G'day,
I've found various implementations of SSB demodulators but no modulators? Has
anyone written or seen an implementation of a SSB modulator?

Here you go:
real_sig = <whatever> # at 250k samples/sec
f2c = gr.float_to_complex()
u = usrp.sink_c(0, interp_rate=512)
fg.connect(real_sig, f2c, u)

Actually, that will get you a double sideband signal. You need to use a
hilbert transform to create the imaginary part. Hilbert transforms are
in firdes code already.
