The Conet Project - Recordings of Shortwave Numbers Stations [ird059] : Free Download & Streaming : Internet Archive

6955 kHz{Information Encoding}

That's Right, I'm a Fringe Fan! But, I have to say... I'm not a boy! I am a Man! And an Old one at that;) If you don't know what Fringe is... It's one of my Favorite TV Shows. It's a SciFi show about Fringe Science. 6955 kHz is the title of this weeks episode and this Post is the research I did on Numbers stations (or number stations) which are shortwave radio stations of uncertain origin. After watching this intriguing episode about these shortwave broadcasts.

Aired: 11/11/10

Episode Summary:
Several people simultaneously suffer from amnesia while listening to a mysterious radio broadcast listing numbers. Once the Fringe team discovers a device from the alternate universe that inserted a special signal into the broadcast to trigger the amnesia, they work to determine why the device was deployed. By piecing together different bits of information, the team is able to decode the secret of the numbers broadcasts and understand why agents from the alternate universe were trying to prevent its discovery.

I'm an audio buff. But more into Live Audio and Recording. I've never learned much about Shortwave Radio. Even though I have an Amateur Radio Operators Licence. But, I got mine for a job as a Master Control Operator for a TV Station. You have to have a licence to do that job.

So, here's what I found out...

The Conet Project - Recordings of Shortwave Numbers Stations [ird059] ()

For more than 30 years the Shortwave radio spectrum has been used by the worlds intelligence agencies to transmit secret messages. These messages are transmitted by hundreds of Numbers Stations.

Shortwave Numbers Stations are a perfect method of anonymous, one way communication. Spies located anywhere in the world can be communicated to by their masters via small, locally available, and unmodified Shortwave receivers. The encryption system used by Numbers Stations, known as a one time pad is unbreakable. Combine this with the fact that it is almost impossible to track down the message recipients once they are inserted into the enemy country, it becomes clear just how powerful the Numbers Station system is.

These stations use very rigid schedules, and transmit in many different languages, employing male and female voices repeating strings of numbers or phonetic letters day and night, all year round.

The voices are of varying pitches and intonation; there is even a German station (The Swedish Rhapsody) that transmits a female child's voice!

One might think that these espionage activities should have wound down considerably since the official end of the cold war, but nothing could be further from the truth. Numbers Stations (and by inference, spies) are as busy as ever, with many new and bizarre stations appearing since the fall of the Berlin wall.

Why is it that in over 30 years, the phenomenon of Numbers Stations has gone almost totally unreported? What are the agencies behind the Numbers Stations, and why are the eastern European stations still on the air? Why does the Czech republic operate a Numbers Station 24 hours a day? How is it that Numbers Stations are allowed to interfere with essential radio services like air traffic control and shipping without having to answer to anybody? Why does the Swedish Rhapsody Numbers Station use a small girls voice?

These are just some of the questions that remain unanswered.

Now you will be able to hear this unique and extraordinary phenomenon for yourself, as Irdial-Discs releases THE CONET PROJECT: the first comprehensive collection of Numbers Stations recordings released to the public.

This Quadruple CD is an important historical reference work for research into this hitherto unreported and unknown field of espionage. The CDs contain 150 recordings spanning the last twenty years; taken from the private archives of dedicated shortwave radio listeners from around the world.

There's more information in the included PDF booklet and via the official site for this 4xCD collection.

