Hi, So do I need to install Ubuntu 18.10 to be able to stream 4 channels simultaneously by using rx_multi_samples.cpp or any other? What should be the kernel version? Regards, Koyel ___ USRP-users mailing list USRP-users@lists.ettus.com http://list

Hi everyone, I'm trying to implement a TDOA system using B200mini-i, since GPSDO is not an option for B200mini, can I send GPS time info to reference port? If so, how do realize it and is there any example or reference? Also is there any recommendation of the GPS receiver that I could test? Thank

So each port on the server/host must be on a different subnet? 192.168.1... 192.168.2... and so on? Also when you define NIC do you mean each individual port or the chip/card itself? In other words, is our Intel x520-DA2 (card with 2-SFP+ ports) one NIC or two? Thanks for the fast responses ev

So you installed GNU radio from source but what about UHD? Also how did you clone? dd? I've used clones before successfully with various Debian distros but I needed to compile both UHD and GNU radio from source (in that order). On Mon, Jan 21, 2019 at 8:33 PM Achilleas Anastasopoulos wrote:
