[Discuss-gnuradio] Schedule for GNU Radio 3.7.9 release - abi-compliance-checker

2015-12-01 Thread Maitland Bottoms
Hi, I played a bit with the abi-compliance-checker which resulted in the attached patch. Alas, it complained a bit on gr-uhd - perhaps unable to figure out uhd from the Ettus UHD headers and uhd from gnuradio headers. So I punted, and told abi-compliance-checker to skip include/gnuradio/uhd

Re: [Discuss-gnuradio] HELP!!! USRPN210+GNURADIO

2015-12-01 Thread Harold Daniel Moreno Urbina
Like one year ago I was testing with USRP N210 with the blocks attached to this message. Note that one is for transmission and the other one for reception. I am lucky and I got 2 USRP N210, so I was able to send a tone (one sin function or the add of two sin functions) and receive it correctly.

hello when i set the uhd_sink or uhd_source samp rate to 10M i got that The hardware does not support the requested TX sample rate: Target sample rate:10.00 MSps Actual sample rate: 8.00 MSps then i set it to other value,some of them is ok,some not, i know that the max samp rate of

Hi Ekko, The sample rate has to be some fraction of the clock rate divided by an integer. The clock rate on the E310 defaults to 32MHz I believe, so 32MHz divided by 4 gives you 8 Msps. The system will get you as close as it can to the desired sample rate. You can set the clock rate to something

[Discuss-gnuradio] HELP!!! USRPN210+GNURADIO

2015-12-01 Thread mohamid92
Hello everybody I just start working on USRP with Gnu radio. In last two weeks I was looking for tutorial to test my USRP without programming any blocks. The only tutorial I found is an FM receiver, but unfortunately frequency range of USRPN210 is way much bigger than FM frequencies (400MHZ-to

Hi Sylvain, Sorry for reviving a relatively old issue. I see that you mentioned some tweaking to be done on the fft block when the signal are weak. I'm currently working on an application using this RFNoc blocks and I'm having that problem: I'm calculating the power received at my radio and below
