[Discuss-gnuradio] Burst Transmissions

Hi all,

This is kind of a reword of a previous question I asked yesterday. I don't think I did a good job.

I am receiving data bursts that can be separated by no transmissions (noise) for extended periods of time. I want to figure out a way to get the bursts of data into a file without the noise. I can identify the bursts and how long the bursts are in terms of bytes. I can't figure out a way to then get the burst into a file without all dead time between them. The dead time translates to large chunks of zeros in the output file.

I'm attaching a flowgraph of what allows me to identify the burst header, remove the header and claim the payload. The problem remains that along with the payload going to the file, large chunks of zeros are also making it into the file.

I would really appreciate some guidance.
