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… [...]

RadioRivista online per tutti

Ai Soci e..ai non Soci Cari amici, Emergenza sanitaria, ristrettezze forzate e tempo da trascorrere al meglio. Per resistere, con una carica costruttiva e propositiva, a questa surreale situazione che ci ha spiazzati, messi all'angolo. Viverlo al meglio dunque, questo tempo improvvisamente ritrovato. Progettando, lavorando, leggendo. Magari anche sfogliando la nostra RadioRivista per rimanere on air da buoni radioamatori, anche pagina dopo pagina. O per scoprire una nuova passione, il radiantismo, che possa un domani, quando saremo finalmente usciti da quest'incubo, conquistare nuovi seguaci e far loro vivere appieno quello che, proprio in circostanze come questa, dovrebbe essere il nostro esclusivo, particolarissimo ham spirit. Una premessa doverosa la mia perchè, grazie ad una decisione condivisa dall'intero Consiglio Direttivo Nazionale dell'ARI, ho il piacere di comunicarvi che,fino al numero di Settembre, continueremo ad offrire a tutti, Soci e non Soci la possibilità di sfogliare la nostra RadioRivista senza usare alcuna credenziale… [...]

Abbiamo preso questa decisione con rincrescimento ma anche con grande senso di responsabilità nei confronti dei Soci volontari, degli espositori e dei partecipanti. Cordiali 73.
