Note by the Secretariat

This revision of the Radio Regulations, complementing the Constitution and the Convention ofthe International Telecommunication Union, incorporates the decisions of the World Radiocom-munication Conferences of 1995 (WRC-95) and of 1997 (WRC-97). The provisions of theseRegulations apply provisionally as from 1 January 1999, unless otherwise specified (see alsoArticle S59 of this edition).

In preparing the Radio Regulations, edition of 1998, the Secretariat made editorial changes,where appropriate, to reflect:

– the ITU structural changes (world administrative radio conference to world radiocom-munication conference, CCIR to ITU-R, IFRB to the Radiocommunication Bureau,Administrative Council to Council, etc.);

– the replacement of ex-CCIR Reports by ITU-R Recommendations;

– the renumbering of Radio Regulation provisions resulting from the simplification of theRadio Regulations.

The term “Member(s)” has been replaced by the term “Member State(s)‡” to correspond with theterminology employed currently within the ITU. The symbol “‡” indicates that this replacementwas made by the Secretariat.

In addition, the term “the Bureau” has been used to refer to the Radiocommunication Bureau.

The following references to texts of these Radio Regulations appear in bold type:

– Articles, e.g. Article S52;

– Provision numbers, e.g. No. S5.344;

– Article table numbers, e.g. Table S22-2;

– Appendices, e.g. Appendix S30A;

– Resolutions, e.g. Resolution 46 (Rev.WRC-97);

– Recommendations, e.g. Recommendation 515 (Rev.WRC-97).

References to provision numbers which are not preceded by the letter “S” (usually after anoblique stroke in the case of double references) refer to provisions of the Radio Regulations,edition of 1990, revised in 1994.

As Articles S5, S21 and S22 applied provisionally as from 1 January 1997, they were publishedpreviously in Volume 4 of the Radio Regulations, Geneva, 1996. Where provisions in theseArticles were modified by the World Radiocommunication Conference (Geneva, 1997), this hasbeen indicated by the addition of “(WRC-97)” at the end of the text of the provision. Similarly,those provisions in these Articles which were abrogated by WRC-97 are shown by the additionof “ (SUP - WRC-97)” following the provision number.

Abbreviations have generally been used for the names of world administrative radio conferencesand world radiocommunication conferences. These abbreviations are shown on the next page.

APPENDIX S1

Classification of emissions and necessary bandwidths

(See Article S2)

§ 1 1) Emissions shall be designated according to their necessary bandwidth andtheir classification as explained in this Appendix.

2) Formulae and examples of emissions designated in accordance with thisAppendix are given in Recommendation ITU-R SM.1138. Further examples may be provided inother ITU-R Recommendations. These examples may also be published in the Preface to theInternational Frequency List.

Section I – Necessary bandwidth

§ 2 1) The necessary bandwidth, as defined in No. S1.152 and determined inaccordance with the formulae and examples, shall be expressed by three numerals and one letter.The letter occupies the position of the decimal point and represents the unit of bandwidth. Thefirst character shall be neither zero nor K, M or G.

2) Necessary bandwidths1:

between 0.001 and 999 Hz shall be expressed in Hz (letter H);

between 1.00 and 999 kHz shall be expressed in kHz (letter K);

between 1.00 and 999 MHz shall be expressed in MHz (letter M);

between 1.00 and 999 GHz shall be expressed in GHz (letter G).

3) For the full designation of an emission, the necessary bandwidth, indicated infour characters, shall be added just before the classification symbols. When used, the necessarybandwidth shall be determined by one of the following methods:

3.1) use of the formulae and examples of necessary bandwidths and designation of correspond-ing emissions given in Recommendation ITU-R SM.1138;

3.2) computation, in accordance with other ITU-R Recommendations;

3.3) measurement, in cases not covered by § 3.1) or 3.2) above.

