VLF,

There are strange transmissions near 12.4, 13.3 and 15.6 kHz, narrow band, very strong here in Heidelberg http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html and also in Iceland http://simnet.is/halldorgudmunds/TF3HZ_VLFgrabber/index.html, also very clear at http://www.ok2bvg.cz/vlfgrabber/ and others.

Does anybody know what it is? Looks different to the often seen staircases during transmitter tests...

Unfortunately many VLF grabbers are paused / OFF these times...

Must be local I can't see anything unusual and the noise is low at KM39gc
