Hi Stefan and Alan,
Are two nights that the QRN is low.
Fortunately I live in an area where the man made noise is very low and, on
25 and 26 night
I saw an increase of noise propagated by an average of 15 dB relative to the
background noise during the day.
On the evening of 25 was good propagation to the north, DL6TY heard me 589
even though I heard his signal
to the limit and we did no QSO.
Last night my signal on the grabber and remote SDR to the north was strong
but not as the previous night, but
I jumped on my chair when I saw my signal on the 4X remote SDR and, very
weakly, I heard also aurally my CW signal.
This occurred shortly after sunset and for a few minutes.
That the propagation has a peak around sunset as the higher band (160 and
80m) I had already noticed days ago:

in this case the signal has increased around sunset in the area of the two
reverse beacons.
I will try further in the next evening to see if the event will be repeated.
73, Fausto IK4NMF

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.
