I used a 120m long wire antenna that was placed just on the ground. Since the earth losses were very high i have jut got 6W TX power out of my 300W PA. See my detailed report with many pictures and the results on: http://www.iup.uni-heidelberg.de/schaefer_vlf/Earth_antenna_120m_transmission_2km_DK7FC.pdf Today, there were transmissions at least by DJ2LF, DF6NM, DK7FC on the dreamers band. It seems we need something like a band plan soon, hi :-) Best 73 and good luck, Dreamers! 73, Stefan/DK7FC --------------000408080109030408060905 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Dear VLF,
