 54STAT.] MULTILATERAL-TELECOMMUNICATIONAPR. 8, 1938 [1871 (b) Frequencies chosen in the portion of the band reserved to mobile services from 6,600 to 6,675 kc (45.45 to 44.94 m), in harmonic relation with the preceding bands, may also be used. [188] (c) The provisions of paragraph (2) (a) [No. 186] shall not apply to the portion of the shared band between 4,115 and 4,165 kc (72.90 and 72.03 m) which may be used by any ship station carrying on a commercial service. [189] (3) In selecting frequencies for new fixed and coast stations, the administrations shall avoid using the frequencies in the bands specified in paragraphs (1) (a), (2) (a), (2) (b), and (2) (c) [Nos. 181, 186, 187, and 188]. [190] §22. (1) It is recognized that the frequencies between 5,000 mnLonianc eom and 30,000 kc (60 and 10 m) are capable of propagation over great distances. [191] (2) The administrations shall make every possible effort to reserve the frequencies of this band for long-distance communications, in view of the fact that their use for short- or medium-distance com- munications is likely to interfere with long-distance communications. [192] (3) It is recommended that only transmitters having a power equal to at least 5 kw be used for long-distance broadcasting in this frequency band. [193] §23. In Europe, Africa, and Asia, low-power directional radio- beacons the range of which does not exceed about 50 km may use any frequency in the band 1,560 to 3,500 kc (192.3 to 85.71 m) except the guard band of 1,630 to 1,670 kc (184.0 to 179.6 m), subject to agreements with the countries whose services are likely to suffer interference. ARTICLE 8 Amateur Stations and Private Experimental Stations [194] §1. The exchange of communications between amateur sta- Exchange prowl- tions and between private experimental stations of different countries shall be forbidden if the administration of one of the interested countries has given notice of its opposition to this exchange. [1951 §2. (1) When this exchange is permitted, the communications must be carried on in plain language and be limited to messages re- lating to experiments and to remarks of a private nature for which, by reason of their lack of importance, the use of the telegraph service could not enter into consideration. It shall be strictly forbidden for owners of amateur stations to transmit international communications emanating from third persons. [196] (2) The foregoing provisions may be modified by special arrangements between the interested countries. [197] §3. In amateur stations or in private experimental stations, authorized to conduct transmissions, any person operating the ap- paratus on his own account or for third persons must have proved that he is able to transmit texts in Morse code signals and to read, 1473
