Re: [Discuss-gnuradio] Install gnu radio on to ubuntu linux 9.04 (Jaunty)
Dear Johnathan and Alexandru Csete, Because there are many errors so I reinstall fresh ubuntu linux 9.04 (Jaunty) again. Then I installed gnu radio following instruction from http://gnuradio.org/redmine/wiki/gnuradio/DebianPackages. 1. Firstly I open Synaptic Package Manager. Then click *S*etting -- *R*epositories -- Third-Party Software -- Add 2. Then in APT line, I insert = deb http://gnuradio.org/ubuntu stable main 3. And I repeat and insert = deb-src http://gnuradio.org/ubuntu stable main However, after waiting several minutes, it come up errors (below). And I repeat several times, but the error still come up. So what is the mistake of my installation? Thank you Makmur This is the errors: W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty/Release.gpg Could not connect to au.archive.ubuntu.com:80 http://au.archive.ubuntu.com/(91.189.88.46), connection timed out [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty/main/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty/restricted/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty/universe/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty/multiverse/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty-updates/Release.gpg Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty-updates/main/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty-updates/restricted/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty-updates/universe/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/jaunty-updates/multiverse/i18n/Translation-en_AU.bz2 Unable to connect to au.archive.ubuntu.com http: [IP: 91.189.88.46 80] W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/Release.gpg Could not connect to security.ubuntu.com:80 http://security.ubuntu.com/(91.189.88.37), connection timed out W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/main/i18n/Translation-en_AU.bz2 Unable to connect to security.ubuntu.com http: W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/restricted/i18n/Translation-en_AU.bz2 Unable to connect to security.ubuntu.com http: W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/universe/i18n/Translation-en_AU.bz2 Unable to connect to security.ubuntu.com http: W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/multiverse/i18n/Translation-en_AU.bz2 Unable to connect to security.ubuntu.com http: W: Failed to fetch http://gnuradio.org/ubuntu/dists/stable/Release.gpg Could not connect to gnuradio.org:80 http://gnuradio.org/ (68.169.43.17), connection timed out W: Failed to fetch http://gnuradio.org/ubuntu/dists/stable/main/i18n/Translation-en_AU.bz2 Unable to connect to gnuradio.org http: W: Some index files failed to download, they have been ignored, or old ones used instead. 2010/1/26 Johnathan Corgan jcor...@corganenterprises.com On Sun, Jan 24, 2010 at 20:48, Makmur Hidayat makm...@gmail.com wrote: As far as I know that after installation then the package installed can be found in /usr/local/lib/python2.6/site-packages.

Re: [Discuss-gnuradio] GRC: sending IQ samples of square is resulting with lot of noise.
Thank you Jason, I could able to see the exact waveform of the samples from One USRP2 to another USRP2. But i found the scaling of the amplitude when I see from usrp2_fft.py and attaching a Scope Sink (like oscilloscope scope sink), there is much variance, which usrp2_fft.py is showing much amplified scale, but the real one of Scope Sink in the GRC is showing very very low amplitude factor, Is there any understanding is required here? And if i want to get some amplified result what to be done? best regards, srinivas.

I have generated the above I believe this is the maximum output power for the USRP2, and your are likely seeing distortions from the non-linearity of the circuits involved. I'm not sure what the linear range is for your daughterboards, but try turning it down to +/- 0.3 and see what happens. Also, make sure that your decimation/interpolation factors are correct. That is, if the DAC and ADC are operating at different sample rates, you have to adjust your int/dec factors or samples per symbol accordingly.

