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

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
