Train With Morse Master

May 4, 2025 by Lewin Day 14 Comments

Morse code can be daunting to learn when you’re new to the game, particularly if you need it to pass your desired radio license. However, these days, there are a great many tools to aid in the learning process. A good example is the Morse Master from [Arnov Sharma].

The Morse Master is a translator for Morse code, which works in two ways. You can access it via a web app, and type in regular letters which it then flashes out as code on its in-built LEDs. Alternatively, you can enter Morse manually using the physical key, and the results will be displayed on the web app. The Morse key itself is built into the enclosure using 3D printed components paired with a Cherry-style keyboard switch. It’s perhaps not the ideal solution for fast keying, with its limited rebound, but it’s a quick and easy way to make a functional key for practice purposes. If you want to go faster, though, you might want to upgrade to something more capable. We’d also love to see a buzzer added, since Morse is very much intended as an auditory method of communication.

We’ve seen some other great Morse code trainers before, too. If you’ve trained yourself in this method of communication, don’t hesitate to share your own learning tips below.

Do You Know Vail Code?

December 27, 2024 by Al Williams 27 Comments

We talk about Morse code, named after its inventor, Samuel Morse. However, maybe we should call it Vail code after Alfred Vail, who may be its real inventor. Haven’t heard of him? You aren’t alone. Yet he was behind the first telegraph key and improved other parts of the fledgling telegraph system.

The story starts in 1837 when Vail visited his old school, New York University, and attended one of Morse’s early telegraph experiments. His family owned Speedwell Ironworks, and he was an experienced machinist. Sensing an opportunity, he arranged with Morse to take a 25% interest in the technology, and in return, Vail would produce the necessary devices at the Ironworks. Vail split his interest with his brother George.

By 1838, a two-mile cable carried a signal from the Speedwell Ironworks. Morse and Vail demonstrated the system to President Van Buren and members of Congress. In 1844, Congress awarded Morse $30,000 to build a line from Washington to Baltimore. That was the same year Morse sent the famous message “What Hath God Wrought?” Who received and responded to that message? Alfred Vail.

The Original Telegraph

Telegraphs were first proposed in the late 1700s, using 26 wires, one for each letter of the alphabet. Later improvements by Wheatstone and Cooke reduced the number of wires to five, but that still wasn’t very practical.

Samuel Morse, an artist by trade, was convinced he could reduce the number of wires to one. By 1832, he had a crude prototype using a homemade battery and a relatively weak Sturgeon electromagnet.

The World Morse Code Championship

December 17, 2024 by Al Williams 54 Comments

If you were in Tunisia in October, you might have caught some of the Morse Code championships this year. If you didn’t make it, you could catch the BBC’s documentary about the event, and you might be surprised at some of the details. For example, you probably think sending and receiving Morse code is only for the elderly. Yet the defending champion is 13 years old.

Teams from around the world participated. There was stiff competition from Russia, Japan, Kuwait, and Romania. However, for some reason, Belarus wins “almost every time.” Many Eastern European countries have children’s clubs that teach code. Russia and Belarus have government-sponsored teams.

2024 Tiny Games Contest: Morse Quest Goes Where You Do

September 2, 2024 by Kristina Panos 11 Comments

Do you know Morse code already? Or are you maybe trying to learn so you can be an old school ham? Either way, you could have a lot of fun with [felix]’s great little entry into the 2024 Tiny Games Contest — Morse Quest.

This minimalist text-based adventure game is played entirely in Morse code. That is, the story line, all the clues, and the challenges along the way are presented by a blinking LED. In turn, commands like LOOK, TAKE, and INVENTORY are entered with the slim key on the lower right side. A wee potentiometer allows the player to adjust the blink rate of the LED, so it’s fun for all experience levels. Of course, one could always keep a Morse chart handy.

The brains of this operation is an Arduino Nano, and there’s really not much more to the BOM than that. It runs on a 9 V, so theoretically it could be taken anywhere you want to escape reality for a while. Be sure to check out the demo video after the break.

Ham Radio Paddles Cost Virtually Nothing

May 4, 2024 by Al Williams 22 Comments

If you don’t know Morse code, you probably think of a radio operator using a “key” to send Morse code. These were — and still are — used. They are little more than a switch built to be comfortable in your hand and spring loaded so the switch makes when you push down and breaks when you let up. Many modern operators prefer using paddles along with an electronic keyer, but paddles can be expensive. [N1JI] didn’t pay much for his, though. He took paperclips, a block of wood, and some other scrap bits and made his own paddles. You can see the results in the video below.

When you use a key, you are responsible for making the correct length of dits and dahs. Fast operators eventually moved to a “bug,” which is a type of paddle that lets you push one way or another to make a dash (still with your own sense of timing). However, if you push the other way, a mechanical oscillator sends a series of uniform dots for as long as you hold the paddle down.

Modern paddles tend to work with electronic “iambic” keyers. Like a bug, you push one way to make dots and the other way to make dashes. However, the dashes are also perfectly timed, and you can squeeze the paddle to make alternating dots and dashes. It takes a little practice, but it results in a more uniform code, and most people can send it faster with a “sideswiper” than with a straight key.

Keebin’ With Kristina: The One With The Transmitting Typewriter

April 25, 2024 by Kristina Panos 5 Comments

Okay, so we’re opening with more than just a keyboard, and that’s fine. In fact, it’s more than fine, it’s probably the cutest lil’ ZX Spectrum you’ll see today.

[SrBlonde]’s wonderful micro Spectrum project has only the essential inputs, which makes for an interesting-looking keyboard for sure. Inside you’ll find an Orange Pi Zero 2 board loaded with Batocera so [SrBlonde] can play all their favorite childhood games on the 5″ IPS display.

Something else that’s interesting is that the switches are a mix of blues and blacks — clickies and linears. I can’t figure out how they’re distributed based on the numbers in the components list, but I could see using clickies on the alphas and linears everywhere else (or vice versa). At any rate, it’s a great project, and you can grab the STL files from Thingiverse if you’re so inclined.

Inside America’s Last Morse Code Station

March 8, 2024 by Al Williams 42 Comments

The Titanic famously (or infamously) used Morse code to call out in distress at the end of its final voyage. Ships at sea and the land-based stations that supported them used Morse code for decades, but with the growing use of satellites, maritime Morse code ended in 1999. With one notable exception. [Saahil Desai] writing in the Atlantic tells the story of America’s last Morse code station, KPH just north of San Francisco.

In fact, KPH did shut down in 1997 as part of the wind down of Morse code in ocean vessels. But some radio enthusiasts, including [Tom Horsfall] and [Richard Dillman], have brought the venerable station back to life. The radio squirrels, as they call themselves, dutifully send news and weather every Saturday to anyone interested in listening. They also exchange radio traffic, primarily with the SS Jeremiah O’Brien, a World War II-era ship parked nearby. N2FQ visited the station and operated the station on video, which you can see below. Or, check out the tour in the second video, below.
