Thanks Steve and Bill for your prompt replies. This setting is one of the features of WSJT-X that I tweaked when I first used it and had long since forgotten about. Is there a way to measure decode times accurately? Just doing it by 'eye', I get these approximate figures )on the same .wav as before): 1.8.0-rc1 fast/normal/deep 0.2s/0.5s/0.7s 1.8.0-rc2-r7924 fast/normal/deep 0.2s/0.5s/0.7s 1.7.1-devel-r7944 fast/normal/deep 0.4s/0.8s/2.5s 73, Richard G4DYA ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
