Hi Alan,
Yes, that's a good explaination. I noticed that first decodes at TF3HZ
happend quite late last night. Reports on high distances (> 1000 km)
were rare, as if there would be high QRN!
73, Stefan
PS: I just checked the WSPR database. You can see there were only a few
decodes at low SNR last night. The day before, there were much more
decodes, sometimes with much better SNR! I was running 1 transmission
in 20 minutes, last night and the night before.

Hi
Fausto, Stefan, this is an interesting observation, but are signals
really stronger? We are in the middle of a period of geomagnetic
activity with the Dst down around -100nT and likely to go a bit lower.
This suggests that ionospheric signals should be attenuated. It may not
have as much effect on one hop nightime signals (<200km) as on
longer path signals, but I wonder if the lack of QRN is due to "DX
noise" being attenuated too?

Hi Fausto,
Yes i saw there was nearly "no QRN". The noise background at night was
as high as in daylight. Maybe this means that (my) the noise background
is man made?

Hi all,
good propagation yesterday evening on MF.
I have listen and seen on the waterfall my CW signal on 4X web sdr
around sunset.
The signals were barely audible, but it is a sign that the season
approaching.
