RADIO HAM: EMF Detector Build It is not so easy.

A local Radio Amateure friend designed and built a EMF detector and I asked if he would let me have one so I could check my EMF field readings, Yes came the reply, but you will have to build it yourself.
I took about 1millisecond to respond, yes ok… and so this is that kit and how I built it.

Many thanks to John G8CQX for a fantastic bit of kit. it works well, but there is more to measuring EMF fields than meets the eye.

Many thanks
