Introduction

My name is Dionysios Dimakos (SV1ZJ), I am 38 years old and I reside in Athens, Greece.  My major is electronic engineering. 

Since 1991, I have been involved – as an amateur - in monitoring and recording the magnetic field variations, aiming to trace earthquake precursors.  For this purpose, I have constructed and tested many different circuits and sensors.

It is a fact that the major problem during measurements is created by the use itself of electric devices, as well as the power lines.
