Hi gsmandvoip, Your decimation seems about right (oh, I don't miss libusrp). I don't think you need to change the example, but please be aware that libusrp has become so obsolete that I don't even have the source code around anymore. I'm not totally sure you need to use libusrp to have openBTS (which is what I guess you mean by special purpose): http://wush.net/trac/rangepublic/wiki/BuildInstallRun I haven't tried, but I'm fairly certain that UHD still supports the B100/USRP1 (and that GNU Radio thus did not drop support for that on 3.5.0), and thus I don't really know why the combination OpenBTS and USRP1 calls for GR3.4.2; is there someone who could enlighten me? I'm fairly certain I've been sending text messages over openBTS that was operating a B210, so UHD&openBTS *should* work... Greetings, Marcus On 27.07.2014 12:08, gsmandvoip wrote:
Hi list, I want to record a 5MHz wide bandwidth with usrp1 (equipped with dbsrx1 and modified clock @ 52MHz), can anyone guide me how to do this, I am using usrp_rx_cfile (using gnuradio-3.4.2 for special purpose) with gain =52 decimation= 26 Please do let me know if I need to make any changes in any file to accomplish my task.
