Special WRC Report Number Three The Amateur Radio Service Gains A Band Near 500 kHz

472-479 kHz. The worldwide amateur radio service has a new frequency band, 472 to 479 kHz. It is a secondary allocation. There are other services in that portion of the spectrum that must not be interfered with by the amateur operation.The aeronautical radionavigation service is a primary service in the band 415-495 kHz in the following areas: Australia, China, the French overseas communities of Region 3, Korea (Rep. of), India, Iran (Islamic Republic of), Japan, Pakistan, Papua New Guinea and Sri Lanka. The aeronautical radionavigation service is a primary service in the band 435-495 kHz in the following areas: Armenia, Azerbaijan, Belarus, the Russian Federation, Kazakhstan, Latvia, Uzbekistan and Kyrgyzstan. The amateurs are allowed to use the band so long as it does not cause interference to this primary service or the maritime mobile service operating in the 472-479 kHz band. There are some countries that will not allow amateur radio operation in the 472-479 kHz band. The use of the frequency band 472-479 kHz in Algeria, Saudi Arabia, Azerbaijan, Bahrain, Belarus, China, Comoros, Djibouti, Egypt, United Arab Emirates, the Russian Federation, Iraq, Jordan, Kazakhstan, Kuwait, Lebanon, Libya, Mauritania, Oman, Uzbekistan, Qatar, Syrian Arab Republic, Kyrgyzstan, Somalia, Sudan, Tunisia and Yemen is limited to the maritime mobile and aeronautical radionavigation services. The amateur service shall not be used in the above-mentioned countries in this frequency band, and this should be taken into account by the countries authorizing such use.

The ITU Radio Regulations provide that radio amateurs are limited to 1 watt (e.i.r.p.) however administrations whose territory is beyond 800 kilometers from the borders of the following countries may increase the operating power to 5 watts (e.i.r.p.): Algeria, Saudi Arabia, Azerbaijan, Bahrain, Belarus, China, Comoros, Djibouti, Egypt, United Arab Emirates, the Russian Federation, Iran (Islamic Republic of), Iraq, Jordan, Kazakhstan, Kuwait, Lebanon, Libya, Morocco, Mauritania, Oman, Uzbekistan, Qatar, Syrian Arab Republic, Kyrgyzstan, Somalia, Sudan, Tunisia, Ukraine and Yemen. The change becomes effective with the adoption of the Final Acts of the Conference. Of course, it will be determined by each administration around the world as to what modes and bandwidths will be used in this portion of the spectrum and when hams in that country will have access to the spectrum. More activities from the WRC-12 will be reported at the end of the WRC. The WRC continues until 17 February. There is an effort underway to place an amateur radio agenda item on the agenda for the next WRC which will take place in 2015.

Today the WRC-12 plenary meeting went over the list of future Agenda Items (for WRC-15 and WRC-18) in second reading. I am happy to report that the meeting agreed that WRC-15 will consider a possible new secondary amateur allocation within the band 5 250 - 5 450 kHz in accordance with Resolution COM6/12 (WRC-12). Earlier today the WRC-12 Plenary came to an agreement in first reading on the text of the Resolution.
