I should have looked at BC Map II.. :) I looked all over their site, and didn't see anything about the actual radio facility. They seem to be pretty active on their site though, posting a constant stream of news items to their feeds.
They should have tried to get KNBS, just like the shortwave pirate. Seriously though, to think that an actual marijuana station is on the commercial airwaves is pretty amazing!
