There’s a certain magic to Morse code, or CW (Continuous Wave) as it’s known in the amateur radio world. It’s a language of rhythm and tone, a direct connection to the roots of radio communication. For years, I was captivated by the idea of mastering it. The thought of tapping out messages that could circle the globe with simple equipment was intoxicating. But the reality of learning was, for a long time, a significant barrier. The traditional path often involved buying a full transceiver, setting up an antenna, and finding an oscillator—a costly and space-consuming endeavor just to practice the basic dits and dahs. I, like many aspiring operators, needed a bridge. I needed a dedicated, portable, and modern tool that could provide instant feedback without the complexity and cost of a full station. The frustration of wanting to learn but being blocked by a high barrier to entry is a common story, and it’s precisely this problem the Putikeeg Mini CW Trainer Morse Code Telegraph Key aims to solve.

What to Consider Before Buying a CW Training Device
A CW Trainer is more than just a noisemaker; it’s a key solution for aspiring HAM radio operators, survival communication enthusiasts, and anyone fascinated by this classic skill. It isolates the learning process from the complexities of radio transmission, allowing you to focus purely on sending and receiving code. The primary benefits are immense: portability for practice anywhere, focused training modes that drill letters and words, and instant feedback that you simply can’t get from a simple oscillator. It turns a daunting skill into a manageable, even game-like, experience. It’s an investment in a foundational skill that opens up a world of communication possibilities, from contesting and DXing (long-distance contacts) to essential off-grid messaging.
The ideal customer for this type of product is someone at the beginning of their CW journey. They are motivated to learn but may not have the budget or space for a full radio setup. This includes new amateur radio licensees, preppers building their communications toolkit, or even hobbyists who see Morse code as a fascinating mental exercise. It’s also perfect for experienced operators who want a compact device for warming up or practicing on the go during activities like POTA (Parks on the Air) or SOTA (Summits on the Air). Conversely, this might not be suitable for those who need advanced features like QSO simulation with adaptive speed or integration with logging software. For them, PC-based software might be a better fit. Likewise, if your primary goal is simply to listen to radio broadcasts, a dedicated shortwave receiver would be a more appropriate choice.
Before investing, consider these crucial points in detail:
- Dimensions & Portability: The very purpose of a device like this is to practice anywhere. We looked for a unit that was small and light enough to toss in a bag without a second thought. Battery life is also a key part of portability; a device that needs constant charging is tethered, defeating the purpose. USB-C charging is a modern standard we now expect for convenience.
- Features & Performance: A good trainer needs more than just a sidetone. We evaluated the variety and usefulness of its training modes. Does it offer free-form practice with real-time decoding? Does it have modes to quiz you on sending and receiving individual characters or common abbreviations? Support for both iambic paddles and a straight key is also essential to accommodate different learning styles.
- Materials & Durability: While these devices are not typically built for extreme environments, the construction must be solid enough for travel. We paid close attention to the quality of the casing, the feel of the buttons, and, most importantly, the durability of the key input jack. A flimsy 3.5mm socket is a common point of failure and can render the entire unit useless.
- Ease of Use & Interface: Learning Morse code is hard enough; the tool you use shouldn’t add to the frustration. We assessed the intuitiveness of the menu system and the clarity of the display. A screen that is difficult to read due to low contrast or aggressive backlighting can be a significant drawback, especially during long practice sessions.

First Impressions: Unboxing the Putikeeg Mini CW Trainer Morse Code Telegraph Key
The Putikeeg Mini CW Trainer Morse Code Telegraph Key arrived in a compact, no-frills box that immediately signaled its purpose: utility over luxury. Inside, the device itself, a vibrant green, felt surprisingly lightweight at just over 7 ounces. It’s small enough to fit comfortably in the palm of your hand, making its promise of portability immediately believable. The package includes the trainer and a USB-A to USB-C charging cable, which is a welcome modern touch. The casing is a simple plastic, which keeps the weight down but doesn’t inspire confidence for rough handling. The front is dominated by the 1.3-inch digital display and a set of small, tactile buttons for navigation. On the side, you find the 3.5mm jacks for your key and for headphones—a crucial feature for quiet practice. Firing it up for the first time, the screen came to life, revealing a simple, text-based menu.

