I did some experiments with denoising auto-encoders to train a neural network that can recognize Morse characters from (very) noisy input data. Jupyter Notebook source code example provided in this blogpost.

My weekend project - I built a new and improved machine learning model to train LSTM Dynamic RNN based Morse decoder. TensorFlow has improved a lot since 2015 when did similar experiments. For example variable length sequences are now possible "out-of-the-box".

@kevin
I have audio output from KX3 connected to the Behringer UCA202 USB Audio Interface. By adjusting audio volume on KX3 you can observe the Mumble Volume tuning window. KX3 can be set on any frequency where you hear a transmission, I used SSB signals to adjust the volume properly.
