I have a usrp1 and want to execute usrp_wfm_rcv.py using TVRX daughterboard. ( Also tried to send a signal with gnuradio-companion. (Usrp-source + scope-sink) ) But an error occured : UHD error :

Property already exists at: /mboards/0/dboards/B/rx_frontends/0/name After this ı tried RFx1800 daughterboard with gnuradio-companion, then it worked. So usrp1 is seen by my computer. (no problem ) But TVRX board didn't worked !!!
