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.
