 Hi Brian,
Thanks for another great contribution to the hobby!  Your efforts are much 
appreciated.

 I've written a Windows program that calculates ground permittivity, 
conductivity, and skin depth using impedance data from a soil probe and 
vector network analyzer, such as a NanoVNA. Realistic ground parameters 
are important when comparing horizontal and vertical antenna models. 
General terrain descriptions and ground conductivity maps are much too 
coarse. Ground parameters also vary with frequency. With a soil probe 
you can determine the parameters of your local ground at the frequency 
of interest. Skin depth can help you assess the limitation of a surface 
probe when the ground is inhomogeneous.

See README.TXT for instructions. It includes references on making and 
using a soil probe.
