On March 1, 2015 six free radio stations from Italy were in the air on different moments and each one was on air on his own QRG, transmitting a single part of a complete message in Italian and English. The challenge was recreating the complete message! The participating stations were Radio Samurai, Radio Europe, Radio Enterprise,Radio U-Boat, Mistero Ghost Planet and Radio Arcadia. The solutions you could send to radioalleanza@gmail.com. I found this a nice initiative!
