Hams on 23 Centimeters Must Protect New FAA Radars

Amateurs using the 23-centimeter band (1240-1300 MHz) need to be aware of a new generation of radar systems being deployed by the Federal Aviation Administration that operate between 1240 and 1350 MHz. The ARRL Letter reminds hams that the amateur allocation on this band is secondary to radionavigation (radar) and certain types of satellites, and that those primary users must be protected from interference. The ARRL says it is in contact with FAA engineers to determine the areas in which accommodations may be required to protect the new Common Air Route Surveillance Radar system.
