Hi Mike,
please send me Your e-mail- adress.
then I will send You my collected datas ( Exel ) which can be transformed
into a plot ( as far as I know ...)
Also could provide diagram / setup for measurements

Subject: LF: RE: Soil Conductivity Measurement
Uwe, I would be very interested in a plot of how the conductivity has
varied over the year and in what the largest variation of maximum to
minimum that you have found?
It would also be useful to measure at a frequency closer to 136Khz for
comparison purposes? It would have to be at a frequency away from
interference and the test signal would have to be strong enough to
overcome interference.
Has anyone on the list experience in measuring ground conductivity at
such frequencies?
Mike – G3LHZ
I´am 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
multibles from 50Hz, thinking about 111 Hz - )
and automatic daily measurements ( at present times done manually)
Would like to discuss about it
Uwe, DK1KQ