Re: [Discuss-gnuradio] tx frequency changing by clk_divider
Hi Johnathan, I'm doing something similar as you did in gr-sounder project, sending a code modulated as BPSK with the suppplied center frequency, but different code (which contains 1 and -1 also), and bandwith for the code, which is 32kHz instead of 32MHz. I used the clk_divider block to down the frequency to 32kHz, then I monitored the signal from the antenna part on daughterboard by an oscilloscope. The waveform of the signal is a nicer sinusoid wave, but it doesn't show the phase shift for -1 part in the sequence. I'm not sure if it's clear. If not, I will post some photos of the oscilloscope, but it just a continued sine wave without any phase shift for BPSK modulation. Thank you so much!

Hello, I am installing GNURadio code from the trunk using git on a laptop running Ubuntu 8.04 and have some build problems. I follow the instruction for installing the code given in the wiki. i.e installing the required software using sudo apt-get, installing boost_1_37.

Jan 27, 2010 By Sharon Rushen, CERDEC Public Affairs FORT MONMOUTH, N.J. - U.S. Army engineers in collaboration with their Navy counterparts hope to open the gates of cognitive radio development to academia, industry and other DoD organizations by building a universal radio test-bed this year. The Communications-Electronics Research, Development and Engineering Center's Software Defined Radio lab will work with the Navy Research Lab to transfer previous development done on the Joint Tactical Radio System to the GNU Radio's open source, free software environment. Through the GNU platform which is inexpensive and universally accessible, universities, contract companies and government agencies can use a common platform to advance the state of cognitive radio software. The transition to the GNU platform will help ease collaboration efforts with other organizations who frequently opt to use 'grass-roots' hardware for programming due to the comparably high-cost and limited accessibility of JTRS radios. Additionally, the GNU platform will enable the SDR lab to conduct large lab tests and field tests, rather than having to simulate larger-scale network testing. The cost constraints associated with the JTRS radio prohibit larger-scale networking, limiting the number of radios they can test at one time, explained SDR lab team lead, Tim Leising. Through funding provided by the Office of the Secretary of Defense, Director of Defense, Research and Engineering, the SDR lab team will collaborate with the Navy Research Lab, to start building a universal GNU radio test bed this year. Once the test-bed is completed, they will work together to make it remote-accessible using the Defense Research Engineering Network to house the software platform, allowing DoD organizations and external research partners to test their software on it from any location. CERDEC will facilitate a dial-in QA session for media participants to interact with leading U.S. Army researchers involved in developing the GNU test-bed. To participate in the media round table, contact CERDEC Public Affairs: (732) 427-1926. The Communications-Electronics Research, Development and Engineering Center (CERDEC) is one of the research and development centers under the U.S. Army's Research, Development and Engineering Command (RDECOM).

Re: [Discuss-gnuradio] Unable to tune Tx or Rx with XCVR2450 on USRP2
The -f argument to usrp2_fft.py is the frequency. By putting -f 1000
you are telling the system to try to tune the xcvr2450 to 1 kHz. The
specified range is 2.4-2.5 GHz and 4.9 to 5.9 GHz. 1 kHz is WAY outside
of that range. I would suggest you try something like:
usrp2_fft.py -f 5.7G

usrp2_fft.py or usrp_siggen.py) working? I can't even get those to work.
I tried usrp_siggen.py in verbose this morning and noticed again it was
unable to set the Tx frequency. Also, I think the error I had mentioned
above re usrp2_fft.py would be because the rx frequency couldn't be set.
I have tried two of the daughtercards on one USRP2, and one of those two
cards on the other USRP2, and still can't get it to set, though it
worked fine using the same code for the BasicTx and BasicRx.

Re: [Discuss-gnuradio] Unable to tune Tx or Rx with XCVR2450 on USRP2
Ya..i know...but if i put a legal value..its saying cannot receive on
channel 0..its strainge..but dont know what is happening...
can somebody please help...
its happening with all the example programs...I have also now modified quite
a few example scripts which are for usrp older version to work with
usrp2..but for them also..its giving the same errors...though they use to
work with the older usrp...

