 USA to propose additional sharing of 10 GHz ham band

The *ARRL* report the the USA is to propose the use of 9.9-10.5 GHz for the
Earth Exploration Satellite Service

US proposal for World Radiocommunication Conference 2015 (WRC-15) Agenda
Item 1.12 — to expand the Earth Exploration Satellite Service (EESS) in the
vicinity of 10 GHz — supports allocating an additional 600 MHz of spectrum
to the EESS (active) as a primary allocation in the frequency band 9.9-10.5
GHz, with certain limitations.

The Amateur and Amateur-Satellite services have secondary allocations of
10.0-10.5 GHz and 10.45-10.5 GHz, respectively; the only current primary
allocation is to Radiolocation. A study conducted by a Working Party of the
International Telecommunication Union Radiocommunication Sector (ITU-R)
concluded that the interference potential of EESS (active) to Amateur Radio
was limited to very brief and infrequent periods.

“In this hotly contested frequency range, the best we can hope for is that
sharing partners will be compatible with continued amateur access, and that
is the case here,” ARRL CEO David Sumner, K1ZZ, commented.

EESS use of the 9900-10,500 MHz band would be limited to systems requiring
necessary bandwidths greater than 600 MHz that cannot be fully accommodated
within the 9300–9900 MHz band.
