Hi Mubashira,
When I was writing the https://wiki.gnuradio.org/index.php?title=Packet_Communications tutorial, I remember having some problems with the gr-digital/packet examples. If you haven't already done so, you might like to look at that tutorial. I don't have my GR 3.8 computer up right now, but when I get back to it, I will look into those examples again. Best wishes, --- Barry Duggan KV4FV https://github.com/duggabe On Tue, 25 Jan 2022 06:51:56 +0000 (UTC), Mobi Zaman wrote: Hi, I am trying to run this flowgraph in gr-digital/packet examples on GNU Radio 3.8. When I run the flowgraph, the output shows a flat line (amplitude is a constant zero). I do not have enough understanding of these blocks yet to determine what is the problem here. Can anyone please mention how the output can be corrected? Regards,Mubashira Zaman
