Hi all, as the GIF plot got through the reflector, I will push my luck with
another one. Thanks again to Brian CT1DRP for his efforts in systematically
logging DCF39.

I did not say before, but the horizontal axis is 24 hours starting 0600z ,
and the legend for the plots is the date of the the extreme right-hand side
i.e 12/11 finishes at  0600z on the 12th Nov.
The X-axis only shows the first digit of the hours time (a function of the
number of points on the plot) so you will have to 'count them up'. The black
line is again an average calculated for about 15 'quiet' days in Spetember,
so the normal sunrise / sunset times do not align with the weekend plot.
Look only at the averge daytime and night-time levels.
Sunday (blue) was if anything a better day than Saturday as the enhancement
lasted longer. It is only a pity as Rich said that the static was so high.
Once again night-time conditions do not look too bad, but bear in mind this
(one hop path) does not relate well to two-hop trans-Atlantic paths where
the absorbtion with be 10 to 20dB greater.
