Hi Jean-Louis, LF group,
 
there is a fascinating article= on ELF propagation, which has many details on ZEVS (and also referen= ces Tom Clancy's novel):
Fraser-Smith, A.C., Bannister, P.= R., 1998: Reception of ELF signals at antipodal distances =
Radio Science 33, 83-88.=
The pdf used to be at
http://www-st= ar.stanford.edu/~acfs/82Hz.pdf
but can still be downloaded from
It also mentions a dipole orientation of 77=C2=B0 / 253=C2=B0 from Mu= rmansk, so we might expect a slightly weaker signal in Eastern= Europe.

is an excellent survey of VLF and ELF&nbs= p;phenomena, even featuring a spectrogram of an Hell-mode = ;transmission, induced by the Tromso ionospheric heater in 1982. &nbs= p;

Grazie mille Marco.
 
I knew about the Trond infos for a lon= g time. The purpose of my question was to try to identif= y some data about ZEVS coming from any other sources.
 
As you probably know, getting accurate data= about any russian system is quite a challenge (specially if it's a milita= ry system !)
