Russia's mysterious 'Doomsday Radio' station has sent out another series of ominous messages, sparking fears in Europe that the nation is preparing for a broader war.
The radio channel, known as UVB-76, broadcasted multiple transmissions in code this week, sending three signals on Monday followed by eight more on Wednesday.
Each of the cryptic messages featured a set of numbers and letters, including the code words PEPPER SHAKER, TRANSFER, PABODOLL, SPINOBAZ, FRIGORIA, OPALNY, SNOPOVY, and MYUONOSVOD.
Over the last week, as many as 15 secret messages have been heard by listeners. However, their meaning and intended recipient have remained a mystery.
On Friday, the station appeared to be broadcasting the faint sound of music and prolonged bursts of Morse code.
The Russian shortwave station, nicknamed 'The Buzzer' or 'Doomsday Radio,' has been running since the 1970s, mostly playing a constant, eerie buzzing sound like a faulty appliance.
However, experts have suggested that UVB-76 is connected to Russia's strategic military command, possibly for sending secret orders to the nation's armed forces or agents operating abroad.
Typically, these mysterious codes increase in their frequency during global crises, such as the war in Ukraine, leading British Military Intelligence Service (MIS) Defense Minister Al Carns to warn that Europe may be on the brink of war.
Carns warned that the 'shadow of war is knocking on Europe's door,' adding that the UK's NATO allies must be ready to respond.
NATO Chief Mark Rutte added during a speech in Berlin Thursday that: 'Russia has brought war back to Europe, and we must be prepared for the scale of war our grandparents and great grandparents endured.'
Wednesday's massive burst of coded signals began at 1.07am ET and finished around 4.26am, according to Russian online news outlet news.ru.
State media organization Izvestia revealed on November 14 that the mysterious signal temporarily went offline after a Ukrainian drone strike damaged nearby power stations.
Following the outage, the station has been churning out waves of new messages since late November, including a concerning series of codes that included the name of the NATO country Latvia.
A batch of six messages on November 17 included one that read 'NZHTI NZHTI 15854 LATVIA 5894 4167.'
The direct naming of Latvia in the message created the most panic as tensions between Russia, Ukraine, and NATO remain dangerously high.
If Russia were to attack Latvia, it would trigger NATO's Article 5, a promise that all members of the international alliance, which includes the US, would defend each other, potentially leading to an all-out nuclear war.
One Russian-speaking listener on social media claimed that the newest batch of codes was very strange, since these signals usually come one at a time and with several days in between the next message.
'It is interesting that as many as 15 messages were sent at once, even though the usual interval is once a month or every two months,' the listener posted in English on X.
On Friday, no messages have been reported, but a continuous stream of long and short tones, often associated with Morse code have been heard on UVB-76.
Morse code is a simple way to send messages using short beeps or flashes (dots) and longer ones (dashes) with pauses between letters and words.
Military listeners who have the right codebook would be able to turn those groups into real orders or information, while everyone else just hears random letters.
It’s fast, almost impossible to jam completely, and doesn’t give away who is talking or exactly where they are, which makes it ideal for secret military communications, even in 2025.
