Frequency coordinator
In 1982, the United States Congress provided the Federal Communications Commission (FCC) the statutory authority to use frequency coordinators to assist in developing and managing the Private Land Mobile Radio (PLMR) spectrum. Frequency coordinators, in this case, are private organizations that have been certified by the Commission to recommend the most appropriate frequencies for applicants in the designated Part 90 radio services. This frequency coordination process is intended to make more efficient use of the PLMR spectrum for the benefit of all members of the public. In general, applications for new frequency assignments, changes to existing facilities or operation at temporary locations must include a showing of frequency coordination.
