100 stations TX does not represent 100 simultaneous transmissions. It represents 100 unique Stations decoded over a 10 minute period. This number is based on reports generate world-wide and does not represent the level of activity to be expected at any receiving location. It does not necessarily indicate a crowded band. Propagation, Band and time of the day will greatly influence the level of activity to be expected by any particular receiving station. Your waterfall image, while it shows a lot of activity, does not indicated a crowded band, IMO. de Laurie VK3AMA ------------------------------------------------------------------------------ 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
