[Discuss-gnuradio] continuous data collection? |

I've been collecting snapshots through my DBS and USRP to do DBPSK and DQPSK
bit error rate testing. I'm not able to get the BER below about 1e-5. It
seems that slips are occuring spontaneously in the data even though no
over/underflow is reported during the collection.
Questions:
1. Has anyone successfully done long term collections without any slips?
2. Are the O/U flags sticky?, i.e. if I don't see an under or overflow
reported then I can be sure the fifos were okay?
I've done BERs from 1 Mbaud to 11 Mbaud all with the same frequency of slips
so it does not appear to be speed related.
Thanks,
Clark
