28–31 August 2009 and also within a few days of the 50th anniversary of the ship's first voyage. Satellite and Internet broadcasting Using land-based studios leased in Kent in the late 1990s, the station began broadcasting via satellites Astra 19.2°E and Eutelsat 28A, covering western Europe. These analogue transmissions ended and a full digital service from Astra 28.2°E started in February 2003. In 2002, Caroline began on WorldSpace satellite radio, continuing until Worldspace went bankrupt and re-organised its operations in 2008. On 12 June 2006, the station bought an EPG slot on Sky channel 0199. This ended on 1 July 2011 after a failure to renegotiate costs with Sky and deciding not to pursue a Freesat EPG slot. Surveys in 2008 and 2010 showed a small percentage listened via Sky, and that satellite listening had dropped by 9% since 2008, while online listening had increased by around 40%. Radio Caroline continued on satellite but required manual tuning. During 2013, a survey showed a continued move from satellite reception and growth in internet listening. Following negotiations with the service provider, satellite transmissions ended at midnight on 30 September 2013. Programmes were still heard on satellite until the provider replaced the signal with a 1 kHz tone on the morning of 1 October 2013. Internet streaming of Radio Caroline programmes continued. The Radio Caroline "album" station has been streamed on the internet for many years, accessible via the station's website, with more streams on various devices. Dedicated apps for listening via Apple IOS and Android devices are also available. In 2011 Radio Caroline joined Radioplayer UK, an internet service formed by the BBC, Global Radio and the Guardian Media Group that supplies a live feed of UK radio stations to across the world. On 4 May 2015, Radio Caroline started a 24-hour "Flashback" webstream carrying "oldies" music and jingles. Via Manx Radio Since September 2015, Radio Caroline has been broadcasting 'live' for one weekend each month as "Radio Caroline North" (with original DJs and a mixed 1960s, 1970s and 1980s music content and jingles) from its former home the MV Ross Revenge on the Blackwater Estuary in Essex, via Manx Radio's 1368 kHz 20 kW transmitter on the Isle of Man.
