Ham Radio: More Popular Than the Obligation Ever Made It
Amateur operators call Morse code "CW," short for continuous wave, describing the type of signal it produces. CW predates voice transmission by roughly two decades and remains the most spectrum-efficient mode a human operator can run without a computer generating the signal.
Critics expected interest to collapse once licensing bodies dropped the Morse requirement. It did not. The FCC removed the requirement for every US amateur license class in February 2007, and CW participation has grown since, largely because people now choose it out of genuine interest rather than obligation. The CQ World Wide CW Contest each November regularly draws tens of thousands of entrants from more than 100 countries, which is not a niche turnout by any measure.
Serious CW operators copy code at 30 to 40 words per minute, faster than most people type on a keyboard. At that speed the patterns become automatic, the way a fluent reader recognizes whole words by shape rather than sounding out letters. A skilled ear pulls signals out of noise that would sound like static to a voice operator.
The practical draw is DXing, contacting distant stations. A CW signal occupies roughly 150 to 500 Hz of spectrum, against 2,400 to 3,000 Hz for a comparable voice transmission. Concentrating the same transmitter power into a narrower slice improves the signal-to-noise ratio at the receiving end, which is why QRP operators running just 5 watts (about what an LED bulb draws) regularly complete transatlantic and transpacific contacts on CW.
Aviation: A Backup Signal Riding Under GPS
Every time a pilot tunes a VHF omnidirectional range beacon, known as a VOR, the receiver also picks up a continuously broadcast Morse identifier, a two- or three-letter code like ... ..-. --- for San Francisco. That tells the pilot the correct station is tuned rather than a neighboring one on an adjacent frequency.
Pilots do not need to decode it by ear. Modern avionics display it as text automatically, including aircraft with fully digital glass cockpits that lean primarily on GPS. The Morse signal is still transmitted underneath, still required by aviation standards.
The reason thousands of VORs remain active in 2026 comes down to redundancy. GPS can fail, get jammed, or be spoofed, and VOR provides an independent ground-based reference that satellites cannot interfere with. The FAA's Minimum Operational Network plan identifies which VORs stay online as that backup layer, and while some stations have been decommissioned, the network and its Morse identifiers remain firmly in place.
One Switch, a Full Keyboard
This is probably the least expected corner of Morse code's survival. People who cannot use a standard keyboard or touchscreen, due to ALS, cerebral palsy, spinal cord injury, or other conditions affecting fine motor control, can get full text input through a single physical switch using Morse.
The principle is simple: a short press is a dot, a longer press is a dash, and software decodes the timing into letters. That switch might be a button held in one hand, a device mounted near the head, a sip-and-puff sensor, or something that reads eye-blink duration.
Apple built Morse input into iOS and iPadOS via Switch Control in 2018. Google added Morse input to Gboard on Android the same year. Both ship at no extra cost as part of the operating system, a real shift from the specialized and often expensive assistive tools that came before. Someone with limited motor control can pick up an ordinary phone, turn on the feature, and reach the entire keyboard, emoji included. For the deeper backstory on how the code got this far, see the history of Morse code.
Military Use: Documented Mostly by What Is Missing
Current military use of Morse code is not well covered in open sources, and that gap is itself informative. HF radio on shortwave bands can reach thousands of miles with minimal infrastructure, and a Morse transmission there occupies a very narrow slice of spectrum, harder to locate by direction-finding than a voice signal. It also holds up at signal levels too weak for intelligible speech.
Several special operations units and military training programs worldwide have kept Morse in their curricula. The specifics stay private. What is public is that the skill persists for roles that might need to operate with minimal gear, under emissions-control conditions, or where digital infrastructure cannot be trusted.
The Physics Argument
Strip away sentiment and three properties explain why nothing else has fully displaced Morse in its niches. Bandwidth: a CW signal is narrow enough that a single frequency slot able to hold one voice call can instead hold dozens of simultaneous CW contacts. Noise tolerance: human ears and modest software decoders can pull Morse out of signal levels that render speech useless, though newer weak-signal digital modes like FT8 push this further still. Equipment simplicity: a working transmitter needs little more than an oscillator, an amplifier, a key, and a length of wire, with no codec and no firmware, which matters in emergency scenarios where commercial infrastructure has failed.
Cultural Residue
Morse's most recognized export, ... --- ..., appears in films, games, escape rooms, and novels as shorthand for trouble, understood by people who know nothing else about the code. Escape room designers in particular like Morse because it reads as a cipher while staying solvable with a reference card taped to the wall, a narrow zone few other codes occupy. The patterns that show up most often in practice are catalogued on the common Morse code words page.
Where This Leaves Things
Morse code is not a museum piece. It runs daily through hundreds of thousands of amateur radio contacts, rides quietly under aviation beacons overhead, and gives people who need it a way into a full keyboard. It has outlived predictions of its death for well over a century, and the technical reasons behind that have not changed. A mode this efficient with spectrum, this tolerant of noise, and this simple to build rarely goes quietly, and there is no sign it plans to now.
