Radioreglement 1979
(authentiek: en)
Preamble
0.1 These Regulations are founded on the following principles:
0.2 Members 2)[1] shall endeavour to limit the number of frequencies and the spectrum used to the minimum essential to provide in a satisfactory manner the necessary services. To that end, they shall endeavour to apply the latest technical advances as soon as possible (No. 195 of the Constitution of the International Telecommunication Union (Geneva, 1992)).
0.3 In using frequency bands for radio services, Members shall bear in mind that radio frequencies and the geostationary-satellite orbit are limited natural resources and that they must be used rationally, efficiently and economically, in conformity with the provisions of these Regulations, so that countries or groups of countries may have equitable access to both, taking into account the special needs of the developing countries and the geographical situation of particular countries (No. 196 of the Constitution).
0.4 All stations, whatever their purpose, must be established and operated in such a manner as not to cause harmful interference to the radio services or communications of other Members or of recognized operating agencies, or of other duly authorized operating agencies which carry on a radio service, and which operate in accordance with the provisions of these Regulations (No. 197 of the Constitution).
0.5 With a view to fulfilling the purposes of the International Telecommunication Union set out in Article 1 of the Constitution, these Regulations have the following objectives:
0.6 to facilitate equitable access to and rational use of the natural resources of the radio-frequency spectrum and the geostationary-satellite orbit;
0.7 to ensure the availability and protection from harmful interference of the frequencies provided for distress and safety purposes;
0.8 to assist in the prevention and resolution of cases of harmful interference between the radio services of different administrations;
0.9 to facilitate the efficient and effective operation of all radiocommunication services;
0.10 to provide for and, where necessary, regulate new applications of radiocommunication technology.
0.11 The application of the provisions of these Regulations by the International Telecommunication Union does not imply the expression of any opinion whatsoever on the part of the Union concerning the sovereignty or the legal status of any country, territory or geographical area.

carrier power (PZ or pZ).
For different classes of emission, the relationships between peak envelope power, mean power and carrier power, under the conditions of normal operation and of no modulation, are contained in ITU-R Recommendations which may be used as a guide.
For use in formulae, the symbol p denotes power expressed in watts and the symbol P denotes power expressed in decibels relative to a reference level.

1.158 mean power (of a radio transmitter): The average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long compared with the lowest frequency encountered in the modulation taken under normal operating conditions.
1.159 carrier power (of a radio transmitter): The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle taken under the condition of no modulation.
1.160 gain of an antenna: The ratio, usually expressed in decibels, of the power required at the input of a loss-free reference antenna to the power supplied to the input of the given antenna to produce, in a given direction, the same field strength or the same power flux-density at the same distance. When not specified otherwise, the gain refers to the direction of maximum radiation. The gain may be considered for a specified polarization.
Depending on the choice of the reference antenna a distinction is made between:
a) absolute or isotropic gain (Gi), when the reference antenna is an isotropic antenna isolated in space;
b) gain relative to a half-wave dipole (Gd), when the reference antenna is a half-wave dipole isolated in space whose equatorial plane contains the given direction;
c) gain relative to a short vertical antenna (Gv), when the reference antenna is a linear conductor, much shorter than one quarter of the wavelength, normal to the surface of a perfectly conducting plane which contains the given direction.
1.161 equivalent isotropically radiated power (e.i.r.p.): The product of the power supplied to the antenna and the antenna gain in a given direction relative to an isotropic antenna (absolute or isotropic gain).
1.162 effective radiated power (e.r.p.) (in a given direction): The product of the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction.
1.163 effective monopole radiated power (e.m.r.p.) (in a given direction): The product of the power supplied to the antenna and its gain relative to a short vertical antenna in a given direction.

2.6 Whenever a specified time is used in international radiocommunication activities, UTC shall be applied, unless otherwise indicated, and it shall be presented as a four-digit group (0000-2359). The abbreviation UTC shall be used in all languages.

Section III. – Designation of emissions [Wordt voorlopig toegepast per 01-01-2013]

