 This is clearly a question for the discuss-GnURadio mailing list, not here.  
But there are delay blocks in GR. And you can effect a simple phase shift with a \
complex multiply.

Hi all,
I have a dual tone signal that I down converte and split into two signals with a \
common frequency with the Xlating-fir filter. So far so good. 

However I noticed there is a phase shift between the signals generated (I assume this \
is due the filter delay). I have to compensate for that. The question: How to \
determine or estimate that delay? Thank you,
