I also tried the amplitude and power normalisation
trick but that didn't improve the result either.
I thought a bit about noise cancelling techniques. You recently said
that you are using different filter/blanker settings for daytime and
nighttime signals.
Since you are programming all the software you are using (ufb!, i wish i
could do it too :-) ), would it be useful to determine the optimal
filter/blanker settings from the signal appearing during the analysis? I
mean, can you analyse e.g. QRN bursts (time domain, checking rise time,
and peak above average) and then apply an optimal, individual filter
which already includes the idea of the power normalisation trick? :-)
