[UK-CONTEST] Ground conductivity

[Giles Herbert]

For those who enjoy a challenge, some ARRL handbooks offer a method for measuring your actual conductiviry.  They use 110volts and I do not think it would meet with current safety practice in this country but if you want to see the method it is therre to see.
