gal and the Portuguese Colonies, Roumania, Russia and the Russian Possessions and Protectorates, the Republic of San Marino, Siam, Sweden, Turkey, and Uruguay.
The undersigned, plenipotentiaries of the Governments of the countries enumerated above, having met in conference at London, have agreed on the following Convention, subject to ratification:
Article 1
The High Contracting Parties bind themselves to apply the provisions of the present Convention to all radio stations (both coastal stations and stations on shipboard) which are established or worked by the Contracting Parties and open to public service between the coast and vessels at sea.
They further bind themselves to make the observance of these provisions obligatory upon private enterprises authorized either to establish or work coastal stations for radiotelegraphy open to public service between the coast and vessels at sea, or to establish or work radio stations, whether open to general public service or not, on board of vessels flying their flag.
Article 2
By "coastal stations" is to be understood every radio station established on shore or on board a permanently moored vessel used for the exchange of correspondence with ships at sea.
Every radio station established on board any vessel not permanently moored is called a "station on shipboard."
Article 3
The coastal stations and the stations on shipboard shall be bound to exchange radiograms without distinction of the radio system adopted by such stations.
Every station on shipboard shall be bound to exchange radiograms with every other station on shipboard without distinction of the radio system adopted by such stations.
However, in order not to impede scientific progress, the provisions of the present Article shall not prevent the eventual employment of a radio system incapable of communicating with other systems, provided that such incapacity shall be due to the specific nature of such system and that it shall not be the result of devices adopted for the sole purpose of preventing intercommunication.
Article 4
Notwithstanding the provisions of Article 3, a station may be reserved for a limited public service determined by the object of the correspondence or by other circumstances independent of the system employed.
