SB QST @ ARL $ARLB029 ARLB029 ARRL, AeroAstro Square Off Over 2300-2305 MHz ZCZC AG29 QST de W1AW ARRL Bulletin 29 ARLB029 From ARRL Headquarters Newington CT August 3, 2001 To all radio amateurs SB QST ARL ARLB029 ARLB029 ARRL, AeroAstro Square Off Over 2300-2305 MHz In a spectrum battle pitting Amateur Radio against a commercial interest, the ARRL and AeroAstro this week filed comments with the FCC to bolster their respective--and competing--proposals for 2300 to 2305 MHz. ARRL has petitioned to elevate the Amateur Service from secondary to primary status on the band and requested that no commercial operations be introduced. AeroAstro seeks co-primary status with the Amateur Service to accommodate a Miscellaneous Wireless Communication Service satellite-based position-monitoring system. The ARRL has characterized AeroAstro's petition as ''a Trojan horse'' and said there's no possibility that hams and an auctioned MWCS service could coordinate operations on the band. AeroAstro claims that the 1 W spread-spectrum uplinks of its proposed Satellite Enabled Notification System (SENS) and Amateur Radio can share the 5 MHz of spectrum and still protect the nearby NASA Deep Space Network. While contending that it ''does not seek to cut back current Amateur operations in the band,'' AeroAstro also called on the FCC to impose severe power and antenna limitations on hams at 2300-2305 MHz. Under the AeroAstro proposal, Amateurs would be limited to 100 W output and antennas with a beamwidth no greater than 5 degrees for ''narrowbeam'' operation such as Earth-Moon-Earth communication. For other operation, AeroAstro wants the FCC to limit amateurs to 25 W EIRP. ''This is totally unacceptable,'' the ARRL retorted in its comments, adding that the restrictions would preclude most amateur operations in the band. A co-primary allocation such as AeroAstro proposes also would make no provision to mitigate interference. The ARRL said the FCC already has made ''adequate accommodation'' for services such as the one AeroAstro has proposed ''without compromising the 2300-2305 MHz Amateur allocation.'' The ARRL concluded that technical limitations proposed for MWCS in the band ''would not be sufficient to avoid interference to sensitive Amateur receivers, and no coordinated operation between the two services is possible under the circumstances.''
