/////////////////////////////////////////// Minimal Change in Latest Australian Radiofrequency Spectrum Plan: Posted: 09 Jan 2017 04:14 PM PST http://www.eham.net/articles/38388 The latest Australian Radiofrequency Spectrum Plan -- ARSP 2017 -- was published on the Australian Communications and Media Authority's (ACMA) website on 3 January 2017. It was registered by the ACMA on 20 December 2016 and came into effect the next day, with a commencement date of 1 January 2017. Only minimal changes have been made to the previous Spectrum Plan, principally those arising from the outcomes of the 2015 World Radiocommunication Conference -- WRC-15. Most of the updates involve changes to Footnotes relating to specific allocations, while relatively few comprise changes to allocations. Of chief interest to Australian amateurs is the addition of the allocation of a 15 kHz band for the Amateur Service at 5351.5-5366.5 kHz, now widely known as the 60 metre band. This was approved at WRC-15 as a word-wide Amateur band. The WRC set different maximum radiated power specifications applying in different regions and countries, ranging from 15 watts effective isotropic radiated power (eirp) to 25 W eirp. Specifying 'eirp' takes account of the efficiency of different antenna systems, which can be rather inefficient at these frequencies. In Australia, Footnote 133B in the Spectrum Plan specifies 15 W eirp. The only other update to the Spectrum Plan of interest to amateurs is the addition of Radiolocation as a primary service in the 77.5-78 GHz band. The Amateur and Amateur-satellite services are also primary in this band. The new primary service is limited to short-range radar for ground-based applications, including automotive radar, according to the updated Footnote, no. 559B. Sharing studies conducted for the ITU over recent years demonstrated that the two services could reasonably co-exist as primary allocations. /////////////////////////////////////////// Talking About the Importance of Amateur Radio with Ken Howard: Posted: 09 Jan 2017 04:13 PM PST http://www.eham.net/articles/38387 Talking About the Importance of Amateur Radio with Ken Howard: /////////////////////////////////////////// Amateur Radio Roundtable -- Martin F.