Numbers station

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Numbers stations (or number stations) are shortwave radio stations of uncertain origin. They generally broadcast artificially generated voices reading streams of numbers, words, letters (sometimes using a spelling alphabet), tunes or Morse code. They are in a wide variety of languages and the voices are usually female, though sometimes male or children's voices are used.
Evidence supports popular assumptions that the broadcasts are used to send messages to spies. This usage has not been publicly acknowledged by any government that may operate a numbers station, but in 2001, the United States tried the Cuban Five for spying for Cuba. The group had received and decoded messages that had been broadcast from a Cuban numbers station.^[1] Also in 2001, Ana Belen Montes, a senior US Defense Intelligence Agency analyst, was arrested and charged with espionage. The federal prosecutors stated: "Montes communicated with the Cuban Intelligence Service through encrypted messages and received her instructions through encrypted shortwave transmissions from Cuba”. In 2006, Carlos Alvarez and his wife, Elsa, were arrested and charged with espionage. The U.S. District Court Florida stated: "defendants would receive assignments via shortwave radio transmissions”. In June 2009, the United States similarly charged Walter Kendall Myers with conspiracy to spy for Cuba and receiving and decoding messages broadcast from a numbers station operated by the Cuban Intelligence Service to further that conspiracy.^[2]^[3]
It has been reported that the United States uses numbers stations to communicate encoded information to persons in other countries.^[1]

[edit] Suspected origins and use

According to the notes of The Conet Project,^[4] numbers stations have been reported since World War I. If accurate, this would make numbers stations among the earliest radio broadcasts.
It has long been speculated, and was argued in court in one case, that these stations operate as a simple and foolproof method for government agencies to communicate with spies working undercover.^[5] According to this theory, the messages are encrypted with a one-time pad, to avoid any risk of decryption by the enemy. As evidence, numbers stations have changed details of their broadcasts or produced special, nonscheduled broadcasts coincident with extraordinary political events, such as the August Coup of 1991 in the Soviet Union.^[6]
Number Stations are also acknowledged for espionage purposes in Robert Wallace and H. Keith Melton's Spycraft (p. 438):^[7]

The one-way voice link (OWVL) described a covert communications system that transmitted messages to an agent's unmodified shortwave radio using the high-frequency shortwave bands between 3 and 30 MHz at a predetermined time, date, and frequency contained in their communications plan. The transmissions were contained in a series of repeated random number sequences and could only be deciphered using the agent's one-time pad. If proper tradecraft was practiced and instructions were precisely followed, an OWVL transmission was considered unbreakable. [...] As long as the agent's cover could justify possessing a shortwave radio and he was not under technical surveillance, high-frequency OWVL was a secure and preferred system for the CIA during the Cold War.

Others speculate that some of these stations may be related to illegal drug smuggling operations.^[8] Unlike government stations, smugglers' stations would need to be lower powered and irregularly operated, to avoid location by triangulated direction finding, followed by government raids. However, numbers stations have transmitted with impunity for decades, so they are generally presumed to be operated or sponsored only by governments. Also, numbers station transmissions in the international shortwave bands typically require high levels of electric power that is unavailable to ranches, farms, or plantations in isolated drug-growing regions.
High frequency radio signals transmitted at relatively low power can travel around the world under ideal propagation conditions, which are affected by local RF noise levels, weather, season, and sunspots, and can then be received with a properly tuned antenna of adequate size, and a good receiver. However, spies often have to work only with available hand held receivers, sometimes under difficult local conditions, and in all seasons and sunspot cycles.^[9] Only very large transmitters, perhaps up to 500,000 watts, are guaranteed to get through to nearly any basement-dwelling spy, nearly any place on earth, nearly all of the time. Some governments may not need a numbers station with global coverage if they only send spies to nearby countries.
Although no broadcaster or government has acknowledged transmitting the numbers, a 1998 article in The Daily Telegraph quoted a spokesperson for the Department of Trade and Industry (the government department that, at that time, regulated radio broadcasting in the United Kingdom) as saying, "These [numbers stations] are what you suppose they are. People shouldn't be mystified by them. They are not for, shall we say, public consumption."^[10]
On some stations, tones can be heard in the background. It has been suggested that in such cases the voice may be an aid to tuning to the correct frequency, with the coded message being sent by modulating the tones, perhaps using a technology such as burst transmission.
The use of number stations as a method of espionage is discussed in Spycraft (p. 37):^[7]

The only item Penkovsky used that could properly be called advanced tradecraft was his 'agent-receive' communications through a one-way voice-link. These encoded messages, known as OWVL, were broadcast over shortwave frequencies at predetermined times from a CIA-operated transmitter in Western Europe. Penkovsky listened to these messages on a Panasonic radio — strings of numbers read in a dispassionate voice — and then decoded them using a one-time pad.

