Morse Transmitter & Decoder — The Ultimate Morse Code Suite Morse Transmitter is a simple, fast, and professional app for transmitting, translating, decoding, and learning Morse code. Whether you are an amateur radio enthusiast (ham radio), an emergency responder, a student, or just curious about digital signaling, Morse Transmitter provides a premium, state-of-the-art toolkit. Key Features 1. Advanced Video/Camera Decoder (Real-Time) Decode Morse code visually using your device's camera! Point your camera at a blinking light source (like a flashlight or beacon). Use the Target Grid Overlay to lock onto the light. Adjust the Sensitivity Slider to ensure clear detection in dark or semi-lit environments. Watch signals convert to text instantly on your screen. 2. Intelligent Audio Decoder (Microphone) Translate Morse code from sound to text in real-time. Decodes incoming audio signals using your microphone. Features an active Oscilloscope to visualize signal waves. Includes a VU volume meter and frequency adjustment settings to filter background noise. Ideal for ham radio (CW) practice and signal analysis. 3. Multi-Modal Transmitter Encode any text into Morse code and transmit it using your device's hardware: Flashlight (LED Camera Flash): Perfect for long-distance optical signaling or emergency beacons. Sound (Tone Generator): Adjustable frequency tones with loop playback support. Vibration (Haptics): Silent transmission using subtle device vibration pulses. Loop Playback: Keep sending your message continuously without manual intervention. 4. Guided Morse Lessons Learn Morse code step by step, from your first letters to digits and punctuation. 21 short lessons introduce two new symbols at a time, by sound, blinking light and written code. Spaced repetition brings back the symbols you are about to forget. Build a daily streak, set a daily reminder and choose your own learning speed. Lessons currently teach the English (Latin) alphabet. 5. Complete Multilingual Support Translate text and encode/decode using specialized Morse alphabets for: - English (Latin script) - Ukrainian - Japanese (Wabun Code) - Korean (SKATS) - Thai - Hindi - Hebrew - Greek - Arabic - Persian The app interface is available in 14 languages. 6.