A Comprehensive Field Test: Performance and Usability
A CW trainer lives or dies by how well it facilitates practice. A feature list is one thing, but the real test is hours of hands-on keying. We put the Putikeeg Mini CW Trainer Morse Code Telegraph Key through its paces, connecting both a classic straight key and a set of iambic paddles to evaluate its full range of capabilities. Our experience was a fascinating, and at times frustrating, mix of brilliant design and questionable execution.
The Core of the Trainer: Practice Modes and Decoding Accuracy
This is where the Putikeeg truly shines. The software packed into this little box is remarkably capable. We spent the majority of our time in the three main modes, and each serves a distinct, valuable purpose. The “Free Mode” is arguably the most useful feature; as you send code, the device decodes it in real-time and displays the characters on the screen. For a beginner struggling with timing and spacing, this instant visual feedback is invaluable. We found the decoder to be surprisingly accurate, correctly interpreting our sending across a range of speeds from a slow 5 WPM up to a more respectable 20 WPM. This confirms what many users have found, with one noting it was “pretty much exactly what I was looking for to learn Morse code.”
The quiz modes add a structured layer to practice. The “Listening Test” plays a series of random letters, numbers, or common Q-codes (abbreviations), forcing you to copy them by ear—a critical skill for on-air operation. The “Code View” mode allows you to query specific characters, helping you drill the ones you struggle with. This suite of features transforms the device from a simple oscillator into a genuine teaching tool. The ability to plug in headphones is another massive advantage, allowing for late-night practice sessions without disturbing anyone. The sidetone (the audible beep) is clear and its volume is adjustable, which is a simple but essential feature. For its core purpose—providing a versatile and responsive practice environment—the software design is a home run. You can see its full feature set and user reviews to get a better sense of its capabilities.
Interface and Ergonomics: A Tale of Two Experiences
While the software is smart, interacting with it can be a challenge. This brings us to the device’s most significant ergonomic flaw: the navigation buttons. During our testing, we encountered the exact issues described in user feedback. The buttons are tiny and require a firm, precise press. We frequently experienced unregistered pushes, forcing us to press again, and just as often, a single press would be interpreted as two or three, causing us to fly past the desired menu option. This is incredibly frustrating when you’re simply trying to adjust the WPM speed or switch practice modes. For a device centered on rhythm and timing, having such an unreliable physical interface is a major oversight.
The 1.3-inch digital display is another area of compromise. In good, indirect light, it’s perfectly adequate for displaying the decoded characters and menu options. However, as one user accurately pointed out, its performance suffers in other conditions. In low light, the backlight tends to wash out the text, making it appear faint and reducing legibility. In bright, direct light, the screen is prone to glare. While the contrast is adjustable in the settings, we were never able to find a level that made it universally crisp and clear. It’s a functional display, but it feels like a component chosen for cost savings rather than optimal user experience, which is a shame given the intelligence of the software it’s displaying.
Build Quality and Long-Term Reliability
This is the elephant in the room. For every user praising the trainer’s functionality, there seems to be another with a story of hardware failure. Our review unit performed flawlessly from a functional standpoint during our testing period. It powered on, took a charge via its USB-C port, and both 3.5mm jacks were solid. However, we cannot ignore the significant volume of reports highlighting serious quality control issues. We read accounts of units arriving dead on arrival, refusing to charge. More concerning is the report from a user whose key socket failed after just 20 days due to a bad solder joint inside the device. This is a catastrophic failure that renders the trainer useless.
The lightweight plastic construction, while great for portability, does little to assuage these fears. It doesn’t feel fragile, but it certainly doesn’t feel rugged. This presents a difficult value proposition. The Putikeeg Mini CW Trainer Morse Code Telegraph Key is a feature-rich tool that, when it works, is a fantastic aid for learning CW. But the inconsistency in manufacturing means that purchasing one feels like a bit of a gamble. For an experienced ham with soldering skills, fixing a bad jack might be a minor inconvenience. For a beginner, it could be a complete waste of money and a source of immense frustration that might even discourage them from continuing to learn the skill.
What Other Users Are Saying
A survey of user feedback reveals a starkly divided opinion on the Putikeeg Mini CW Trainer Morse Code Telegraph Key. The sentiment is highly polarized, with users either loving its functionality or despising its poor quality.
On the positive side, many echo our findings about its effectiveness as a learning tool. One satisfied user states, “This little box works wonders if you’re trying to learn CW,” highlighting its versatility with both paddles and straight keys, its freestyle decoding mode, and its portability. Another beginner, who isn’t even a licensed HAM operator yet, found it to be the perfect entry point, saying it was “exactly what I was looking for to learn Morse code as a skill.” These reviews underscore that the core concept and software are spot-on for the target audience.
However, the negative feedback is serious and consistent. The most severe critiques focus on build quality. We saw multiple reports of units that were dead on arrival or failed within weeks. “Unit arrived and will not power up. Does not take a charge,” is a deeply disappointing experience for any customer. Another user had the key socket’s internal solder fail after only six uses. This points to a significant lapse in manufacturing quality control. Combined with complaints about the “very difficult to use” buttons and hard-to-read display, it paints a picture of a product with great potential that is critically hampered by its physical execution.
How Does It Compare? Putikeeg CW Trainer vs. The Competition
While the Putikeeg Mini CW Trainer Morse Code Telegraph Key occupies a very specific niche, potential buyers in the broader radio hobby might be weighing it against general-purpose receivers. It’s crucial to understand that these products serve fundamentally different purposes. The Putikeeg is an active training device for a specific skill, whereas the alternatives are passive listening devices for entertainment and information.
1. Crosley CR31D-WA Retro Bluetooth Speaker