[edit] Identifying and locating

Numbers stations are often given nicknames by enthusiasts, often reflecting some distinctive element of the station such as their interval signal. For example, the "Lincolnshire Poacher", formerly one of the best known numbers stations (generally thought to be run by MI6, as its transmissions have been traced to RAF Akrotiri in Cyprus), played the first two bars of the folk song "The Lincolnshire Poacher" before each string of numbers. "Magnetic Fields" plays music from French electronic musician Jean Michel Jarre before and after each set of numbers. The "Atención" station begins its transmission with the Spanish word "¡Atención!"
Although it is time-consuming and may require costly global travel to pinpoint the source of a radio transmission in the shortwave band, errors at the transmission site, radio direction-finding, and a knowledge of shortwave radio propagation have provided armchair detectives clues to some number station locations.
For example, the "Atención" station was thought to be from Cuba, as a supposed error allowed Radio Habana Cuba to be carried on the frequency.^[11] Whether the frequency of Radio Habana Cuba and the frequency of the "Atención" station merely interfered with each other or whether the operator of the station was listening to the radio and it accidentally ended up on the air is unclear.
Also, several articles in the radio magazine Popular Communications published in the 1980s and early 1990s described hobbyists using portable radio direction-finding equipment to locate numbers stations in Florida and in the Warrenton, Virginia, areas of the United States.^[12] From the outside, they spotted the station's antenna inside a military facility. The station hunter speculated that the antenna's transmitter at the facility was connected by a telephone wire pair to a source of spoken numbers in the Washington, D.C., area. The author said the Federal Communications Commission would not comment on public inquiries about American territory numbers stations.

[edit] The Atención spy case evidence

Atención of Cuba became the world's first numbers station to be officially and publicly accused of transmitting to spies. It was the centerpiece of a United States federal court espionage trial following the arrest of the Wasp Network of Cuban spies in 1998. The U.S. prosecutors claimed the accused were writing down number codes received from Atención, using Sony hand-held shortwave receivers, and typing the numbers into laptop computers to decode spying instructions. The FBI testified that they had entered a spy's apartment in 1995, and copied the computer decryption program for the Atención numbers code. They used it to decode Atención spy messages, which the prosecutors unveiled in court.
United States government evidence included the following three examples of decoded Atención messages.^[13] (Not reported whether the original clear texts were in Spanish, although the phrasing of "Day of the Woman" would indicate so.):

"prioritize and continue to strengthen friendship with Joe and Dennis" [68 characters]
"Under no circumstances should [agents] German nor Castor fly with BTTR or another organization on days 24, 25, 26, and 27." [112 characters] (BTTR is the anti-Castro airborne group Brothers to the Rescue)
"Congratulate all the female comrades for International Day of the Woman." [71 characters] (Probably a simple greeting for March 8, International Women's Day)

At the rate of one spoken number per character per second, each of these sentences takes a minute or more to transmit.
The moderator of an e-mail list for global numbers station hobbyists claimed "Someone on the Spooks list had already cracked the code for a repeated transmission [from Havana to Miami] if it was received garbled." Such code-breaking is possible if a one-time pad decoding key is used more than once.^[14]

