interesting Information, because : Soundcard has an indicator LED, LED ON means, power ok. Flashing means data is being read from the soundcard. And the LED is flashing(all the time)even when waterfall and decode stopped. -> wsjtx reads data from soundcard??? but does not pass data to jt9 ??? No Error Messages are generated in wsjtx. Behavior is the same like I'm pulling USB cord while wsjtx is running-> no message is generated and decode and waterfall is stopped. 73 Frank DB5FP ------------------------------------------------------------------------------ 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
