Novità dal MIMIT

Lo scorso 30 novembre la nostra Associazione presentò al MIMIT un articolato documento nel quale, fra l’altro, s’invitava il Ministero a considerare l’attribuzione temporanea su base annuale al servizio di Radioamatore - in deroga al PNRF - delle bande dei 4 e 8 metri, nonché l’estensione della banda 160 metri. Questa mattina, venerdì 30 agosto, con note prot. 67210 e prot. 67221, il MIMIT ci ha comunicato che a seguito della nostra richiesta decise di avviare una consultazione con lo Stato Maggiore della Difesa (a cui tali frequenze sono assegnate). Sulla base dei pareri espressi sono state autorizzate - in base di non interferenza - in via generale e temporanea, fino al 31 dicembre 2024, sull’intero territorio nazionale, sperimentazioni per scopi radioamatoriali di propagazione nelle bande di frequenza richieste. Le note di cui sopra indicano le modalità di utilizzo, e sono già state inviate ai Comitati Regionali e alle Sezioni [...]
