The UN Day SAQ transmission is approaching – so what could be a better time for an updated version of ”gerke-decoder” 🙂

The latest addition is a decoder routine based on least-squares fitting of straight line segments to the signal data, thereby locating the dashes and dots. My hope is that this could be a bit more noise insensitive than the other decoders, which all look for on/off transitions of the signal in one way or the other.

As before, try it out if you like: https://github.com/fowlay/gerke-decoder – if you have questions I will try to help, here or on github.
