In GRC I'm setting up a flow graph to modulate and demodulate a text
file (simulation and without the USRP).   DBPSK and D8PSK runs just fine
however with DQPSK I get the text but it is garbled in places?   Since
the same flow graphs, with the only differnece being menu picks in the
and demod blocks, could this be a bug?

Also.....I'm doing the same thing for BPSK and was wondering if I can
the Packet encoder and decoder with the MPSK reciever?   If so, how do I
do the type conversion from complex to byte?
