RadioRivista sfogliabile (ma solo ai Soci)

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 Maggio 2021

L'innocua rivoluzione possibileGabriele Villa, I2VGW Scrivo queste righe in bilico tra un rosso e un arancione, nell’augurarmi, come tutti noi che presto si sfumi nel giallo e quindi nel bianco definitivo. Non sono, purtroppo,come abbiamo ormai imparato, i colori dei ghiaccioli di un tempo, ma sono il nuovo tempo, scandito da zone, confini, distanziamenti, mascherine, diffidenze e vaccini. Eppure. Eppure noi radioamatori siamo riusciti, in tutto questo periodo, nella magica alchimia di non sentirci isolati e di non far sentire isolato il resto del mondo fuori dalla nostra porta di casa. A patto, ovviamente, che il resto del mondo avesse almeno un filo a far d’antenna alla propria e lecita voglia di comunicare. In buona sostanza dovremmo essere orgogliosi per tutto ciò che molti di noi sono riusciti ad inventarsi per “stay at home” senza imbruttirsi, senza deprimersi e senza egoisticamente chiudersi nelle sterili invettive contro un nemico subdolo quanto… [...]
