The Enforcement Bureau has two divisions responsible for handling broadcast complaints. The Investigations and Hearings Division  is responsible for resolving complaints of non-technical broadcast violations such as complaints alleging broadcast of obscene, profane and/or indecent material, violations of the FCC's rules regarding broadcast of hoaxes, licensee-conducted contests, broadcast of telephone conversation, and public inspection file requirements.
The Spectrum Enforcement Division  resolves complaints of technical violations such as unauthorized operation of a broadcast station, violation of the Emergency Alert System (EAS) rules, antenna structure registration, marking and lighting rules, and operation with excessive power or at an unauthorized location.
