2 Hi,
My VTX is 12V powering it from the PDB that have BEC for 5V output which i used to power the camera
I've connected the lc filter before the VTX but i'm still having these annoying lines while flying.

139 what camera are you using? you need the filtering for the whole FPV system, that means VTX, Camera and OSD.
it's probably best to get something like a Demon Core PDB or Matek that comes with ready built-in LC filter before the 12V/5V voltage regulators...

2 camera is Quanum Super Mini 520TVL from HK
I have another lc filter so i'm gonna give it a try and connect one for the 12V VTX + OSD and the second for the 5V camera

2 it's a lot better after I connected the OSD to the same lc filter along with the VTX, camera is still connected directly to the PDB 5V BEC
There is still some small noise but the lines are gone, Thanks
