Interference over the UVB-76 frequency

 Frequency: 4625 kHz.




Pirate radio operators have been increasingly interfering with the UVB-76 frequency at night using music, whistling, and conversations.
Pirate radio operators have recently begun appearing more frequently on the 4625 kHz frequency, home to the shortwave station UVB-76. They play music, talk to one another, and create interference over the main signal, 
according to a radio monitoring researcher who runs the "UVB-76 Efir" Telegram channel-which broadcasts the station 24/7 and publishes its messages.
According to radio enthusiasts, the most active offender is the Russian-speaking "Kilohertz." "RC4," "E12," and "Sneg-05" also appear on the frequency. The extraneous signal may sound like music, whistling, or hissing, and sometimes multiple participants engage in open radio exchanges.
"The pirates' disruptive behavior is immediately noticeable because an extraneous radio signal appears on the frequency-which could be music, whistling, or hissing-while sometimes several radio hooligans conduct open conversations with each other, and some use digital modulation modes to overlay patterns and images onto the spectrogram (a visual representation of the signal - Ed.)," the researcher explained.
The pirates have their own habits. For example, before going off-air, "Kilohertz" invariably plays Viktor Tsoi's song "Quiet Night." Other participants greet listeners and wish them a good evening, or-conversely-simply switch on the music and display images on the spectrogram without a word.
