When combining E-field and H-field to maximise the S/N I have to remember to divide the strength by two. I forget to divide by two when measuring DJ8WX and DK7FC, so we have DJ8WX 762 km 0.22 fT April 12th DK7FC 882 km 0.17 fT April 14th DL3NDR 1016 km 0.03 fT March 28th DF6NM 1028 km 0.15 fT March 20th I'd guess DK7FC is rather less than 30uW, but it is really just a guess. Last night (16th/17th) 23:00 to 06:00 averaged in 39.7 uHz produced only 0.08 fT http://abelian.org/vlf/tmp/160417a.gif -- Paul Nicholson --
