Thank you for the replies. I succeeded in using a clock rate of 184.32Mhz and a sample rate of 30.72MHz. -- View this message in context: http://gnuradio.4.n7.nabble.com/Usrp-x310-LTE-support-with-without-external-clock-tp50748p51280.html Sent from the GnuRadio mailing list archive at Nabble.co

I'm new to gnuradio and sdr. I'm looking to use a x310 usrp in an lte project. I have read it can support a 184.32MHz clock frequency which is great for LTE and a sample rate of 30.72MHz. I have looked at the uhd source code. I get the impression that the lte frequencies can only be supported
