Re: To limit the messages
Hi Jiya, this might sound a bit stupid, but: Don't run you flow graph in GRC. Instead, start it from a separate terminal after clicking the "generate" button in GRC.

PDU vector format and Data controlling
Hi GNU Radio Community, I tried to implement a small transmitter section with random source with min=0 and max=2 with repeat -yes by setting samp rate as 32k and convolution encoder ,constellation modulator in the end section ,tried to connect the stream to PDU conversion to calculate the time taken and i have used message debug to it but it is printing n number of times and PYTHON IS NOT RESPONDING and after all i need to restart again. Any solution to regulate the data stream generation so that i can restrict data printing in the message debug. Need more clarification regarding the PDU VECTORS i generated 0,1 continuously for 10 samples but the PDU vector( 01 :00 00 00 00 00 00 01 00 ) contents printed in the output are not able to decode . Thanks in Advance
Re: PDU vector format and Data controlling
Hi Jiya, no offense, but could you just share your flow graph? That would makes *much* easier to work with!

Re: S-band BPSK
Can you share your flow diagram in the image format?