Hi Matt
I have tried usrp2_fft.py -f 2.4G and also usrp2_fft.py -f 5.7G as you

I only recently received my USRP2s and XCVR2450s, which were shipped at

This partially fixed the problem, in the sense that samples are now

says channel 0 not receiving. However, it still fails to set the
frequency of the receiver. Also, when I run usrp_siggen.py, I still get

RE: [Discuss-gnuradio] Unable to tune Tx or Rx with XCVR2450 on USRP2
Hi Josh The xcvr has a high band and a low band, which means there is a gap in the tunable frequency range for the xcvr. Therefore, the auto-calculated mid-point frequency is an invalid frequency for the xcvr. Pick a frequency in the high band or low band range: #define LB_FREQ_MIN U2_DOUBLE_TO_FXPT_FREQ(2.3e9) #define LB_FREQ_MAX U2_DOUBLE_TO_FXPT_FREQ(2.6e9) #define HB_FREQ_MIN U2_DOUBLE_TO_FXPT_FREQ(4.8e9) #define HB_FREQ_MAX U2_DOUBLE_TO_FXPT_FREQ(6.1e9) Thanks - I will keep that in mind when using usrp_siggen.py in future. However, I have tried 2.4G with the source code from my original post (relevant code snippet for Tx tuning just below this paragraph, for which successTx is 0 and all frequency properties in TxTuneResult are 0), and also with usrp2_fft.py -f 2.4G, after burning the latest images. I still face the same problem that neither the Tx nor the Rx will tune. /* try tuning Tx to a test frequency */ double Fc = 24.0; usrp2::tune_result TxTuneResult; bool successTx = device-set_tx_center_freq(Fc,TxTuneResult); ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] Unable to tune Tx or Rx with XCVR2450 on USRP2
It could be failing to lock. You may want to watch the debug port on the usrp2. If the lock detect is failing, it will print out on the serial console. attach a 3.3v level serial port On 01/28/2010 10:09 PM, Ian Holland wrote: Hi Josh The xcvr has a high band and a low band, which means there is a gap in the tunable frequency range for the xcvr.

Hey Ian,
How did the problem get fixed? I mean what frequency you are setting with
the -f option?

Manav

This partially fixed the problem, in the sense that samples are now
displayed on the fft window when running usrp2_fft.py, and it no longer
says channel 0 not receiving. However, it still fails to set the
frequency of the receiver. Also, when I run usrp_siggen.py, I still get
the same problem that the Tx frequency can't be set. In verbose mode,
the output of usrp_siggen.py is as below. Any ideas on what else could
be wrong?
Regards
Ian.
USRP interpolation rate: 16
USRP IF bandwidth: 6.25MHz
Set TX gain to: 15.0
Using auto-calculated mid-point frequency
Failed to set freq.

Your firmware and fpga images on the sd card are probably out of sync.
You can find images here: http://gnuradio.org/releases/usrp2-bin/trunk/
and here are instructions on how to burn:

Hi Matt
I have tried usrp2_fft.py -f 2.4G and also usrp2_fft.py -f 5.7G as you
suggest below. In both cases, the fft window opens but no trace is
displayed, and I see the following output in the terminal:
usrp2: channel 0 not receiving
usrp2::rx_sample() failed
I only recently received my USRP2s and XCVR2450s, which were shipped
at
the end of December. Are there any known issues with the firmware on
the
SD cards at this time, or do you have any other idea why I can't seem
to
tune frequencies on these cards?
Thanks
Ian.

The -f argument to usrp2_fft.py is the frequency. By putting -f
1000
you are telling the system to try to tune the xcvr2450 to 1 kHz. The
specified range is 2.4-2.5 GHz and 4.9 to 5.9 GHz. 1 kHz is WAY
outside
of that range. I would suggest you try something like:
usrp2_fft.py -f 5.7G

Actually no...its always returning false...
when I use usrp2_fft.py with -f 1000 then output does come but still
it
is unable to set the initial frequency though it did receive.
I am still trying to figure out the problem...
