Dear Aruna,
please compare the bandwidth that you'll need to receive 802.11n with
the bandwidth that your PLUTO can deliver to your computer.
Best regards,

Hi, coolest SDR community since Fourier solved his first integral,
so, it's come to the point that I'd like to merge the next branch into
the master branch.
That means we're getting closer to 3.8 – yay!
But it also means that I'll have to freeze the PR pipeline for until
that merge is done - meh.
Have you first registered the "clock" message port? This looks like
you're trying to set a handler for a message port that doesn't exist.
Also, when asking for help, it's usually very helpful to have your
*exact* code somewhere, not a reference to code that is /similar/.
Best regards,
Marcus

Your GNU Radio was built without Thrift support.
You need to uninstall your GNU Radio, go back to the CMake step in
building it, and make sure all the requirements are met: in this case,
PyThrift and thrift, need to be installed probably. The CMake output
will tell you exactly what is missing.

Hi Martin,
internally, the RTL dongles are fast enough to capture full DVB-T (not
-T2) channels, and demodulate, and decode them, and deliver the video
stream to the host. However, RTL-SDR can't use that mode - it uses a
"bypass the whole Digital TV specific stuff" mode and directly passes

Hi Mark,
well, in the end, as a maintainer, I do really think that GNU Radio
could do better at being easy to integrate in applications that aren't
foremost about being GNU Radio applications, but something else. As
said, it's absolutely possible to just generate a flow graph with GRC
once and int
Nothing; seemingly I messed up when merging a PR. Will fix that
instantly!
Thanks!

Hi Andres,
just had a short look: doesn't NTSC use a nearly 6 MHz bandwidth?
Best regards,

Hi all,
GSoC is over and it's time to summarize what has happened over the summer! The
most important part first: Both students passed the final evaluations!
Congratulations, Swapnil and Luca!
I think I can speak for the other mentors, too, when I say that they didn't
just pass, but really e
Hi engineerpcp,
I'm not aware of any problems with that block. The most likely
explanation is that you have conflicting installations of GRC block
files. Please make sure that GRC doesn't try to load GRC blocks from a
path you have older versions of GNU Radio installed in. GRC prints the
block pat
Hi Murray,
not an expert on the Altera side of things, but generally:
You'll need a simulator as VHDL simply isn't C-calling convention
callable code ;)
So, there's different approaches to that, but as far as I know, noone
has yet written an adapter that somehow (magically?) pipes data into

Hi Mark,
don't think I can contribute much to your understanding of the hints,
since that seems to be correct and comprehensive:
The gui hint is (row,column, row span, column span). This is pretty
much a direct delegation of how the Qt Grid Layout [1,2] works.
So, Qt just looks for the highest ro
Hi Martin,
arguing that this is unrelated to osmocom, but relevant to GNU Radio:
I'm CC'ing the discuss-gnuradio mailing list [1]; I'll recommend
following up there (and taking osmocom-sdr out of CC: when doing that),
unless someone else sees an argument for keeping this discussion here.
So, GNU
