Re: [Discuss-gnuradio] spectrum record

[Marcus Müller]

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

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.
Thanks in advance
