Got my N3ZN Single-Lever Paddle out of storage, along with most of my POTA station. Despite being homeless and living in the hotel for the last few months (see my personal story on my website), I am trying to keep my brain active and that includes Morse code practice. Why? Besides the health benefit, I want to start getting out into the hotel parking lot and set up to work POTA stations.

Eventually, I will get to an official POTA-registered park, too. We became homeless just as I was planning on activating Ohio parks. Now, I am in Nebraska, and as a disabled veteran, can get into some parks without any big fees.

What is left before I can activate a POTA location? I need to find the antenna and coax assembly that I put together for the whole station. In the meantime, I am practicing to get the cobwebs out of my brain and re-learn that muscle memory. Will also do a lot of receiving practice. Gotta get my brain in gear! Read more about POTA, here.

The Spark in the Wire: How Re-Learning Morse Code Rewires the Brain

There is a unique rhythm to Continuous Wave (CW) amateur radio. As I sit at the key, shaking off the cobwebs and practicing to regain that deep muscle memory, I can feel my brain kicking into a higher gear. It isn’t just about nostalgia or the thrill of making a contact through the static using nothing but tones. There is real, hard science behind why copying and sending Morse code feels like a cognitive tune-up.

In preparing to share this journey, I dove into the research surrounding how learning and practicing CW impacts our neurology. What I discovered confirms what many of us experienced operators have long suspected: Morse code is a powerhouse for brain health and cognitive longevity.

The Cognitive Science of CW

When we sit down for a session of receiving practice, we aren’t just listening to dots and dashes. We are engaging in a complex, multi-sensory cognitive exercise. Research shows that mastering Morse code alters the brain’s structure and functional connectivity in profound ways.

* Neuroplasticity in Action: Studies in neuroimaging have revealed that learning Morse code increases the microstructural integrity of the white matter tracts connecting the auditory and motor cortices. By translating sound directly into physical movement (sending) and physical movement or mental text into meaning (receiving), we are literally forging new neural pathways.

* Bi-Hemispheric Engagement: Unlike ordinary speech, which is heavily localized in the left hemisphere of the brain, processing Morse code recruits areas across both the left and right hemispheres. The left side handles the structural, analytical translation of the code, while the right side processes the rhythmic, musical elements of the pitch and timing.

* Enhancing Working Memory: Receiving CW at higher speeds requires a robust “audio buffer” in your working memory. You must hold the sounds of the characters in your mind, decode them, and write them down or copy them in your head, all while the next characters are already pouring into your ears. This builds tremendous cognitive reserve.

The Koch Method: Training the Brain the Right Way

When I first learned Morse code, and now as I work to bring that muscle memory back, the method of training matters immensely. Trying to count dots and dashes visually or memorizing a chart is a trap. It creates a cognitive bottleneck that falls apart at higher speeds.

That is where the Koch method comes in, a technique that aligns perfectly with how our brains naturally process fast, rhythmic information.

* Full Speed from Day One: Invented by German psychologist Ludwig Koch, this method dictates that you listen to characters at your target speed right from the start, typically 20 words per minute or faster.

* Preventing the “Counting” Habit: By keeping the character speed high, your brain is physically incapable of counting the individual dots and dashes. Instead, you are forced to learn the overall rhythmic “sound basket” or shape of the letter.

* Incremental Success: You start with just two characters. Once you can copy them with 90% accuracy, you add a third, then a fourth. This builds immediate, reflexive muscle memory rather than analytical translation.

CWops, CW Academy, and LICW: Modern Gold Standarda

In my exploration of modern training tools that honor this science, I found that the amateur radio community has perfected this instructional approach. Organizations like CWops, through their renowned CW Academy, have taken the core principles of the Koch method and elevated them for the modern era. Another adaptation from the Koch method is the Long Island CW group (LICW) website and support structure.

* Rhythm and Spacing: CW Academy utilizes effective spacing methods related to the Koch philosophy. They send characters at a high effective speed so your brain learns the correct sound patterns immediately, while widening the space between the characters to give your mind time to process them.

* Structured Discipline: Their programs offer the exact kind of structured environment required to overcome writer’s block or training plateaus. It combines the rigorous discipline of daily practice with the support of a community.

* Interactive Learning: By pairing rigorous receiving practice with peer interaction, they stimulate the social and cognitive centers of the brain simultaneously, maximizing the neuroplastic benefits of the hobby.

Final Thoughts: Getting the Gears Turning

Re-learning CW is more than just a return to a beloved pastime. It is a deliberate act of cognitive preservation. Every evening spent copy-practicing and burning those pathways back into my hands is an investment in focus, memory, and mental sharpness. The science proves it, but sitting at the desk, feeling the cobwebs clear as the code starts to flow naturally once again, is all the proof I truly need.

