L'Editoriale di Gennaio

ARI: sempre al servizio dei Socidi Vincenzo Favata, IT9IZY In questo periodo di restrizioni imposte dai protocolli sanitari per il contenimento della pandemia da Covid-19, per superare il disagio provocato dalle limitazioni dei movimenti delle persone sul territorio, da qualche mese immagino - forse inconsciamente - con una certa frequenza, di trovarmi davanti ai cancelli di una grande “Mostra del Radioamatore” una delle più importanti d’Italia; un pensiero che scalda il cuore a chi, come me, ha una grande passione per la radio e il mondo del radiantismo. Dopo l’esaurimento delle ondate pandemiche, le fiere radioamatoriali e la ripartenza di tutte le attività saranno una realtà che consentirà la realizzazione di desideri - come quello sopra citato - che credo siano ricorrenti nella mente dei radioamatori.

Basti pensare a quando il grande scienziato, dalla cabina radio dell’Elettra - ancorata nel porto di Genova - tramite un segnale radio accese le luci del Municipio di Sydney, dall'altra parte del pianeta. O ancora, la navigazione cieca nel golfo del Tigullio, effettuata tramite radiofaro; senza dimenticare gli esperimenti sul radar e le trasmissioni tramite microonde. Non a caso, quindi, il poeta Gabriele D’Annunzio definì Elettra “candida nave che naviga nel miracolo e anima i silenzi del mondo”. Il Diploma… [...]
