Tom, Is there going to be a fix soon or should I go with the 3.6.5 version of gnuradio? Thanks, -George On Dec 18, 2013, at 7:01 PM, George wrote: > Hi Tom, > > You are right increasing the number of taps by 100 is not the case, after I > debugged the results a bit more. > The problem see

Hi Tom, You are right increasing the number of taps by 100 is not the case, after I debugged the results a bit more. The problem seems to be in the number of samples consumed as you mentioned above. The full definition for the filter I am using is firdes.root_raised_cosine(nfilts, 1.0, 1.0/nf
