Greetings. With the oversight of the EMC Committee and instructions from CEO Gallagher I filed the attached complaint yesterday with FCC. It urges enforcement action against a series of video downlink transmitters that operate at 1000 MHz and 1280 MHz. Thanks especially to Mike Gruber for the fine technical exhibit and to Kermit Carlson for shepherding this along and for his helpful edits to this document. As you can see from reading this, these devices are marketed as Amateur Radio equipment but they operate principally on non-amateur frequencies used for GLONASS GPS and FAA radars. They are not functional as bona fide Amateur Radio equipment. They are a serious hazard to air navigation and air safety and ARRL is doing a public service by filing this. Kudos to the ARRL lab. There is also a regulatory strategy being pursued here. According to Laura Smith, OET at FCC will not permit enforcement actions against deployed Part 15 devices. The theory at OET is that as soon as FCC takes an enforcement action against one Part 15 device, they will be drowned in enforcement requests with respect to others. To take no action against deployed drone video transmitters that will interfere with FAA radars and GPS however, is simply not on. So we are trying to pursue the most compelling case possible to push OET into a more responsible posture. This may be it. 73, Chris W3KD -- Christopher D.
