This afternoon I connected DK4U's 200 meter LF wire directly to the soundcard ("line-in"), and voila - a weak but very stable signal at 82 Hz (unlike 16 2/3 and 50 Hz, which are kind of "wobbly" if one takes a close look, and definitely not a signal from a CRT monitor). A friend in Italy recently informed me about that transmission. Some interesting reading is here: http://www.vlf.it/zevs/zevs.htm . Just imagine - they produce an ERP in the "watts"-range, with two earth electrodes separated 60 km's, pushing in some 200 .. 300 Amperes to use mother earth as antenna. So, if you find no activity on LF these days (and are sure that the next T-storm is far away), just try it - it's amazing what can be seen on ELF even if it's not really amateur radio.
