    Obviously, morse code operators have had ways of getting around using 'at' signs for almost two hundred years, but it's a cool addition, and is as big a deal as they make out.

    I find morse code interesting because so many old timers complain about how the Internet makes 'ppl tlk lk this' and say 'nce 2 c u l8r', but that sort of abbreviation has been used in Morse Code for decades! The typical banter you see on IRC or in SMS cellphone text messages is pretty tame compared to what those operators could pump out on the wires :-) If any Morse operators here have some good examples, do post!

      Odd thing, I could only understand this by di-dahing quietly under my breath.

      When I was first learning code (mid 1970's) I had an ARRL practice tape. It introduced a few letters, had some practice, introduced some more letters etc.

      My father had been a US Navy communications officer in WWII, but left radio behind at the end of the war. He went straight thru the tape making extremly minimal errors. He was doing better after 30 years of not practicing than I was doing after hours of practicing.

      It was never declared obsolete... It was just eliminated from the ITU rules for maritime radiotelephone operators. 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).

      No, the inter-symbol pause really doesn't take that much time. It actually takes only marginally longer than the pause between dots/dashes, because once you get to real morse speeds (>100 cpm) you don't really listen to the signs, you listen for the "rhythm". However, what does take long, is the pause between words, that you have to leave to make the letters a and t stand out as a word, especially since they are both so short. So all and all, this will speed things quite a lot.

      Morse code is the primary communication method during harsh conditions. From the 12 months I was in the navy, about 4 we practised morse code. The same goes for national emergencies, when cell phone networks and other electrical communications networks would be down.

      Even in extremely bad radio wheather, and when all other communications networks are down, morse code is audible behind all the hiss and crackle (with good equipment).

      Here in Finland, where extreme distances are a problem (our country is twice as big as England with a population of 6 million) radio amateurs have arranged a peer-to-peer network for emergencies. They have a yearly test of the network. Basically even the authorities have to trust this voluntary network when a bigger chrisis occurs.

    Morse code is an early variable-length data compression stanard (similar to Huffman [wikipedia.org] codes or Shannon-Fano [wikipedia.org] codes). By representing common letters [askoxford.com] with shorter codes ("E = "," and "T" = "-") and rare letters with longer codes ("Z" = "--.." an "Q" = "--.-"), Morse code manages to encode the 26 letters of the alphabet in 4 bits maximum and much less than 4 bits per letter on average.

    Although Morse did use letter frequencies in constructing his code, it is not a truely optimized code, from what I can tell. Numbers are encoded with a cumbersome 5 bits per digit. Also, the transmission time of messages might be further reduced with minor rearrangements of the code to use more dots (short transmission time) in more frequent letters and more dashes (long transmission time) in the less frequent letters.

    I have to ask: with so many thousands of glyphs in Chinese, what did they do to utilize telegraph lines when that was the only means for fast long distance communication?

    I'm assuming they didn't create a different sequence for each one....

    • AFAIR, they converted each glyph to a number, and then sendt the nunmbers. I seem to recall hearing that it was a four digit number, but I'm not certain.

    • I would guess (wildly) that by the time there were telegraphs in wide use in china, there already was a method of writing chinese words in latin alphabet.

      Like, you know, writing "Beijing" instead of "$@".

      There's a big codebook. The basic book uses 4-digit groups (page-page-row-col) plus some extensions. It's often referred to as Chinese STC (Standard Telegraphic Code).

      There's an apocryphal story among cryptologists about a British missionary who emerged one day after a long stay in the backcountry, announcing triumphantly that he had broken the Chinese telegraphic code...

    Some ham operators wouldn't mind more changes to spice up the language. While Morse code has a period, a question mark, and even a semicolon, it offers no simple way to articulate excitement. "I was hoping they'd add a character for the exclamation point," said Yocanovich....

    Which leads me to wonder: how many emoticons can you express in Morse Code? Or do they have their own equivalent already?

    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.

    First: it's ambiguous. You can interpret a particular series of da/dit in multiple ways. Sure, a human can figure out from context, but what about a computer?

    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."

      Morse is not ambiguous unless you have a sloppy fist. There's rules for the length of a dash vs. that of a dot at any sending speed (I forget-- 1.5 times? 3 times? Can't remember) so that it scales up and down. If you send carefully a program in a PIC using a few K of code can decode you reliably.

      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.
