Hi Neil,
Can you please share some more details on how the end result could be same?

AFAIS, the problem is that GNU Radio doesn’t connect message ports when
restarting a flow graph.
If you add blocks with message ports, as you do durin
Hi John,
I really hate to nitpick, but I also feel that I must clarify a few things:

No, network mode works with the default (and only) FPGA image – it's
just a software daemon inside UHD.
Neil,
Yes. It does lock and track with those taps. But with about 0.2-0.3 dB of
added implementation loss.

Hi Usman,
I just verified that a raised cosine filter used for the pfb clock sync taps
will effectively shape a square wave and allow the synchronizer to properly
track the symbol timing. I wanted to be sure before I continued to push anybody
else down this path (now also verified by John, a
I updated my python-thrift to be 0.9.3 and the thrift is 0.9.3.