2.7 [Wordt voorlopig toegepast per 01-01-2013] Emissions shall be designated according to their necessary bandwidth and their classification in accordance with the method described in Appendix 1.
Article 3. Technical characteristics of stations [Wordt voorlopig toegepast per 01-01-2013]
3.1 [Wordt voorlopig toegepast per 01-01-2013] The choice and performance of equipment to be used in a station and any emissions therefrom shall satisfy the provisions of these Regulations.
3.2 Also, as far as is compatible with practical considerations, the choice of transmitting, receiving and measuring equipment shall be based on the most recent advances in the technique as indicated, inter alia, in ITU-R Recommendations.
3.3 Transmitting and receiving equipment intended to be used in a given part of the frequency spectrum should be designed to take into account the technical characteristics of transmitting and receiving equipment likely to be employed in neighbouring and other parts of the spectrum, provided that all technically and economically justifiable measures have been taken to reduce the level of unwanted emissions from the latter transmitting equipment and to reduce the susceptibility to interference of the latter receiving equipment.
3.4 To the maximum extent possible, equipment to be used in a station should apply signal processing methods which enable the most efficient use of the frequency spectrum in accordance with the relevant ITU-R Recommendations. These methods include, inter alia, certain bandwidth expansion techniques, and in particular, in amplitude-modulation systems, the use of the single-sideband technique.
3.5 Transmitting stations shall conform to the frequency tolerances specified in Appendix 2.
3.6 Transmitting stations shall conform to the maximum permitted power levels for unwanted emissions in the spurious domain specified in Appendix 3. (WRC-12)
3.7 Transmitting stations shall conform to the maximum permitted power levels for out-of-band emissions, or unwanted emissions in the out-of-band domain, specified for certain services and classes of emission in the present Regulations. In the absence of such specified maximum permitted power levels transmitting stations should, to the maximum extent possible, satisfy the requirements relating to the limitation of the out-of-band emissions, or unwanted emissions in the out-of-band domain, specified in the relevant ITU-R Recommendations. (WRC-12)
3.8 Moreover, every effort should be made to keep frequency tolerances and levels of unwanted emissions at the lowest values which the state of the technique and the nature of the service permit.
3.9 The bandwidths of emissions also shall be such as to ensure the most efficient utilization of the spectrum; in general this requires that bandwidths be kept at the lowest values which the state of the technique and the nature of the service permit. Appendix 1 is provided as a guide for the determination of the necessary bandwidth.
3.10 Where bandwidth-expansion techniques are used, the minimum spectral power density consistent with efficient spectrum utilization shall be employed.
3.11 Wherever necessary for efficient spectrum use, the receivers used by any service should comply as far as possible with the frequency tolerances of the transmitters of that service, due regard being paid to the Doppler effect where appropriate.
3.12 Receiving stations should use equipment with technical characteristics appropriate for the class of emission concerned; in particular, selectivity should be appropriate having regard to No. 3.9 on the bandwidths of emissions.
3.13 The performance characteristics of receivers should be adequate to ensure that they do not suffer from interference due to transmitters situated at a reasonable distance and which operate in accordance with these Regulations.
3.14 To ensure compliance with these Regulations, administrations shall arrange for frequent checks to be made of the emissions of stations under their jurisdiction. For this purpose, they shall use the means indicated in Article 16, if required. The technique of measurements and the intervals of measurements to be employed shall be, as far as is practicable, in accordance with the most recent ITU-R Recommendations.
3.15 The use of damped wave emissions is forbidden in all stations.
Article 4. Assignment and use of frequencies [Wordt voorlopig toegepast per 01-01-2013]
4.1 [Wordt voorlopig toegepast per 01-01-2013] Member States shall endeavour to limit the number of frequencies and the spectrum used to the minimum essential to provide in a satisfactory manner the necessary services. To that end they shall endeavour to apply the latest technical advances as soon as possible (CS 195).
4.2 Member States undertake that in assigning frequencies to stations which are capable of causing harmful interference to the services rendered by the stations of another country, such assignments are to be made in accordance with the Table of Frequency Allocations and other provisions of these Regulations.
4.3 Any new assignment or any change of frequency or other basic characteristic of an existing assignment (see Appendix 4) shall be made in such a way as to avoid causing harmful interference to services rendered by stations using frequencies assigned in accordance with the Table of Frequency Allocations in this Chapter and the other provisions of these Regulations, the characteristics of which assignments are recorded in the Master International Frequency Register.
4.4 Administrations of the Member States shall not assign to a station any frequency in derogation of either the Table of Frequency Allocations in this Chapter or the other provisions of these Regulations, except on the express condition that such a station, when using such a frequency assignment, shall not cause harmful interference to, and shall not claim protection from harmful interference caused by, a station operating in accordance with the provisions of the Constitution, the Convention and these Regulations.
4.5 The frequency assigned to a station of a given service shall be separated from the limits of the band allocated to this service in such a way that, taking account of the frequency band assigned to a station, no harmful interference is caused to services to which frequency bands immediately adjoining are allocated.
4.6 For the purpose of resolving cases of harmful interference, the radio astronomy service shall be treated as a radiocommunication service. However, protection from services in other bands shall be afforded the radio astronomy service only to the extent that such services are afforded protection from each other.
4.7 For the purpose of resolving cases of harmful interference, the space research (passive) service and the earth exploration-satellite (passive) service shall be afforded protection from different services in other bands only to the extent that these different services are protected from each other.
4.8 Where, in adjacent Regions or sub-Regions, a band of frequencies is allocated to different services of the same category (see Sections I and II of Article 5), the basic principle is the equality of right to operate. Accordingly, the stations of each service in one Region or sub-Region must operate so as not to cause harmful interference to any service of the same or higher category in the other Regions or sub-Regions. (WRC-03)
4.9 No provision of these Regulations prevents the use by a station in distress, or by a station providing assistance to it, of any means of radiocommunication at its disposal to attract attention, make known the condition and location of the station in distress, and obtain or provide assistance.
4.10 Member States recognize that the safety aspects of radionavigation and other safety services require special measures to ensure their freedom from harmful interference; it is necessary therefore to take this factor into account in the assignment and use of frequencies.
4.11 Member States recognize that among frequencies which have long-distance propagation characteristics, those in the bands between 5 MHz and 30 MHz are particularly useful for long-distance communications; they agree to make every possible effort to reserve these bands for such communications. Whenever frequencies in these bands are used for short- or medium-distance communications, the minimum power necessary shall be employed.
4.12 To reduce requirements for frequencies in the bands between 5 MHz and 30 MHz and thus to prevent harmful interference to long-distance radiocommunications, administrations are encouraged to use, whenever practicable, any other possible means of communication.
4.13 When special circumstances make it indispensable to do so, an administration may, as an exception to the normal methods of working authorized by these Regulations, have recourse to the special methods of working enumerated below, on the sole condition that the characteristics of the stations still conform to those inserted in the Master International Frequency Register:
4.14 a) a station in the fixed service or an earth station in the fixed-satellite service may, under the conditions defined in Nos. 5.28 to 5.31, transmit to mobile stations on its normal frequencies;
4.15 b) a land station may communicate, under the conditions defined in Nos. 5.28 to 5.31, with fixed stations in the fixed service or earth stations in the fixed-satellite service or other land stations of the same category.
4.15A (SUP - WRC-12)
4.16 However, in circumstances involving the safety of life, or the safety of a ship or aircraft, a land station may communicate with fixed stations or land stations of another category.
4.17 Any administration may assign a frequency in a band allocated to the fixed service or allocated to the fixed-satellite service to a station authorized to transmit, unilaterally, from one specified fixed point to one or more specified fixed points provided that such transmissions are not intended to be received directly by the general public.
4.18 Any mobile station using an emission which satisfies the frequency tolerance applicable to the coast station with which it is communicating may transmit on the same frequency as the coast station on condition that the latter requests such transmission and that no harmful interference is caused to other stations.
4.19 In certain cases provided for in Articles 31 and 51, aircraft stations are authorized to use frequencies in the bands allocated to the maritime mobile service for the purpose of communicating with stations of that service (see No. 51.73). (WRC-07)
4.20 Aircraft earth stations are authorized to use frequencies in the bands allocated to the maritime mobile-satellite service for the purpose of communicating, via the stations of that service, with the public telegraph and telephone networks.
4.21 In exceptional cases, land mobile earth stations in the land mobile-satellite service may communicate with stations in the maritime mobile-satellite and aeronautical mobile-satellite services. Such operations shall comply with the relevant provisions of the Radio Regulations relating to those services and shall be subject to agreement among administrations concerned, taking due account of No. 4.10.
4.22 Any emission capable of causing harmful interference to distress, alarm, urgency or safety communications on the international distress and emergency frequencies established for these purposes by these Regulations is prohibited. Supplementary distress frequencies available on less than a worldwide basis should be afforded adequate protection.
4.23 Transmissions to or from high altitude platform stations shall be limited to bands specifically identified in Article 5. (WRC-12)

