[Discuss-gnuradio] reminder: French GNURadio days -- deadline approaching

A quick reminder, for those interested to meet to discuss the latest developments related to GNURadio in France and Europe, that the deadline for submission and registration for the French GNURadio days is approaching (May 20). The web site with the program, template and registration is at https:/

[Discuss-gnuradio] Template Error

Hi, I was converting the single channel FFT block to dual channel FFT block. I took the fft_vcc_fftw.cc code and tailored it for dual channel. Also I edited the corresponding xml file. But when I try to run it in any application from GRC, it says self.fft_vxx_0_0 = Template error: #if $type(

Re: [Discuss-gnuradio] USRP DDC and GNURadio Bandwidth Problem

Hi, I don't want my sampling rate to be 25 kHz. My sampling rate is already 195312 Hz which is I think the minimum sampling rate for X310. What I want is to filter out the frequencies which are at least 25 kHz away from my center frequency. For example I don't want to see a transmission which is

Re: [Discuss-gnuradio] [USRP-users] USRP DDC and GNURadio Bandwidth Problem

Hello Ali, The bandwidth parameter will select the Analog RF filters where possible. For the X310 the daughterboards do not have configurable filters so you will have to add a lowpass filter to your flowgraph. Regards, Derek On Thu, May 17, 2018 at 2:10 PM, Ali via USRP-users < usrp-us...@lists.

[Discuss-gnuradio] sample_rate and bandwidth parameter

Dear all, I have a question related to the parameters Samp Rate (Sps) and Bandwidth which can be found on the UHD USRP source and sink GNU radio blocks. If I want to calculate the bandwidth of a modulated signal (QPSK for example), the standard equation to use is usually: B = (1+roll-off)*

Re: [Discuss-gnuradio] USRP DDC and GNURadio Bandwidth Problem

Hello Ali, That "bandwidth" parameter of the UHD Source/Sink block is used to adjust the 'analog bandwidth' of the 'daughterboard'. Most of the daughterboards have a fixed analog bandwidth, so that parameter will be simply ignored in most cases ('uhd_usrp_probe' will give the detailed info abou

[Discuss-gnuradio] Invalid msg port in connect() or disconnect()

Hello list, I’m posting the following issue vicarious for GitHub user „mustaphos“, who unfortunately does not make use of the mailing list despite I directly suggested him to do so. Since I don’t think this is a gr-inspector issue, I’m posting this publicly for discussion. OP reports to have found

Re: [Discuss-gnuradio] gnuradio on High Sierra

Hi Vipin - Easiest way is to just install gnuradio-devel: {{{ sudo port -f deactivate gnuradio sudo port install gnuradio-devel }}} Assuming that the 2nd command works, then in your OOT when you "make" for the first time since this GR change CMake will redo configuration & you should be good to go.

Re: [Discuss-gnuradio] gnuradio on High Sierra

If I understood correctly, Vipin in trying to compile his own OOT. In that case, you can just switch to C++11 independently of GNU Radio AFAIK. You can do that by putting `set(CMAKE_CXX_STANDARD 11)` into your root CMakeLists.txt. Sebastian Müller gse...@gmail.com PGP ID DC2AA3EE

[Discuss-gnuradio] VCO

Hi all, I would like to ask about the VCO in GRC. What's the function of the sensitivity? If I connect a signal source (Saw Tooth) into VCO, and I want a bandwidth of 2MHz. I only can achieve it by setting the Sentivity = 2e6 *(2*3.1416) . Can anyone explain the theory behind this? Thank you!
