Reason for odd-looking morse words (Score:4, Informative)
For example, "AND" is di-dah dah-dit dah-di-dit, while "ES" is dit di-di-dit. "AND" takes more than three times as long to send as "ES", so "ES" has become popular. Similar logic leads to the use of "FB" over "OK", although both are heard.
The letter "O", dah-dah-dah, is particularly troublesome, since it is a popular vowel in English, yet it is very long; other letters are often substituted for it when possible. On the other hand, "E", dit, is the shortest letter; it is often used to to substitute for other vowels. "FER" for "FOR" is the result.

World Wide Morse Conference in Oxford
By Harold Banfry in Oxford
Filed 19 February 2004
World Wide Morse Consortium begins a week-long meeting today in Oxford. The distinguished but beleagurered coterie of academics from around the world will discuss the apparently dim future of Morse, its public perception, and paths for its future.
One of the most exciting developments planned for Spring 2005 is the roll-out of Morse Unicode, to accommodate the requirements of the international developer community. Each dot ("dit") or dash ("dah") in the previous scheme will be replaced with four dots or dashes.
"This enhancement is long overdue," says Dr. Davit Dannaugh. "Now we can represent any letter uniquely in any language. With the increasing availability of dedicated broadband Morse lines, there will be no practical impediments."
Also in the limelight for the Oxford meeting are Morse cryptography, Morse security, and Voice over Morse.

Second: it's inefficient. It's a binary code (dit and da) and yet it's redundant. The Shannon entropy for English is lower than the calculated average message length for Morse. They should be using a Huffman code.
Suggestion: Create a Huffman code from well-known English letter frequencies. When constructing this code, always put the more-common subtree on the left side of the new Huffman node. Then, when translating to das and dits, always use dit for a left-going branch and da for a right-going branch (dit = 0, da = 1). This accounts for the fact that the "da" symbol takes longer to transmit than "dit".
The result won't be Morse code, but we could name it something else... "Huffman-Morsoid," or say, "Horse code."

I can't speak to its efficiency or lack thereof, but are you aware that Morse did take into account usage frequency when designing the code? The shortest letters are the ones he thought, based on the research he had available at the time, were the most frequently occuring in English, "E" and "T" which are one symbol each (dot, and dash). He made an attempt to follow that plan for the rest of the code as well.
So it's flawed, I grant that. But it's worked pretty darn well for approximately a hundred and fifty years. Saved a few lives. Would have saved many of the souls on the Titantic if it hadn't been for human stupidity.
