Hi Jean-Louis, LF group,
 
there is a fascinating article on ELF propagation, which has many details on ZEVS (and also references 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-star.stanford.edu/~acfs/82Hz.pdf
but can still be downloaded from
It also mentions a dipole orientation of 77° / 253° from Murmansk, so we might expect a slightly weaker signal in Eastern Europe.
 
R. Barr, D. Llanwyn Jones, C.J. Rodger: ELF and VLF radio waves
Journal of Atmospheric and Solar-Terrestrial Physics 62 (2000) 1689-1718
http://nova.stanford.edu/~vlf/IHY_Test/Tutorials/SubionosphericVLFPropagation/Papers/Barr_2000.pdf
is an excellent survey of VLF and ELF phenomena, even featuring a spectrogram of an Hell-mode transmission, induced by the Tromso ionospheric heater in 1982.  
 
Stanford VLF-group's directory
can be browsed for a wealth of interesting information.
 
Best 73,
Markus (DF6NM)

Grazie mille Marco.
 
I knew about the Trond infos for a long time. The purpose of my question was to try to identify 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 military system !)

300 amps for the ZEVS antenna current ??  Where does this value come from, please ?

The info comes from Trond Jacobsen researches:
