[USRP-users] USRP under run when when trying to send messages in a low rate

Hi Damindra,

it's a bit too much guesswork involved if you don't share *what* kind of
application in GNU Radio you're designing. And a few parameters would be
helpful too: something like sampling rate of the USRP, which USRP type
you're using.

Generally, an underrun means your computer wasn't fast enough at
providing samples to your USRP.

Best regards,
