So i think i have worked out why i was getting slightly diagonal lines in my fpv feed, esc noise. Just wondering if there is a way to filter this out on betaflight. Here comes the fun part, i can only do it via the osd as i may of broken the micro usb port on my flight controller, i was thinking maybe it was the motors so i replaced them, and nope still noise. So the only thing i can really put it down to is the escs? oh and its a 4 in 1 esc.
I've had builds where nothing I did would fix it, nothing really bad so I just left it. The only other things I'd suggest are:
-check to make sure the base of your antenna mount isn't grounding on your carbon fibre frame
-make sure all your wires are as short as possible, twisted together and as far away as possible from any other power wires
Yes, wrap it with some black electrical tape and see if that helps. If not, you could try an LC filter. I don't like them though, sometimes it's hard to find a space to put them. Also, model of camera and vtx you are using and how they are powered might give me some more ideas
