Or buy the k-Line camera car and broadcast live to your TV.
Clem, I'd be curious about the output quality of the K-line of 2003 compared to the stuff being made today. I haven't been able to find any demonstration videos of this car in action.
I built my camera car using more modern and customization equipment that the Drone FPV flyers have been using for a while. It uses one of 40 channels the 5.8GHz band that has very low interference, and you can choose from many different cameras, viewing angles, transmitters, receivers and antennas.
I was able to build my camera car for about $75 and it plugs into any TV with a composite video input: https://ogrforum.com/...35#72805549098596735
