Compliance Request Report

APCO signed a Memo of Understanding (MOU) with the FCC's Compliance and Information Bureau (CIB), in conjunction with the FCC Wireless Telecommunications Bureau on June 15, 1998, aimed at improving the Commission's compliance and enforcement processes involving public safety radio services.

The agreement's main objective is to facilitate the Commission's certified Frequency Advisory Committee's (FAC) to work in concert with CIB to protect the technical and regulatory integrity of radio communications. Under the agreement, APCO will follow an FCC technical and administrative standard to collect all information relevant to process a compliance or interference matter. This allows the FCC to rely on APCO to research and verify the substance of a complaint. APCO will only refer a matter to the Commission when the interference problem cannot be resolved. The MOU greatly supports the Commission's mandates under the Telecommunications Act of 1996 and will conserve the Commission's resources it would otherwise expend in the research and verification of a licensee-filed complaint. APCO actively utilizes the resources of APCO's Local Advisors and the resources of all of the Public Safety Communications Council coordinators (PSCC), including AASHTO, FCCA, and IMSA to assist in the process of interference and compliance review.

Pursuant to FCC Rule 90.173(b), all applicants and licensees shall cooperate in the selection and use of frequencies in order to reduce interference and make the most effective use of the authorized facilities. Licensees of stations suffering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are unable to do so, the Commission may impose restrictions including specifying the transmitter power, antenna height, or area or hours of operation of the stations concerned. Further, the use of any frequency at a given geographical location may be denied when, in the judgment of the Commission, its use in that location is not in the public interest; the use of any frequency may be restricted as to specified geographical areas, maximum power, or such other operating conditions, contained in this part or in the station authorization.

The following Compliance Request Report (CRR) should be completed for interference complaints and submitted to APCO for processing. The form can be sent by email to

A copy of this report will be emailed to the address in the first email address box.