Section I. – Introduction [Wordt voorlopig toegepast per 01-01-2013]

12.1 [Wordt voorlopig toegepast per 01-01-2013] The use of the frequency bands allocated to high frequency broadcasting (HFBC) between 5 900 kHz and 26 100 kHz shall be based on the principles given below and shall be in conformity with seasonal planning based on a coordination procedure between administrations (referred in this Article as the Procedure) described in 12.2 to 12.45. An administration may authorize a broadcasting organization (referred to in this Article as a broadcaster), among others, to act on its behalf in this coordination.

Section II. – Principles [Wordt voorlopig toegepast per 01-01-2013]

12.2 [Wordt voorlopig toegepast per 01-01-2013] § 1 The Procedure shall be based on the principle of equal rights of all countries, large or small, to equitable access to these bands. Attempts shall also be made to achieve efficient use of these frequency bands, account being taken of the technical and economic constraints that may exist in certain cases. On the basis of the foregoing, the following principles shall be applied.
12.3 § 2 All broadcasting requirements, formulated by administrations, shall be taken into account and treated on an equitable basis, so as to guarantee the equality of rights referred to in No. 12.2, and to enable each administration to provide a satisfactory service.
12.4 § 3 The Procedure shall be based solely on the broadcasting requirements expected to become operational during the schedule period. It shall furthermore be flexible in order to take into account new broadcasting requirements and modifications to existing broadcasting requirements.
12.5 § 4 All broadcasting requirements, national 79)[77] and international, shall be treated on an equal basis, with due consideration of the differences between these two kinds of broadcasting requirements.
12.6 § 5 In the Procedure, an attempt shall be made to ensure, as far as practicable, continuity of use of a frequency or of a frequency band.
12.7 § 6 The Procedure shall be based on double-sideband or single-sideband emissions. Other modulation techniques recommended by ITU-R shall be permitted in place of double-sideband or single-sideband emissions, provided that the level of interference caused to existing emissions is not increased.
12.8 § 7 To promote efficient spectrum use, the number of frequencies used shall be the minimum necessary to provide a satisfactory quality of reception. Whenever practicable, only one frequency should be used.
12.9 § 8 The Procedure shall include a technical analysis, as specified in the Radio Regulations Board Rules of Procedure.
12.10 § 9 The Procedure should encourage administrations or broadcasters empowered to make changes to pursue a continual coordination process to resolve incompatibilities, at meetings (regional 80)[78] or worldwide, bilateral or multilateral) or by correspondence.
12.11 § 10 Regional coordination groups, which will facilitate bilateral and multilateral coordination among administrations and broadcasters in various regions of the world, shall identify themselves to the Bureau. Administrations and broadcasters shall be urged to participate in the relevant regional coordination groups. However, such participation would be on a voluntary basis.
12.12 § 11 When an administration, in particular the administration of a developing country, requests assistance in the application of the Procedure, the Bureau shall take appropriate action, including, if need be, coordination of the requirements submitted by the requesting administration.
12.13 § 12 The regional coordination groups should follow the coordination procedures prescribed in Section III. In the process of coordinating broadcasting requirements, an attempt shall be made to obtain agreement to the maximum number of submitted requirements with the quality level acceptable to administrations or broadcasters.
12.14 § 13 In order to ensure maximum success from the Procedure, administrations and broadcasters shall show the utmost goodwill and mutual cooperation, and give due consideration to all the relevant technical and operational factors involved.

Section III. – The Procedure [Wordt voorlopig toegepast per 01-01-2013]

