Answers to Questions (FAQ)
What is Morse Code? (Definition)
Morse code is an alphabet for encoding a message by short and long pulses (such as sounds, visual/light signals, electrical, etc.). Adopted internationally, the Morse alphabet is a precursor in telecommunications, although obsolete with the advent of digital, there are traces of it in military, maritime or radio transmissions or for the SOS code.
How to encrypt using Morse Code cipher?
Morse code assigns to each letter, digit, or punctuation sign, a unique combination of signals made of short and long impulsions (usually represented with a dot . and a dash -).
The alphabet or complete table of Morse Code is
Example: DCODE is coded in Morse language -.. -.-. --- -.. .
Impulsions can be electric, acoustic or luminous. Any telecommunication format is possible.
Messages sometimes starts with △ -.-.- (start of transmission) and end with ▽ .-.-. (end of transmission)
The code .-.-. is also the code for the character +.
By convention, when writing, each character is separated by a space and each word is separated by a slash /. Sometimes the characters are separated by a / and the words by a double slash //.
How to decrypt Morse Code cipher?
Morse signal decryption/translation in English uses the same alphabet as encryption, but in order to accelerate the translation process, decoders use a tree like this:
How to recognize Morse Code ciphertext?
The ciphered message is mainly composed of dots and dashes (or sometimes, any other couple of characters).
Morse code is an auditive code, any long and short beep sounds, it can be Morse
Example: bip biiiip bip = .-.
There is also a luminous variant, the presence of a clignotant light for 2 distinct durations is a Morse code handle.
Same with syllables in I or E for short and A or O for long.
Example: TATITA = -.- (long, short, long)
How to write Morse Code?
There is not really a good way or official method of writing Morse. It is first a sound code. Visually the written Morse code should be arranged on the same line. Computers, however, has trouble writing it with the dashes - or _ and the dots . which are not at the same level.
The key is to differentiate the characters: example ▄ (short) and ▄▄▄▄ (long).
How to decipher audio MP3 Morse?
Listen to the message and type simultaneously on a keyboard . (dot) for a short/acute sound and - (dash) for a long/grave one.
How to decipher Morse without spaces?
Morse deciphering without a separator can be cracked, but hardly, as possibilities are exponential. dCode has some tools, such as a brute-force attack or a dictionary attack.
Example: -.-. (4 characters) can mean 8 different things: C or KE or NN or NTE or TR or TAE or TEN or TETE
What are the variants of the Morse Cipher?
It is possible to replace the two characters for short and long by others like A and B for example. It is even possible to switch them in order to fool the decoder.
There is a fairly well known overencryption: Fractionated Morse cipher.
What is the mountain Morse code?
A variant encodes morse with a kind of mountain profile:
How has the Morse alphabet been created?
There are no real rules, however, frequent characters (E, T, A for example) are coded with short signals (1 or 2 impulsions). The less frequent letters are coded with 4 signals maximum, digits with 5.
How to learn the Morse alphabet with mnemonics?
Many methods are used, the principle is to remember 26 words, and with these words find the corresponding association between a letter and its code.
Here is a list of words where each vowel is a dot, each consonant is a dash.
Example: V is described by oooh, that has three vowels and one consonant, so V is coded in Morse with ...-
A | ax |
B | beau |
C | cola |
D | duo |
E | e |
F | uomo |
G | gnu |
H | oooa |
I | io |
J | iggs |
K | kim |
L | olei |
M | vn |
N | no |
O | pls |
P | ople |
Q | drug |
R | ice |
S | ooo |
T | t |
U | ear |
V | oooh |
W | arc |
X | heat |
Y | hanz |
Z | blue |
Another method used English pronunciation, stressed syllables standing for a dash and unstressed syllabes stands for a dot.
Example: PSYCHOLOGY, begins with a P, and contains 2 syllables in O, P is then coded in Morse .--.
A | aGAIN, aPART |
B | BE a good boy |
C | COca-Cola, CHARlie-CHARlie |
D | DRAcula |
E | eh! |
F | for the FAIRest |
G | GOOGOLplex |
H | holyday in |
I | i bid |
J | in JAWS JAWS JAWS |
K | KANGaROO |
L | liNOleum |
M | MAMA |
N | NAvy, NAzi |
O | OH MY GOD, OREO |
P | a PIZZA pie |
Q | QUEENs WEDding DAY |
R | roTAtion |
S | sisisi |
T | TALL |
U | uniFORM |
V | victory V |
W | the WORLD WAR |
X | X marks the SPOT |
Y | WHY dit I DIE |
Z | ZOO ZOO keeper |
. | a STOP, a STOP, a STOP |
, | COMMA, it s a COMMA |
? | it s a QUESTION, is it? |
To train yourself, morse code kits are available (for children and adults) to transmit Morse here (affiliate link)
How to send a SOS in Morse?
SOS is coded ...---... (3 shorts, 3 longs, 3 shorts)
How to mark the end of a character in Morse?
In practice, when a letter is finished, the morse encodes the end of a character with empty sounds (silence) or empty visuals a bit long. When retranscribing, a slash / or any separating character can be added.
Why Morse has this name?
Morse code was developed by Samuel Morse, an American scientist whose name he kept. Morse therefore has no meaning or relation to the walrus animal (morse in French).
When Morse was invented?
Morse Code was invented in 1835 by Samuel Morse
