1 milliwatt legally, though I'll bet some of the stations on there now have a lot more power than that (but are
not being shut down). As far as I know the only licensed station on the X-band is Logan Info at 1650. Most
of the pirates seem to be foreign language, but now that Rumba has arrived I would think the Hispanic
audience might no longer see a need and maybe there's room for someone to go on (but, legally...?) As for the FCC, I'm not sure they could license somebody and if so,
at a power that would serve a large number of people.
For now there's always the college/public stations that do offer shows like Democracy Now (and WMWM's Thu
night block comes to mind)...
