help
me visualize how the characters are related. It is a binary tree with
each branch indicating either "." or "-". You can use it to translate
Morse code to clear text as each "bit" (either "." or "-") is transmitted,
rather than accumulating the whole character and then searching for a match.
I feel that this is going to be a very natural way for me to memorize Morse.
Here's an example:
To find the clear text for "-.-.", start at the right branch (T) because
the first symbol is a "-". The next symbol is a ".", so travel down to
the left (N). The next symbol is a "-", so travel down to the right (K).
The next symbol is a ".", so travel down to the left (C). Since there
are no more symbols left, "C" is the clear text for "-.-.".
A percent symbol ("%") is used to indicate that no character exists for
the corresponding Morse (eg "..--"). It is only used when an existing
character is built up from said non-existing character (eg "..---").
Remember: if the symbol is ".", go left; if it is "-", go right.
If you find the chart a little hard to read on the screen, I suggest printing
it out in a monospace (ie non-proportional) font.
