edwhittle It's a way to change the channel and power of your VTX remotely from your transmitter. See this video: https://www.youtube.com/watch?v=zFb5IJpM1XU&t=257s

edwhittle It’s meant for 3D. 3D only works with two cameras. Meaning the googles need two receivers, one for each camera. Those receivers are then diversity. I doubt it’s going to be quad diversity. I bet it’s going to be one receiver port for classic one camera/left eye and the other diversity module for right eye. I’m not sure how they’d set it up to make the goggles compare ALL signals from the diversity receivers because the signal switching takes place on the diversity module itself.
