Minimal Change in Latest Australian Radiofrequency Spectrum Plan:

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.
