Ukraine war: Why the Russian army is still using morse code more than a century after its invention

Fashionable warfare is awash with cutting-edge know-how—from AI to drones to hypersonic missiles—but one know-how that’s greater than a century outdated remains to be proving its value: Morse code.

The staccato streams of tones that might be immediately recognizable to a railroad man from greater than 150 years in the past are nonetheless in use by the Russian navy within the Ukraine warfare.

Even immediately, many individuals would have the ability to establish the attribute sound of Morse code, specifically, the extensively recognized sample three short, three long, three short (…– – – …), forming the emergency sign SOS.

Immediately Morse code messages are being despatched from Russian bombers to their management facilities, or from ships of the Baltic Fleet to their shore-based headquarters.

The shortwave bands utilized by beginner radio fans are equally filled with the beeps recognized by fans as “dits” (.) and “dahs” (-), or as dots and dashes by the broader public. Even spies nonetheless tune in to the shortwave bands to take heed to clandestine stations broadcasting Morse code.

Invented within the 1800s

Why then, is a know-how created within the first half of the 1800s nonetheless in use immediately?

First, Morse code was envisioned not by an engineer or technological wizard, however by a person who painted portraits for a residing. Samuel Morse initially designed what we immediately would name a teleprinter, a tool that receives and prints textual content on paper.






The sound of morse code.

Morse enlisted the assistance of the extra mechanically inclined Alfred Vail, a machinist, to work out the main points. It was the latter who created the dots and dashes to signify the code, and got here up with the concept of utilizing sound to convey data.

Initially, the sound was merely supposed for use to test a connection. Earlier than lengthy, Morse and Vail realized that the idea of printing was impractical. By including sound, nonetheless, that they had stumbled upon an idea extra good and helpful than they might think about.

The outstanding attribute of Morse code is that in sound type, it types a rhythm. Thus, it shares widespread floor with music. Actually, it has been famous that individuals with musical expertise are capable of begin learning morse more quickly.

By stimulating the innate human sense of rhythm, Morse code additionally prompts our sense of sample recognition. It is a talent deeply embedded in our brains, and one which has nice potential to decipher messages even when they’re incomplete.

An skilled Morse code operator can fill within the blanks brought on by interference, poor reception, noise or gear malfunction. In a neurological sense, morse inhabits a really peculiar area of interest, likened to “reading with the ears” however the place transmitting and receiving it resembles the act of speaking greater than writing.

The opposite outstanding facet of Morse code is its technological simplicity. Anybody with primary technological expertise can build their own transmitter utilizing customary elements.

The sign generated by a morse transmitter is equally minimalistic, utilizing a particularly slim bandwidth of only 100–150 hertz (customary voice communications use 2,500–3,000 hertz). This additionally implies that receivers can use very slim filters and thus take away a lot of the encircling noise generated by varied types of interference.






Since it’s so efficient, morse solely wants a minimal of energy to journey important distances. Novice radio fans demonstrated in 1956 that as little as 78 milliwatts can be enough power to transmit from Massachusetts to Denmark. That is lower than a tenth of what a single LED lightbulb makes use of. An ordinary espresso maker making ready most individuals’s favourite morning brew makes use of greater than a thousand occasions extra energy.

This mix of technological simplicity and effectivity got here in helpful in the course of the second world warfare, when resistance members and Allied commandos used their portable Morse transceivers to keep up contact with London from deep inside German-occupied territory.

This was a really dangerous enterprise, because the Germans have been continually listening in on the airwaves. Morse code, whereas being unintelligible to the untrained ear, gives no safety in and of itself.

Immediately, even these with out coaching can use software to decipher the contents of a message despatched utilizing Morse code. Nevertheless, any message could be made safe by encrypting it earlier than sending it, as proposed by Vail in 1845.

Actually, one of the safe types of encryption, the one-time pad, requires nothing greater than pen and paper. In essence, a one-time pad is a random string of characters, no less than so long as the message that’s going to be encrypted.

The sender makes use of his or her pad to encrypt, whereas the recipient makes use of a duplicate of the identical pad to decode the message (there needs to be solely two copies, and every needs to be destroyed instantly after use). So long as a pad is rarely reused, it stays theoretically unbreakable even with essentially the most fashionable know-how (though, really random sequences of characters are difficult to produce).

Whereas there are extra environment friendly digital modes of communication immediately, nothing can rival the unsurpassed mixture of simplicity and effectivity that has allowed Morse code to outlive for greater than 150 years.
