Total new to SDR and Osmocom. I have USRP1 with clock-tamer installed. 1 daughtercard - RFX1800 <https://www.ettus.com/product/details/RFX1800>(I believe) I have been following this tutorial: http://openbsc.osmocom.org/trac/wiki/network_from_scratch My phones can see network but not register. Nothing comes up in the log file when phones try to connect. Not sure if its a config problem, or the external clock tamer, or something else. Attached is configs and screenshots Thanks, E
