No expansion to the 14 MHz Amateur-Satellite allocation is planned.<\/p>\n<p>The IARU seeks expansion to 250 kHz of the Amateur-Satellite Service allocations at both 18 and 24 MHz.<\/p>\n<p>A harmonized allocation for the Amateur-Satellite Service is sought at 50-54 MHz, to bridge the gap between 28 MHz and 144 MHz but it should be noted the IARU plans for a harmonized 50 MHz band at WRC-18 are for the Amateur Service only not Amateur Satellites.<\/p>\n<p>The document notes that because of the crowding of the existing band 435-438 MHz with uncrewed amateur satellites and crewed space stations, it is desirable to study expansion of the band. This is <strong>exactly<\/strong> what the IARU were saying over 8 years ago, as yet they do not appear to have actually studied band expansion. See the <a href=\"https:\/\/ukamsat.files.wordpress.com\/2016\/10\/satellite-spectrum-requirements-ac-08spec.pdf\">2008 IARU Spectrum Requirements<\/a> document.<\/p>\n<p>Regarding the existing 1260-1270 MHz Amateur-Satellite Service allocation the IARU say they seek the deletion of the &#8220;Earth-to-space only&#8221; restriction. They note that WRC-2000 allocated the band 1240-1300 MHz to the radiodetermination-satellite service for space-to-space use. In addition, WRC-2000 allocated the band 1260-1300 MHz to the radiodetermination-satellite service for space-to-Earth use such as for the European Galileo positioning system. These actions do not change the Amateur and Amateur-Satellite Service allocations but present new sharing situations and potential operating restrictions.<\/p>\n<p>Due to the high level of interference from license exempt devices substitute spectrum for the Amateur-Satellite Service 2400-2450 MHz allocation is sought.<\/p>\n<p>It seems the IARU no longer any intends to seek a global Amateur-Satellite Service allocation at 3400-3410 MHz.<\/p>\n<p>There are no plans to improve the status of Amateur-Satellite allocations at 5 or 10 GHz.<\/p>\n<p>Download the Spectrum Requirements document from<br \/>\n<a href=\"http:\/\/www.iaru.org\/spectrum-requirements.html\" >http:\/\/www.iaru.org\/spectrum-requirements.html<\/a><\/p>\n<p>Download the Summary Record of the IARU Administrative Council meeting held in Vi\u00f1a del Mar, Chile, October 7-8, 2016 <a href=\"http:\/\/www.iaru.org\/administrative-council-meetings.html\" >http:\/\/www.iaru.org\/administrative-council-meetings.html<\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"\" border=\"0\" src=\"https:\/\/pixel.wp.com\/b.gif?host=amsat-uk.org&#038;blog=41081109&#038;%23038;post=30785&#038;%23038;subd=ukamsat&#038;%23038;ref=&#038;%23038;feed=1\" width=\"1\" height=\"1\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The IARU has released a revised edition of Spectrum Requirements for the Amateur and Amateur-Satellite Services.
