UVB-76, also known as “The Buzzer”, is the nickname given by radio listeners to a shortwave radio station that broadcasts on the frequency 4625 kHz.

It broadcasts a short, monotonous About this sound buzz tone, repeating at a rate of approximately 25 tones per minute, for 24 hours per day.

Here is a sample of the tone:

On very rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place. Here is one example, as archived by a researcher who monitors the frequency:

The first reports were made of a station on this frequency in 1982. Its origins have been traced to Russia, and although several theories with varying degrees of plausibility exist, its actual purpose has never been officially confirmed and remains a source of speculation.

Low-flying aircraft causing concern in Quincy

By Jessica Bartlett, Town Correspondent, Boston.com

 

A small, low-flying aircraft has been causing a fuss in Quincy this week, with many unanswered questions about what the aircraft is doing and who is operating it.

 

“It is a sanctioned flight by the FAA,” said Quincy Police Captain John Dougan, but that’s all the information he could give.

 

Dougan said the Police Department had received about half a dozen phone calls in the past week about the aircraft, which was humming loudly over residents’ heads at odd hours.

 

Despite the resident concerns, information has been limited.

 

Jim Peters, a public affairs spokesperson with the FAA, confirmed they knew about the aircraft but also declined to comment on what it was. “We’re not releasing anything beyond that,” he said. (The Full Article Source)
