[USRP-users] Could this be Ettus X310 self jamming problem?

In terms of GRC, how could I adjust master_clock_rate to 120MHz? Is there a setting in the USRP source properties? 
thanks,

Try repeating your test with a master_clock_rate of 120MHz rather than 200MHz. This should change the frequencies of harmonics related to the default radio clock.
