Hi Nicolas,

The distance is 797km, http://no.nonsense.ee/qthmap/?qth=3DJN18IP&from=3Djn68r= b

This=20 is a VERY impressing and remarkable RX result! His signal seemed to be= rather=20 low today, compared to monday but you've got an excellent reception in= 4.5=20 mHz. Congrats to you and of course Ossi! The first OE-F contact on VLF= it=20 seems :-)

Your loop design becomes more and more interesting for= me!=20 Would be interesting to compare it to an active E field antenna at the= same=20 location.
What do you estimate is the SNR loss if you would choose th= e=20 quietest location where the loop can be fixed arranged?

This show= s that=20 VLF reception in the range above 500 km and even QSOs may be done by fix= ed=20 antennas! A good VLF day!

73, Stefan/DK7FC

Hello Dreamers, Ossi attached my screen capture of your VLF=20 transmission this afternoon.
In portable for a noise-free environment, locator JN18IP.

hallo niclas
tnx fer your report ,
so in this time i transmiting only with the marconi
220 ma smal signal fore  testing the conds ,
weather here very poor stormy and snowfall ,
wet wx conds not good fore high voltage on the anttena,
and no ballon by strong wind ,
so by the next activity i gife a info on the reflector,
you can see the smal signal on my grabber here 10 km from my station, peak=
ing=20
only to -80 db ,
normaly by ballon 100m high its on -70 db ,
