I recently built a Fly-back Driver with a fly-back transformer and a primary voltage input of 12 volts and the arcs are about an inch long ( i don't know the exact output voltage because I don't have the ability to measure it ). I have heard that in the 1900's they used arcs to transmit Morse. I want to replicate this. I am wondering how I would hook up the antennas to the arc and hooking up the ground and how the arc relates to all of this. I know that there might be some legal issues to this, but I live in the mountains far from many people, maybe a few FM radio users but I just want to test this for a second and I will not be continuously running this, in other words don't restrict me to information because of legal issues because I know the warnings. So how should I connect the arc up to ground and the antenna and is there any other components I need for this?
