Hi Stefan,
 
looks nice but I suspect you  have some im problem in your first stage because off the strong line at 9 KHz,Maby it's better to use a filter at the input....

Dear LF,

Daniele and others asked for the circuit of my active E field antenna that i am using for my grabber. Now i have created a pdf file where you can find the circuit and a picture of the arrangement and a spectrogram of the currently working circuit.

http://www.iup.uni-heidelberg.de/schaefer_vlf/8,97kHz%20active%20E%20field%20antenna%20by%20DK7FC.pdf

So, if you are interested or want to get some ideas for your own circuit, take a look on it. I hope the link works.

So, best 73 and maybe cu this evening there, dreamers.

Stefan/DK7FC
