Hi Tamas, Your files produce the following decodes on r7775 here:
------------------------------------- 6m 130800 -7 0.9 1097 ~ EI4KF ES6DO KO27 ------------------------------------- 6m 130815 -12 0.5 1098 ~ ES6DO EI4KF -13 ------------------------------------- 6m 130830 -7 0.9 1097 ~ EI4KF ES6DO R-08 ------------------------------------- 6m 130900 -17 0.9 1097 ~ EI4KF ES6DO 73 ------------------------------------- 6m 131000 -10 0.9 857 ~ CQ I4WQH JN54 131000 -13 1.0 917 ~ CQ ES6DO KO27 As far as I can tell, all of the signals that are visible on the waterfall are decoded. I am running on OS X here. Perhaps others can try to decode your files to see if there is a problem on Windows.
