Illegal Drone Transmitters Could Interfere with Air Traffic Control, ARRL Complaint Asserts

In what it calls an “extremely urgent complaint” to the FCC, ARRL has targeted the interference potential of a series of audio/video transmitters used on unmanned aircraft and marketed as Amateur Radio equipment. In a January 10 letter to the FCC Spectrum Enforcement Division, ARRL General Counsel Chris Imlay, W3KD, said the transmitters use frequencies intended for navigational aids, air traffic control radar, air route surveillance radars, and global positioning systems.

“This is, in ARRL’s view, a potentially very serious interference problem, and it is respectfully requested that the products referenced…be investigated and removed from the marketplace immediately and that the importers be subjected to normal sanctions,” ARRL’s letter said. Some of the transmitters operate on frequencies between 1,010 and 1,280 MHz. “These video transmitters are being marketed ostensibly as Amateur Radio equipment,” the League said, “but of the listed frequencies on which the devices operate, only one, 1280 MHz, would be within the Amateur Radio allocation at 1240-1300 MHz.” Even then, ARRL said, operation there would conflict with a channel used for radio location.
