1912 __ International Radiotelegraphic Convention in London
Comment : The U.S. Congress finally passed a comprehensive Act to Regulate Radio Communication, which was signed by President Taft on August 13, 1912, and went into effect December 13, 1912. Officially this new law implemented provisions of the 1906 Berlin Convention. However, a new International Radiotelegraphic Convention had been signed in London on July 5, 1912, to become effective July 1, 1913, and the new U.S. law included many provisions which actually reflected standards of the soon-to-be ratified London Convention, most importantly the requirement that most radio transmitters had to be licenced, plus the provision that radio operators now had to quality for operator's licences, not just certification. The 1912 London International Radiotelegraphic Convention established international callsigns, replacing the three letter callsigns prevalent then. Major world powers were given single prefixes such as N/K/W (United States) A (Germany), F (France), B (Great Britain). British colonies were given the call signs starting with "V.

Original excerpt : « GENERAL RESTRICTIONS ON PRIVATE STATIONS.Fifteenth. No private or commercial station not engaged in the transaction of bona fide commercial business by radio communication or in experimentation in connection with the development and manufacture of radio apparatus for commercial purposes shall use a transmitting wave length exceeding two hundred meters, or a transformer input exceeding one kilowatt, except by special authority of the Secretary of Commerce contained in the license of that station: Provided, That the owner or operator of a station of the character mentioned in this regulation shall not be liable for a violation of the requirements of the third or fourth regulations to the penalties of one hundred dollars or twenty-five dollars, respectively, provided in this section unless the person maintaining or operating such station shall have been notified in writing that the said transmitter has been found, upon tests conducted by the Government, to be so adjusted as to violate the said third and fourth regulations, and opportunity has been given to said owner or operator to adjust said transmitter in conformity with said regulations. SPECIAL RESTRICTIONS IN THE VICINITIES OF GOVERNMENT STATIONS.Sixteenth. No station of the character mentioned in regulation fifteenth situated within five nautical miles of a naval or military station shall use a transmitting wave length exceeding two hundred meters or a transformer input exceeding one-half kilowatt.59. CLASS 3.--Experiment stations.--The Secretary of Commerce is authorized by section 4 of the act to grant special temporary licenses "to stations actually engaged in conducting experiments for the development of the science of radio communication, or the apparatus pertaining thereto, to carry on special tests, using any amount of power or any wave lengths, at such hours and under such conditions as will insure the least interference with the sending or receipt of commercial or Government radiograms, of distress signals and radiograms, or with the work of other stations." Applicants for such licenses should state any technical result they have already produced, their technical attainments, etc. The fact that an applicant desires to experiment with his equipment does not justify or require a license of this class. Most experiments can be made within the limitations of general and restricted amateur station licenses or by use of an artificial antenna to prevent radiation.65. CLASS 6.--General amateur stations are restricted to a transmitting wave length not exceeding 200 meters and a transformer input not exceeding 1 kilowatt. (Sec. 4, fifteenth regulation, act of Aug. 13, 1912.).66. CLASS 7.--Restricted amateur stations, within 5 nautical miles of a naval or military station, are restricted to a wave length not exceeding 200 meters and to a transformer input not exceeding one-half kilowatt. (Sec. 4, sixteenth regulation, act of Aug. 13, 1912.).67. Amateur first or second grade operators or higher are required for general and restricted amateur stations.68. The license does not specify the number of operators required, but provides that the station shall at all times while in operation be under the care of an operator licensed for that purpose. The grade and number of operators as required by law are determined by the service of the station.69. Special stations for exceptional distances are land stations designed to carry on transoceanic radio communication as between the United States and European countries, or between the Pacific coast and Hawaii, or from the United States over similar long distances at sea to another land station, or (inland) to carry on radio communication overland over exceptional distances. These stations will all come under one of the classifications named above, and the license will indicate the stations for which communication is authorized and indicate the range.89. The owner of an amateur station may operate his station in accordance with the laws if his application for a license has been properly filed but has not been acted upon. An application for an operator's license must also have been filed and every effort made to obtain the license before the station may be operated.121. Amateurs before applying for licenses should read and understand the essential parts of the International Radiotelegraphic Convention in force and sections 3, 4, 5, and 7 of the act of August 13, 1912. The Department recognizes that radio communication offers a wholesome form of instructive recreation for amateurs. At the same time its use for this purpose must observe strictly the rights of others to the uninterrupted use of apparatus for important public and commercial purposes. The Department will not knowingly issue a license to an amateur who does not recognize and will not obey this principle. To this end the intelligent reading of the International Convention and the act of Congress is prescribed as the first step to be taken by amateurs. A copy of the radio laws and regulations may be procured for this purpose from the radio inspectors or from the Commissioner of Navigation, Department of Commerce, Washington, D. C., but they are not for public distribution. Additional copies may be purchased from the Superintendent of Documents, Government Printing Office, Washington, D. C., at a nominal price.122. Amateur first grade.--The applicant must have a sufficient knowledge of the adjustment and operation of the apparatus which he wishes to operate and of the regulations of the International Convention and acts of Congress in so far as they relate to interference with other radio communication and impose certain duties on all grades of operators. The applicant must be able to transmit and receive in Continental Morse at a speed sufficient to enable him to recognize distress calls or the official "keep-out" signals. A speed of at least five words per minute (five letters to the word) must be attained. » (RADIO COMMUNICATION LAWS OF THE UNITED STATES AND THE INTERNATIONAL RADIOTELEGRAPHIC CONVENTION, EDITION JULY 27, 1914,DEPARTMENT OF COMMERCE UNITED STATES OF AMERICA, WASHINGTON GOVERNMENT PRINTING OFFICE, 1914 Thomas H.
