I have an amateur radio that has an NTSC video output to put the display on a larger monitor like a 7 inch LCD. The radio has a built in 2.5 inch LCD display.

I would like to run the video out from the amateur radio to a video in on the MYGIG and use the MYGIG display.

Can anyone tell me what wire(s) are for video in on the MYGIG?
