[Discuss-gnuradio] Using external clock references in GRC environment

[Nazmul Islam]

Hello,

I am running two USRP2's with a 10 MHz external clock. I am using gnuradio-companion to transmit data between the USRP's. I have changed the clock source option as 'external' in the UHD:USRP Source & Sinc blocks. I kept the time source and clock rate block as default since I am not providing any external pps.  

Unfortunately, I am getting unexpected and wrong outputs. Do I need to make any other changes in the USRP Source & Sink options? 

Thanks,

Nazmul
