Ultima Ora: Diploma 90 anni di Radio Vaticana

Causa persistenza del Covid in Italia e le situazioni di divieto alla mobilità tuttora vigenti, il prossimo 24 aprile diverse Stazioni Marconiane aderenti al Coordinamento Stazioni Marconiane Italiane non potranno essere presenti in frequenza in quanto i relativi team sono impossibilitati a raggiungere e/o ad operare dai siti marconiani dai quali solitamente trasmettono. Pertanto, per non sminuire l'importanza che merita, il Diploma dei 90 anni di Radio Vaticana viene spostato ad altra data, presumibilmente verso la fine di settembre / inizio ottobre. La data precisa sarà comunicata sempre attraverso il nostro sito e il sito del CSMI sempre sperando che la situazione Covid si sia ridimensionata per quel periodo e sia consentita la mobilità al di fuori del proprio comune di residenza. Ci scusiamo con tutti i Radioamatori e SWL che aspettavano questo evento, fino all'ultimo abbiamo sperato di poter essere "in aria" al completo con i nostri 12 team,… [...]

L'editoriale di Aprile 2021

Guardiamo oltre l'ostacolodi Vincenzo Favata, IT9IZY Il diffuso senso di partecipazione, le attività intraprese dall’attuale CDN e la scelta della strada maestra della chiarezza hanno consentito di affrontare il particolare periodo storico con relativa tranquillità. Con la speranza di poter riprendere, grazie ai vaccini, le normali attività associative non dimentichiamo che tutt’oggi permane in Lombardia - dove è ubicata la nostra sede nazionale - un notevole pericolo per la salute collettiva a causa dell’espansione delle "varianti" del coronavirus. Come ricorderete, per il disimpegno delle attività lavorative della sede di Milano è stato scelto il lavoro in smart working anche per la controllata Ediradio e RadioRivista, nonostante le restrizioni delle attività postali, è stata normalmente recapitata ai destinatari. Altro aspetto positivo che merita di essere menzionato, in questo particolare momento drammatico, è quello che concerne l’aumento dell’attività tipica dei radioamatori con l’utilizzo maggiore delle frequenze assegnate, nonostante il sostanziale periodo di… [...]

Dopo un anno di sospensione dovuta all’emergenza sanitaria dovuta al COVID-19 il 24 aprile torna, nel sabato più vicino alla data della nascita del grande genio Guglielmo Marconi che ricorre il 25 Aprile, la manifestazione radiantistica International Marconi Day (IMD) organizzata dal Cornish Amateur Radio Club. La Sezione ARI di Rapallo, essendo il Tigullio sede di esperimenti marconiani e facente parte del CSMI (Coordinamento Stazioni Marconiane Italiane) , è coinvolta direttamente con l’attivazione di stazioni aventi i nominativi speciali IY1MR (Rapallo) e IY1SM (Santa Margherita Ligure) che daranno diritto ad accumulare punti per l’ottenimento del diploma di questa 33° edizione. Le due stazioni saranno allestite a Rapallo, in località Montallegro – M. Rosa, dove Marconi svolse importantissimi esperimenti sulle microonde e a Santa Margherita Ligure presso il Grand Hotel Miramare dove il grande scienziato soggiorno a lungo e svolse anche la sua attività scientifica. L’elenco delle altre stazioni IMD sempre… [...]
