The decoding algorithm uses an AGC but the waterfall sensitivity can be adjusted in the settings.A list of the 5173 libraries registered in the Arduino Library Manager. 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. Speeds of less than 4 Wpm (Words per Minute) to more than 50 Wpm can be decoded. 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. Morse Decoder includes a “waterfall” to show a frequency spectrum of about 50Hz to 2300Hz. Morse Decoder can be used by Ham Radio operators or anyone else interested in decoding Morse code from a Radio or any other device. Morse Decoder decodes Morse code characters through the built-in microphone of your Android device.
