Re: Why I'm Learning Morse Code

when i used to walk an hour to work (and another back), i considered using morse as an interface to a portable computer (for editing and playback of text). it's easy to hear and understand, even when there's considerable ambient noise, and data entry would only require a single button (plus perhaps a rocker switch or similar to scan through existing data). at the time i had no real idea how to implement it. now i thi…

I've also thought about a pocket-sized clicker device that you could use to send Morse to your friends, perhaps interfaced with your phone. Or maybe, as you said, you could use it as an input device. One day when I have some extra time on my hands I'm sure I'll sketch one out. But I've got to learn Morse first! ;)

I spent nine years as a naval communicator and am fluent in morse. It's been a few years so I would definitely need a bit of practice to get back up to 12 words a minute on a flashing light. I can speak three languages and morse was similar to learn. From the first day of training they gave us sheet of paper with the alphabet and the morse translation and told us to memorize a couple of letters. Then they sent us out…

More than a language, Morse is a script (or whatever is the generalisation of "script" to other transport layers than the written page), isn't it? The fact that you experienced learning Morse similar to learning a new language is rather surprising. For example, I would expect that you can transliterate random Morse into ASCII, perhaps at a lower bitrate, and, if so, the role of understanding the meaning of the content would be far less important than when learning a new language.

I love anecdotes like this. Were you taught Morse purely visually, with the flashing bulb? Do you find it easier to watch a bulb or to listen to a tone?

It was always visual. It seemed useless at the time, spending hours out in the pouring rain on a ship, sending a message with a flashing light to another ship, but they always reminded us that even with all our technology and cryptography, flashing light is still the most secure method of close ship-to-ship communications because it's directional when using focused light.

If any of you are already fluent in Morse, I'd love to hear from you! Were you able to hear full words or phrases "natively"? Did you ever have the experience of being able to identify the person on the other end merely by accent?

First I want to answer one of your other questions -- could a skilled Morse operator identify a person by his sending style, what we called his "fist". The answer is yes, absolutely. But there's more to it than that -- each CW (continuous wave) transmitter had different characteristics, in the days when most of them were built by their operators -- some of them changed frequency slightly during each dash, some of them had noticeable clicks caused by too fast a transmitter activation and deactivation around each Morse element -- these helped one identify a specific operator along with his personal sending style.

A few years ago, about the time that the FCC abandoned the code sending/receiving requirement, I assumed that CW was dead. But lately, listening to the ham bands, I see there's a surprising amount of CW activity still present.

> Were you able to hear full words or phrases "natively"?

Over time one begins to hear entire words, especially at high sending rates. This is especially true for common words, words that are part of every contact ... example "Name is (name)": "-. .- -- . .. ... .--. .- ..- .-.."

Here's a sample:

As this example MP3 shows, in modern times we can avoid the quirks of manual keying by letting a computer create perfectly shaped Morse characters for us. :)

Why I compare it to learning a new language is because after a certain speed it becomes almost impossible to read it out letter by letter. When you get good enough you start to see complete words in the light.

When you learn a new language you go through a stage where you're going back word for word to your own language in your head. Eventually you become good enough to start thinking in the new language.

I've been licensed as a ham radio operator since I was a kid (had an odd, early fascination with radio) and recently got back into it a few years ago.

I find using morse code extremely relaxing b/c it taxes your perceptual system in a way that is fairly uncommon in today's world. Either b/c it is being sent very fast or b/c of a weak signal and ionospheric noise, it's a "full brain" immersion exercise that leaves me feeling relaxed and contented (yes I know it sounds a bit odd).

I recommend it highly. Even for those not interested in radio, there are competitions for high speed morse (it's big in eastern Europe)... check out some of the training software:

and

Of course, real ham radio contests offer the best combo of adrenaline and strategy...

I learned morse at age 11 when I first got interested in ham radio. It took a couple of months of frequent use before it really felt natural, and this was probably about when I started perceiving words rather than characters.

It gets easier and easier the more you use it...

Thank you for this! It's so cool (and I'm glad you were able to confirm) that you can recognize an operator by his fist--just like a voice.

I had also read about each radio having its own quirks, but in my excitement forgot to include that in the article!
