Le 18 avril, c’est la Journée mondiale des #radioamateur s !
À cette occasion, voici une surprise visuelle pleine de détails…
Dans le cadre du projet Phoenix de Fédération Open Space Makers #FOSM , et en collaboration avec lluuciole et Ema, nous mettons en avant les technologies radio – parce que le #spatial sans radio, c’est pipeau
Plusieurs clins d’œil #hamradio #satellite à chercher en plus de toutes les antennes...
