Hello the group, sorry for my kind of self-deception - problem solved!
I am using a rather long batch file to set parameters, start WSJT-X and other utilities. Copied over the 2.01 batch into a 2.1 batch file and made one small typo. Did not change anything for the operation of the 2.1 WSJT-X, except that mode setting (bug) hidden in the back- ground. 73 de Wolfgang OE1MWW ---------- _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
