Hi Markus,

>This is truly amazing, WSJT-X v1.7.0 can decode two stations 
>on the same QRG:

There seems to be a certain limit somewhere above 13dB for this amazing 
capability (or miracle if one prefers)
regarding the difference in signal strength between two stations on the same 
frequency.
At my qth DK6NI was around -16 to -17dB SNR shortly before 20:34 and DH5RAE 
came in with +17dB SNR at 20:34.
Only DH5RAE was decoded.
LA8AV and PA0MLC had a difference of 7dB in SNR and where decoded here on the 
same frequency as well.
It would be interesting to run a test under defined conditions to find out 
where the limit is.
