These are very useful to see if other people are receiving the same signals as you are, or if what you see is actually local QRM of various kinds. In DL for example there is DF6NM's grabber page at http://www.mydarc.de/df6nm/vlf/vlfgrabber.htm, and DK7FC's http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html both currently in regular use. In the UK, Paul Nicholson maintains plots of the VLF spectrum at http://abelian.org/vlf/spectrum.shtml with an extended frequency range from 0 - 85kHz. There is also live streaming audio from the lower "natural radio" part of the spectrum from this site. Cheers, Jim Moritz 73 de M0BMU