Here’s just some practice after adjusting the key gap spacing and tension.

Curious about what you can hear on shortwave ham radio? This video is a brief survey of the diverse world of communications on the shortwave spectrum. Expand your radio horizons and enhance your emergency communication preparedness by tuning in to the world of shortwave ham radio.

If you’ve started delving into radio communications beyond local stations and channels, like VHF and UHF, you’re in for a treat. Shortwave radio opens up a whole new realm of signals to explore, including emergency communications vital during natural disasters.

Shortwave radio covers a range of radio frequencies from 3 kHz to 30 MHz. This spectrum is home to a diverse array of radio signals that cater to various communication needs, making it a hub of activity and connectivity.

Within these high frequencies, you can tune in to a multitude of transmissions, from transoceanic air traffic control communications to the chatter of ships navigating the vast seas. Imagine hearing the voices of fishermen, much like those on your favorite reality TV shows about high-seas fishing adventures, along with military communications and the vibrant world of amateur radio enthusiasts.

One of the remarkable features of high-frequency (HF) radio is its ability to propagate signals over long distances, transcending line-of-sight limitations. This means that HF radio enables communication between different regions and even continents, fostering connectivity across vast distances.

During times of crisis and natural disasters, shortwave frequencies become invaluable for emergency communications. When local infrastructure falters or is disrupted, shortwave radio serves as a vital lifeline, facilitating critical two-way communications in and out of disaster-stricken areas.

Explore the fascinating realm of shortwave radio, where distant voices blend with essential information, bridging gaps and connecting communities in times of need. Uncover the power of HF radio to transcend boundaries and provide lifelines when they are needed most.

In this video, I give you a glimpse of the voice and data transmissions I pick up on my high-frequency amateur radio transceiver (in this video, an Icom IC-7000). In later videos, I will dive deeper into specific types of HF communications, such as aeronautical trans-oceanic signals.

Turning back time to virtually witness a critical historic method of shortwave communication using the fundamental mode of continuous wave modulation. This is a film from 1944, teaching the basics of Morse code, for military comms.

What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code key? Ham radio operators find Morse code (and the ‘CW’ mode, or ‘Continuous Wave’ keying mode) very useful, even though Morse code is no longer required as part of the licensing process. Morse code is highly effective in weak-signal radio work. And, preppers love Morse code because it is the most efficient way to communicate when there is a major disaster that could wipe out the communications infrastructure.

While this military film is antique, the vintage information is timeless, as the material is applicable to Morse code, even today.

This video is an introduction to an international public-service and technology hobby known as ‘amateur radio’ (or ‘ham radio’).

Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term “amateur” is used to specify “a duly-authorized person interested in radioelectric practice with a purely personal aim and without pecuniary interest;” (either direct monetary or other similar rewards) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government’s radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. According to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio. About 830,000 amateur radio stations are located in IARU Region 2 (the Americas) followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about 750,000 stations. A significantly smaller number, about 400,000, are located in IARU Region 1 (Europe, Middle East, CIS, Africa).

Activities and practices

The expansive diversity found in the amateur radio hobby attracts practitioners who have a wide range of interests. Many hams begin with a fascination of radio communication and then combine other personal interests to make the pursuit of the hobby rewarding. Some of the focal areas amateurs pursue include radio contesting, radio propagation study, public service communication, technical experimentation, and computer networking. But, that is just a sampling of interest areas found in the hobby.

Amateur radio operators use various modes of transmission to communicate. The two most common modes for voice transmissions are frequency modulation (FM) and single sideband (SSB). The FM mode offers high-quality audio signals, while SSB is better at long distance communication when bandwidth is restricted.

Modern personal computers have encouraged the use of digital modes such as radioteletype (RTTY) which previously required cumbersome mechanical equipment. Hams led the development of packet radio in the 1970s, which has employed protocols such as AX.25 and TCP/IP. Specialized digital modes such as PSK31 allow real-time, low-power communications on the shortwave bands. More robust digital modes have been invented and improved, including such modes as Olivia, JT65, and WSPR.

NASA astronaut Col. Doug Wheelock, KF5BOC, Expedition 24 flight engineer, operates the NA1SS ham radio station in the Zvezda Service Module of the International Space Station. Equipment is a Kenwood TM-D700E transceiver.

Amateur radio operators, using battery- or generator-powered equipment, often provide essential communications services when regular channels are unavailable due to natural disasters or other disruptive events.
