Complaints by broadcasters about other station operations out of compliance are handled by the FCC's Spectrum Enforcement Division of the Enforcement Bureau. Complaints should be made in writing and sent to:
Federal Communications Commission
Enforcement Bureau
Spectrum Enforcement Division
45 L Street NE
Washington DC 20554
The complaint should include the call sign and address of the station experiencing the interference, the telephone number of a contact person for that station, the frequency on which the complaining station operates, a detailed description of the nature of the interference, including the duration and frequency of the occurrence of interference, the call sign and address of the station believed to be the source of the interference, the frequency on which the alleged interfering station operates, the provision of the Communications Act, rule, order or station authorization believed to have been violated by the alleged source of the interference. Any documentation supporting the alleged existence and cause of the interference. Once a complaint is filed, the FCC will not discuss the status of an enforcement action, even with the impacted broadcaster making the complaint.
Answer revised to reflect the change of address of FCC Headquarters.