_______________1 Examples:

0.002 Hz = H002 6 kHz = 6K00 1.25 MHz = 1M25

0.1 Hz = H100 12.5 kHz = 12K5 2 MHz = 2M00

25.3 Hz = 25H3 180.4 kHz = 180K 10 MHz = 10M0

400 Hz = 400H 180.5 kHz = 181K 202 MHz = 202M

2.4 kHz = 2K40 180.7 kHz = 181K 5.65 GHz = 5G65

Notes in the table of transmitter frequency tolerances

1 For coast station transmitters used for direct-printing telegraphy or for data transmission, the tolerance is:

– 5 Hz for narrow-band phase-shift keying;

– 15 Hz for frequency-shift keying for transmitters in use or installed before 2 January 1992;

– 10 Hz for frequency-shift keying for transmitters installed after 1 January 1992.

2 For coast station transmitters used for digital selective calling, the tolerance is 10 Hz. This tolerance applies totransmitters installed after 1 January 1992 and to all transmitters after the date of full implementation of theGMDSS (see Resolution 331 (Rev.WRC-97)).

3 For ship station transmitters used for direct-printing telegraphy or for data transmission, the tolerance is:

– 5 Hz for narrow-band phase-shift keying;

– 40 Hz for frequency-shift keying for transmitters in use or installed before 2 January 1992;

– 10 Hz for frequency-shift keying for transmitters installed after 1 January 1992.

4 For ship station transmitters used for digital selective calling, the tolerance is 10 Hz. This tolerance applies totransmitters installed after 1 January 1992 and to all transmitters after the date of full implementation of theGMDSS (see Resolution 331 (Rev.WRC-97)).

5 If the emergency transmitter is used as the reserve transmitter for the main transmitter, the tolerance for shipstation transmitters applies.

6 In countries covered by the North American Regional Broadcasting Agreement (NARBA) the tolerance of20 Hz may continue to be applied.

7 For single-sideband radiotelephone transmitters except at coast stations, the tolerance is:

– 50 Hz in the bands 1 606.5 (1 605 Region 2)-4 000 kHz and 4-29.7 MHz, for peak envelope powers of 200 Wor less and 500 W or less, respectively;

– 20 Hz in the bands 1 606.5 (1 605 Region 2)-4 000 kHz and 4-29.7 MHz, for peak envelope powers above200 W and 500 W, respectively.

8 For radiotelegraphy transmitters with frequency-shift keying the tolerance is 10 Hz.

9 For coast station single-sideband radiotelephone transmitters the tolerance is 20 Hz.

10 For single-sideband transmitters operating in the frequency bands 1 606.5 (1 605 Region 2)-4 000 kHz and4-29.7 MHz which are allocated exclusively to the aeronautical mobile (R) service, the tolerance on the carrier(reference) frequency is:

a) for all aeronautical stations, 10 Hz;

b) for all aircraft stations operating on international services, 20 Hz;

c) for aircraft stations operating exclusively on national services, 50 Hz*.

11 Not used.

12 For A1A emissions the tolerance is 50 × 10–6.

13 For transmitters used for single-sideband radiotelephony or for frequency-shift keying radiotelegraphy thetolerance is 40 Hz.

14 For radiobeacon transmitters in the band 1 606.5 (1 605 Region 2)-1 800 kHz the tolerance is 50 × 10–6.

_______________* NOTE – In order to achieve maximum intelligibility, it is suggested that administrations encourage the reductionof this tolerance to 20 Hz.

APS2 11

15 For A3E emissions with carrier power of 10 kW or less the tolerance is 20 × 10–6, 15 × 10–6 and 10 × 10–6in the bands 1 606.5 (1 605 Region 2)-4 000 kHz, 4-5.95 MHz and 5.95-29.7 MHz respectively.

16 For A1A emissions the tolerance is 10 × 10–6.

17 Not used.

18 Not used.

19 For ship station transmitters in the band 26 175-27 500 kHz, on board small craft, with a carrier power notexceeding 5 W in or near coastal waters and utilizing A3E or F3E and G3E emissions, the frequency tolerance is40 × 10–6.

20 The tolerance is 50 Hz for single-sideband radiotelephone transmitters, except for those transmitters operating inthe band 26 175-27 500 kHz, and not exceeding a peak envelope power of 15 W, for which the basic tolerance of40 × 10–6 applies.

