Hi Matija,
I'm sorry but we are still not 100% sure how this might have happened but
the team is working on figuring it out.
In the meantime you might want to rewrite the value in the EEPROM.
In order to do that you need to do the following:
1.) comment the hw_rev check in x300_impl.cpp (located
Hi Martin, Marcus,
I am using a N200 + WBX.
Gain set on the USRP is equal to 5 dB.
Changing the power of the input signal does not change anything. Moreover
the output of the signal generator is sent (via a 2way power divider) to a
spectrum analyzer and the input signal is ok.
I made some other t
Hi,
i want to use an external usb sound device. It works without any
problems when playing back music. I dont know how the audio sink block
or gnuradio works with this extern sound device. Howto tell gnuradio to
read all possible sample rate values and use this device ?

Hi Luca,
just to get a feeling

In your received signal, there seem to be high-power peaks. How large is
the digital signal amplitude during these?
Since the mirrored peak seems to be just a bit weaker, my suspicion
still is too
Hi Andy,
assuming a modern linux.
In the Audio sink/source, you can enter the device name; potential names
can be found by running
aplay -L
GNU Radio doesn't know anything about the supported rates of sound
cards; you will need to try that one out beforehand. As far as I know,

Hi Marcus
My soundcard support sample rates up to 192khz. So iam asking me how
this sample rate could be set manual or the automatic selected
samplerate could be veryfied. In the audio sink block max. 48khz could
be set.
What device name are you using? If you happen to use "" or "default",
it's
can you try any of the hw names?
Other than that, this might just be ALSA strangeness; as far as I have
had a glimpse at the code, about 2 years back, the audio blocks don't do
anything "special".

Try running uhd_cal_rx_iq_balance and see if that helps.

Hi all,
I want to transmit the data between two USRP's and make them communicate
with each other. But I guess the packets are not being received
properly.
My USRP daughterboard model is XCVR2450. When I am running
./benchmark_tx.py -f 2.435G, it is starting to transmit the packets but
a small error
Dear,
I installed GNU radio from build_gnuradio script successful.
Then I tried a simple FM receiver and I got this warning :
UHD Warning:
Could not locate USRP1 firmware. Please run:
"/usr/local/lib/uhd/utils/uhd_images_downloader.py"
Then as it said, I tried to run that .py file and go

I have produced a complementary demonstration of the polyphase channel
synthesizer and a tool for generating test signal. As before, it was
developed using the a very recent gnuradio release (3.7.8rc1) so older
installations may be unable to load the grc file. Will publish
shortly...
As a meta poi
Here it is; many thanks to N8UR for the feedback and corrections ...

The synthesizer doesn't really look like much when it's running, but
you can see on the waterfall where the "extra" channel is used - it's
having an existen
Dear all,
I would like to do some simple frequency hopping over my USRP (x300 with
UBX-160 daugherboard). To that end I wish to use the following tags:
- tx_len (defined in the length-tag field of the USRP sink). This
(naturally) gives the length of a burst
-tx_freq -> used to change the centre