12.15 [Wordt voorlopig toegepast per 01-01-2013] The application of the Procedure shall be facilitated and coordinated by the Bureau as defined elsewhere in this Article.
12.16 Twice yearly, administrations shall submit their projected seasonal broadcasting schedules in the relevant frequency bands to the Bureau. These schedules shall cover the following seasonal periods:
12.17 Schedule A: Last Sunday in March to last Sunday in October.
12.18 Schedule B: Last Sunday in October to last Sunday in March.
12.19 Implementation of these schedules shall start at 0100 UTC.
12.20 If an administration considers it necessary to take account of propagation changes during the schedule period, it is recommended, for reasons of spectrum efficiency, that such requirements should be implemented on the following dates:
12.21 first Sunday in May;
12.22 first Sunday in September.
12.23 Implementation of these changes shall start at 0100 UTC on these dates.
12.24 Other start and stop dates within a schedule period may be used to accommodate requirements that have different schedule periods, e.g. special events, clock changes on different dates not coincident with the schedule period, etc.
12.25 Administrations may include assignments in their schedules up to one year in advance of their use.
12.26 In those cases where an administration does not indicate its requirements for a new seasonal schedule, the Bureau shall use the assignments from the previous corresponding seasonal schedule for this administration for the new schedule period. A note in the schedule shall be used to identify such requirements. The Bureau shall follow this practice for two consecutive schedule periods.
12.27 Following the action taken in No. 12.26, the Bureau shall notify the administration concerned that the schedule will not include their broadcasting requirements unless the administration advises otherwise.
12.28 When an administration decides to cease its broadcasting service in the HF bands, it shall notify the Bureau of that decision.
12.29 The frequencies in the schedules should be those that will be used during the season concerned, and should be the minimum number required to provide satisfactory reception of the programmes in each of the areas and for each of the periods intended. In each schedule, to the maximum possible extent, the frequencies to be used in each reception area should remain unchanged from season to season.
12.30 Administrations are encouraged to coordinate their schedules with other administrations as far as possible prior to submission. An administration may, on behalf of a group of administrations, submit their coordinated schedules, the frequencies of which shall however have no priority for use over those submitted by other administrations.
12.31 The closing dates for receipt by the Bureau of the schedules relating to the two seasons referred to in No. 12.17 and 12.18 shall be established and published by the Bureau.
12.32 The schedules shall be submitted with the relevant data as specified in Appendix 4.
12.33 Upon receipt of the schedules, the Bureau shall, in accordance with the Rules of Procedure, validate the data where necessary, perform a compatibility analysis and prepare the tentative high frequency broadcasting schedules (the Tentative Schedules). These Schedules shall include all assignments where administrations gave no alternatives, the selections made by the Bureau from any alternatives given, and the frequencies selected by the Bureau in cases where the need for its assistance was indicated by their intentional omission from the individual schedules. (WRC-03)
12.34 The Tentative Schedules shall be published two months and one month before the start of each of the two schedule periods in Nos. 12.17 and 12.18. (WRC-03)
12.35 Administrations should examine the Tentative Schedule and should coordinate their frequency schedules to resolve or to minimize, as far as possible, any incompatibilities identified by the compatibility analysis, or by the monitoring results of similar assignments, or by a combination of both.
12.36 Coordination shall be achieved through bilateral or multilateral meetings of administrations or broadcasters or other means acceptable to the parties concerned.
12.37 Administrations, either jointly or separately, shall inform the Bureau, as quickly as possible, but no later than two weeks prior to the start of the schedule period, of any changes to their requirements resulting from the coordination process. The Bureau shall prepare a new consolidated high frequency broadcasting schedule (the Schedule), and shall perform a new compatibility analysis. The Bureau shall publish the Schedule and the results of the compatibility analysis at the start of the relevant broadcasting season.
12.38 Administrations shall notify the Bureau of changes to their schedules as quickly as possible and the Bureau shall update and make available the Schedule on a monthly basis. The Bureau shall perform new compatibility analyses and publish the updated Schedule and the results of these analyses at regular intervals during the season. (WRC-03)
12.39 To facilitate the coordination process, the Bureau shall also forward the schedules to the regional coordination groups.
12.40 Regional coordination groups should consider communicating with administrations and broadcasters through the use of any appropriate, mutually agreeable means, such as e-mail, news-groups, bulletin boards and other forms of electronic data transfer.
12.41 Each regional coordination group should consider appointing a steering committee to ensure smooth progress of the coordination process.
12.42 During and after the coordination process, the regional coordination groups shall exchange schedule data among themselves with a view to further enhancing the efficacy of the coordination process.
12.43 One month after the end of a season, the Bureau shall publish the final high frequency broadcasting schedule (the Final Schedule). If any changes have been notified to the Bureau since the previous consolidated Schedule, the Bureau shall also perform a compatibility analysis and publish it with the Final Schedule.
12.44 The Bureau should, as and when required, convene joint meetings of the representatives of all the regional coordination groups to develop strategies for further reduction of incompatibilities and to discuss related matters. The outcome of these meetings shall be circulated among the regional groups and administrations.
12.45 In a case of harmful interference involving the application of the provisions of Article 15, administrations are urged to exercise the utmost goodwill and mutual cooperation, taking into account all the relevant technical and operational factors of the case.

