L'Editoriale di Settembre

Quel feeling (o filo) SpecialeGabriele Villa, I2VGW Questione di feeling. Così cantavano Mina e Cocciante un bel 35 anni fa. Che c'entra direte voi? C'entra, c'entra, fidatevi, anche se più che feeling, nel caso specifico forse sarebbe più attinente scrivere: Questione di filo. Già, perché il nostro consueto appuntamento con lo Speciale Antenne (ben 23 pagine anche questa volta!) realizzato con il prezioso contributo dei nostri collaboratori potrebbe avere come logo un filo, un semplice pezzo di filo. Quel filo semplice e innocuo con cui, da Marconi in avanti, il popolo dei radioamatori si è inventato antenne di ogni tipo dalle quali far piroettare segnali in giro per il mondo. Accrocchi improbabili a vedersi, ma precisi e puntuali nel far ascoltare la voce e i punti e le linee nitidamente, grazie alla perizia, all'ostinazione e alla fantasia di chi li aveva voluti assemblare e che, ancora oggi, con la medesima… [...]

CORCIANO: I radioamatori scelgono il Colle della Trinità per esercitazioni e il Comune pensa a future collaborazioni

Assessore Andrea Braconi, stiamo ipotizzando come integrare e potenziare i sistemi di comunicazioni sul territorio (UNWEB) Corciano. "Una situazione sulla quale stiamo ragionando e che potrebbe aprire a future collaborazioni". L'assessore all'innovazione tecnologica del Comune di Corciano, Andrea Braconi, è possibilista: dall'attività radiantistica dell'associazione Radioamatori Italiani, Sezione di Perugia – presieduta da Francesco Orfei IZ0ABD – la cui ultima esercitazione si è svolta di recente nel piazzale del Colle della Trinità, potrebbero scaturire sinergia. L'esercitazione, infatti, ha simulato uno scenario di emergenza – argomento sensibile per un ente locale - con due stazioni radio installate all'interno di una tenda alimentate da gruppi elettrogeni autonomi, per verificare la copertura radio, nell'arco delle 24 ore, su diverse frequenze assegnate al servizio di radioamatore. E' stato un lavoro complesso, che ha impegnato il gruppo fin dal mattino, con il montaggio delle strutture (antenna direttiva HF ad un'altezza di 12 metri, antenna direttiva VHF… [...]
