[srslte-users] Version 19.03 PRB 100 issue

[Ismael Gomez]

Hi Bilal,

Thanks for reporting. We'll have a look when we have the chance. In the
meantime, can you run

/usr/lib/uhd/examples/benchmark_rate --rx_rate 20e6 --tx_rate 20e6
--duration 60

with 20 MHz sampling rate to verify the X300 is streaming data correctly?

thanks
