My father, Rob, narrated this video to demostrate the problem of
intermodulation distortion when flying with groups of people in FPV. Rob is a retired engineer who spent his career doing RF design.
A group of pilots operating at 5.8 GHz are especially prone to IMD. The close proximity, high power transmitters, even spacing of the channel frequency, and poor receivers contribute to the problem. Per the video, there are some simple steps that can be taken to mitigate the issue. IMD is when two other transmitters combine and produce interference in your receiver at your desired FPV frequency.
