Hello Daniel, I've been experimenting with the RS decoder in gr-satellites for the past few weeks and I've had some great results, thanks for pointing me in that direction. However, I'm still running into a few problems -- some directly involve gr-satellites and some are just about basic taggi

Ah, by the way, could you try the following dirty hack: 1. Copy the generated update_period.py file. 2. Find the place where self.blocks_throttle_0 = ... is done 3. after that, insert self.blocks_throttle_0.set_max_noutput_items(int(samp_rate/100)) and report whether that works? Best regards, M

Hi Marcus, Thanks for your answer. Please, check out this flowgraph. Shouldn't the Time Sink update its graph content every second in this configuration? [image: image.png] https://gist.github.com/marcinsztajn/224ced2e1b3921aa97ef28978c1b8426 BR, Marcin śr., 29 gru 2021 o 19:27 Marcus Müller na