[edit] Formats

Generally, numbers stations follow a basic format, although there are many differences in details between stations. Transmissions usually begin on the hour or half-hour.
The prelude or introduction of a transmission (from which stations' informal nicknames are often derived) includes some kind of identifier, either for the station itself and/or for the intended recipient. This can take the form of numeric or radio-alphabet "code names" (e.g. "Charlie India Oscar", "250 250 250"), characteristic phrases (e.g. "¡Atención!", "1234567890"), and sometimes musical or electronic sounds (e.g. "The Lincolnshire Poacher", "Magnetic Fields"). Sometimes, as in the case of the Israeli radio-alphabet stations, the prelude can also signify the nature or priority of the message to follow (e.g.(hypothetically) "Charlie India Oscar-2", indicating that no message follows). Often the prelude repeats for a period before the body of the message begins.
There is usually an announcement of the number of number-groups in the message, then the groups are recited. Groups are usually either four or five digits or radio-alphabet letters. The groups are typically repeated, either by reading each group twice, or by repeating the entire message as a whole.
Some stations send more than one message during a transmission. In this case, some or all of the above process is repeated, with different contents.
Finally, after all the messages have been sent, the station will sign off in some characteristic fashion. Usually it will simply be some form of the word "end" in whatever language the station uses (e.g. "end of message, end of transmission"; "Ende"; "fini"; "final"; "konets"). Some stations, especially those thought to originate from the former Soviet Union, end with a series of zeros, e.g. "000 000"; others end with music or other sundry sounds.
Because of the secretive nature of the messages, the cryptographic function employed by particular stations is not publicly known, except in one or possibly two cases.^[15] It is assumed that most stations use a one-time pad that would make the contents of these number groups indistinguishable from randomly generated numbers or digits. In the one definitely known case, West Germany did use a one-time pad for numbers transmissions.^[16]

[edit] Transmission technology

Although few numbers stations have been tracked down by location, the technology used to transmit the numbers has historically been clear — stock shortwave transmitters using powers from 10 kW to 100 kW.
Amplitude modulated (AM) transmitters with optionally variable frequency, using class-C power output stages with plate modulation, are the workhorses of international shortwave broadcasting, including numbers stations.
Application of spectrum analysis to number station signals has revealed the presence of data bursts, RTTY-modulated subcarriers, phase-shifted carriers, and other unusual transmitter modulations like polytones.^[17] (RTTY-modulated subcarriers were also present on some U.S. commercial radio transmissions during the Cold War.^[18])
The frequently reported use of high tech modulations like data bursts, in combination or sequence with spoken numbers, suggest transmissions for differing intelligence operations.^[19]

Speech/Morse generator

For spies in the field, low tech spoken number transmissions continue to have advantages in the 21st century. High tech data receiving equipment is difficult to obtain,^[20] and being caught with more than a civilian shortwave news radio could be construed as evidence of spying. Yet governments' embassies, aircraft, and ships at sea are known to possess complex receiving equipment that could make regular use of encrypted data transmissions from the home country. These probably include charts and photos that require more transmitted data than can be sent efficiently using spoken numbers.

[edit] The USSR and superpower number stations

During the Cold War there was substantial evidence from the amateur radio community that the USSR may have been using transmitters to reach agents in Western Europe, North Africa, and possibly North America with output power ranging up to 500 kW. HF direction finding evidence that was collected by many different sets of amateurs in Europe, Africa, and the Americas during the Cold War substantiates number stations broadcasting from the East of the Urals.
USSR technical literature shows that the USSR pioneered HRS 8/8/1 directional HF antennas for shortwave news and information broadcasting in the late 1960s–mid 1970s. Thus it is possible that lower transmitter powers (like 100 kW) were used in the 1980s (late Cold War) for numbers station use.

