Morse Code is comprised of two different signal units—dots and dashes. Your first objective will be learning to recognize these units as they appear in text. Dots look like simple periods, whereas dashes are long horizontal lines similar to hyphens. Every character in the English language can be represented using these two signals.
-In the official terminology of Morse Code, dots are called “dits,” pronounced with a short “i” sound and a silent “t.”
-Dashes are formally known as “dahs,” with a short “a” sound.
Scan the Morse Code alphabet and refer to it when attempting to decipher single characters. As you go through the alphabet, make a note of each individual letter or numeral, then recite its corresponding dit-dah combination out loud. With time, you’ll be able to recall bits of code reflexively based on both their sound and appearance.
-Though the Morse Code alphabet is a helpful resource, most accomplished users recommend learning the system by its sounds rather than the way it's represented in text. This greatly simplifies the process by getting rid of the extra step of referencing the way the signals look when written out.
-A downloadable reproduction of the Morse Code alphabet can also be found at the bottom of this article.
Practice saying dits and dahs aloud in the correct rhythm. Dits make a short, single-syllable sound. Dahs are more drawn out, and should last approximately three times as long as dits when pronounced. This fast and slow rhythm is how individual units are distinguished in Morse Code.
-Pay attention to the spacing between words and letters. Each letter should be separated by a space equal to one dash, while complete words should be separated by the space of seven dots. The more meticulous your spacing is, the more likely it is that your message will be understood.
-It is generally faster to learn Morse Code by sound rather than sight, since it allows you to forego the process of counting up dits and dahs.[5]
Word association can be a valuable tool in helping you keep track of letters and numerals in Morse Code. For instance, you could link the letter “C” in your memory to the word “catastrophic,” which begins with a “C”, contains the same number of syllables and even has the same syllabic emphasis. Other examples include “mailman” for “M” and “gingerbread” for “G.”
-Devise your own word associations that will help link sequences of signals with their related sounds naturally in your mind.
-Jot down a few word associations in a notebook and study them while getting the hang of reciting each letter out loud.
The simplest letters to begin with are the ones that are represented by a single dit or dah. One dit, for instance, makes the letter “E,” while one dah makes “T.” From there, you can move on to two dits (“I”) and two dahs (“M”) and so on. Solidify your knowledge of elementary characters before putting together more complex sequences.
Two and three letter words ("me" = - - . ) ("cat" = -.-. .- - ) will be easiest to commit to memory when you’re first getting a feel for the format.
-The sequence for the distress call “SOS” ( . . . - - - . . . ) should be one of the first things you learn, as it could potentially save your life in an emergency situation.
Look up recordings of Morse Code messages that will give you a sense of how communication is carried out using the system. Pay attention to the pauses between each character as well as the characters themselves. If need be, slow the playback of the recording to make each signal easier to pick out.
-An extensive collection of Morse Code recordings are available for listening practice in the archives of the American Radio Relay League.
-If you own a ham radio, tune into HF frequencies to get a taste of the real thing.
-Purchase practice recordings to receive instruction that’s tailored to your comprehension level. "Morse Code Teacher" by Gordon West is a good place to start.
Children’s storybooks are full of terse, simple language that are perfect for practicing Morse Code as a beginner. Go through the books page-by-page, translating the brief sentences into code. The system was designed to convey uncomplicated messages, so as a training exercise these types of books can come in handy.
-When you’re just getting started, use books aimed at first time readers, such as “Fun with Dick and Jane.” These books are known for their famously simple sentences ("See Spot run. Run, Spot, run!" = ... . . ... .--. --- - .-. ..- -. .-.-.- .-. ..- -. --..-- ... .--. --- - --..-- .-. ..- -. )
This is a useful strategy for helping you meet speed goals. For instance, if you’re attempting to copy five words per minute and there’s about ten words on each page, you should strive to complete each page in roughly two minutes
End a study session by copying out a few random words and phrases, then jumble them up and translate them at the beginning of the next session. This will help reinforce your knowledge by allowing you to see and interpret the same characters repeatedly. Keep your vocabulary simple to make writing and reading messages more efficient.
-After you become more competent, keep a journal exclusively in Morse Code.
-For regular practice, get in the habit of copying out your grocery list, the names of your loved ones, haikus or other short messages.
If you know someone else who is making an effort to learn Morse Code, the two of you can improve your skills together. Use code to greet one another, communicate ideas or tell dirty jokes in secret. You’re much more likely to learn if you have another person to keep you motivated and make things fun.
-Make a set of flashcards and have a friend or loved one quiz you.
-Send text messages in dots and dashes instead of your ordinary language.
Nowadays, there are apps like Morse-It and Dah Dit available that can give you the chance to study. These apps are part visual recognition and part audio recording, providing a more integrated learning experience. They also allow you to interact directly with the push of a button using your device’s haptic touch response, which is much more like the traditional way of tapping out Morse Code messages..
-Using an app will enable you to practice at your own leisure at home or on the go.
-Combine app-based study with pen-and-paper practice to reinforce your code comprehension in all its different forms.

