You need to be careful in what you interpret from this! the noise may be low because the propagation is rubbish :-))  The conditions dont necessarily support this but we have just had a minor storm Kp=5 and the Dst was depressed to -60nT.

 

I remember early on, on 136kHz when we thought that the best time for DX would be around dawn.......except it turned out that the morning and evening quiet periods were poor propagation periods as well.  You need a signal to determine S/N :-)) particularly if N is changing.

Hello Bob,

Interesting to see that the low noise today is at least "Europe wide" :-)

Perhaps even Worldwide ???

 

I wonder if you publish your spectogram's online somewhere ?

I think I did not see you in a 'grabber' list somewhere...

 

Unfortunately I don't see anything right now at 8270.014 in your spectogram.

I think to early to see first spikes :-)