[edit] Interfering with numbers stations

[edit] Documented instances of interference to broadcasts

The North Korean foreign language service Voice of Korea began to broadcast on the Lincolnshire Poacher's former frequency, 11545 kHz, in 2006, possibly to deliberately interfere with its propagation. This clash can be viewed in video format. The apparent target zone for the Lincolnshire Poacher signals originating in Cyprus was the Middle East, not the Far East which is covered by its sister station Cherry Ripe.
On 27 September 2006, amateur radio transmissions in the 30 m band were affected by the E7 "Russian Man" number station at 1740 UTC. The interference can be heard here.
The late "Havana Moon" reported in his own publication "The Numbers Factsheet" in October 1990 that "one particularly dangerous station has been interfering with air to ground traffic on 6577 kHz, a frequency allocated to international aeronautical communications in the busy Caribbean sector". "On at least one monitored transmission, the air traffic controller at ARINC moved the pilot to an alternate frequency as the numbers transmission was totally blocking the frequency from effective use".
A station operated by the West German BND agency whose callsign was "Hotel Kilo" used to transmit on 9450 kHz, interfering with Radio Moscow (now The Voice of Russia) which used the same frequency. A tape recording of the interference was submitted to Radio Moscow which prompted this response.
SW Radio Africa transmits from Meyerton, South Africa, on 4880 kHz and is the "Independent Voice of Zimbabwe". A video of the Mossad E10 station "Uniform Lima X-Ray" interfering with the African station.
The religious station WYFR transmits from Okeechobee, Florida, USA, on 6855 kHz. It is regularly affected by the Cuban Spanish number station "V2". A video shows the V2 interfering with the American station.
A BBC frequency, 7325 kHz, has also been used. This prompted a letter to the BBC from a listener in Andorra. She wrote to the World Service "Waveguide" program complaining that her listening had been spoiled by a female voice reading out numbers in English and she asked the announcer what this interference was. The BBC presenter laughed at the suggestion of spy activity. He had consulted the experts at Bush House (BBC World Service headquarters) who declared that the voice was reading out nothing more sinister than snowfall figures for the ski-slopes near the listener's home. With more research into this case, short wave enthusiasts are fairly sure that this was a numbers station being broadcast on a random frequency.^[21] The likelihood of the broadcast being snow readings is in doubt because it would have been illegal to broadcast on an already used frequency.
Radio Ukraine International uses 9950 kHz in the 31 metre band. At 1610 UTC on Thursday 22 November 2007, the powerful S06 Russian number station transmitted a call up of "425".
Radio Mediterranee Int. (Medi 1) transmits on 9575 kHz from Nador, Morocco. On 11 September 2008, the English language number station E11a sent a message on 9576 kHz, which was hidden in the upper sideband of the Moroccan station.

[edit] Attempted jamming of number stations

Numbers station transmissions have often been the target of jamming attempts. Despite this targeting, many number stations continue to broadcast unhindered. Several theories exist that aid in explaining the inability to effectively jam the transmissions. With only a finite number of jamming transmitters available at any given time, it may be more efficient to block clandestine stations intended for a large audience rather than a message intended for a single person. Another theory is that there may be a "gentlemen's agreement" in place; i.e. "We won't jam yours if you don't jam ours". In addition, the haphazard nature of some stations, e.g. not having a fixed schedule or frequency, also makes jamming more difficult because the broadcast may go undetected.
Historical examples of jamming:

The E10 YHF being jammed by the mysterious "Chinese Music Station". This jammer has been dubbed the Chinese Fire Dragon Jammer and purportedly comes from Hainan Island which is located in the Gulf of Tonkin and is a part of the People's Republic of China.^[22]
The E3 Lincolnshire Poacher station was at one time in the early 1990s the target for "bubble" or "warble" jammers. In this example, the jammer appears to be in some difficulty.
The E5 CIA station dubbed "Cynthia" by number station monitors has also been the target of the same type of jamming as the above example.
On 2 September 2008 at 1700 UTC on 9130 kHz, the E10 Mossad station EZI 1 was being jammed whereas its parallel frequency of 6840 kHz was in the clear.

[edit] Classification

Although most number stations have various nicknames which usually describe some aspect of the station itself, the ENIGMA 2000 number stations monitoring group has assigned a code to each known station, this takes the form of a letter followed by a number (or, in the case of some "X" stations, more letters). The letter indicates the language used by the station in question:

E indicates a station broadcasting in English.
G indicates a station broadcasting in German.
S indicates a station broadcasting in a Slavic language.
V indicates all other languages.
M is a station broadcasting in Morse Code.
X indicates all other transmissions such as polytones in addition to some unexplained broadcasts which may not actually be numbers stations.
T indicates a station broadcasting in an unknown language.

