The bandwidth of DVB-T is 8 MHz (or 7 MHz for VHF). You can't capture
that much bandwidth with an RTL-SDR. The required sample rate is
(800.0 * 8) / 7 = 9.14286 Msps for an 8 MHz channel, or (800.0 *
7) / 7 = 8 Msps for a 7 MHz channel.
You need an SDR that can handle these sample
I am attempting to read samples of an off-air DVB-T transport stream into
an IQ file for offline analysis but can't get it to work at all.
I can run the dvbt_rx_8k.grc example which reads the adv16.cfile IQ TS
file produced by Ron Economos, displays the FFT and 16 QAM constellation

I'm having trouble with a gnuradio install. It built successfully, but I
can't import gnuradio in python. I believe it is because I'm using anaconda

I'm using pybombs to install gnuradio 3.7.13.5 onto ubuntu 18.04. Pybombs
seems to be unable to install dependencies anymore. Each time I run

There are installers for windows:

That will come with RTL-SDR drivers, etc. Just run the "run_grc.bat" from
the /bin directory (or use the installed shortcuts)

Hi Hans, hi Glen and Barry and everyone in this thread,
I had a longish answer written out to this, addressing all the things
that I agreed to, and explaining quite a fair bit of where you're
wrong, but I decided to scrap it and reduce it to three bullet points:

Hi Ivan,
I would not recommend to use the 'master' branch at this time with the E310
release-4 SDK. UHD 3.15.x.x bumps the deps from what is used in the
release-4 SDK.
I would recommend to try using the version 3.14.1.1, which is the latest
stable release (note, you'll need to install python-six
Hi David,
This sounds like it might be a bug with the E320. Can you email us at
supp...@ettus.com and we can debug the issue through that channel?

Hi Barry,
If you're just getting started with mediawiki/markdown, it would probably
be best to join the GNU Radio slack channel and coordinate within the #docs
channel, you can register here [0] and then login here[1]

Hi Hans, Marcus, and others,
I totally agree with Hans: "Because I never succeed with pyBOMBS and the
distro packages are outdated." I have tried using PyBOMBS on my Mac and
on my Raspberry Pi 3B+, and neither one worked. As far as distro
packages, they are all way behind.

Laura,
are you getting any error messages you can post?

You've used linux for 20 years and it took you half a day to figure
out you need to call

I know I'm going to ruffle some feathers, but my intentions are noble,

un-Linux
Hi Hans,
I'm happy that Kyeong fixed that page.
But honestly, you shouldn't *need* to compile GNU Radio from source,
unless you want a recent development version of it. What's the reason
you're doing that?
Best regards,
Marcus

To expand on that: Libusrp isn't compatible to any modern USRP, and if
you've got code from that era: Reimplement it in modern GNU Radio,
mostly. You can't hope to copy much of that, because the last version
of GNU Radio to contain libusrp was I think 3.4.2, and that's been
obsolete since the
