The reception was readable (S6) but there was a lot of background noise from solar inverters and neighboring VLF transmitters (S5).
Converter used: techlib.com/electronics/VLFblockconv.htm
I left out all of the filtering because the magloop antenna is resonant, and itself a great filter.
Magloop made from 25 lead flatcable with a bunch of capacitance added to get it to resonate around 17khz.
I strung the flatcable around an existing little medium wave magloop antenna which is not working, just serving as a support.
Location: near Amsterdam, the Netherlands.
