indirect recordings of Schumann resonances

antenna located at D64354 Reinheim/Georgenhausen  -  E 8°48'14'' N 49°50'50"

During the first recording session using the vertical field probe, some strong fundamental Schumann resonances overrides the humming backround. Due to the poor frequency response of my tape-recorder at the low end and the poblems to reproduce the 7.8Hz fundamental - the Schumann-Signal cannot shown itself. Instead the quenching of the humm indicates the pressents of a very strong VLF. The differential peaks of the changing polarity exceeds the 0dB output range of my tapedeck. I'm looking for a better equipment.
