Looking at the WSPR database, F6CNI is decoding me consistently in the 0dB S/N region.
At 391km this can't be realistic, and most likely comes from using a narrow filter - sub 200Hz - before feeding audio to the decoding software. The WSPR software does need a flat audio response in the 1400 - 1600Hz range, and preferably over the complete SSB bandwidth.
