Thanks for your answer Tom. I can isolate the fault to one of my blocks: http://www.zhaw.ch/~hoim/howto_ofdm_symbol_cutter_cc.cc
This block has two inputs, both have the same rate. If I connect the input to a file with throttle and the output to a "vector_sink_c" I see that the amount of data produced by the block is not always the same. My conclusion is that my block looses data. In this block I cut data out of a stream. Hence from time to time there are rest periods between the data production. Is this a problem for gnu radio? Should I allocate more memory for this block (how can I do that)? Any help will be appreciated Thanks Michael _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