21 It is suggested that administrations avoid carrier frequency differences of a few hertz, which cause degradationssimilar to periodic fading. This could be avoided if the frequency tolerance were 0.1 Hz, a tolerance whichwould be suitable for single-sideband emissions* .

22 For non-vehicular mounted portable equipment with a transmitter mean power not exceeding 5 W, the toleranceis 40 × 10–6.

23 For transmitters of a mean power of 50 W or less operating at frequencies below 108 MHz a tolerance of3 000 Hz applies.

24 In the case of television stations of:

– 50 W (vision peak envelope power) or less in the band 29.7-100 MHz;

– 100 W (vision peak envelope power) or less in the band 100-960 MHz;

and which receive their input from other television stations or which serve small isolated communities, it maynot, for operational reasons, be possible to maintain this tolerance. For such stations, the tolerance is 2 000 Hz.

For stations of 1 W (vision peak envelope power) or less, this tolerance may be relaxed further to:

– 5 kHz in the band 100-470 MHz;

– 10 kHz in the band 470-960 MHz.

25 For transmitters for system M (NTSC) the tolerance is 1 000 Hz. However, for low power transmitters using thissystem Note 24 applies.

26 For multi-hop radio-relay systems employing direct frequency conversion the tolerance is 30 × 10–6.

27 Not used.

28 For a channel spacing of 50 kHz the tolerance is 50 × 10–6.

29 These tolerances apply to channel spacings equal to or greater than 20 kHz.

30 Not used.

31 For transmitters used by on-board communication stations a tolerance of 5 × 10–6 shall apply.

_______________* NOTE – The single-sideband system adopted for the bands exclusively allocated to HF broadcasting does notrequire a frequency tolerance less than 10 Hz. The above-mentioned degradation occurs when the ratio of wanted-to-interfering signal is well below the required protection ratio. This remark is equally valid for both double- andsingle-sideband emissions.

12 APS2

32 For non-vehicular mounted portable equipment with a transmitter mean power not exceeding 5 W the toleranceis 15 × 10–6.

33 Where specific frequencies are not assigned to radar stations, the bandwidth occupied by the emissions of suchstations shall be maintained wholly within the band allocated to the service and the indicated tolerance does notapply.

34 Not used.

35 Not used.

36 In applying this tolerance administrations should be guided by the latest relevant ITU-R Recommendations.

APPENDIX S3

Table of maximum permitted spuriousemission power levels

(See Article S3)

1 The following sections indicate the maximum permitted levels of spurious emissions,in terms of power as indicated in the tables, of any spurious component supplied by a transmitterto the antenna transmission line. Section I is applicable until 1 January 2012 to transmittersinstalled on or before 1 January 2003; Section II is applicable to transmitters installed after1 January 2003 and to all transmitters after 1 January 2012. This Appendix does not cover out-of-band emissions. Out-of-band emissions are dealt with in No. S4.5.

2 Spurious emission from any part of the installation, other than the antenna and itstransmission line, shall not have an effect greater than would occur if this antenna system weresupplied with the maximum permitted power at that spurious emission frequency.

3 These levels shall not, however, apply to emergency position-indicating radiobeacon(EPIRB) stations, emergency locator transmitters, ships’ emergency transmitters, lifeboat trans-mitters, survival craft stations or maritime transmitters when used in emergency situations.

4 For technical or operational reasons, more stringent levels than those specified maybe applied to protect specific services in certain frequency bands. The levels applied to protectthese services, such as safety and passive services, shall be those agreed upon by the appropriateworld radiocommunication conference. More stringent levels may also be fixed by specificagreement between the administrations concerned. Additionally, special consideration oftransmitter spurious emissions may be required for the protection of safety services, radioastronomy and space services using passive sensors. Information on the levels of interferencedetrimental to radio astronomy, Earth exploration satellites and meteorological passive sensing isgiven in the most recent version of Recommendation ITU-R SM.329.

5 Spurious emission limits for combined radiocommunication and information tech-nology equipment are those for the radiocommunication transmitters.

