CW Decoder vs Morse Dot

High-Precision Morse Code Decoder Achieve noise-resistant, accurate Morse code decoding with high-precision, sample-level signal processing. Try the superior “listening performance” in the free version. Differences Between Free and Full Versions This app lets everyone try the high-performance decoding engine for free. Free Version - Continuous decoding: Up to 3 minutes per session (restart anytime, unlimited times) - Basic font display Ideal for testing performance and checking short communications. Full Version (Paid Add-on) - Unlimited time: For long ragchews and continuous monitoring - Font settings: Customize font type and size for better visibility Recommended for active operation and a stress-free learning experience. Main Features & Technology High-Precision Real-Time Decoding - Speed range: 5–50 WPM (auto-adjust speed and threshold) - Frequency detection: 400–900 Hz (automatically tracks the strongest signal) Advanced Signal Processing - Bandpass filter: Narrowband filtering reduces unwanted noise - AGC (Automatic Gain Control): Compensates for signal level changes and fading - Noise blanker: Reduces spike noise using MAD (Median Absolute Deviation) - Signal stabilization: Multi-sample buffering helps prevent false detections Designed for Real-World Use - Scrollable text: Review and check missed content - Frequency lock: Tracks the actual operating frequency range (400–900 Hz) - Visual support: On-screen text supports listening and copying Recommended For Morse Code Beginners Great for those getting started with Morse code. Seeing decoded text while listening helps self-correction and improves learning efficiency. Amateur Radio Operators - CW practice: Compare results with your own copying to find weak points - Contests: Helpful for high-speed reception support and log checking - Portable ops: No PC needed—build a CW reception setup with just a smartphone Comeback Hams & Experts Useful for reducing fatigue during long monitoring sessions and supporting operators with hearing decline. Powerful filtering helps decoding in weak-signal or interference conditions. Note: Microphone permission is used only for signal analysis. No audio is saved or transmitted.

Learning Morse Code should feel clear, physical and personal. Morse Dot turns your phone into a pocket Morse signal gadget. Tap Dit and Dah, hear each tone, feel the feedback, and practise Morse through sound, touch and rhythm. You can slow down the speed when learning, increase it when ready, and fine-tune the spacing between signals, letters and words. Instead of only memorising symbols, Morse Dot helps you build rhythm, timing and confidence through repeated practice. What you can do with Morse Dot: • Use your phone like a pocket Morse signal device • Tap Dit and Dah with a physical-feeling signal pad • Hear clear Morse tones as you practise • Feel feedback while sending signals • Adjust WPM speed for your own level • Fine-tune spacing between dits, dahs, letters and words • Convert text into Morse Code • Decode Morse Code back into readable text • Replay Morse messages to hear the rhythm again • Create secret Morse messages and share them with friends • Let friends copy, listen, decode and discover the hidden text • Copy signals and decoded text for messaging apps • Practise short signals, words or full messages • Build confidence through repeated feedback Morse Dot is useful for learning Morse Code, practising signal rhythm, exploring radio-style communication, or simply sending hidden messages to friends. Type a message, turn it into Morse Code, listen to how it sounds, adjust the timing, then share the signal. Your friends can copy the Morse message, play it back, decode it and discover what you sent. Every Morse sender has their own rhythm. Morse Dot lets you tailor the speed, spacing and feel so your practice becomes more natural, physical and personal. Carry a Morse gadget in your pocket. Feel the signal. Adjust the rhythm. Send Morse your way.
