Here is the method used to measure ground
conductivity as suggested by ARRL. In our case, use RF rather than 60
hz.

I think this is why people are confused. I believe that Dick

leakages.
I indeed measured the total resistance of
the aerial system (minus the coil loss) as I have explained in my e-mail. I
agree with Mike that "system loss" would have been a better _expression_ than
"earth resistance".
Has anyone measured
earth resistance alone under different conditions? If I
recall correctly,
this can be done with three earth stakes and
Kirchoff's
laws.
Indeed, but it usually done
at 50Hz. To be meaningful at LF the measurement should be performed at an LF
frequency. But I'm afraid that will not be so simple.
