LF: Re: What freq. list can you recommend

["James Moritz" <james.moritz@btopenworld.com>]

Dear Jurgen, LF Group,

As well as the frequency listings mentioned, there are several on-line 
"grabbers" showing spectrograms of VLF signals in near real-time. 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
