[TowerTalk] W7PUA Tiny Ground Probe

[David Gilbert]

I've thought about using two meshes on the surface of the ground spaced 
some distance apart.  Sweep the frequency while measuring the complex 
impedance between them.

I know for a fact that my rocky hillside lot doesn't have uniform soil 
(there are rocks down there the size of a small car), so doing multiple 
tests with the two meshes in different positions might actually be 
capable of generating some sort of profile with the right modeling software.

OpenAI Codex has become scary competent .... I wonder if it could come 
up with something like that.
