Hello Roelof, Daniele, LF,

Yes, it works.
Before i started with the VLF stuff in February 2010 i did tests with LF 
active antennas, battery supplied, and signal transfer by fiber optic 
cables. Actually it worked well with a single BF862 with the TX LED in 
the drain-to-plus stage and a 9V battery. This was an interesting 
alternative.
But later i started with the LF grabber and so it becomes inpractical 
since i don't want to replace a battery all the time and thought a solar 
module might be covered by snow in winther and so on...
Nice stuff to experiment. Anyway you have to be in a quiet location but 
noise transfer on a coax screen was history... It also worked on a multi 
turn loop which i used in France last year...
