Did you know that the airwaves are full of strange radio signals? Some come to us from space, others have a natural or man-made source on Earth. However, the origin of some of the signals cannot be traced. Among those who watch such broadcasts, there is also the organization ENIGMA 2000 (its name stands for "European Association for Tracking and Collecting Information about Number Stations").
Ping
In November 2016, residents of the far north of Canada began to complain of a loud buzz coming from the depths of Fury and Heckle, which also significantly disturbed local animals. The Canadian military is currently investigating the source of the strange signal.
Backward Music Station (ENIGMA Identifier - XM)
In fact, this signal only resembles music played backwards. The broadcast has two sources - one in Europe, the other in the United States. Observers have noticed that the US Navy is using the same frequencies, but so far no one has figured out what it is.

Mixer (ENIGMA identifier - XF)
It got its name due to the fact that the signal either faded or gained strength. Disappeared suddenly in 2001 after nearly 30 years of broadcasting. It was believed that its source was located on the territory of the British military airbase Mildenhall, and the signal itself was part of the secret communications system of NATO command centers. Some observers believe that the exchange of these signals has been carried over to satellites.
Intrusion into the broadcast of the TV channel WGN-TV
The story began with the 80s TV character Max Headrum, who voiced advertisements and even hosted his own TV show. In fact, Max was one of the first representatives of artificial intelligence. So, in November 1987, someone interrupted the broadcast of the WGN-TV channel, saying that he was Max Headrum. There was no sound, only a face and a running line of subtitles with meaningless phrases. The craziest part of this whole incident is that the broadcast violator was never caught.
Buzzbox (Identifier according to ENIGMA classification - S28)
This low quality signal has been reproduced since at least 1982. Most often it sounds like a dull hum, but its oddity lies in the fact that over the past 40 years, the hum has been interrupted three times. At these moments, a male voice pronounced names in Russian.
Vrillon
On November 26, 1977, a UK Southern Television news broadcast was interrupted by a message in which a strange mechanical voice claimed to be an alien named Vrillon from the Ashtar Galactic Command. To this day, the intruder has not been found.
Bulk
The so-called Bulk is a powerful low frequency signal noticed by the National Oceanic and Atmospheric Administration (NOAA) in 1997. The two main theories for the origin of the signal are either a large marine animal or an iceberg grazing the ocean floor. The source is located somewhere in the region of latitude 50 ° S and longitude 100 ° E, that is, in the remote part of the ocean between South America and Antarctica.
Workshop (Identifier according to ENIGMA classification - XW)
This signal was picked up by radio amateurs only a few times. It sounds like a microphone forgotten in a workshop - footsteps, knocking, and distant conversations in Russian are heard.
Handy Manny
In 2007, the Disney TV cartoon show was interrupted by the broadcast of hardcore porn. The cable TV company found itself at the center of a major scandal after the incident, but the attacker was never identified.
Precision time signals (Identifier according to ENIGMA classification - M21)
On this wave, a repeating signal of 14 digits and a time stamp is caught every 50 seconds. Most often, he reports the time GMT + 4, but there are also +2, +3 and +8. Since all of these time zones are located on Russian territory, observers believe that the signal is coming from Russian air defense facilities.
Slot machine (Identifier according to ENIGMA classification - XSL)
The signal, consisting of a series of high pitched sounds very much like the sound of a slot machine, is best picked up in the Far East. Observers believe that the source of the signal may be the Imperial Japanese Navy.
Meow
The constant meowing signal was available around the clock until the early 2000s.
Wop-wop (Identifier according to ENIGMA classification - XWP)
Sounds very similar to the slow motion recording of shots from a machine gun. The signal is best heard in southern England. Observers believe it is part of the French tide and other maritime weather system.
Squeaker (Identifier according to ENIGMA classification - S30)
Like the Buzzbox, the signal consists of a constant squeaking sound, periodically interrupted by a male voice pronouncing messages in Russian. For example: “For 854 032 471 331 629 008. How do you hear? Reception.
"Wow!" signal
This signal was recorded with the Ohio State University Big Ear radio telescope. The source was located in space near the constellation Sagittarius, the duration was 72 seconds. Astronomer Jerry Eiman was so amazed that he left a "Wow!" and this name was stuck with an incomprehensible signal.
For a long time the mystery remained unsolved, and recently physicists suggested that the source could be hydrogen clouds emitted by two comets passing relatively close to us. However, not the entire scientific community is satisfied with this answer.
