Hi Jay and LF,
 
yes, certainly another big VLF signal, up to 10 mV/m here. And with truly global coverage - look at the near-realtime VLF spectrograms from the Worldwide Lightning Location Network: http://webflash.ess.washington.edu/ .
 
I have posted some plots and thoughts about the remarkably different diurnal fading characteristics on the two DHO38 channels (23.4 vs. 18.5 kHz) - see http://people.freenet.de/df6nm/vlf/vlf_DHO_dualfreq.htm .
 
73 and best wishes to all
Markus, DF6NM

and this with heavy static at 0230Z. Will check tomorrow morning when condx are

One heck of a signal!
