Annual Report of the Commissioner of Navigation. On June 24, 1910, "An Act to require apparatus and operators for radio communication on certain ocean steamers" was passed by the U. S. Congress, to become effective July 1, 1911. Although it did not require station licences, the act did require that larger ocean-going vessels -- of all nationalities -- which visited U. S. ports have efficient radio equipment operated by certified operators. As part of its enforcement of the new act, the Bureau of Navigation included an appendix in its 1910 through 1912 annual reports containing detailed radio information about the vessels covered by the act. |

Radio Stations of the United States. The passage of the "Act to Regulate Radio Communication" meant that, effective December 13, 1912, U. S. ship and land radio stations had to have licences to order to operate transmitters. The Department of Commerce began issuing an annual list of licenced U. S. stations, which it divided into the following categories: Commercial [Ship/Public Service/Limited Commercial licences], Government, Amateur [General Amateur/Restricted Amateur licences], and Special Land [Experimental/Technical & Training School/Special Amateur licences]. |