AARS amateur radio clubs hold courses on Morse Code. These courses are generally open to anyone, regardless of whether or not you’re ham radio enthusiast. In a traditional classroom setting, you’ll have the benefit of organized lesson plans and one-on-one instruction that can greatly enhance your ability to learn.Please contact VU3MOE for futher details.
-Instructors are qualified to present various methods that are effective for teaching different types of learners.
-Through classroom study, you may be granted access to helpful software and devices that would otherwise be hard to come by.
If you can’t find any classes in your area, another option is to study a set of guided practice tapes. Follow along with the recordings at your own speed and complete the included exercises and activities. As you learn, you’ll graduate to more difficult content and your proficiency will grow.
-Keep a notepad and pencil handy to copy dits and dahs as you hear them tabbed out. Reviewing the visual component alongside the recordings that will make it easier to recognize Morse Code messages in different forms.
One advantage of audio lessons is that they can be replayed over and over again to cement critical concepts and help you learn at a comfortable pace.
Begin to learn Morse Code by starting out with the easiest and simplest letters in the alphabet.
Some of the easiest letters are:
E (. or dit)
T (- or dah)
M (– 0r dah dah)
I (.. or dit dit)
These Morse Code letters are the only letters in Morse Code that use one or two dits and dahs and do not combine the dits and dahs.
From there, the next easiest step is to move onto the simple dit and dah combinations, those using only 2 or 3 dits and dahs.
Here are the next Morse Code letters to learn:
A (.- or dit dah)
D (-.. or dah dit dit)
G (–. or dah dah dit)
(H) (…. or dit dit dit dit)
K (-.- or dah dit dah)
N (-. or dah dit)
O (dah dah dah)
R (.-. or dit dah dit)
S (… or dit dit dit dit)
U (..- or dit dit dah)
W (.– or dit dah dah)
Finally, ending with the more difficult letters like “C”, “L”, “Q”, and “X”, that combine 4 dits and dahs in no particular “order”.
Here are the more difficult Morse Code letters:
B (-… or dah dit dit dit)
C (-.-. or dah dit dah dit)
J (.— or dit dah dah dah)
L (.-.. or dit dah dit dit)
F (..-. or dit dit dah dit)
Q (–.- or dah dah dit dah)
P (.–. dit dah dah dit)
V (…- or dit dit dit dah)
X (-..- or dah dit dit dah)
Y (-.– or dah dit dah dah)
Z (–.. or dah dah dit dit)
The reason that we recommend you learn Morse Code without visualizing is simple – if you learn Morse Code visually, your brain will have the following steps in order to translate the Morse Code you’re listening to:
-Your ears hear the code
-Your mind says, “Hey, that’s Morse Code!”
-Your brain tries to bring up an IMAGE of the Morse Code letter or number you’ve heard
-Your brain tries to match the IMAGE to the SOUND
Finally, you decide on a sound, or you miss the letter, and try to go on to the next letter
That’s how a typical brain works when trying to learn Morse Code visually – trust me, I know. I learned Morse Code via memorization from an Encyclopedia, and it will forever affect the way I hear and interpret Morse Code.
However, for people who are visual learners, learning visually may be the only way you learn.
If that’s the case, print out or( hand write) a copy of the Morse Code alphabet with each letter written out alongside its roman alphabet counterpart. Then, grab a notebook and copy each letter multiple times each day.
Even though many people think of Morse Code as a primarily audible language as it is most commonly used over the radio, don’t forget that it is also a visual language with its own written alphabet. Being able to visualize the letters as someone tries to learn Morse Code may be able to help speed up the learning process.
Here’s a great image to help if you are a visual learner:
Thanks to modern technology, you can find recordings of Morse Code just about anywhere – and you can find versions that are played back slower than what would be considered “normal” conversation.
Take advantage of these options to listen to More Code and use these recordings and videos as tools to test your learning progress.
This is especially important for learning the timing and spacing between letters and between words, as well as being able to instantly and effortlessly tell the difference between a dit and dah length of time.
Like most languages, Morse Code is both a written and auditory language. To prepare for listening to and translating dits and dahs, many people find it helpful to use their own voices to sound out letters and sentences as they practice.
Another way of incorporating the learners voice is to translate a short story, children’s book, or paragraph while recording. This is a great way of creating a simple test that can be “graded” without any outside assistance later.
As with learning anything, the more personal, entertaining, and a part of everyday life the new skill becomes, the quicker it is learned and the better it “sticks”. This can easily be applied to Morse Code. Emails, texting, grocery lists, notes to loved ones, and journaling are all great options for incorporating Morse Code into everyday life for a little bit of fun practicing as well as getting others around you interested in a new hobby as well!
The Q-code is a standardized collection of three-letter codes all of which start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio. To distinguish the use of a Q-code transmitted as a question from the same Q-code transmitted as a statement, operators either prefixed it with the military network question marker "INT" (dit dit dah dit dah) or suffixed it with the standard Morse question mark UD (dit dit dah dah dit dit).
