UVB-76: Shortwave Buzzer

UVB-76, the Russian shortwave channel that listeners call The Buzzer, is the internet's most haunting radio mystery. For decades it has droned a monotonous carrier buzz on 4625 kHz, interrupted now and then by a robotic voice reading a coded "Monolit" message: a callsign, then names and numbers. This app is an atmospheric emulator of that legendary station and its lesser-known siblings, running entirely on your device. It is not a real radio, an SDR, or a scanner. Nothing is streamed and no live signal is received. The buzz, the shortwave static and the interference are generated on your phone, and it all runs offline, no connection needed. THREE STATIONS TO TUNE UVB-76 has relatives on the shortwave band, and this app emulates three of them. Switch between them like presets on a receiver: the frequency dial retunes and the waterfall shifts. - THE BUZZER (UVB-76), 4625 kHz - the endless drone, a male voice reading "Monolit" code. - THE PIP, 5448 kHz - a short beeping marker, a female operator, its own "how do you read me" propagation checks. - THE SQUEAKY WHEEL, 5473 kHz - a two-tone squeak, a second male voice, word-and-number call-signs. Each has its own marker sound, voice and message format. WHAT YOU GET - A live waterfall spectrogram, the way a shortwave receiver's panadapter shows the station centered on 4625 kHz. - Knobs for signal, noise, interference, and drift, so you shape your own band conditions. - A message interval you set anywhere from 20 seconds to 90 days, from restless chatter to long, patient silence. - A robotic Russian voice that reads an endless supply of procedurally generated Monolit messages, spelled out in the phonetic alphabet and never quite repeating. ABOUT NUMBERS STATIONS Numbers stations are shortwave broadcasts of spoken code, widely believed to send one-way messages to agents in the field. UVB-76 is the most famous of them all, nicknamed The Buzzer for its endless drone and known in Russian as Жужжалка. Leave it running as a piece of Cold War radio atmosphere for your desk, your studio, or a long night. It is a haunted, mysterious backdrop by design, not a sleep or wellness app: the noise is the point. FAQ What is UVB-76?
