After the succesfull experiment by Henny, I took down the
Mini Wipe antenna and re located it 4 meters more away from my house
and about one meter higer into the sky. Below a picture how it looks
today. Nice settled between the Conical Springs, well that's
what Google translate told me. After some research it better to
translate it into Conifers :-)

Again a succesfull experiment today by Henny, PA3CPM on 8270.000. Henny
wrote that the antenna current was
0.6 Amp's again. Below is his signal highlighted in the orgional
spectogram.

A succesfull experiment by Henny, PA3CPM on 8270.000. Henny
was able to make 0.6 Amp's into his 16 meter long sloper antenna.
In the spectogram below is PA3CPM his signal visible at the very right.
He was actualy on air here between ~ 07h30 and ~ 18h UTC.

DJ8WX, DF6NM and PA3CPM went QSY to 8270 Hertz because radio
now starts with 8.3kHz, and not 9kHz !

DJ8WX QRV with some tests on 8970Hz, mode CASTLE,
shift 0,002Hz.

Once upon a day in January 2013 I took a look at the VLF
grabber screen, and was surprised
that I suddenly
saw a
trace of
human civilization
:-) That signal was already 3 day's on the air without notice. Because
the frequency and accuracy is almost like a fingerprint for stations on
9 KHz, I wrote Uwe, DJ8WX if it was him. He did confirm...
Between 1 Feb ~19h30 and 2 Feb ~11h00 you can see the frequancy drifting
down- up - down and up a bit (0.03 Hz !!! :-) I did ask Uwe if it was
his or my equipment. Uwe did confirm that he saw the same pattern
localy. It was his GPS antenna that got wet and did not receive GPS
satellites anymore. That illustrates that a accurate and stable is
veryyyyyyyyyyyyyyyyyyyyyyyyy importand :-) In the 424 uHz
spectogram is stil some coherence between pixels during that unstable
frequency periode. In the 47 uHz spectogram is that cohenrence totaly
gone en is not recognizable anymore...
424 uHz, 30 January - 4 February - DJ8WX on 8970.022

238 uHz, 28 January - 4 February - DJ8WX on 8970.022

47 uHz, 15 January - 4 February - DJ8WX on 8970.022
