Thanks Southerndevgirl, I am a certified electronic technician and have a second class FCC license and worked on aircraft equipment in my past life. Understand digital but it was boring love analog so I understand completely the equipment and a functionality of it. Yes a step up DC to DC converter would be useful but while underway we will be using the inverter which supplies AC and when plugged into shore power it's taken care of. This is a simple system and I'm not looking for anything but being able to view a broader spectrum than what I have now with a little black and white camera. I have the same system in my house and it functions well for our needs.
