Do you have the latest gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk I have the SVN Version 2009-Jan-28. Aha, I believe that I added the set_sample_rate callback recently (possibly in February). svn up! Further on everytimen i open my *.grc file, the grc deletes the manually inserted class-method, set_sample_rate so there must be a Problem. When you generate or run a flow graph in grc, the generated flow graph is always overwritten. Also, I am concerned that the gl fftsink aborted/segfaulted.

I do not understand why you have the problem? Do you have the latest gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk I have the SVN Version 2009-Jan-28. It was this changeset on jan 28th http://gnuradio.org/trac/changeset/10327 Make sure the files are installed. good luck -josh ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
