FCC reaffirms $3M fine for marketing unauthorized drone transmitters
This appears to be "video streaming" style transmitters, not an ADS-B out sort of location transmitter or anything.And it seems that HobbyKing just... hoped nothing would happen.> As spelled out in ARRL’s 2017 complaint, the ARRL Laboratory had documented that the operating frequencies of these drone TV transmitters near the 1.3 GHz amateur band were dip-switch selectable for frequencies internationally assigned for use by Aeronautical Navigation, GPS, GLONASS L1, ATC Mode “S,” as well as to both the interrogation and reply frequencies used for Air Traffic Control Air-Route Surveillance “transponder” radar systems. “Transmissions from these drone TV transmitters would have caused harmful interference to these essential Navigation and ATC Radar systems, presenting a real and dangerous threat to the safety of flight,” Carlson said.That's impressively ballsy.  I'm glad the FCC smacked them down pretty hard.  It's not like global frequency allocations aren't well known.
