I radioamatori che hanno trasformato l'ex base Nato in un museoUn gruppo di parmigiani dal 2005 hanno in concessione la stazione radio sulla cima del Monte del Giogo, tra Parma e Massa, utilizzata dagli americani durante la Guerra fredda. "Nessuna istituzione ci ha mai dato un soldo per rimettere a nuovo questo posto: è tutto frutto della nostra passionedi ENRICO MINGORIAll'ingresso, inchiodato alle robuste sbarre di metallo della cancellata, c'è un cartello: "Zona pericolosa". Il filo spinato corre minaccioso lungo l'intero perimetro dell'area, una telecamera accesa 24 ore su 24 registra qualsiasi movimento avvenga nei pressi dell'entrata. Già sul ciglio della stradina ripida e sconnessa che porta all'ingresso una scritta avvertiva: "Vietato l'ingresso". Ma disobbedendo si arriva a questo sbarramento in ferro dai tratti sinistri, sul quale si infrange il sentiero asfaltato che porta al cocuzzolo della montagna.Siamo sulla cima del Monte del Giogo, Appennino tosco-emiliano, 1.500 metri sul livello del mare. Regione Toscana, provincia di Massa Carrara, Comune di Comano. Una manciata di chilometri più giù si parla, e si produce, il parmigiano. Parma è ad un'ora di macchina, ma sono pochi, in città, a sapere che la Guerra Fredda è passata anche da questa vetta della Lunigiana, silenziosa solo in apparenza. Dall'altra parte del cancello sorge l'ex base Nato "Livorno", una tra le più importanti stazioni radio dell'Alleanza Atlantica ai tempi della contrapposizione tra i due Blocchi. Dal 1958, per oltre trent'anni, questo complesso da 20mila metri quadrati ha fatto da ponte a comunicazioni chiave sulla sorveglianza dei confini con i Paesi aderenti al Patto di Varsavia. Kennedy, Kruscev, Regan, Gorbaciov: le loro voci, e quelle dei loro generali, sono transitate anche da qui. Poi, un giorno, dall'altra parte dell'Oceano arrivò l'ordine di chiudere il presidio per far spazio ai collegamenti satellitari. Era un gelido mattino dell'inverno 1995, il Muro di Berlino era crollato da più di un lustro e i militari addetti alle apparecchiature radio lasciarono il Giogo per sempre.Da allora sono passati quasi 17 anni, ma le due coppie di antenne paraboloidi da 20 metri di diametro ciascuna sono ancora lì, sulla punta estrema del monte, a guardare da vicino il cielo e rapire gli occhi di chi entra nella base per la prima volta: enormi orecchie dell'Europa filo-americana, simbolo monumentale della civiltà delle telecomunicazioni. Due puntano verso la stazione francese di Nizza, due verso quella romana della Tolfa. C'è anche un traliccio, alto circa 25 metri, con altri due paraboloidi, più piccoli, che comunicavano con il presidio bresciano di Dosso dei Galli. Dalla Norvegia alla Turchia, erano 49 in tutto le stazioni europee rientranti nel Network Nato denominato "Ace High Troposcatter" (basato cioè sulla diffusione di onde elettromagnetiche nella Troposfera).(continua)

ACE-High, i ponti radio troposferici della Guerra Fredda finiscono su Repubblica
The Sun Today, l'attività solare non influisce sui terremoti
First let us pose the science question we wish to answer: do solar flares cause earthquakes? Note that this is more specific than asking ‘is there a relationship between solar activity and earthquakes?’. First of all, solar activity can mean flares, or coronal mass ejections, or bursts of solar wind. Here I will focus only on flares, but do bear in mind that flares and CMEs often occur in tandem. Secondly, we are asking if flares CAUSE earthquakes; not whether a LACK of flares cause earthquakes. If flares do indeed cause earthquakes then we would expect to see a positive correlation between flares occurring and earthquakes occurring. If a lack of flares cause earthquakes, then we would expect a negative (or anti-) correlation.For this experiment I have downloaded data from all known earthquakes from 1980 to the present day. This data is publicly available from the United States Geological Survey website (USGS). Here I must point out that I am not a seismologist – I have merely gathered together the dates and magnitudes of all known earthquakes greater than 4 on the Richter scale from the past 30 years. A list of all the solar flares from the last 30 years is also available from NOAA’s National Geophysical Data Center (NGDC). Below is the plot I made which shows the occurrence rate of both solar flares (in blue) and earthquakes (in red). (Anyone with a basic understanding of Excel, a little curiosity, and a bit of patience, can try this for themselves.) You can see that solar flares come and go with each solar cycle (approximately every 11 years), whereas earthquakes appear to occur continuously, with no obvious pattern.

