Good evening, So let me start with my set up, I have a phantom 2 with a h3-3d gimbal and a gopro hero 4 black and a gopro hero 3 black (yes i have 2 not mounted at the same time but for the testing this helps to know) a immersion 600w transmitter, a 7 channel black pearl. ok now here is the problem that I am running into. I was testing range on my immersion 600 to my black pearl and getting some distortion so i changed the transmit and receiving channel on my set up now i can't get video from the TX to the BP, I am getting signal as the screen goes from fuzzy to black when they are both turned on and connected. so the immersion is connecting to the BP i can't seem to get any video from the go pro to the immersion all of my connections are soldered and stable I can't figure out why it would just go out. I tried completely reinstalling everything and still can't get it to work. any ideas would be great. this set up did work for a week now that i have had it. just stopped working today.
