I'm not sure what code you started from, Eric S. ... I had mentioned I 
had some fixes in my own developer branch, one of which was making sure 
there was only 1 counter:
http://gnuradio.org/trac/changeset/8987
http://gnuradio.org/trac/changeset/8988
http://gnuradio.org/trac/changeset/8990

I think that we're talking about the same thing here.
