The pressure exerted by Russia on the former Soviet Republic is taking place on many fronts: from the military one, with the deployment of troops at the borders, to disinformation, which travels on social networks but also on the airwaves. Today the 7 MHz band, reserved for radio amateurs, is flooded with propaganda messages or messages denigrating radio operators on both sides. Francesco Cecconi discusses these messages on the Radio Hernica website, putting them into historical perspective (during the Cold War, Radio Tirana raged over the amateur radio bands). He then discusses the manoeuvres implemented by radio amateurs to counter “The Buzzer”, the Russian system that broadcasts encrypted messages on short waves, Army FM, a Ukrainian station created to counter Russian transmissions, and Vesti FM, a Russian channel broadcast from Moldavia. Audio documents with recordings of pirate broadcasts complete the in-depth analysis.
Launched in 1973 at the height of the Cold War, The Buzzer (as it has been nicknamed by radio amateurs and listeners) is a ghost radio station that has been broadcasting bizarre transmissions non-stop on 4625 kHz ever since. It broadcasts a sonar-like sound, interspersed with pauses, the purpose of which is not known; sometimes short voice messages in Russian are broadcast. Over the years, the community of radio amateurs and listening enthusiasts has monitored the transmissions and found technical flaws, such as when in 2010 the transmissions were interrupted for a day and two days later voices were heard in the background, as if a microphone had been left open. The Infinity News article reconstructs the history of “The Buzzer”, while other details can be found on Wikipedia.
