I have just set up a FPV system with the DJI AVL58 and some Boscam LCD screen with built-in receiver. There are a few lines on the screen traveling from the middle of the screen and upwards, when they come all the way up they disappear and it starts over again with lines appearing at the middle and going upwards. This is happening regardless of how near to the AVL58 the screen is. Even if they are an inch from each other it happens. I would have thought it was a reception issue if it were not for the fact that it happens regardless of the distance. I have the original antennas on both units, but i doubt that new antennas will make it better? Anybody that knows what this can be or has experienced a similar thing? Can it be that it is the channels that aren't exactly on the same frequency? But the picture is good aside from the mentioned problem. Or can it be something near the AVL58 on the drone that is disturbing the transmission? If so what can it be? The AVL58 is underneath the drone beside the FPV Hub kit board and the iosd Mini module.
