        Yes, and no.   Most signals you might be interested in are, but
not all ... there are lots and lots of SD DSNG signals from satellite
news trucks with symbol rates around 3978.7 Ksym/sec (a standard for a
5.5 Mbs transport stream with 3/4 FEC) and a few other rates near that
in use.   These signals should be narrow enough to work with the USRP.

        I am hoping the USRP II will have the resources to do full
transponder DVB-S and DVB-S2 stuff in some mode or another - there is
definately a need for this for signal analysis/transponder IDing...
