LEARN MORSE CODE

Morse is just two sounds — a short dit and a long dah — arranged into letters. Here's everything you need to start sending.

Dots, dashes & timing

Every character is built from dots (•) and dashes (▬), and the whole system is measured against a single unit of time. A dot lasts 1 unit. A dash lasts 3 units. The gap between symbols inside a character is 1 unit, the gap between characters is 3 units, and the gap between words is 7 units. That is the entire specification. There is nothing else to know about the structure of the code.

Speed is nothing more than how long that unit lasts. The convention measures it against the word PARIS, which comes to exactly fifty units including the word space that follows it — so a station sending PARIS twenty times a minute is running twenty words per minute. That gives one formula worth remembering: unitMs = 1200 / wpm.

Work it through. At 20 WPM the unit is 60 milliseconds. A dot is 60 ms, a dash 180 ms, the gap inside a character 60 ms, the gap between characters 180 ms, and the gap between words 420 ms. Now key CQ. The letter C is ▬•▬• — dash, gap, dot, gap, dash, gap, dot, which is 3 + 1 + 1 + 1 + 3 + 1 + 1 = 11 units, or 660 ms. Q is ▬▬•▬ — 13 units, 780 ms. Add the three-unit gap between them and the call is 27 units: 1.62 seconds. Drop to 5 WPM and the unit stretches to 240 ms, so the same two letters take 6.48 seconds. The proportions never move. Only the clock does.

In Shortwave you don't measure any of this yourself. A quick tap registers as a dot, a longer hold as a dash, and a short pause commits the letter. But knowing the ratios matters, because every good practice method is built on deliberately breaking one of them.

Farnsworth spacing

The obvious way to make Morse easier for a beginner is to slow it down. It is also the wrong way. Slow the unit and you do not get an easier version of the same letter — you get a different sound. At 5 WPM•••▬ is four separate events with long silences between them, and the only way to identify it is to count. At 18 WPM it is a single rhythmic shape, di-di-di-dah, that you recognise the way you recognise a spoken syllable. Those are two different skills, and only one of them scales.

Farnsworth spacing is the fix. Characters are sent at full speed — 18 or 20 WPM, fast enough that each one has a rhythm — and the gaps between characters and words are stretched until the overall rate drops to something a beginner can follow. You might hear characters at 20 WPM with enough padding that the message crawls along at 8 WPM overall. The extra silence is thinking time, and thinking time is the one thing that should get shorter as you improve. When it does, you close the gaps and the characters are already at speed. Nothing has to be unlearned.

The Koch method

The other half of the method comes from Ludwig Koch, a German psychologist who worked on Morse training in the 1930s. His finding was that the usual approach — learn all forty-odd characters slowly, then try to speed up — produced operators who plateaued. His alternative was blunt: start at full target speed immediately, but with only two characters. Copy them until you are hitting 90 percent accuracy, then add a third. Copy again to 90 percent, add a fourth. The speed never changes. Only the alphabet grows.

It feels absurd for the first two sessions and then it starts working. You are never learning to recognise a sound and later learning to recognise it faster; you learn it once, at the speed you actually want. The 90 percent threshold matters too — move on at 70 percent and you carry the gaps forward and stall three characters later. The trainer on this site implements exactly this, and will not advance you until you clear the bar.

The usual opening pair is K and M, chosen because they are distinct from each other and neither is trivially short. If you would rather start somewhere gentler, the shortest and most common letters work too — E (•), T (▬), A(•▬), N (▬•), I (••) and M (▬▬). Whichever set you pick, name each character to yourself in sound rather than in symbols: di-dah for A, dah-di-di-dit for B, dah-di-dah-dit for C. The vowel change is not decoration — a dot at the end of a character is a dit and a dot in the middle is a di, which is exactly how the rhythm falls when it is keyed properly.

The mistakes that stall people

Most people who give up on Morse give up for one of five reasons, and all five are habits rather than talent.

Counting dots. If your internal process for H is "one, two, three, four dots," you have a hard ceiling somewhere around 10 WPM, because above that there is no time to count. The fix is to stop thinking in numbers and start thinking in rhythm: di-di-di-dit, one sound.

Visualising dots and dashes. Hearing the signal, picturing ▬••• on an imaginary page, and then reading that picture as B is a three-step process pretending to be one. Sound should map straight to letter with nothing in between.

Memorising the chart. The alphabet table further down this page is a reference, not a study aid. Learning it by sight builds a lookup table in your head, and a lookup table is precisely what you have to demolish later to get past 12 WPM.

Practising only sending. Sending is the easy half — you set the pace and you already know what the message says. Receiving is where the skill lives and where the bottleneck is. Copy far more than you send.

Stopping at 5 WPM. Five words per minute is slow enough to count, which means every hour spent there reinforces the habit that will stop you. Learn characters at 15 to 20 WPM from day one and use spacing, not speed, to control the difficulty.

A practice progression

Short and daily beats long and occasional, without exception. Fifteen to twenty minutes a day will take you further than two hours on a Sunday, because this is motor and auditory learning and it consolidates between sessions rather than during them.

Expect the first two characters to take a session or two. From there, most people add roughly one new character per one or two sessions, which puts the full twenty-six letters somewhere around six to ten weeks of daily work. Digits and the handful of punctuation marks that actually get used add another two or three weeks. That is the honest timeline for knowing the alphabet by ear, and it is the easy part.

The hard part is the stretch from about 10 WPM to about 20 WPM, where you stop decoding character by character and start hearing whole words. That takes months, not weeks, and it is where nearly everyone gets stuck. There is a whole dispatch on it: Breaking the 10 WPM Plateau. A realistic target for someone practising most days is a comfortable contact at 15 to 20 WPM within six months to a year. People who claim faster are usually counting only the good weeks.

Using this station

The console on the front page is a real key, not a keyboard shortcut. Hold SPACE, or press and hold the telegraph key with the mouse: a short press is a dot, a longer press a dash, and a beat of silence commits the buffer to a letter. The decoder tree traces your path in amber as you go, which makes the structure of the code visible — you can watch how •▬ and ▬• sit as mirror images two steps from the root.

Once the shapes are familiar, switch the receiver to EAR-COPY. The decoder goes dark, you still hear the signal, and the letters are yours to write down in the notepad. This is the drill that matters. A decoder that prints the answer for you will keep you at beginner level indefinitely, because your ear never has to commit. Wartime operators trained exactly this way, on paper, with nothing to check against until the message was done.

For structured work, the Morse trainer runs the Koch progression described above and scores each session. The Morse translator converts any text you paste into keyed audio at anything from 5 to 40 WPM, which makes it easy to build your own drills — a page of a book, a list of callsigns, the alphabet in a random order. The full chart covers punctuation and prosigns beyond the two tables below, and prosigns and abbreviations explains the run-together characters like CQ, SK and AR that you will hear on the air long before anyone spells anything out.