Section I – Spurious emission limits for transmitters installed onor before 1 January 2003 (valid until 1 January 2012)

6 The measurement methods for radar systems should be guided by Recommen-dation ITU-R M.1177. For those radar systems for which acceptable methods of measurement donot exist, the lowest practicable power of spurious emission should be achieved.

TABLE I (end)

Section II – Spurious emission limits for transmitters installed after 1 January 2003and for all transmitters after 1 January 2012

Application of these limits

7 The frequency range of the measurement of spurious emissions is from 9 kHz to110 GHz or the second harmonic if higher.

8 Guidance regarding the methods of measuring spurious emissions is given in themost recent version of Recommendation ITU-R SM.329. The e.i.r.p. method specified in thatRecommendation should be used when it is not possible to measure the power supplied to theantenna transmission line. Additionally, the e.i.r.p. method may need some modification forspecial cases, e.g. beam-forming radars.

9 Guidance regarding the methods of measuring spurious emissions from radarsystems is given in the most recent version of Recommendation ITU-R M.1177. The referencebandwidths required for proper measurement of radar spurious emissions should be calculatedfor each particular radar system. Thus, for the three general types of radar pulse modulationutilized for radionavigation, radiolocation, acquisition, tracking and other radiodeterminationfunctions, the reference bandwidth values should be:

– for fixed-frequency, non-pulse-coded radar, one divided by the radar pulse length, inseconds (e.g. if the radar pulse length is 1 µs, then the reference bandwidth is 1/1 µs= 1 MHz);

– for fixed-frequency, phase coded pulsed radar, one divided by the phase chip length, inseconds (e.g. if the phase coded chip is 2 µs long, then the reference bandwidth is 1/2 µs= 500 kHz);

6 Where several transmitters feed a common antenna or closely spaced antennas on neighbouringfrequencies, every practicable effort should be made to comply with the levels specified.

7 Since these levels may not provide adequate protection for receiving stations in the radioastronomy and space services, more stringent levels might be considered in each individualcase in the light of the geographical position of the stations concerned.

8 These levels are not applicable to systems using digital modulation techniques, butmay be used as a guide. Values for these systems may be provided by the relevantITU-R Recommendations, when available (see Recommendation 66 (Rev.WRC-97)).

9 These levels are not applicable to stations in the space services, but the levels of their spuriousemissions should be reduced to the lowest possible values compatible with the technical andeconomic constraints to which the equipment is subject. Values for these systems may beprovided by the relevant ITU-R Recommendations, when available (see Recommendation 66Rev.WRC-97)).

16 APS3

– for frequency modulated (FM) or chirped radar, the square root of the quantity obtained bydividing the radar bandwidth in MHz by the pulse length, in seconds (e.g. if the FM is from1 250 MHz to 1 280 MHz or 30 MHz during the pulse of 10 µs, then the reference band-width is (30 MHz/10 µs)1/2 = 1.73 MHz).

For those radar systems for which acceptable methods of measurement do not exist, the lowestpracticable power of spurious emission should be achieved.

10 The spurious emission levels are specified in the following reference bandwidths:

– 1 kHz between 9 kHz and 150 kHz

– 10 kHz between 150 kHz and 30 MHz

– 100 kHz between 30 MHz and 1 GHz

– 1 MHz above 1 GHz.

As a special case, the reference bandwidth of all space service spurious emissions should be4 kHz.

11 For the purpose of setting limits, all emissions, including harmonic emissions,intermodulation products, frequency conversion products and parasitic emissions, which fall atfrequencies separated from the centre frequency of the emission by ± 250%, or more, of thenecessary bandwidth of the emission will generally be considered as spurious emissions.However, this frequency separation may be dependent on the type of modulation used, themaximum bit rate in the case of digital modulation, the type of transmitter and frequencycoordination factors. For example, in the case of digital (including digital broadcasting)modulation systems, broadband systems, pulsed modulation systems and narrow-band highpower transmitters, the frequency separation may need to differ from the ± 250% factor. Formultichannel or multicarrier transmitters/transponders, where several carriers may be transmittedsimultaneously from a final output amplifier or an active antenna, the centre frequency of theemission is taken to be the centre of the – 3 dB bandwidth of the transmitter or transponder andthe necessary bandwidth is taken to be the transmitter or transponder bandwidth.

