"The Lincolnshire Poacher" was the nickname of a mysterious, powerful shortwave numbers station that used two bars from the English folk song "The Lincolnshire Poacher" as an interval signal. The radio station was believed to be operated by the British Secret Intelligence Service and emanated from the island of Cyprus.[1] Amateur direction finding had linked it with the Royal Air Force base at Akrotiri, Cyprus, where several curtain antennas had been identified as being its transmitter.[2] It consisted of an electronically synthesised English-accented female voice reading groups of five numbers: e.g. '0-2-5-8-8'. The final number in each group was spoken with a lifted voice. It is likely that the station was used to communicate to undercover agents (spies) operating in other countries, to be decoded using a one-time pad.[3]
An Asian numbers station of identical format is believed to be broadcast from Australia, and nicknamed "Cherry Ripe". It uses several bars from the English folk song of the same name as its interval signal.[3][4] As of July 2008 the Lincolnshire Poacher seems to be inactive, although Cherry Ripe continued to be online until December 2009.[5]

History [edit]
The precise date that the Lincolnshire Poacher began broadcasting is unknown; however, it is estimated that the broadcasts started around the early to mid-1970s.[6] While numbers stations have existed since World War I (making them some of the earliest radio transmissions) numbers stations such as Lincolnshire Poacher began appearing during the Cold War, when nations such as the Soviet Union and the United Kingdom needed to send messages discreetly to their operatives in other countries.[7] However, after the Cold War, the amount of numbers stations had greatly decreased.[7] The Lincolnshire Poacher remained operating after the end of the Cold War, though, and continued to be broadcast throughout the 1980s and 1990s.[3]
In July 2008, the Lincolnshire Poacher stopped broadcasting. The last recorded transmission of the station was on June 29, 2008.[6] It is believed that the station's sister station, Cherry Ripe, began to send broadcasts that used to be intended to be sent over the Lincolnshire Poacher station.[6] This is believed to be true because the "Cherry Ripe" station uses a very similar call signal as the Lincolnshire Poacher did, and broadcasts its messages in 200 sets of five-number IDs.[6]
Location [edit]
Although the usage of numbers stations has not been confirmed by any world government, amateur enthusiasts have traced the location of the Lincolnshire Poacher's signal transmission to RAF Akrotiri, a Royal Air Force base located on the Mediterranean island of Cyprus. The station is believed to be operated by the British Secret Intelligence Service (MI6) and maintained by the Royal Air Force members that occupy the base in Cyprus.[6]
Broadcast schedule [edit]
The Lincolnshire Poacher was broadcast several times throughout the day, and was transmitted seven days a week, at various times and on various shortwave frequencies. This schedule was accurate as of January 2006, which is the most recent update to the broadcast schedule. All times are Coordinated Universal Time (UTC), and all radio frequencies in Megahertz (MHz).[3]