15.27 § 19 Full particulars relating to harmful interference shall, whenever possible, be given in the form indicated in Appendix 10.
15.28 § 20 Recognizing that transmissions on distress and safety frequencies and frequencies used for the safety and regularity of flight (see Article 31 and Appendix 27) require absolute international protection and that the elimination of harmful interference to such transmissions is imperative, administrations undertake to act immediately when their attention is drawn to any such harmful interference. (WRC-07)
15.29 § 21 In cases of harmful interference where rapid action is required, communications between administrations shall be transmitted by the quickest means available and, subject to prior authorization by the administrations concerned in such cases, information may be exchanged directly between specially designated stations of the international monitoring system.
15.30 § 22 When a case of such harmful interference is reported by a receiving station, it shall give to the transmitting station whose service is being interfered with all possible information which will assist in determining the source and characteristics of the interference.
15.31 § 23 If a case of harmful interference so justifies, the administration having jurisdiction over the receiving station experiencing the interference shall inform the administration having jurisdiction over the transmitting station whose service is being interfered with, giving all possible information.
15.32 § 24 If further observations and measurements are necessary to determine the source and characteristics of and to establish the responsibility for the harmful interference, the administration having jurisdiction over the transmitting station whose service is being interfered with may seek the cooperation of other administrations, particularly of the administration having jurisdiction over the receiving station experiencing the interference, or of other organizations.
15.33 § 25 When cases of harmful interference occur as a result of emissions from space stations, the administrations having jurisdiction over these interfering stations shall, upon request from the administration having jurisdiction over the station experiencing the interference, furnish current ephemeral data necessary to allow determination of the positions of the space stations when not otherwise known.
15.34 § 26 Having determined the source and characteristics of the harmful interference, the administration having jurisdiction over the transmitting station whose service is being interfered with shall inform the administration having jurisdiction over the interfering station, giving all useful information in order that this administration may take such steps as may be necessary to eliminate the interference.
15.35 § 27 On being informed that a station over which it has jurisdiction is believed to have been the cause of harmful interference, an administration shall, as soon as possible, acknowledge receipt of that information by the quickest means available. Such acknowledgement shall not constitute an acceptance of responsibility. (WRC-2000)
15.36 § 28 When a safety service suffers harmful interference the administration having jurisdiction over the receiving station experiencing the interference may also approach directly the administration having jurisdiction over the interfering station. The same procedure may also be followed in other cases with the prior approval of the administration having jurisdiction over the transmitting station whose service is being interfered with.
15.37 § 29 An administration receiving a communication to the effect that one of its stations is causing harmful interference to a safety service shall promptly investigate the matter and take any necessary remedial action and respond in a timely manner. (WRC-2000)
15.38 § 30 When the service rendered by an earth station suffers harmful interference, the administration having jurisdiction over the receiving station experiencing such interference may also approach directly the administration having jurisdiction over the interfering station.
15.39 § 31 If the harmful interference persists in spite of the action taken in accordance with the procedures outlined above, the administration having jurisdiction over the transmitting station whose service is being interfered with may address to the administration having jurisdiction over the interfering station a report of irregularity or infraction in accordance with the provisions of Section V.
15.40 § 32 If there is a specialized international organization for a particular service, reports of irregularities and of infractions relating to harmful interference caused or suffered by stations in this service may be addressed to such organization at the same time as to the administration concerned.
15.41 § 33 1) If it is considered necessary, and particularly if the steps taken in accordance with the procedures described above have not produced satisfactory results, the administration concerned shall forward details of the case to the Bureau for its information.
15.42 2) In such a case, the administration concerned may also request the Bureau to act in accordance with the provisions of Section I of Article 13; but it shall then supply the Bureau with the full facts of the case, including all the technical and operational details and copies of the correspondence.
15.43 § 34 1) In the case where an administration has difficulty in identifying a source of harmful interference in the HF bands and urgently wishes to seek the assistance of the Bureau, it shall promptly inform the Bureau.
15.44 2) On receipt of this information, the Bureau shall immediately request the cooperation of appropriate administrations or specially designated stations of the international monitoring system that may be able to help in identifying the source of harmful interference.
15.45 3) The Bureau shall consolidate all reports received in response to requests under No. 15.44 and, using such other information as it has available, shall promptly attempt to identify the source of harmful interference.
15.46 4) The Bureau shall thereafter forward its conclusions and recommendations to the administration reporting the case of harmful interference. These shall also be forwarded to the administration believed to be responsible for the source of harmful interference, together with a request for prompt action.

In accordance with No. 20.16, administrations shall notify the Radiocommunication Bureau immediately when assigning maritime mobile service identities. (WRC-12)
19.100 § 40 1) Maritime mobile service identities are formed of a series of nine digits which are transmitted over the radio path in order to uniquely identify ship stations, ship earth stations, coast stations, coast earth stations, and other non-shipborne stations operating in the maritime mobile service or the maritime mobile-satellite service, and group calls. (WRC-07)
19.101 2) These identities are formed in such a way that the identity or part thereof can be used by telephone and telex subscribers connected to the public telecommunications network principally to call ships automatically in the shore-to-ship direction. Access to public networks may also be achieved by means of free-form numbering plans, so long as the ship can be uniquely identified using the system’s registration database (see No. 19.31A) to obtain the ship station identity, call sign or ship name and nationality. (WRC-03)

Section VI. – Off-axis power limits on earth stations of a geostationary-satellite network in the fixed-satellite service 103)[106] 104)[107] [Wordt voorlopig toegepast per 01-01-2013]

22.26 [Wordt voorlopig toegepast per 01-01-2013] § 9 The level of equivalent isotropically radiated power (e.i.r.p.) emitted by an earth station of a geostationary-satellite network shall not exceed the following values for any off-axis angle ? which is 3° or more off the main-lobe axis of an earth station antenna:

7° < ? ? 9.2° 21 dB(W/40 kHz)  
9.2° < ? ? 48° 45 - 25 log ? dB(W/40 kHz)  
48° < ? ? 180° 3 dB(W/40 kHz) (WRC-2000)

22.27 For frequency-modulated television emissions with energy dispersal, the limits in No. 22.26 above may be exceeded by up to 3 dB, provided that the off-axis total e.i.r.p. of the transmitted frequency-modulated television carrier does not exceed the following values:
Off-axis angle Maximum e.i.r.p.

7° < ? ? 9.2° 35 dBW  
9.2° < ? ? 48° 59 - 25 log ? dBW  
48° < ? ? 180° 17 dBW (WRC-2000)

22.28 Frequency-modulated television carriers which operate without energy dispersal should be modulated at all times with programme material or appropriate test patterns. In this case, the off-axis total e.i.r.p. of the emitted frequency-modulated television carrier shall not exceed the following values:
Off-axis angle Maximum e.i.r.p.

12.75-13.25 GHz  
13.75-14 GHz  
14-14.5 GHz. (WRC-97)

22.30 The e.i.r.p. limits given in Nos. 22.26, 22.27, 22.28 and 22.32 do not apply to earth station antennas in service or ready to be in service 105)[108] prior to 2 June 2000, nor to earth stations associated with a satellite network in the fixed-satellite service for which complete coordination or notification information has been received before 2 June 2000. (WRC-2000)
22.31 Telecommand and ranging 106)[109] carriers transmitted to geostationary satellites in the fixed-satellite service in normal mode of operation (i.e. earth station transmitting telecommand and ranging carriers to a directional receiving antenna on the space station) may exceed the levels given in No. 22.26 by no more than 16 dB in the frequency bands 12.75-13.25 GHz and 13.75-14.5 GHz. In all other modes of operation, and in case of force majeure, telecommand and ranging carriers transmitted to geostationary satellites in the fixed-satellite service are exempted from the levels given in No. 22.26. (WRC-2000)
22.32 § 10 The level of equivalent isotropically radiated power (e.i.r.p.) density emitted by an earth station in a geostationary-satellite network in the 29.5-30 GHz frequency band shall not exceed the following values for any off-axis angle ? which is 3° or more off the main-lobe axis of an earth station antenna:

