Re: [Discuss-gnuradio] On the "right" approach for developing applications to be run on an E310

Thank you for your answer. I understand your position but I'm not an expert of cmake and at the moment I use the uhd library to compile my app. There is a general template or something like a procedure (step by step) to build all the directories, files and so on to cross compile an app using the

Re: [Discuss-gnuradio] Connecting two USRP B200 radios

For RX gain, you will probably need around 20-40dB. Yes, you should place the 30dB attenuator in line with your connection. You should be able to slowly increase the transmit gain until you see the signal. Double check that the correct ports on each board on in use, a green light will light up

[Discuss-gnuradio] Ettus E310 FM Radio

Hello, all. I just subscribed to the mailing list and am using an Ettus E310 USRP connected to a Ubuntu-GRC platform via LAN. Gnuradio Companion (GRC) works more efficiently this way when compared to doing an SSH -X session to the E310 and using the E310"s internal GRC. Of course the LAN has

Hello, thanx Alexandre, that's what i was looking for. So with your suggestion the line looks like this: /usr/bin/c++ -O3 -DNDEBUGCMakeFiles/test-TMS.dir/test_TMS.cc.o CMakeFiles/test-TMS.dir/qa_TMS.cc.o -o test-TMS -rdynamic /usr/local/lib64/libgnuradio-core.so -lboost_filesystem-mt

Re: [Discuss-gnuradio] Ettus E310 FM Radio

There is a stereo FM receiver in gr-rds. If you delete the RDS specific blocks in the example flow graph (gr-rds/apps/rds_rx.grc), you don't even have to compile gr-rds. https://github.com/bastibl/gr-rds Ron On 11/06/2015 11:05 AM, John B. Wood wrote: Hello, all. I just subscribed to the

How can I check/add -L and then path to the gnuradio blocks library in order to force setup to use it? Or maybe I am on th ewrong way? On Thu, Nov 5, 2015 at 6:25 PM, Nemanja Savic wrote: > Tried that already a few times and nothing. Is there any so called cash > where cmake

[Discuss-gnuradio] Connecting two USRP B200 radios

Hello everyone, i am new to the world of SDR. I currently have two USRP B200 radios. I would like to connect the Tx port of one SDR to Rx port of second SDR using a cable to visualize the transmitted bits. I am generating random bits with Ts=1/1 and 50 samples per frame. Using a rectangular

Re: [Discuss-gnuradio] Connecting two USRP B200 radios

Hi Ash, Yes, you need to use an attenuator if you are connecting the B200's directly together with a cable. I would recommend at least 30dB of attenuation, but that depends on your settings. It is recommended that you do not input more that -15 dBm into the receiver of the B200, as this can

Re: [Discuss-gnuradio] On the "right" approach for developing applications to be run on an E310

You can compile simple programs very similarly to how you normally use gcc/g++. Source the OE SDK, then call CC or CXX. The environment script exports these variables the way you would expect if you're familiar with cross compiling at all. You *could* just call arm-oe-linue-gnueabi, but you

Re: [Discuss-gnuradio] Frequency discriminator using a frequency to voltage converter

Hmm.. maybe it is. I have done it in (shudder) LabView and it's nice since noise reduces at 1/N instead of 1/sqrt(N); N is number of averages. Maybe I'll try it tonight with just discrete blocks to compare them side by side. Just something that can't be done with a normal spectrum analyzer.
