Hi VLF

Congratulations Stefan and thank you all for the good information exch= anges in the reflector

It is all the effort at your side Stefan. I still didn't do the homewo= rk to decrease the local QRM, which is
quite high as you can see in the 25KHz spectrogram. There is a very na= sty noise which appeared just
this last couple of days and affects exactly 17470Hz. It is random and= runs for a couple hours. Can be seen
as vertical noise lines in the lower spectrograms and is very noticeab= le in the 47uH spectrogram

It is my first detection of Ham activity under LF so far. And there is= a lot to improve to get same results
at 8270Hz. A new Rx setup in a different (hopefully cleaner) QTH is in= the "To Do" list ;-)

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=3DIM98XN&from=3Djn49ik00wd



It looks like there is some QSB on that path, higher than observed a simila=
r distance at 8270 Hz.

We can now think about improvements and about a first message attempt...


73, Stefan
