I found them here:

Unfortunately they won't work with current version of gnuradio.
Anyway you should try something like this for BFSK modulation:

for the TX:
        ...
        self.cpfsk_mod = gr.cpfsk_bc(modulation_index, 1,
self.samples_per_symbol)
        self.gain = gr.multiply_const_cc(16000)

        self.connect(self.src, self.cpfsk_mod, self.gain, self.usrp)

while in RX:
        ...
        self.demod = gr.quadrature_demod_cf(20)
        self.dec = gr.keep_one_in_n(gr.sizeof_float, self.decimation)
        self.slicer = gr.binary_slicer_fb()

        self.connect(self.usrp, self.demod, self.dec, self.slicer,
self.snk)
