On June 5, 2018, the Federal Communications Commission released an Enforcement Advisory confirming that audio/ video transmitter accessories used with drones must also comply with the Commission’s Equipment Authorization rules before being marketed to U.S. customers. According to the Advisory, the FCC “has observed a growing number of websites that advertise and sell noncompliant radio accessories, specifically audio/video transmitters (AV transmitters), intended for use with drones. Noncompliant AV transmitters are illegal, and they have the potential to interfere with public safety, aviation, and other operations by Federal agencies.”
