HOW TO BREAK THE 10-WORDS-PER-MINUTE CODE BARRIER
By Richard Humphrey
When this article was first published in 1974, the best Morse-Code-learning aids available to hams were the Instructograph paper-tape-based machine, phonograph records, and magnetic tapes (open-reel and cassette – I'm not aware of anything on 8-Track). Nowadays, we have software-based and standalone electronic aids, with more flexibility. Then, as now, the emphasis has been and is on hearing Morse characters' distinct audio patterns – not visualizing them as written marks – and instantly, subconsciously, copying those characters (whether by writing, typing, or “copying in [one's] head”). Regardless of when studied, there are some who reach a plateau while learning Morse Code, that sometimes takes a bit of perseverance to overcome. If this is you, don't give up – you'll get there. – MDB/N5RLR

Lucky is the radio amateur who doesn't "plateau out" somewhere around ten words-per-minute when he's learning code. There may be a fortunate few who march right up to 20 or 30 WPM without a break, but most of us make it to 10 WPM literally in a matter of days, then struggle for many months to get up to 15 WPM solid copy so we can be sure of hacking 13 WPM when we go up for our General. Once definitely past the 10-WPM "hump," progress is seldom a problem.
Hams aren't the only ones bothered by the CW plateau. The Navy, Army, Coast Guard, and Air Force all have their difficulties in getting their radio-operator trainees off the 10-WPM dime. When asked if the Army had a problem, Colonel A.J. Sullivan in Washington said:
"Yes we do. Approximately 60% of trainees reach a hump somewhere between 10 and 13 words-a-minute. Our goal is to raise them to 15," he said, "and often we're able to get them to go as high as 25 and 30 words-a-minute." Col. Sullivan went on to explain how the Army did it. "The first way is to have the student and instructor analyze error patterns and then determine remedial patterns to correct them in the student.
"The second way," he continued, "is to analyze individual rhythm patterns and make recommendations to improve these. The third thing is to try and get these students to copy 'behind' one or two characters so that they might be able to comprehend a whole word instead of a letter at a time."
A spokesman for the U.S. Navy, Lt. Tim Mennuti, echoed Col. Sullivan. "It takes three weeks to peak out," he said, "at which point the average person has reached 12 to 14 words-per-minute." Mennuti added, "The problem is that over 14 words-per-minute there are no breaks between letters." It appears the Navy considers the "hump" serious since we understand the training program is undergoing considerable revision.
Everyone interviewed agreed on one of two positions: either (a) the plateau was caused by reaching a speed where you had to stop copying letters and start copying words or (b) the "letter-to-word" transition was a coincidence and the reason for the "hump" had to be found elsewhere. The Navy seems to favor the latter view. "Apparently," said Mennuti, "there's some psychology connected with this thing that we didn't have before. What we're finding out," he explained, "is there may be a certain type of individual who can copy fast code and a certain type who can't."
Strangely, two things which might be expected to have had an effect on an almost auditory process such as learning CW seem not to have affected it at all: the increasing use of audio-visual aids in teaching and the tremendous impact of television on those who have been coming into the military. The generation which has been studying code for the past several years are, say the experts, "picture" oriented rather than "word" oriented. One might expect that hams and others cramming code today would be having more trouble. But Col. Sullivan says the percent of those hitting the "hump" hasn't changed "in the last 20 years."
Psychologists and authorities in the business of teaching brought up the point when they were interviewed that getting past the 10-WPM plateau wasn't a "learning" problem but a "fluency" problem. Obviously, they said, if you can copy and send ten words-a-minute, you know the code. The point was also made that gaining fluency in code might be similar to gaining fluency in a foreign language. If you learn a foreign language by "reading" it - in high school or college, for instance - you will usually have tremendous difficulty in speaking (or understanding) the language fluently. You will find that you translate from the foreign tongue into your own language, absorb the information, form an answer, in your own language, translate the answer into the foreign language, and then say it. To gain any fluency whatsoever you must think in the foreign language.
But how do you "think in code?"
Here, the experts and authorities as well as military instructors and radio amateurs are more-or-less in agreement. Number one on everyone's bugaboo list: don't sit down and learn the code before you start listening to it! Many hams fall into this bottomless pit. The CW trainee in the military has usually been sitting there for three hours with the cans on his head listening to taped copy before someone tells him what it is he's doing. Even so, six out of ten plateau out somewhere around 10 WPM, according to the Army. The attrition rate among radio amateurs must be tremendous. One instructor put the problem this way:
"When you find yourself hearing dah-dit-dah-dit and saying 'Aha, that's a C' and then writing it down, you're in big trouble. It's got to be instantaneous," he said. "You hear it, you write it. No translating!"
The way you transcribe CW may also have a direct bearing on the 10-WPM hump. Without exception, everybody agrees that the best way is to use a typewriter. For two reasons. First, the mental attitude you have when you learn to touch type is quite similar to what it should be in learning code. You're not translating. You learn by rote that the right forefinger goes there and the left forefinger goes here for this letter or that letter. You're not falling into the bad habit of reading a letter, looking for it on the keyboard, then hitting it.
Second, copying by hand in capitals will limit your speed to around 15 WPM. Long-hand script will only take you to 25 WPM or so. The only thing limiting your code speed when using touch typing is your typing speed. A 40-WPM typing speed in only fair. A 40-WPM speed in copying code is very good. (It's undoubtedly no coincidence that of the Air Force's 630 hour CW course, 435 hours are devoted to "touch typing and transcribing International Morse code with a typewriter.")
The various tapes and records on the market to teach you the code undoubtedly have some value. The unanimous comment from radio amateurs is that they'll memorize each tape or record after a few playings and once this has happened the recording is useless. Tapes work out fine for the military because they can afford thousands-of-hours of it so there's little chance of copy memorization. Hams usually aren't so affluent.
What to do if you "studied" the code before you began listening to it? You can try the Army's recommendation of "copying behind" to try to progress from letter copying to word copying. Or you can try the method used by a former Navy Chief Radio Electrician.
"My hump was around nine-a-minute," he says. "It made me mad. I just kept at it. I copied until my eyes fell out. I even copied Russian and Spanish code, though I didn't understand it. Later, aboard ship, they tested me on taped copy and I made 9 words-a-minute.”
To many would-be hams, all this insistence on an "antiquated" form of communications is ridiculous. With FM, SSB, facsimile, and other things to come in the future, they may be right. But CW is still the simplest form of long-range communications. Because when you are using CW, you can cut through QRM with modest power, a minimum number of components with simple antenna, and troubleshooting and repairs can be made with almost no training. CW is a unique case of the Old Gray Mare being just as good as she "used to be."
