According to the "SmartSDR for Windows" change log, beginning with the version 2.2.7 alpha software, the Wideband Noise Blanker (WNB) "now works properly" for the Flex-6400M. Did this (enhanced?) WNB functionality make it into the the latest official release, v2.2.8 software? I am running v2.2.8 from the front panel of a 6400M but still see no impact whatsoever with pulse-type noise. Have others in this forum seen any improvement when running WNB?
