Dear GNU Radio enthusiasts, as part of the virtual event European GNU Radio Days to be held June 24--26, 2021 as a joint meeting with the Software Defined Radio Academy for the Saturday session, our generous sponsor NI is donating two B205mini. A challenge has been set to select the winners amongst the participants, as provided at https://gnuradio-eu-21.sciencesconf.org/resource/page/id/3
The first two best entries will be offered the B205mini units selected on the provided answers. Best wishes and good luck, for the European GNU Radio Days organizing committee, JM -- JM Friedt, FEMTO-ST Time & Frequency, 26 rue de l'Epitaphe, 25000 Besancon, France
