Before 1 April 2007, the signal was transmitted from Rugby, Warwickshire 52°21′33″N 01°11′21″W / 52.35917°N 1.18917°W / 52.35917; -1.18917
Before 2008, transmitter located at 55°44′14″N 38°09′04″E / 55.73722°N 38.15111°E / 55.73722; 38.15111
^[16] says that the transmitter is located in Observatorio Naval Buenos Aires at Avenida España 2099, Buenos Aires; on Google Street View, some antenna structures can be seen both on and near the building, however, it's unclear where exactly the specific antenna is located. The coordinates here point to the building itself. 34°37′19″S 58°21′18″W / 34.62194°S 58.35500°W / -34.62194; -58.35500 (LOL)
