Morse Code Enters The 21st Century

N8TWJ writes "The International Telecommunications Union has decided to bring Morse Code into the 21st century by adding the loved (or hated?) - at (@) symbol. Lets hope the spammers don't start sniffing 20 meters for da-dit-da-dit-dah-dit..." According to the article, Paul Rinaldo, chief technical officer for the American Radio Relay League, says: "It's a pretty big deal... there certainly hasn't been any change [in Morse Code characters] since before World War II."

      By the way, and more seriously, people who do Morse code didn't wait for the ARRL to okay the use of this or that sign : a full international Morse code set with almost all ASCII signs, as well as regional sets, such as Russian and Japanese, have been around for quite some time now.

For us Hams, knowledge of it was also required for us to use any frequency below 30MHz. Since the ITU has eliminated it from the international treaties, most countries are eliminating it from their amateur radio requirements. The ARRL is also proposing a partial elimination of it for those of us in the US. It will be eliminated for every class of operation other than Extra (if the FCC approves it).

    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.

    It has to do with the relative length of time it takes to send morse characters. (Note in the following that "dahs" are three times as long as "dits".)

    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.

      Yes, "ES" is shorter than "AND", but if you look at an old chart of "American Morse," the precursor to International Morse, you'll find that there's a definition for "ampersand" that is ". ..." "dit di-di-dit".

      American Morse used brief spaces within symbols, something (wisely) dropped in the redesign for International 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".

      Even if you send sloppily, the best decoder in the world is the human brain, and it can pick out the meaning in a 30 words-a-minute conversation under difficult conditions where no other communication method can punch through.

      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.

    Back in the '60s or so, Irv Hoff (who later was instrumental in developing ham packet radio) was a radioteletype ham. 110-bps ASCII was around and in heavy use for landline teletype and those new-fangled minicomputers. But hams were still limited to 60-bps Baudot (5-bit) teletype and obsolete machines. (This was apparently because the FCC didn't have the budget for buying new moniitoring equipment, so it wouldn't legalize the new coding scheme and speed.)

    Irv wanted to go faster. Morse wasn't speed-limited and FSK modulation was allowed. So he built a couple copies of a device to convert ASCII to and from morse and send it either at 110 baud or (using tape) some truly hysterical speed.

    Of course the FCC heard the high-speed signals that they couldn't translate and came after him. And he said "But they're just morse! Tape them and slow them down and you'll hear it."

    So the FCC did. And shortly threw in the towel and legalized 110-baud ASCII.

    Which was the whole point of the exercise. B-)

    Now I think Irv may have came up with some arbitrary codings for the ASCII symbols that weren't part of Morse during that exercise. If so, and if they were easy for humans to use, it might have made sense to standardize those.
