    <<What if we rearranged the codes? Then we would get 4.1257 which would be about 9% more efficient. To put it another way, Morse code achieved 91% of the efficiency that it could have achieved with the same codes. This is relative to Google’s English corpus. A different corpus would give slightly different results.>>

    What it doesn't take into consideration is common abbreviations in CW, like Q signals.

    I hardly ever have any morse leftover from a QSO session. The small bits that remain as build up on the key are easily dusted into an ashtray. Mind you, I do wash my hands when I'm done. Yes, very efficient indeed! ;)

    You're lucky.

    I always have a dit left over. I call it the "hanging dit."

    I just spent 5 minutes on this thread...least efficient thing I did all day.

    So based on Google's English letter frequency, 29.81% of the time we EAT?

    That explains a lot!! ;)

    Friendly definition clarification for those new to Continuous Wave and also Morse code.
    We Learn Morse.
    We work CW.
    Glad to find you're interested in Morse code enough to want to apply your efforts to learn it.
    Welcome and Best Regards.

    We probably all know this but I believe Mr. Morse is said to have visited the local newspaper and counted the type drawers see how many of each letter were kept on hand. Using this analog for the frequency of use, he assigned the code characters. According to this book on information theory, morse code is described as a four character cipher ( dot, dash, short space, long space). As I am lucky to reach 10wpm, I personally don't worry about efficency.

    But all this is fine if English is used. But for the majority of countries and speakers of other languages this doesn't work out.
