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:

https://www.dropbox.com/s/efeir8tccdztftl/08082015.JPG?dl=0

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
