Hi everyone,

I have a speedybee tx800 and I have this problem:

when I turn on the radio, my viewer screen starts to go crazy, black, gray and frame images from the cam overlap. However, as soon as I cover the antenna with my whole hand, the signal returns clean and clearly visible.

Previously I had another speedybee tx800 that didn't give me any problems, after changing it to one of the same type I encountered this problem.
I also tried to change the antenna, change the cam, move the antennas of my receiver, but without success. It looks like a lack of insulation problem, but what can I do?

If the only thing different is the VTX and everything worked before you changed it I’d say contact whoever you bought from and get a new one. If it’s new and your other gear is good there’s no need for you to go crazy trying to fix it