La radio internazionale targata USA conquista 106 milioni di audience

BBG Broadcasts Reach Record Audiences
(WASHINGTON, D.C.—November 15, 2011) U.S. government funded international broadcasters reached an estimated 187 million people every week in 2011, an increase of 22 million from last year's figure, according to new audience data being made public by the Broadcasting Board of Governors.
“We are pleased that people the world over are responding in unprecedented numbers to our high-quality journalism and active audience engagement,” said BBG Chairman Walter Isaacson. “The ability of our broadcasters to inform, engage and connect audiences through traditional and social media alike lie behind these impressive results and will be essential to driving future audience reach and impact.”
The record numbers, released in the BBG Performance and Accountability Report (PAR), measure the combined audience of the Voice of America (VOA), Radio Free Europe/Radio Liberty (RFE/RL), Radio and TV Martí, Radio Free Asia (RFA) and the Middle East Broadcasting Networks (Alhurra TV and Radio Sawa). The report details impact on audiences around the globe including people in the world’s most repressive media and political environments.
The BBG’s PAR follows on the heels of BBG’s latest strategic plan, Impact through Innovation and Integration, which sets an over-arching objective of making BBG the world’s leading international news agency working to foster freedom and democracy with the goal of reaching 216 million people weekly by 2016.
This year there were significant audience increases in Afghanistan, where RFE/RL and VOA together reach 75% of adults weekly; in Egypt, where Alhurra TV doubled its weekly audience to 15% in tandem with the Arab Spring; and in Indonesia, where VOA’s aggressive affiliate strategy has boosted weekly audiences to some 38 million adults.
Audiences in many other strategically relevant countries held strong. In Nigeria, VOA retains its position as a news source of record with 23 million weekly listeners. In Burma, VOA and RFA reach 26% and 24% of adults, respectively, amounting to a weekly audience of 10 million.
Audience declines took place notably in Iran, where the government continues aggressive jamming of every BBG transmission platform, including satellite uplink jamming; and Pakistan, where the media market is increasingly fragmented and use of radio is declining.
While radio remains the BBG’s number one media platform, reaching 106 million people per week, television’s growth puts it 97 million people. The Internet audience was approximately 10 million, with the largest online audiences measured in Iraq, Russia, Indonesia, Egypt and Iran.

EeTimes: i radioamatori del XXI secolo guardano anche al passato

Ham radio in the 21st centuryHam radio today differs greatly from that of past years, but it still offers a fascinating way to explore electronics. Here’s a look at how it has changed and what it has to offer both old hands and newcomers alike.Doug Grant, K1DG -- EDN, November 3, 2011The US amateur-licensing process no longer requires knowledge of Morse code—historically, a major impediment for many individuals.The signal-processing capabilities of a sound-card-equipped PC that connects to an HF single-sideband or a VHF FM transceiver have driven the emergence of new modes.Most high-performance HF and VHF transceivers now use digital-signal-processing technology for at least some of the modulation, demodulation, and filtering functions.Ham operators have always been enthusiastic tinkerers, often building their equipment from discarded pieces of consumer electronics they find in their neighborhoods.Ham radio brings new aspects to other hobbies, such as mountaintop hiking and orienteering.Many of today’s experienced engineers got their start in electronics through amateur, or “ham,” radio. (Many theories exist over the origin of the term “ham radio,” but there is no consensus.) Over the years, however, the demands of these engineers’ work, families, and communities took precedence, and many hams lost interest and let their licenses lapse. Meanwhile, with the rise of personal communications and Internet connectivity in homes, many young engineers never needed ham radio as a way to explore electronics. They’ve missed the opportunity that this fascinating hobby presents.(continua)

Dopo 12 anni MediaCorp Singapore spegne il DAB: obsoleto

Digital Audio Broadcasting service to stop transmissionSingapore, 1 November 2011 – MediaCorp will discontinue its Digital Audio Broadcasting (DAB) service with effect from 1 December 2011.MediaCorp launched a DAB service in Singapore in November 1999 and was the first broadcaster in South East Asia to offer digital radio. Back then, DAB was widely seen as the “replacement technology” for FM radio; however, the effectiveness and reach of DAB has diminished over time with advances in technology which has widened the receptivity of radio through online streaming as well as mobile phone apps. Listeners now have a wide range of convenient access to radio alongside the FM services, which continue to provide excellent coverage and listenership in Singapore.Since the launch of the service some 12 years ago, the growth in listenership on MediaCorp’s DAB service has remained stagnant. On the other hand, the rapid growth in the number of listeners through online streaming and phone app MeRadio has shown that these platforms are serving the listeners more effectively than the DAB platform.As a commercial outfit, MediaCorp needs to channel resources where the growth engines are. Having carefully evaluated the viability of the service, the decision has been made to discontinue the service. MediaCorp will re-deploy all its DAB staff to other operations.
