![]() ![]() The decoding algorithm uses an AGC but the waterfall sensitivity can be adjusted in the settings. Waterfall sensitivity: Some Android devices have very sensitive built in microphones others are very deaf. CAUTION: this option consumes a lot of battery power. Screen lock: Prevents the screen from turning off. Morse Decoder still decodes Morse code when the device is not directly placed at the speaker but several effects like phase interference due to echo’s or background noise can disturb the performance. To improve the performance it is recommended to place the device directly against the speaker of the radio or the device which transmit the Morse code. Morse Decoder will lock the speed and will not attempt to change the decoding speed. After Morse Decoder detected the right speed it is recommended to push the “lock speed” button. ![]() The next couple of characters could be decoded wrong. In very long breaks it is possible that Morse Decoder will detect the wrong speed. Morse Decoder will constantly determine the speed of the Morse signs. It may take several initial characters containing both dots and dashes before the WPM speed estimation acquires the actual Wpm and decodes the characters correctly. Even though Morse Decoder uses a 200Hz wide AFC (automatic frequency control) it is recommended to move the slider always on top of the vertical line. If there is a tone present the waterfall will display a blue or white vertical line (As stronger the signal as brighter the line) Slide the red rectangular on top of the vertical line. Place your Android device against the speaker of the radio or the device which transmit the Morse code. Morse Decoder can be used by Ham Radio operators or. Speeds of less than 4 Wpm (Words per Minute) to more than 50 Wpm can be decoded. Morse Decoder decodes Morse code characters through the built-in microphone of your Android device. ![]() The detected signal will be shown as a graph and several algorithms will then detect the speed of the Morse code and convert them into readable text. The DSP filter is followed by an automatic gain control (AGC) to compensate for changing signal strengths. A narrow band DSP filter can be set for the frequency of the Morse code tones by tapping the waterfall. ![]() Only by touching screen the app will play sound and decode what is handled. Morse Decoder includes a “waterfall” to show a frequency spectrum of about 50Hz to 2300Hz. Practice morse code on your mobile device using the simulator of CW Studio. Morse Decoder can be used by Ham Radio operators or anyone else interested in decoding Morse code from a Radio or any other device. You will be able to experience the best results at night or with low ambient light.Morse Decoder decodes Morse code characters through the built-in microphone of your Android device. If your device's frame rate is too slow, decoding will most certainly be impossible since at least 7 fps are required for the lowest available transmission frequency in the app.Īs the blinking light gets farther away from the phone, the decoding process gets inaccurate. Cyrillic (Russian, Serbian, Bulgarian, Ukrainian, etc) Latin alphabets (English, Spanish, Italian, Portuguese, etc.) Supported languages for transmission, decoding and translation: Supported languages (not for transmitting) Choose any of the available camera resolutions in your device. Set Day/Night mode for decoder sensibility to light. Increase sensibility to light when decoding (useful when light source is far). Includes a Morse Code International Telecommunication Union (ITU) alphabet for reference. Translate from text to Morse and vice versaĪllows translation from plain text into Morse code and translation from Morse Code to text. That is, using either the flash or the speakers. Transmit Morse code using camera flash and speaker (beeps)įor an entered message, the user can select whether to transmit the morse signal in the form of light or sound. This new setting will be saved for as long as you stay in the app. If the light blinks at a frequency that is too fast or too slow (using the default transmission settings as a comparison) expect to lose the first 2 characters, but after that, the decoding algorithm will adapt itself to the new frequency and you will lose NO more characters. Simply point the camera to the blinking light and make sure the light stays in the redĬircle. Decode Morse code using your phone camera! Transmit it using flash and speaker! ![]()
