RadioRivista digitale, eccola!

Cari Soci, come promesso anche per questo mese RadioRivista si presenta a Voi con una marcia in più: la versione digitale da sfogliare on-line nell’area rigorosamente riservata a Voi iscritti. Ma con una novità rilevante. RadioRivista sarà online e quindi sfogliabile regolarmente per tutti gli iscritti, già a partire dal primo giorno di ogni mese. Un'iniziativa che ho deciso di intraprendere per garantire un servizio di informazione regolare a tutti, dato che Poste Italiane continua, nonostante i nostri ripetuti reclami e le nostre anticipate chiusure in redazione, a consegnare la rivista in forte ritardo in numerose zone del Paese. Mi auguro che questo ulteriore passo avanti venga apprezzato da tutti voi! Ricordo che RadioRivista online è resa possibile dalla preziosa collaborazione del nostro webmaster Massimiliano Laconca, IK8LOV, e che questa opportunità permette di sfogliare il magazine ufficiale dell’ARI con tutti i vostri devices. Ribadisco che questa innovazione, che rappresentava per… [...]

L'Editoriale di Dicembre

Stacchiamo l'ombra da terraGabriele Villa, I2VGW Scrivo queste righe mentre, ancora una volta, e, forse, sempre di più si sta navigando a vista nel mare dell’incertezza. Sembra oramai che i confini del mondo siano circoscritti dentro un lockdown di parole. Parole d’ordine come mascherina (con le più svariate effe dell’omologazione corretta) contagio, coprifuoco, pandemia, vaccino. Non siamo immuni, nessuno è immune. Perché non ci può esser nessuno in grado di restare immune alla tristezza di questa situazione, nessuno che non patisca queste costrizioni con angoscia, nessuno che, almeno più volte al giorno, non sia coinvolto in qualche conversazione sul tema. E’ il momento, è il tempo degli auguri certo. E li faccio a voi tutti e alle vostre famiglie con tutto l’affetto e l’amicizia di sempre perché la nostra famiglia, la famiglia dei radioamatori è talmente grande e variegata che c’è posto per l’amicizia, l’affetto e qualche volta anche per… [...]
