The contra.cting Governments recognize the right of two con- tracting Governments to organize radio communications, between themselves, provided only that they conform to all provisions of the present Convention and the Regulations annexed thereto. ARTICLE 3 Intercommunication §1. (1) So far as internatioual communications between fixed sta- tions are concerned, each contracting Government reserves entire freedom with relation to the organization of the service and the determination of the correspondence to be exchanged by the stations carrying on these communications. . (2) When, however, these fixed stations carry on an interna.tional service of public correspondence, either from country to country or with stations in the mobile service, they must conform, respectively, for each of these two classes of communications, to the provisions of the pre:::ent Convention and of the Regulations annexed thereto. §2. With regard to communications between stations participating in the mobile service, stations carrying on such communications must, within the limits of their normal operations, exchange radiotelegrams reciprocally without regard to the radio system adopted by them. §3. In order not to impede scientific progress, however, the provi- sions of the preceding paragraph shall not prevent the eventual use of a radio system incapable of communicating with other systems, provided that this incapacity be due to the specific nature of that system and it be not the result of devices adopted solely for the purpose of preventing intercommunication. ARTICLE 4 Limited service Notwithstanding the provisions of Article 3, a radio communica- tion station may be assigned to a limited international service of public correspondence determined by the purpose of the correspondence or by other circumstances independent of the system employed. ARTICLE 5 Secrecy oj correspondence.
