In November 2002, the Commission adopted new frequency coordination procedures for the filing and licensing of most fixed point to point aural and TV broadcast stations. The new Rules became effective on October 16, 2003 and immediately placed new burdens on AM, FM and TV stations owners. CTI can provide detailed interference analysis for aural STL facilities including the appropriate engineering studies to avoid interference to other users. CTI also provides notification, wherein the proposed frequency usage determined from the interference analysis is forwarded to all existing licensees and applicants whose facilities could affect or be affected by the proposal. This notification is called a "Prior Coordination Notice" or "PCN", and contains all of the technical operating parameters of the proposed system. Completion and filing of FCC 601 applications is also provided.
