Radio Amateurs Invited to Participate in the Antarctic Eclipse Festival in December

Da ARRL -

The HamSCI Antarctic Eclipse Festival in December is seeking amateur radio participation. As the shadow of the moon passes across Antarctica on December 4, it will generate traveling ionospheric disturbances that will, in turn, affect radio propagation. The unusual geometry of this year’s eclipses will give researchers an opportunity to investigate complicated ionospheric dynamics over the pole...

Pisa prima e dopo Marconi, un documentario racconta

ARI Nazionale -


La scelta dell'area pisana da parte di Marconi è una delle sue più note intuizioni e la testimonianza del metodo sperimentale da egli seguito. Tuttavia, come dimostra l'evoluzione della stazione di Coltano attraverso l'opera del Vallauri, all'intuizione seguirono studi sempre più significativi che oggi vediamo nel legame tra storia, luoghi e scienza. Nulla nasce davvero per caso. Un documentario: ''Studiare l'invisibile'', racconta mille anni di ricerca lungo le rive dell'Arno a Pisa. Da vedere, a chiusura della settimana marconiana per il 90° dell'accensione del Cristo Redentore.

Partendo da quel 12 ottobre 1931 in cui Marconi, da Roma, via Coltano, illuminò la statua del Cristo Redentore di Rio de Janeiro, il metodo sperimentale e la scienza dimostrano tutto il loro fascino. Il video documentario realizzato da DM Cultura (produzione esecutiva di Minimum Fax Media) racconta con interviste a esperti e repertori dell'Istituto Luce di Cinecittà cos'è successo, non oggi o ieri ma in mille anni.
In collaborazione con Fondazione Kainòn partecipano con interventi originali Michele Conti - Sindaco di Pisa; Prof. Alessandro Tosi - Direttore scientifico Museo della Grafica - Pisa, Prof. Giovanni Losurdo - Spokenperson dell'esperimento Virgo, Prof. Stavros Katsanevas - Direttore dell'Osservatorio Gravitazionale Europeo EGO, Fabio Cosci - Presidente Marconi Labs Coltano e il Prof. Filippo Giannetti del Dipartimento di Ingegneria dell'informazione Università di Pisa e membro del Comitato Italradio che proprio dalla palazzina marconiana di Coltano (ns.fermoimmagine) ricostruisce parte della storia della stazione radiotelegrafica attiva nei primi 40 anni del XX secolo.
Voce narrante Francesco Pannofino.

ARI-Pordenone racconta il DMR

ARI Nazionale -

Sono davvero tanti i Radioamatori italiani che da molto tempo utilizzano le radio digitali per comunicare; tra questi apparati radio troviamo quelli che utilizzano il protocollo DMR (che da tempo si affianca agli altri protocolli digitali D-STAR, C4FM e NXDN).

Il Consiglio Direttivo, sentite le nuove richieste prevenute da diversi Soci della nostra Associazione, ha pensato di riproporre le serate divulgative sull’argomento, che si terranno presso la nostra sede.

Sono state previste quattro diverse serate su questo tema, per riuscire a trattare l’argomento in modo esaustivo e poter rispondere a tutte le domande dei Soci che saranno presenti agli eventi.

Le date delle quattro serate, sono le seguenti:

  • venerdì 22 ottobre, dalle ore 21:00 alle ore 22:30;
  • venerdì 29 ottobre, dalle ore 21:00 alle ore 22:30;
  • venerdì  5 novembre, dalle ore 21:00 alle ore 22:30;
  • venerdì 12 novembre, dalle ore 21:00 alle ore 22:30.

Durante la prima di queste serate, assieme al relatore Paolo IV3BVK, impareremo a conoscere questo modo di fare radio e approfondiremo assieme i vari argomenti necessari, per poi passare alla programmazione delle radio ed effettuare successivamente i primi QSO di base.
