The DBPSK blocks are in GRC under DPSK, there is a drop down to choose
between DBPSK, DQPSK, D8PSK. Also, see the packet encoder/decoder to
accompany the DPSK modulator blocks.
A helpful example:

Have you looked at the examples in the 'digital' folder? The
benchmark_rx and benchmark_tx do DBPSK, DQPSK, and others 'all the
way', if you are set on BPSK you simply comment out the differential
encoder/decoder in modulator/demodulator script.