12 Examples of applying 43 + 10 log (P) to calculate attenuationrequirements

Where specified in relation to mean power, spurious emissions are to be at least x dB below thetotal mean power P, i.e. – x dBc. The power P (W) is to be measured in a bandwidth wideenough to include the total mean power. The spurious emissions are to be measured in the

APS3 17

reference bandwidths given in the Recommendation. The measurement of the spurious emissionpower is independent of the value of necessary bandwidth. Because the absolute emission powerlimit, derived from 43 + 10 log (P), can become too stringent for high-power transmitters,alternative relative powers are also provided in Table II.

Example 1

A land mobile transmitter, with any value of necessary bandwidth, must meet a spuriousemission attenuation of 43 + 10 log (P), or 70 dBc, whichever is less stringent. To measurespurious emissions in the frequency range between 30 MHz and 1 GHz, Recommenda-tion ITU-R SM.329-7 recommends 4.1 indicates the use of a reference bandwidth of 100 kHz.For other frequency ranges, the measurement must use the appropriate reference bandwidthsgiven in recommends 4.1.

With a measured total mean power of 10 W:

– Attenuation relative to total mean power = 43 + 10 log (10) = 53 dBc.

– The 53 dBc value is less stringent than the 70 dBc, so the 53 dBc value is used.

– Therefore: Spurious emissions must not exceed 53 dBc in a 100 kHz bandwidth, orconverting to an absolute level, spurious emissions must not exceed 10 dBW – 53 dBc =_

43 dBW in a 100 kHz reference bandwidth.

With a measured total mean power of 1 000 W:

– Attenuation relative to total mean power = 43 + 10 log (1 000) = 73 dBc.

– The 73 dBc value is more stringent than the 70 dBc limit, so the 70 dBc value is used.

– Therefore: Spurious emissions must not exceed 70 dBc in a 100 kHz bandwidth, orconverting to an absolute level, spurious emissions must not exceed 30 dBW – 70 dBc =_


Example 2

A space service transmitter with any value of necessary bandwidth must meet a spuriousemission attenuation of 43 + 10 log (P), or 60 dBc, whichever is less stringent. To measurespurious emissions at any frequency, Note 10 to Table II indicates using a reference bandwidthof 4 kHz.

18 APS3

With a measured total mean power of 20 W:

– Attenuation relative to total mean power = 43 + 10 log (20) = 56 dBc.

– The 56 dBc value is less stringent than the 60 dBc limit, so the 56 dBc value is used.

– Therefore: Spurious emissions must not exceed 56 dBc in a 4 kHz reference bandwidth, orconverting to an absolute level, spurious emissions must not exceed 13 dBW – 56 dBc =_

P: mean power in watts supplied to the antenna transmission line, in accordance withNo. S1.158. When burst transmission is used, the mean power P and the mean power of anyspurious emissions are measured using power averaging over the burst duration.

PEP: peak envelope power in watts supplied to the antenna transmission line, in accordance withNo. S1.157.

dBc: decibels relative to the unmodulated carrier power of the emission. In the cases which do nothave a carrier, for example in some digital modulation schemes where the carrier is notaccessible for measurement, the reference level equivalent to dBc is decibels relative to themean power P.

10 Spurious emission limits for all space services are stated in a 4 kHz reference bandwidth.

11 For analogue television transmissions, the mean power level is defined with a specified videosignal modulation. This video signal has to be chosen in such a way that the maximum meanpower level (e.g. at the video signal blanking level for negatively modulated television systems)is supplied to the antenna transmission line.

12 All classes of emission using SSB are included in the category “SSB”.

13 Low-power radio devices having a maximum output power of less than 100 mW and intendedfor short-range communication or control purposes; such equipment is in general exempt fromindividual licensing.

15 In some cases of digital modulation (including digital broadcasting), broadband systems, pulsedmodulation and narrow-band high-power transmitters for all categories of services, there may bedifficulties in meeting limits close to ± 250% of the necessary bandwidth.