22.33 Not used. (WRC-2000)
22.34 Telecommand and ranging carriers transmitted to geostationary satellites in the fixed-satellite service in normal mode of operation (i.e. earth station transmitting telecommand and ranging carriers to a directional receiving antenna on the space station) may exceed the levels given in No. 22.32 by no more than 10 dB in the frequency band 29.5-30 GHz. In all other modes of operation, and in case of force majeure, telecommand and ranging carriers transmitted to geostationary satellites in the fixed-satellite service are exempted from the levels given in No. 22.32. (WRC-2000)
22.35 For geostationary-satellite systems in which the earth stations are expected to transmit simultaneously in the same 40 kHz band, e.g. for geostationary-satellite systems employing code-division multiple access, the maximum e.i.r.p. values given in No. 22.32 should be decreased by 10 log(N) dB, where N is the number of earth stations which are in the receive satellite beam of the satellite with which these earth stations are communicating and which are expected to transmit simultaneously on the same frequency. (WRC-2000)
22.36 Earth stations operating in the frequency band 29.5-30 GHz should be designed in such a manner that 90% of their peak off-axis e.i.r.p. density levels do not exceed the values given in No. 22.32. Further study is needed to determine the off-axis angular range over which these exceedences would be permitted, taking into account the interference level into adjacent satellites. The statistical processing of the off-axis e.i.r.p. density peaks should be carried out using the method given in the most recent version of Recommendation ITU-R S.732. (WRC-07)
22.37 The limits given in Nos. 22.26 to 22.28 and 22.32 apply under clear-sky conditions. During rain-fade conditions, the limits may be exceeded by earth stations when using uplink power control. (WRC-2000)
22.38 Earth stations in the fixed-satellite service operating in the 29.5-30 GHz band, which have lower elevation angles to the geostationary-satellite orbit, will require higher e.i.r.p. levels relative to the same terminals at higher elevation angles to achieve the same power flux-densities at the geostationary-satellite orbit, due to the combined effect of increased distance and atmospheric absorption. Earth stations with low elevation angles may exceed the levels given in No. 22.32 by the following amounts:
Elevation angle to geostationary-satellite orbit, ? Increase in e.i.r.p. density (dB)  
? ? 5° 2.5  
5° < ? ? 30° 0.1(25 ? ?) + 0.5 (WRC-2000)

22.39 The values in No. 22.32 applicable to the off-axis angle range from 48° to 180° are intended to account for spillover effects. (WRC-2000)

32.9 § 7 1) The transmission of a distress alert or a distress call indicates that a mobile unit 112)[115] or person 113)[116] is threatened by grave and imminent danger and requires immediate assistance. (WRC-07)
32.10 2) The distress alert shall provide 114)[117] the identification of the station in distress and its position.
32.10A § 7A 1) A distress alert is false if it was transmitted without any indication that a mobile unit or person was in distress and required immediate assistance (see No. 32.9). Administrations receiving a false distress alert shall report this infringement in accordance with Section V of Article 15, if that alert:
a) was transmitted intentionally;
b) was not cancelled in accordance with No. 32.53A and Resolution 349 (WRC-97) 115)[118] ;
c) could not be verified as a result of either the ship’s failure to keep watch on appropriate frequencies in accordance with Nos. 31.16 to 31.20, or its failure to respond to calls from an authorized rescue authority;
d) was repeated; or
e) was transmitted using a false identity.
Administrations receiving such a report shall take appropriate steps to ensure that the infringement does not recur. No action should normally be taken against any ship or mariner for reporting and cancelling a false distress alert. (WRC-07)

the distress signal “MAYDAY”;
the name of the vessel in distress;
the call sign or other identification;
the MMSI (if the initial alert has been sent by DSC);
the position, given as the latitude and longitude, or if the latitude and longitude are not known or if time is insufficient, in relation to a known geographical location;
the nature of the distress;
the kind of assistance required;
any other useful information. (WRC-12)
32.13E § 9C DSC procedures use a combination of automated functions and manual intervention to generate the appropriate distress call format in the most recent version of Recommendation ITU-R M.541. A distress alert sent by DSC consists of one or more distress alert attempts in which a message format is transmitted identifying the station in distress, giving its last recorded position and, if entered, the nature of the distress. In MF and HF bands, distress alert attempts may be sent as a single-frequency attempt or a multi-frequency attempt on up to six frequencies within one minute. In VHF bands, only single-frequency call attempts are used. The distress alert will repeat automatically at random intervals, a few minutes apart, until an acknowledgement sent by DSC is received.

Section III. – Distress traffic [Wordt voorlopig toegepast per 01-01-2013]

