Hi, Please find the code here https://github.com/saki92/oqpsk-sync-block . I am trying to build a clock sync block for oqpsk with pfb_clock_sync as reference. It does not show any error message from Python or C++. The flowgraph runs for less than a second and stops. Some times I get a return code -11.
