The European GNU Radio Days will be held *virtually* from June 24 to 26, 2021 with the core organizers located in Poitiers, France. The objective of the meeting is to foster collaboration between GNU Radio users, developers, hackers and enthusiasts *from all around the world* thanks to the virtual format.
As such, you are welcome to submit a presentation proposal: due to the virtual format, presentations will be recorded and broadcast with hopefully some live interaction with the speakers at the end of the presentation (similar to those who attended FOSDEM, but with humans and not a robot stopping abruptly at the end of the schedule). Demonstrations of practical use cases of GNU Radio would be favored. Registration and proposal submission (deadline: *April 15*): https://gnuradio-eu-21.sciencesconf.org/ The tentative set of tutorials is scheduled and described at https://gnuradio-eu-21.sciencesconf.org/resource/page/id/2 The third day (Saturday) will be a joint meeting with the German Software Defined Radio Academy (SDRA) with our contribution focusing on using GNU Radio for ham radio applications. Again contributions in this field will be broadcast during this joint meeting. We favor complementing the oral presentation demo with a proceeding manuscript to be uploaded to pubs.gnuradio.org if complying with the GRCon template found at https://www.gnuradio.org/grcon.tar.gz For the European GNU Radio organization committee, looking forward to meeting you virtually in June, JM -- JM Friedt, FEMTO-ST Time & Frequency, 26 rue de l'Epitaphe, 25000 Besancon, France