32.39 [Wordt voorlopig toegepast per 01-01-2013] A ? General and search and rescue coordinating communications
32.40 § 25 Distress traffic consists of all messages relating to the immediate assistance required by the ship in distress, including search and rescue communications and on-scene communications. The distress traffic shall as far as possible be on the frequencies contained in Article 31.
32.41 (SUP - WRC-07)
32.42 § 26 For distress traffic by radiotelephony, when establishing communications, calls shall be prefixed by the distress signal MAYDAY.
32.43 § 27 1) Error correction techniques in accordance with relevant ITU-R Recommendations shall be used for distress traffic by direct-printing telegraphy. All messages shall be preceded by at least one carriage return, a line feed signal, a letter shift signal and the distress signal MAYDAY.
32.44 2) Distress communications by direct-printing telegraphy should normally be established by the ship in distress and should be in the broadcast (forward error correction) mode. The ARQ mode may subsequently be used when it is advantageous to do so.
32.45 § 28 1) The rescue coordination centre responsible for controlling a search and rescue operation shall also coordinate the distress traffic relating to the incident or may appoint another station to do so. (WRC-07)
32.46 2) The rescue coordination centre coordinating distress traffic, the unit coordinating search and rescue operations 120)[123] or the coast station involved may impose silence on stations which interfere with that traffic. This instruction shall be addressed to all stations or to one station only, according to circumstances. In either case, the following shall be used:
32.47 a) in radiotelephony, the signal SEELONCE MAYDAY, pronounced as the French expression “silence, m’aider”;
32.48 b) in narrow-band direct-printing telegraphy normally using forward-error correcting mode, the signal SILENCE MAYDAY. However, the ARQ mode may be used when it is advantageous to do so.
32.49 § 29 Until they receive the message indicating that normal working may be resumed (see No. 32.51), all stations which are aware of the distress traffic, and which are not taking part in it, and which are not in distress, are forbidden to transmit on the frequencies in which the distress traffic is taking place.
32.50 § 30 A station of the mobile service which, while following distress traffic, is able to continue its normal service, may do so when the distress traffic is well established and on condition that it observes the provisions of No. 32.49 and that it does not interfere with distress traffic.
32.51 § 31 When distress traffic has ceased on frequencies which have been used for distress traffic, the station controlling the search and rescue operation shall initiate a message for transmission on these frequencies indicating that distress traffic has finished. (WRC-07)
32.52 § 32 1) In radiotelephony, the message referred to in No. 32.51 should consist of the following taking into account Nos. 32.6 and 32.7:
the distress signal “MAYDAY”;
the words “ALL STATIONS”, spoken three times;
the words “THIS IS”;
the name of the station sending that message, spoken three times;
the call sign or other identification of the station sending the message;
the time of handing in of the message;
the MMSI (if the initial alert has been sent by DSC), the name and the call sign of the mobile station which was in distress;
the words “SEELONCE FEENEE” pronounced as the French words “silence fini”. (WRC-12)

32.53B § 32A 1) A station transmitting an inadvertent distress alert or call shall cancel the transmission. (WRC-07)
32.53C 2) An inadvertent DSC alert shall be cancelled by DSC, if the DSC equipment is so capable. The cancellation should be in accordance with the most recent version of Recommendation ITU-R M.493. In all cases, cancellations shall also be transmitted by radiotelephone in accordance with 32.53E. (WRC-07)
32.53D 3) An inadvertent distress call shall be cancelled by radiotelephone in accordance with the procedure in 32.53E. (WRC-07)
32.53E 4) Inadvertent distress transmissions shall be cancelled orally on the associated distress and safety frequency in the same band on which the distress transmission was sent, using the following procedure, taking into account Nos. 32.6 and 32.7:
the words “ALL STATIONS”, spoken three times;
the words “THIS IS”;
the name of the vessel, spoken three times;
the call sign or other identification;
the MMSI (if the initial alert has been sent by DSC);
the words “PLEASE CANCEL MY DISTRESS ALERT OF” followed by the time in UTC.
Monitor the same band on which the inadvertent distress transmission was sent and respond to any communications concerning that distress transmission as appropriate. (WRC-12)
32.54 B ? On-scene communications
32.55 § 33 1) On-scene communications are those between the mobile unit in distress and assisting mobile units, and between the mobile units and the unit coordinating search and rescue operations 121)[124] .
32.56 2) Control of on-scene communications is the responsibility of the unit coordinating search and rescue operations9. Simplex communications shall be used so that all on-scene mobile stations may share relevant information concerning the distress incident. If direct-printing telegraphy is used, it shall be in the forward error-correcting mode.
32.57 § 34 1) The preferred frequencies in radiotelephony for on-scene communications are 156.8 MHz and 2 182 kHz. The frequency 2 174.5 kHz may also be used for ship-to-ship on-scene communications using narrow-band direct-printing telegraphy in the forward error correcting mode.
32.58 2) In addition to 156.8 MHz and 2 182 kHz, the frequencies 3 023 kHz, 4 125 kHz, 5 680 kHz, 123.1 MHz and 156.3 MHz may be used for ship-to-aircraft on-scene communications.
32.59 § 35 The selection or designation of on-scene frequencies is the responsibility of the unit coordinating search and rescue operations9. Normally, once an on-scene frequency is established, a continuous aural or teleprinter watch is maintained by all participating on-scene mobile units on the selected frequency.
32.60 C ? Locating and homing signals
32.61 § 36 1) Locating signals are radio transmissions intended to facilitate the finding of a mobile unit in distress or the location of survivors. These signals include those transmitted by searching units, and those transmitted by the mobile unit in distress, by survival craft, by float-free EPIRBs, by satellite EPIRBs and by search and rescue radar transponders to assist the searching units.
32.62 2) Homing signals are those locating signals which are transmitted by mobile units in distress, or by survival craft, for the purpose of providing searching units with a signal that can be used to determine the bearing to the transmitting stations.
32.63 3) Locating signals may be transmitted in the following frequency bands:
117.975-137 MHz;
156-174 MHz;
406-406.1 MHz; and
9 200-9 500 MHz. (WRC-07)

Section III. – Medical transports [Wordt voorlopig toegepast per 01-01-2013]

33.19 [Wordt voorlopig toegepast per 01-01-2013] § 10 The term “medical transports”, as defined in the 1949 Geneva Conventions and Additional Protocols, refers to any means of transportation by land, water or air, whether military or civilian, permanent or temporary, assigned exclusively to medical transportation and under the control of a competent authority of a party to a conflict or of neutral States and of other States not parties to an armed conflict, when these ships, craft and aircraft assist the wounded, the sick and the shipwrecked.
33.20 § 11 1) For the purpose of announcing and identifying medical transports which are protected under the above-mentioned Conventions, the procedure of Section II of this Article is used. The urgency call shall be followed by the addition of the single word MEDICAL in narrow-band direct-printing and by the addition of the single word MAY-DEE-CAL pronounced as in French “médical”, in radiotelephony. (WRC-07)
33.20A 2) When using digital selective calling techniques, the urgency announcement on the appropriate Digital Selective Calling distress and safety frequencies shall always be addressed to all stations on VHF and to a specified geographical area on MF and HF and shall indicate “Medical transport” in accordance with the most recent version of Recommendations ITU-R M.493 and ITU-R M.541. (WRC-07)
33.20B 3) Medical transports may use one or more of the distress and safety traffic frequencies specified in Section I of Article 31 for the purpose of self-identification and to establish communications. As soon as practicable, communications shall be transferred to an appropriate working frequency. (WRC-07)
33.21 § 12 The use of the signals described in Nos. 33.20 and 33.20A indicates that the message which follows concerns a protected medical transport. The message shall convey the following data: (WRC-07)
33.22 a) call sign or other recognized means of identification of the medical transport;
33.23 b) position of the medical transport;
33.24 c) number and type of vehicles in the medical transport;
33.25 d) intended route;

