SB QST @ ARL $ARLB045 ARLB045 7 MHz realignment compromise makes radio history ZCZC AG45 QST de W1AW ARRL Bulletin 45 ARLB045 From ARRL Headquarters Newington CT July 11, 2003 To all radio amateurs SB QST ARL ARLB045 ARLB045 7 MHz realignment compromise makes radio history In an 11th-hour compromise, delegates to World Radiocommunication Conference 2003 (WRC-03) agreed to move broadcasters out of 7100 to 7200 kHz in Regions 1 and 3 to make room for the Amateur Service. The expanded worldwide allocation at 40 meters goes into effect on March 29, 2009. Amateurs in the US and the rest of Region 2 will continue to enjoy the 7000 to 7300 kHz band they now have, but with greatly reduced broadcasting interference. The compromise marked the first time in the history of internationally coordinated radio spectrum allocation that an HF broadcasting band was shifted to accommodate the needs of another service. The compromise cuts in half the incompatibility between amateur and broadcasting use of the 7 MHz band and doubles the 40-meter spectrum available to amateurs in Regions 1 and 3. While the result falls short of the IARU's goal of a 300-kHz worldwide exclusive band for amateurs, the cooperation of broadcasters, opposing delegates and many others was required to make a positive step for ham radio. Spectrum between 4 and 10 MHz is on the agenda for WRC-07, but further changes to 7000-7200 kHz will not be considered. The conference also dropped the international Morse code requirement, leaving individual countries to decide if they want to retain a code proficiency requirement, and adopted a number of improvements to the other international regulations for the amateur service. The delegates also agreed to allowed a secondary allocation for satellite borne synthetic aperture radars at 70 cm and made amateur call sign assignment more flexible. NNNN /EX
