Still trying to track down why my 5.8 video system works but my 1.3 system is black screen with audio only.

Is the camera (runcam micro swift 2) the only place to select PAL or NTSC format? What would be the symptoms if the wrong format was selected?

Do the VTX or VRX have to be configured for one or the other?

My VAS 1.3 VTX and VRX didn’t come with any manual. Each have 1 button that I assume that changes channels. When I push the VTX button, it displays “9” push again and I get “d”, that’s all it displays. What is d?

The VRX cycles through 0,1,2,3,4,5,6,7,8,9,H,C,d. What are H,C,d?