Section IV. – Safety communications [Wordt voorlopig toegepast per 01-01-2013]

33.30A [Wordt voorlopig toegepast per 01-01-2013] § 14 The following terms apply:
a) the safety announcement is a digital selective call using a safety call format in the bands used for terrestrial radiocommunication or a safety message format, in which case it is relayed through space stations;
b) the safety call is the initial voice or text procedure;
c) the safety message is the subsequent voice or text procedure. (WRC-07)
33.31 § 15 1) In a terrestrial system, safety communications consist of a safety announcement, transmitted using digital selective calling, followed by the safety call and message transmitted using radiotelephony, narrow-band direct-printing or data. The announcement of the safety message shall be made on one or more of the distress and safety calling frequencies specified in Section I of Article 31 using either digital selective calling techniques and the safety call format, or radiotelephony procedures and the safety signal. (WRC-07)
33.31A 2) However, in order to avoid unnecessary loading of the distress and safety calling frequencies specified for use with digital selective calling techniques:
a) safety messages transmitted by coast stations in accordance with a predefined timetable should not be announced by digital selective calling techniques;
b) safety messages which only concern vessels sailing in the vicinity should be announced using radiotelephony procedures. (WRC-07)
33.31B 3) In addition, ship stations not equipped for digital selective calling procedures may announce a safety message by transmitting the safety call by radiotelephony. In such cases the announcement shall be made using the frequency 156.8 MHz (VHF channel 16), while taking into account that other stations outside VHF range may not receive the announcement. (WRC-07)
33.31C 4) In the maritime mobile service, safety messages shall generally be addressed to all stations. In some cases, however, they may be addressed to a particular station. When using digital selective calling techniques, the safety announcement shall indicate which frequency is to be used to send the subsequent message and, in the case of a message to all stations, shall use the “All Ships” format setting. (WRC-07)
33.32 § 16 1) In the maritime mobile service, the safety message shall, where practicable, be transmitted on a working frequency in the same band(s) as those used for the safety announcement or call. A suitable indication to this effect shall be made at the end of the safety call. In the case that no other option is practicable, the safety message may be sent by radiotelephony on the frequency 156.8 MHz (VHF channel 16). (WRC-07)
33.32A 2) In the maritime mobile-satellite service, a separate safety announcement or call does not need to be made before sending the safety message. However, if available, the appropriate network priority access settings should be used for sending the message. (WRC-07)
33.33 § 17 The safety signal consists of the word SECURITE. In radiotelephony, it shall be pronounced as in French.
33.34 § 18 1) The safety call format or the safety signal indicates that the calling station has an important navigational or meteorological warning to transmit. (WRC-07)
33.34A 2) Messages from ship stations containing information concerning the presence of cyclones shall be transmitted, with the least possible delay, to other mobile stations in the vicinity and to the appropriate authorities through a coast station, or through a rescue coordination centre via a coast station or an appropriate coast earth station. These transmissions shall be preceded by the safety announcement or call. (WRC-07)
33.34B 3) Messages from ship stations, containing information on the presence of dangerous ice, dangerous wrecks, or any other imminent danger to marine navigation, shall be transmitted as soon as possible to other ships in the vicinity, and to the appropriate authorities through a coast station, or through a rescue coordination centre via a coast station or an appropriate coast earth station. These transmissions shall be preceded by the safety announcement or call. (WRC-07)
33.35 § 19 1) The complete safety call should consist of the following, taking into account Nos. 32.6 and 32.7:
the safety signal “SECURITE”, spoken three times;
the name of the called station or “ALL STATIONS”, spoken three times;
the words “THIS IS”;
the name of the station transmitting the safety message, spoken three times;
the call sign or any other identification;
the MMSI (if the initial announcement has been sent by DSC),
followed by the safety message or followed by the details of the channel to be used for the message in the case where a working channel is to be used.
In radiotelephony, on the selected working frequency, the safety call and message should consist of the following, taking into account Nos. 32.6 and 32.7:
the safety signal “SECURITE”, spoken three times;
the name of the called station or “ALL STATIONS”, spoken three times;
the words “THIS IS”;
the name of the station transmitting the safety message, spoken three times;
the call sign or any other identification;
the MMSI (if the initial alert has been sent by DSC);
the text of the safety message. (WRC-12)
33.36 2) In narrow-band direct-printing, the safety message shall be preceded by the safety signal (see No. 33.33), and the identification of the transmitting station.
33.37 § 20 1) Error correction techniques in accordance with relevant ITU-R Recommendations shall be used for safety messages by direct-printing telegraphy. All messages shall be preceded by at least one carriage return, a line feed signal, a letter shift signal and the safety signal SECURITE.
33.38 2) Safety communications by direct-printing telegraphy should normally be established in the broadcast (forward error correction) mode. The ARQ mode may subsequently be used when it is advantageous to do so.
33.38A § 20A 1) Ship stations in receipt of a safety announcement using digital selective calling techniques and the “All Ships” format setting, or otherwise addressed to all stations, shall not acknowledge. (WRC-07)
33.38B 2) Ship stations in receipt of a safety announcement or safety call and message shall monitor the frequency or channel indicated for the message and shall listen until they are satisfied that the message is of no concern to them. They shall not make any transmission likely to interfere with the message. (WRC-07)
