I have heard but not read that WW2 Army communicators would stab bayonets into the ground during island hoping missions and use audio amplifiers as if they were transceivers to talk up to 10 miles. This fascinates me to no end. I have also seen experimenters/hams drive ground rods in the ground and pick up VLF signals with some nice signals. All of this is possible if you don't have some noise makers close by. I plan on doing this experiment in my area but we have lots of clay and very little moisture penetrates that clay. We'll see how it works. I like to read authoritative articles on things like this so if you find some point them out to me. I have seen very little except just to talk about it.
