Thank you for pointing me to WSJT-X v1.7.0-devel, it actually performs better than my old WSPR-X v0.9 r3058, especially when strong and weak signals are present in the same time slot! It also shows a 2 dB better SNR (sometimes) but i don't (still) know if it is 2 dB more sensitive. Also it decodes faster.
I will use it from now on.

Why does the program not save the band? After a restart it always starts on 2m... But that's a minor problem...
I will see if it runs for weeks without crashing, an important parameter!

How is it possible to run 2 or multiple instances? Do i need 2 installations?

I'm still using WSPR-X v0.0 r3058 here. Newer versions performed worse for some reasons. This version does not produce SNRs better than +15 dB if i remember correctly.

Another thing may be that someone could use e.g. a 250 Hz wide filter instead of the reference filter bandwidth of 2500 Hz (SSB), which then produces wrong ("improved") reports.

If I listen my signal with my RX antenna 5 meters far from TX antenna my SNR is maximum +13 db, also for IZ0GIF that is about 4 km far from me.
Probably Andy has an exceptional receiving system but +17 to more than 1000 km is a great SNR I thing, HI.

After some minute great reports again:
