Tobias,
I've made a short test using the new version and the old simultaneously,
using the same audio input. There are no decodes at all in the new
version, with or without the SpecLab NB enabled. The waterfal looks
equal in both versions...
Does it work on your side?

Hi Stefan/LF !
Information on the SVN-server says, that there was a noise blanker
added.
Thanks for all the infos.
Finally :-) During the time he developed WSPR-15 we were in regular
email contact. To that time i made some tests with DF6NM's slow WSPR
version, tests with 4X1RF and GW0EZY and others. We found that the
SpecLab noise blanker in front of the WSPR input (using VAC) made a
S/N improvement of at least 2 dB. Obviously he anyway didn't include
such a tool (which is much more useful on LF/MF as on the HF bands i
think) in the previous versions.
Now the question is if the new intenal NB is more efficient than an
external SpecLab NB. One could do a test running 4 WSPR-x instances,
the old one, with and without a SpecLab NB and then the new one, with
and without a SpecLab NB... If the new one without a SpecLab NB
performs best, then this would be really an improvement over the older
version! If i can find the time i will do such a test at night.
