Has anyone tried to use two 5,8 tx on the same copter but on different channels? Let's say one for the camera operator is set to 5740Mhz and the other one for pilot fpv and OSD is set to 5840Mhz for example.
Is that possible or will they interfere?
No reason why it should not work but It would make more sense to have a cable from your monitor taking the signal to a pair of fatsharks etc. I prefer to fly using a monitor but sometimes the client wants to see the video goggles. If you want to have two separate cameras i.e. one fpv. only. then why not use a switcher. Vtx's use a lot of power so I don't recommend that as a viable idea.
I have recently been doing a lot of night flying with a Phantom and I can say that it so easy seeing the lights at a distance and then just having a quick glance down at the monitor to check the framing. I certainly don't need a two man op.
it will raise the noise floor depending how close the two tx are...... that could cause anything from more statis than it used to have on to it won't work 50'...... seperation is your friend.
