@darc Das ist gut zu sehen, dass ich ich nicht der Einzige bin, der sich dachte, dass das Papier vollkommen kaputt ist.
Nach dem Fehlen von Ergebnissen etc. hatte ich auch keine Motivation mehr mich weiter damit zu befassen.
Es existieren bereits im Amateurfunk anwendbare Beispiele für gelernte Signalverarbeitung wie z.B. #RADE in #FreeDV.
Ich selbst habe auch schon mit neuronalen Codecs experimentiert und diese zur Sprachübertragung eingesetzt:

Danke für die Korrektur!
I've decided to go with the "Glutton For Punishment" option.
I'm going to give FreeDV another go.
I'm reinstalling Linux Mint on an ancient Acer Aspire One netbook.
It won't matter if FreeDV messes up this box because it's been in a cupboard for months anyway
It's got a tiny 10 inch screen which could make operating a slight challenge though if it does work.
Fingers crossed
I’ve been attempting to get the #freedv AppImage for #flexradio running on the RPi4 I use as my Allstar Node. I couldn’t get it to decode.
Managed to get it running on my #uconsole and received ON4LX operating on #qo100.
Spoiler: there is a firewall on the Allstar Node.

#hamradio station py2rn near Sao Paolo receives my #FreeDV transmission over #QO100 satellite
Had a short initial foray into #FreeDV yesterday- I only have a very low power antenna for 40m in the loft, so didn’t succeed with transmitting but the audio quality (on moderately high SNR signals) is impressive! The upper HF bands were empty, nobody listening, so didn’t try transmitting with moderate power there.
Wonder what the “it’s not real radio” blowhards will make of it? ;)
