Hi Tamas, I decoded the same 6 decodes as Steve with build 7774 on Windows.
Hope this helps, ON4PB, Erik. ------------------------------ Message: 3 Date: Sun, 02 Jul 2017 13:37:21 +0000 From: Steven Franke <s.j.fra...@icloud.com> To: Joe Taylor <wsjt-devel@lists.sourceforge.net> Subject: Re: [wsjt-devel] r7775 FT8 decoding Message-ID: <d12fead4-47cd-4e5b-8181-440f82bcd...@icloud.com> Content-Type: text/plain; charset=utf-8 Hi Tamas, Your files produce the following decodes on r7775 here: ------------------------------------- 6m 130800 -7 0.9 1097 ~ EI4KF ES6DO KO27 ------------------------------------- 6m 130815 -12 0.5 1098 ~ ES6DO EI4KF -13 ------------------------------------- 6m 130830 -7 0.9 1097 ~ EI4KF ES6DO R-08 ------------------------------------- 6m 130900 -17 0.9 1097 ~ EI4KF ES6DO 73 ------------------------------------- 6m 131000 -10 0.9 857 ~ CQ I4WQH JN54 131000 -13 1.0 917 ~ CQ ES6DO KO27 As far as I can tell, all of the signals that are visible on the waterfall are decoded. I am running on OS X here. Perhaps others can try to decode your files to see if there is a problem on Windows.

The 50% decoding threshold is at about -21 dB. These results pertain to an AWGN channel (no fading) and were obtained using .wav files generated by ft8sim. Each .wav file contains 25 signals. A total of 40 such files (1000 potential decodes) was analyzed at each SNR. The ft8sim DT parameter was set to 0.5s for this simulation. > > I should note that the idealized AWGN channel simulation used for this benchmark does not reflect the type of conditions that we typically see in real life on HF or 6m.
