You can also try to solve some Morse Puzzles yourself - https://deepmorse.com/select/ - or check this out https://deepmorse.com/matrix - this view gives different speed / SNR combinations.

I am currently running experiment where I train the model with different speed/SNR combinations of Morse audio files. A standalone application that would accept IQ samples may be feasible with some extra work; right now it only accepts 8 kHz WAV file samples for training and validation audio files. <br /><br />Integrating to FLDIGI may be feasible as Tensorflow does have C++ API, but I have not spent any time looking at that yet. <br /><br />In terms of CPU power the training obviously takes a lot of time and CPU power, whereas the inference should be significantly less. I haven't done any measurements yet but the Python code is in Github and freely available so such an experiment. <br />73 <br />Mauri, AG1LEag1lehttps://www.blogger.com/profile/16415319751367496314noreply@blogger.comtag:blogger.com,1999:blog-3326773214329183284.post-27562721814706983292019-02-07T07:48:22.685-05:002019-02-07T07:48:22.685-05:00Hi Mauri,

Do you have some comparison on how much CPU power such a machine learning morse decoder needs in comparison to "traditional" decoders?<br />Do you plan some plattform that can be used for average people for testing (e.g. re-integration in FLDIGI, or make a standalone application that can accept IQ samples)?<br /><br />73<br />Mario, DH5YMDh5ymhttps://www.blogger.com/profile/00056512756904748019noreply@blogger.com
