FOSDEM is a free event for software developers from all over Europe to meet, share ideas and collaborate and it held this year in Brussels on the 1st & 2nd of February 2025.
Out of the 1000+ lectures, a few were radio related...
Using AI hardware accelerators for real-time DSP on embedded devices - NPU, TPU etc,
M17 and OpenRTX: one year later
The AFF3CT framework for building numerical communication chains
HAMNET - Status Update
RF Swift: A Swifty Toolbox for All Wireless Assessments
SDR++, a modular, cross-platform SDR utility
Broadband data transfer over USB for GNU/Linux: 1-2 GHz (L-band) SDR receiver
Meshtastic - off-grid communication for everyone
Yet another new SDR runtime?
Some of these talks have slides available in PDF format and there are links if you want to explore the subject more.
The links to each radio talk can be found here... https://fosdem.org/2025/schedule/track/radio/
Here are three subjects that I found of interest.
1) HAMNET...
HAMNET is a Highspeed Amateur Radio Multimedia NETwork developed from an experiment into a stable infrastructure, particularly in German-speaking countries. It generally connects unmanned amateur radio stations via microwave links using the IPv4 and BGP protocols and provides a platform for networking amateur radio applications.
The slides for this talk can be found HERE
2) M17...
M17 is an open source protocol for digital radio and its goal is to allow radio amateurs to communicate via digital voice and data. The M17 team are also developing open source hardware in conjunction with this. The net result is to have hardware and software that is designed for the amateur radio community and is not dependant on commercial companies or third parties. In other words, M17 is designed by radio amateurs for radio amateurs.

3) Meshtastic...
