At the time of notification of these cases the attention of the International Frequency Registra- tion Board is drawn to the above condition. 158 "' In Region 1, the use of the band 7 100-7 160 kc/s by the amateur service is authorised provided that no harmful interference is caused to the broadcast- ing service. However, in the Union of South Africa and the territory under mandate of Southwest Africa, the band 7 100-7 160 kc/s will be used exclusively for the amateur service. 159 "In Australia and the Netherlands East Indies, the band 7100-7 150 kc/s, and in China and New Zealand, the band 7 100-7 300 kc/s, may be allo- cated for the amateur service. The administrations of the countries mentioned in this note shall take all practicable steps to avoid causing any harmful inter- ference to the broadcasting service and will ensure that amateur stations do not use a peak power exceeding 100 watts. If, however, harmful interference to the broadcasting service is experienced these administrations will consider reducing the use of these bands by the amateur service. 1653 - w
