Hello,
@George John Drobnock
Thank you for this very interesting article!
But someone said it works with a 30 m wire antenna, too...
I hope the writer is answering to me soon.
@Thomas Ashcraft
What circut did you use to receive this VLF-emessions?
I'm interested in this setup.
Thank you in anticipation
Many greetings
J. Portik
