VLF,

A friend of me, F1BKM has told me about a= recent=20 french VLF experiment
on 3.3 kHz. It seems they crossed 300m in PS= K31 at 3.3=20 kHz.
Many photos are visible at
http://f6k= cz.free.fr/Actualites/2011/Carrieres%20Fleury/Carrieres%20Fleury.htm

Looks=20 interesting but an earth loop may be better here. But the system
i= s very=20 /p!

73, Stefan/DK7FC
