Mooneer’s FreeDV Update – August 2024

This month was spent primarily assisting David with RADAE testing. Most of this involved using a web-based interface to generate a file to send out over the air (and subsequently record from a remote SDR and decode).

I also did some work on a version of freedv-gui that is able to use the existing RADAE scripts to have a two-way QSO with someone else also running the same software. So far this appears to work fine on Linux and macOS, but I am running into challenges on Windows. The main challenge is that PyTorch and/or Python seem to run significantly slower in the Windows VM that I’m using than on other platforms, which means that decoding unfortunately can’t happen in real time using this setup. I’ll investigate this further, time permitting, but it’s possible that Windows users will need to use a PC with a nVidia GPU to use the modified version of freedv-gui.

Other than that, some minor bugs and GUI tweaks were done for ezDV and freedv-gui, namely adding the configuration filename to the titlebar (for the latter) and increasing maximum HTTP header length (for the former).
