Hello VLF friends,

This morning i looked on the EA5DOM VLF grabber and saw much better traces of the carrier on 17.4701 kHz.
https://ea5dom.ure.es/grabber/index.html

I find this is a valid one-way contact or carrier detection and i think it is the first time that this was done by amateurs between DL and EA.
A distance of 1393 km, http://k7fry.com/grid/?qth=IM98XN&from=jn49ik00wd

It looks like there is some QSB on that path, higher than observed a similar distance at 8270 Hz.
We can now think about improvements and about a first message attempt...

73, Stefan
