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.