The Crosley CR31D-WA is all about style and casual listening. It’s designed to be a beautiful piece in a living room, combining a vintage AM/FM radio aesthetic with modern Bluetooth speaker functionality. Someone would choose the Crosley for its looks and its ability to stream music from a phone. It offers zero functionality for learning or practicing Morse code. The choice is clear: if you want to learn a skill and participate in radio communication, the Putikeeg is the tool. If you want a stylish speaker that can also tune in a local broadcast, the Crosley is the answer.
2. Sangean WR-22WL Table-Top Digital Receiver
- 10 station presets (5 AM, 5 FM) with built-in Bluetooth wireless Audio streaming and USB MP3/ WMA playback
- Easy to read high contrast LCD display with automatic and adjustable backlight

The Sangean WR-22WL represents a step up in audio quality and reception for broadcast listening. It’s a high-fidelity tabletop receiver with AM/FM, Bluetooth, and USB playback, encased in an elegant walnut cabinet. Its primary strength is providing rich, clear audio for music and talk radio. Comparing it to the Putikeeg is like comparing a concert piano to a typing tutor. The Sangean is for consumption and enjoyment of broadcast content. The Putikeeg Mini CW Trainer Morse Code Telegraph Key is for the creation and practice of CW communication. An operator might own both—the Sangean for their workshop and the Putikeeg for their desk.
3. Sangean U3 Ultra Rugged Jobsite Radio
Here, the comparison point is durability. The Sangean U3 is built like a tank. It’s designed to be knocked around on a construction site, with a protective roll cage and water resistance. This is the radio you buy when you need something that can withstand abuse. The Putikeeg, with its lightweight plastic shell and reports of delicate solder joints, is the polar opposite. It’s a device that needs to be handled with care. If your priority is extreme ruggedness for listening in harsh environments, the Sangean U3 is the only choice. If your priority is a portable, feature-rich CW trainer for use in a protected setting (like a desk or a park on a sunny day), the Putikeeg is the specialized tool for that job.
Final Verdict: Is the Putikeeg Mini CW Trainer Morse Code Telegraph Key the Right Choice for You?
After extensive testing and careful consideration of user feedback, our verdict on the Putikeeg Mini CW Trainer Morse Code Telegraph Key is one of conditional recommendation. The concept is brilliant, and the software execution is fantastic. For a beginner, the combination of real-time decoding, multiple practice modes, and extreme portability offers an incredible platform for mastering Morse code. When you get a good unit, it “works wonders” and can genuinely accelerate the learning process.
However, this praise is tempered by significant and undeniable concerns about quality control and usability. The frustrating buttons and mediocre display are design flaws, but the reports of DOA units and early hardware failures are unacceptable. This turns the purchase into a gamble. We recommend it to the aspiring CW operator who is willing to take that chance, perhaps prepared to handle a return or even a minor repair, for the sake of the excellent training features. It is a powerful tool trapped in a flawed body. If you receive a fully functional unit, you will likely love it.
