Drone Company Agrees to Pay Fine for Violating FCC RF Rules

Horizon Hobby agreed to pay a $35,000 fine and implement a compliance plan to end an FCC Enforcement Bureau investigation of whether it sold audio/video transmitters for use with drones that weren't compliant with rules. “Horizon Hobby admits that it marketed AV transmitters that did not comply with the Commission’s equipment marketing rules,” said a consent decree released Thursday. RF devices must “comply with the Commission’s technical requirements and do not interfere with authorized communications,” the bureau said. “Because the noncompliant AV transmitters could operate in bands that are reserved for important operations, including Federal Aviation Administration Terminal Doppler Weather Radar, they must not be marketed or operated by anyone. Moreover, entities that rely on amateur frequencies in operating compliant AV transmitters must have an amateur license and otherwise comply with all applicable laws.” Horizon Hobby operates several websites that advertise and sell fully assembled drones, parts and accessories to hobbyists, including for use in drone racing, the bureau said: the company stopped selling the noncompliant transmitters after receiving a letter of inquiry in December. It didn’t comment.
