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... 73, Stefan/DK7FC Am 11.08.2011 14:33, schrieb Roelof Bakker: > Hello Daniele, > > I have the parts on hands, but house restoration has prevented tests > so far. > I will report in due time. > > However Stefan has used an optical link with a 30 cm active whip. > So, it certainly will work. > > 73, > Roelof
