Hello:
I joined this site since I couldn't find much online that was definitive to the question I have.
I'm not a drone flyer...I'm an audio technician.
Long story short: Was doing a show with wireless microphones (536.150 MHz). We're a festival site, so many events going on at the same time. My show went up at 7:15. At 7:30, another went up, being taped with a drone. I had no audio problems from 7:15 - 7:30...but at 7:30, all I had was MASSIVE static! (I checked with all the venues...none were operating on my frequency...
Do some drones work on 500 - 600 MHz frequencies? I know a lot of the new ones are in the GHz range. And how wide is the range used. IE, microphones can be set at 536.150, 536.175... etc...
Thanks in advance!
Bob

Most commercially available quad-copters will use a 2.4 GHz Frequency Hopping Spread Spectrum radio control loop. I'm guessing your radio microphones are FM-FM @ the frequency you mentioned. No interference likely.
The quad-copters using the 3DR built autopilots commonly use a radio link at either 433 MHz (Europe) or 915Mhz (N. America) Also in a modulation scheme that would not interfere with another system near its frequency band.
Video downlinks are common on 1 GHz, 2.4Ghz or 5.8 GHz bands, so not likely interfering with your radio microphones..
Awesome! Thanks for the info! Now I have NO IDEA what happened! :) Good thing BBC was there for the first 5 mins of the show so they got some good audio!
