ALLOCATION OF FREQUENCY BANDS BETWEEN 10 AND 200,000 кc (30,000 AND 1.5 M)-Continued [103] 10 On the entire territory of the U. S. S. R., the frequency bands from 380 to 395 kc (789 to 759 m) and from 515 to 550 kc (583 to 545 m) shall be used by the maritime and aeronautical mobile services, on condition that there will be no interference therefrom with the authorized services of other countries. [104] The band of 395-415 kc (759-723 m) shall be used only for communications between aircraft and aeronautical stations and by radiobeacons. ALLOCATION OF FREQUENCY BANDS BETWEEN 10 AND 200,000 κс (30,000 AND 1.5 M)-Continued Broadcast- [105] The European administrations shall be authorized to arrange among themselves to place in the band of 415-460 kc (723-652 m) broadcasting stations which, by reason of their geographical position and their limited power, will not interfere with the maritime mobile services. [106] The wave of 500 kc (600 m) shall be the international calling- and distress-wave. The use of this wave is defined in articles 19, 22, and 30 [21, 24, and 3271. [107] 14 The European administrations shall be authorized to arrange among themselves to maintain in the band 515-550 kc (583-545 m) the existing broadcasting stations which, by reason of their geographical position, will interfere neither with the mobile services in the band of 485-515 kc (619-583 m) nor with the services not open to public correspondence in the band of 515-550 kc (583-545 m). [108] Moreover, the services not open to public correspondence will be organized in such a manner as not to interfere with the reception of the broadcasting stations so chosen, within the limits of the national territories of these stations. [109] 18 The mobile services may use the band of 550 to 1,300 kc (545 to 230.8 m), on the condition that they will not interfere with the services of a country which uses that same band exclusively for broadcasting. [110] 16 The use of the frequency of 1,364 kc (219.9 m) in type-B waves shall be authorized in Japan, for small ships of which the power is below 300 watts, and on condition that no interference will result there. from to the services of other countries. However, in the region of North America, only type-A1 waves shall be authorized between 18:00 and 23:00 o'clock, local time. [111] 17 It is necessary for the frequencies of the carrier waves of broadcasting stations to keep a separation of 5 kc at least, from the upper limit of the allocated band. [113] 19As a general rule, this frequency band shall be reserved for the telephone service with low-power ship stations. The countries whose ships do not use this type of communication will avoid the use of telegraphy in this band in regions adjacent to those where this telephone service is operated. ALLOCATION OF FREQUENCY BANDS BETWEEN 10 AND 200,000 Kс (30,000 AND 1.5 M)-Continued [112] 18 The frequency of 1,650 kc (181.8 m) shall be both a calling-wave and the distress-wave for the mobile service of radiotelephony with low-power ship stations. The use of this wave shall be regulated by the provisions of article 31. [114] 20 No traffic can be carried on in the band of 1,630-1,670 kc (184.0-179.6 m).. [115] Within Europe, the frequency bands of 1,560–1,630 kc and of 1,670-1,715 kc (192.3-184.0 and 179.6174.9 m) may be used by the short-distance fixed services, provided that they will not interfere with the mobile services. [116] Note.-A European conference, which shall take place before the going into effect of these Regulations, may decide, as an exception, to annex to its protocol certain special derogations upon which it may decide in the regional bands and which it may deem necessary to show therein. Such derogations will be added to those provided for in the notes relating to the preceding table. [117] Over the entire territory of the U.S.S.R. the band from 2,000 to 2,050 kc (150 to 146.3 m) shall be used exclusively by the aeronautical services, provided that no interference occurs to the authorized services of other countries. ALLOCATION OF FREQUENCY BANDS BETWEEN 10 AND 200,000 кc (30,000 AND 1.5 M)-Continued General allocation 2,050-2,070 (146.3-144.9) ing (144.9-128.8) (112.8-106.8) ex 2,300-2,500 2,500-3,300 [118] 23 Over the entire territory of the U.S.S.R. allocations of the bands of 2,330 to 2,360 kc (128.8 to 127.1 m), 2,635 to 2.660 kc (113.9 to 112.8 m), 3,065 to 3,095 kc (97.88 to 96.93 m), 3,635 to 3,685 kc (82.53 to 81.41 m) and 4,480 to 4,530 kc (66.96 to 66.23 m) shall be made in accordance with the last column of the table (Other regions).