For example, the well known, defunct Lincolnshire Poacher station has the designation E3 (or E03), the Cuban "Atención" station has designation V2 (or V02). The most recent station to be given a designation is M94, which is believed to be sent from South Korea.
Some stations have also been stripped of their designation if they are discovered not to be a numbers station. This was the case for E22 which was discovered in 2005 to be test transmissions for All India Radio.

[edit] In popular culture

In an episode of the USA Network series Covert Affairs, a child genius deciphers the numbers being transmitted from a station, and goes to the CIA for help. The episode contained The Lincolnshire Poacher as the fictional station's interval signal.
Two songs, 'Even Less' from the band Porcupine Tree and 'A Half Built House' from the band We Were Promised Jetpacks feature a number station broadcast prominently. 'No Station' by 65daysofstatic is an extensive remix of the Lincolnshire Poacher station. The Submarines song "Submarine Symphonika" and the Stereolab song "Pause" both use the Swedish Rhapsody Numbers station.
American band Wilco's record Yankee Hotel Foxtrot (2001) was named after a series of letters in the phonetic alphabet that singer/songwriter front-man Jeff Tweedy had heard on the Irdial box set The Conet Project: Recordings of Shortwave Numbers Stations. On the fourth track of the album, "Phonetic Alphabet - Nato" a woman repeats the words "Yankee Hotel Foxtrot" numerous times; a clip from this track was placed in the Yankee Hotel Foxtrot song "Poor Places." Irdial sued Wilco for copyright infringement, and a settlement was reached out of court.
Scottish electronic duo Boards of Canada's track "Gyroscope" from Geogaddi contains samples of a numbers station sampled by Sean Booth of Autechre, as confirmed by a representative of Hexagon Sun on the WATMM forum.
The Soviet TV miniseries Seventeen Moments of Spring (1973) features the protagonist spy Stirlitz receiving orders through numbers broadcasts and decoding the messages using a book.
The television show Lost features a storyline in which the character Hugo "Hurley" Reyes wins the lottery. The numbers he used (4 8 15 16 23 42) came from a fellow patient at the mental hospital in which Reyes had previously been admitted. That patient had been stationed at a military listening outpost many years earlier. He heard the numbers from a radio transmission (albeit a long-wave transmission, not shortwave) which was repeating the numbers on a loop. The transmission came from the island itself.
The BBC show Spooks has Russia's Federal Security Service transmitting a secret broadcast through a numbers station to a sleeper agent who targets Grosvenor Square in London which is home of the United States embassy.^[23]
In the film Vanilla Sky Cameron Crowe used samples of recordings from The Conet Project in certain scenes of the film. He said he used the station recordings to create a sense of confusion.
In episode S03E06 of Fringe entitled "6995 kHz," a mysterious transmission from an unknown numbers station causes a group of enthusiasts to immediately develop retrograde amnesia. The number station used in the start is a remake of the famous Swedish Rhapsody. Hidden in the transmission is a pulse frequency that causes the amnesia. This is part of the overarching storyline. The series of numbers broadcasted are coded as well giving the coordinates of pieces of a large machine called the Vacuum.
In the video game Call of Duty: Black Ops, the Campaign storyline features numbers stations as part of the plot.

The History of Amateur Radio

The american amateur Edmund B. Durham, 3VM, in 1914. This skilled OM who built two receivers, emitted in CW with 30 W using a 12 m high, 22.5 m long "T" antenna tuned on 180 meters. Document Spark Museum.

A long story (I)

Like any scientific story, I can not relate the venture of amateur radio without considering the socioeconomic context that saw its emergence. You will thus find on the next pages not only the story of amateur radio but also the one of the other discoveries and inventions that lead in a way or another to the development of radio communications.

To respect the History I have tried to use the vocabulary of the concerned time, using for example the megacycle (Mc) until 1960, when the Système International (SI) was adopted.

This study deals mainly with the amateur radio in the U.S.A., not only because it represents the largest ham community in the world with about 30% of licensees, but first of all because they have initiated many activities that have been later "exported" and used as it by the other nations.

However to please the international community of amateurs, I have tried to not forget the history of amateur radio in the other countries, in Canada, in the United Kingdom, in Belgium or in Japan to name some countries.

