Mike G3XDV is probably right that the changes are more likely changes in the "environmental losses" due to >>wet trees and buildings. I agree with Alan and Mike on the loss thing... My measurements s
Hi Mike (and Mike), I have considered doing some longer term measurements here. I did spend several weeks in my early career doing 4 probe measuements on silicon wafers and ingots. I have this naggin

IŽam mesuring ground conductivity over almost 1 year regularly today it was 15,6 Ohm / m ( measured with 16Volt@ 50Hz ) I try to built a measuring device with other frequency , somthing odd ( no mult
