Hi, When I follow the steps listed on "http://gnuradio.org/trac/wiki/UdevConfig"; to configure non-root access to the USRP. The first step is: Define a group named usrp. $ sudo addgroup usrp but terminal returns "sudo: addgroup: command not found" Does anyone meet the same problem, and any

[Discuss-gnuradio] Migration from GNU Radio 2.8 to 3.1.2

I am returning to GNU Radio development after a considerable absence. I would like to start by testing some of the "simple" code I developed for GNU Radio 2.8 in the latest version of GNU Radio (3.1.2). The code was developed to utilize the USRP to tune multiple AM and FM channels. What are

Here is a patch to add windowing to gcell/src/lib/wrapper/spu/gcs_fft_1d_r2.c , seems quick and snappy: 24a25 > #include 50a52 > 52,53c54,69 < // FIXME pointwise multiply in *= window < assert(0); --- > /* pointwise multiply: in *= window > * > * shuffle pattern to make

[Discuss-gnuradio] No decimation -- collect at 64MHz

Hi, I am troubleshooting a problem with my GPS receiver. Is it possible to collect some 64 MHz data? I understand the collect will not be long because USB2 can't handle the bandwidth, but perhaps buffers on the USRP will allow me to make a 1ms collect? Thanks, Chris

[Discuss-gnuradio] The type of the connector on the DBSRX-LF rev

Hi all I want to buy several female connectors for USRP. I want to buy the same kind of female connector as the golden one on the DBSRX-LF rev which can connect with input signal. My problem is I do not know the name of this kind of connector, the type and which website to buy such kind of devise.
