1906 __ Berlin International Wireless Telegraph Convention: November 3, 1906
Comment : In 1903, Germany sponsored a "preliminary conference concerning wireless telegraphy", held in Berlin, which reviewed some of the outstanding international issues related to the developing technology. Although the conference found some areas of agreement, there were still unresolved disputes, especially about intercommunication between stations owned by different companies. The Conference's Final Protocol outlined issues which the governments of the participating countries were asked to review, pending a proposed international convention, which convened in 1906. A second international radio conference was held in Berlin, Germany in 1906, to deal with issues left over from the 1903 Conference. The result was a comprehensive agreement, the International Wireless Telegraph Convention (Convention Radiotélégraphique Internationale), which was adopted on November 3, 1906, and became effective July 1, 1908. International Radio Telegraph Convention concluded between Germany, the United States of America, Argentina, Austria, Hungary, Belgium, Brazil, Bulgaria, Chile, Denmark, Spain, France, Great Britain, Greece, Italy, Japan, Mexico, Monaco, Norway, the Netherlands, Persia, Portugal, Roumania, Russia, Sweden, Turkey, and Uruguay.

Original excerpt : « [...] Nevertheless the radio apparatus and devices shall be of a kind to permit transmission by musical note for public correspondence." This addition has for its object the introduction of the use of systems having a musical note for public correspondence with a view to preventing, if possible, the detrimental effects due to atmospheric discharges. In this way radio correspondence can be carried on more successfully. "3. The musical note which stations on shipboard shall use for the transmission of public radio correspondence shall lie between (indicate a high musical note or the number of simple vibrations which form it) and (indicate another higher musical note or its number of vibrations)."In connection with the proposition referring to Article I it seems necessary to fix and indicate the musical notes which stations shall use. This is for the purpose of regulating the use of transmission by musical note which facilitates communications carried on simultaneously.
