Peter,
yes I was also wondering whether it was really
me but now it's sure. I think I did have some samplerate tracking issues
around 11 UT, but it looks good again now. Interestingly but perhaps unrelated,
DHO went off air for a minute at 11:18.
In the past we have observed that the diurnal
propagatipon pattern depends on the phase between groundwave and ionospheric
components, and thus on the distance between TX and RX. So it may well be
different between you and Uwe, versus you and myself. Unfortunately I won't be able to transmit contiuously throughout day and
night, and will have to go off air around 13
UT today.
Best 73, and thanks again,
Markus (DF6NM)

8270.020 Hz
Hello Markus, VLF
At first I was quite sure,
but later in the morning I started to doubt whether I did receive DF6NM.
Meanwhile, in the afternoon I really see the
trail of DF6NM appear in
the spectrogram.
As you can see in the traces of DJ8WX (in my grabber) the
propagation is not good during daylight between us.
I hope you are able to stay on air for a
while.
73s Peter

Great, it seems to work! DJ8WX had
apparently interrupted his carrier for an hour but has come back. To
my surprise, I seem to be making it to Appingedam as well
Thanks to Lubos and Peter for monitoring
and running your excellent online grabbers, and to Uwe for motivation and
company!

Hello Markus, VLF!
I am looking forward to see your signal on
my grabber. It would be fine to see both signals, from Uwe and you,
together.
73!
Lubos
This afternoon I have
resonated the venerable seven-bucket VLF coil to my home
antenna on 8.27 kHz, and I'm currently running a test transmission on
8270.020 Hz. Assuming appropriate weather conditions (ie no wind and rain,
but cold and grey so that the neighbours won't want to enjoy their gardens and
complain about the tone), I intend to join Uwe 5 mHz below his
carrier, for a couple of hours starting sometime around 8 UT tomorrow. The
signal will be weak (10 uW ERP) but I'm hoping to leave a trace in Lubos'
grabber window.
Best 73,
Markus (DF6NM)
