USA to Propose Additional Sharing of 10 GHz Ham Band

Logo WRC RA 2015The 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.

Ofcom WRC-15 Consultation Responses

Logo WRC RA 2015The RSGB report responses to the Ofcom consultation on WRC-15 prepared by the Society and affiliated groups including AMSAT-UK are now available in the WRC-15 Special Focus section.

In addition to supporting Agenda Item 1.4 for a 5MHz allocation, the detailed responses cover amateur radio interests across several VHF and Microwave allocations. This includes amateur bands affected by other agenda items, ITU procedures for nano- and pico-satellites, and preferences for future agenda items that may be proposed for WRC-18.
