    I have uploaded a new version (2.0.1) of gerke-decoder. More filtering and decoding options are available, please see the README.md file. If you recorded one of the recent SAQ transmissions it may be fun to try and decode it. Any feedback welcome, here or on github: https://github.com/fowlay/gerke-decoder

    som svar på: SAQ transmission on October 24th 2020 (NOT FOR QSL) #8659

    Outdoor recording in Sollentuna, Sweden, JO89xk. Very damp weather and less-than-ideal antenna. Capture of the SAQ signal made directly with Audacity on laptop and exported as 44100 samples/s 16-bit mono WAV file.

    Offline analysis of the WAV file indicates that SAQ was sending at 17206 Hz?

    Using the very versatile HDSDR program (www.hdsdr.de) in CW mode I was able to write down the message of the day, after really many listenings due to poor S/N ratio. A lot of fun; thanks to all who made this possible!
