Show activity on this post. I am trying to write a Python script that can demodulate an FSK modulated audio file and return the data encoded in the audio. The data being transmitted is GPS NMEA strings which are embedded as the audio channel in video files. Basically, text is encoded with FSK modulation, and I am trying to retrieve the text ...

[APRS FSK Demodulation] How do I measure frequencies ...

https://forum.arduino.cc/t/aprs-fsk-demodulation-how-do-i-measure-frequencies-accurately-in-one-cycle/369832

[Intro]: So I would like to build an APRS demodulator/decoder it is an Audio FSK signal. I have the basic idea of what I need to do, and right now I am focusing on the detection of the mark and space [1, 0] respectively, essentially working on this project in “blocks”. [Requirements]: I need to capture the frequency either 1200/2200Hz signals and report them as …