This story being quite long and representing a lot of information, I have tried to make it the less boring as possible and the most alife as possible. To help you to find quickly the information you need, here are the key dates and events in a few landmarks.

Here is how all this story began.

The time of discoveries

Come back in time. By 900 BC, in his "Odyssey", Homer dealed with "a golden chain of exquisite workmanship strung with amber beads that gleamed like the sun" that received Penelope as a gift. In the 1st century BC, in Imperial Rome, Pliny the Elder reported the discovery of a strange property of this matter called amber.

This yellow and translucent gemstone made of fossilized remains of tree resin was probably one of the first stone offering so-called curative properties against deafness and blindness, while once burnt its characteristic scent of pine had redolent of purification. Today the price of these amber drops can still be high, mainly when they content inclusions of bugs, flowers, etc, that lived on Earth during the Jurassic or Eocen time. The specimen displayed at left for example, extracted from my collection, is roughly 40 millions years ! This close-up is enlarged 2.5x.

But this stone had another property, still stranger. After have been rubbed with wool or by fur it is able of attracting thin objects like feathers, leaves and fibers. 600 years BC the famous Greek philosopher Thales of Miletus called this special property "elektron", from which is derived the latin word "electrocus" meaning "produce from amber by friction", and of course the modern word "electricity". In fact the amber is able of storing electricity and to produce discharges of static.

However, we had to wait the years 1800s and the works of Michael Faraday to discover the true relationship existing between electricity and magnetism. But his works were not associated to mathematic development. So, in 1873 the Scotsman James Clerk Maxwell whose picture is displayed at right, "redesigned" these concepts in mathematical form and invented the electromagnetic waves. Today, Maxwell's equations are always used to calculate characteristics of waves that they propagate in a tube receiver or a satellite antenna.

Maxwell created the fundamental concept of "field", giving up the one of electric fluids in ether. "The field told he, creates a canvas across all the sky". This property allows Maxwell to predict the existence of (electromagnetic) waves. Outside the field the force has no effect. This is for this reason that outside the electromagnetic field of a broadcasting station, we cannot hear at all its emissions.

The Conet Project

From Wikipedia, the free encyclopedia

Jump to: navigation, search

The Conet Project: Recordings of Shortwave Numbers Stations is a four-CD set of recordings of numbers stations, mysterious shortwave radio stations of uncertain origin believed to be operated by government agencies to communicate with spies "in the field". The collection was released by England's Irdial-Discs record label in 1997, based on the work of numbers station enthusiast Akin Fernandez.^[1]
The Conet Project has since become somewhat of a cult sensation and counts many musicians and filmmakers among its fans, including Wilco frontman Jeff Tweedy, Melvins collaborator David Scott Stone, Boards of Canada, The Besnard Lakes, Devendra Banhart, former Faith No More vocalist Mike Patton, and director Cameron Crowe. Samples from the collection have been used in numerous films and albums, including Crowe's film Vanilla Sky, Porcupine Tree's Stupid Dream album, We Were Promised Jetpacks' These Four Walls album, and Wilco's Yankee Hotel Foxtrot album, the last of which was an issue of legal dispute; Jeff Tweedy did not seek permission to use the Conet sample and Irdial sued for copyright infringement. The incident sparked debate about who exactly owns copyright concerning recordings of numbers station transmissions, but Tweedy ultimately decided to avoid taking the matter to court, agreeing to pay Irdial royalties and reimburse its legal fees.^[2] The Besnard Lakes have also used recordings from numbers stations throughout their album, The Besnard Lakes Are the Dark Horse and frontman Jace Lasek is said to be a fan of The Conet Project.
In keeping with its 'Free Music Philosophy',^[3] the Irdial-Discs label has made the entire collection available for download in MP3 form (along with a PDF version of the included booklet) on its website completely free of charge and encourages fans to freely distribute it on file sharing networks.
The project's name comes from a mishearing of the Czech word konec, or "end," which marks the end of transmissions on the Czech numbers station.
