  1. Thanks! I'll give it a shot. Since I only have the issue when running the video signal through these FCs I am curious to know if they are changing the levels even if there isn't much I can do about it.
  2. I have been battling a difficult video issue with my Attitude V2 goggles for a few months now and came across this site while researching the details of the fatshark rx modules. Hopefully someone can give me some direction in further troubleshooting. I have 2 sets of fatshark attitude v2 goggles. On both sets I have removed the FS rx module and added a female pin header to accept newer diversity modules. I have a eachine pro58 and a realacc5808 module. I have been using these goggles/modules for over a year with no trouble with several quads with and without OSD. I recently built a new fpv quad with an FC with built in OSD and noticed I'm getting distortions in the video that fluctuate with the lighting conditions in the image. I initially tried various parts swaps, multiple FCs, cams, vtx, and different receivers; and it always came down to any FC/OSD I purchased this year have the issue (4 of them) and anything older works fine. I have a boscam fpv watch and the image looks perfect on it all the time. Also a DVR connected to the goggles records the image fine. But when I use these newer FC/OSD I get this distortion in the screens of the goggles. I purchased an original Fatshark rx module and board its soldered to and put that in my goggles. The issue went away. So I believe there is some compatibility issues with my diversity rx modules and newer OSDs on race quad FCs. I thought it might be a vsync issue but am not sure or know how to check. Video of the issue below: I found this post, and some of the info looks like it may apply to my issue. Perhaps a coupling cap on the rx signal would help me?
