Can anyone comment on what might be causing this FPV visual interference.

It is not related to any particular location, nor does it get worse with distance.

At the end of the clip you can see that there are still lines scrolling up the screen after the motors have stopped.

Thanks
 
Dirty power would be my guess. Try an lc-filter.

Thanks a lot for posting.
I have applied the "tape mod" and it looks a lot better on the bench. Will try a test flight. Fingers crossed :)

Well how did it workout?? I don't have the same noise on my screen but using H3-2D it's impossible to isolate or even filter out the noise. May if I order all the components to make a new harness from monitor to dvr and adding a filter inline might help.
 
I didn't see a problem until your rotors turned on. I believe you need a noise filter on the DC line to your video transmitter.

On page 4 of the above linked thread, there is a post on how a user fixed it by grounding the camera connector. That way, you don't have to use tape and your camera can run on the quad's power if you want. I just tried it (my quad was already opened up for other repairs). It worked! Perfectly. I need to test it in flight.

Here is a direct link to that post

My reply was lost in the weekend data loss.
Just to add (again) for the record that the taping over of all but two of the ribbon cable wires, worked a treat.
Thanks again.
 
Glad it works!
