Any chance you can share the code? I will try to get some approval here to release, however it may be a bit of time before I am allowed to do that unfortunately. Try and remove the .xml-file output from the test and run again. Maybe it's a problem of persistence? I tried this just now, stil

Thank you. I have taken out the throttle block and add an AGC block at the receiver. To proceed with the synchronization, should I use a Constellation Receiver block or a Polyphase Clock Sync block ? Kind regards, Azza -- View this message in context: http://gnuradio.4.n7.nabble.com/Error-rat

Hello again, Marcus, you are right, my syntax is not any more correct but there is backwards compatibility. I initiated error on my own and everything works fine, so I would say there should be rather something more serious. On Tue, Apr 15, 2014 at 4:31 PM, Marcus Müller wrote: > -BEGIN PG
