Niner, in defense of WBFO's airing of Xponential radio on its HD2 channel, please keep in mind that HD doesn't yet justify the expenditure of money it would take to operate the channel with a local staff and format. NPR is making available various formats (classical, jazz, news/talk and AAA) at little cost that stations can put on their HD channels. If such a service were not available, public stations throughout the country would be mirroring their main programming on their HD2 channels.
Also know that WBFO received a state music grant from the payola settlement that is allowing the station to begin a series of local music programs. Starting in October, WBFO will air a weekly concert at 8pm Wednesdays, live from its Allen Hall auditorium, featuring local bands. Then, Fridays at 8, the station will run "Buffalo Avenues," a one-hour local music program with artist interviews and music. From what I hear, both shows will be replayed throughout the week on WBFO HD2.
One other note. While most people haven't purchased an HD radio yet, the Xponential feed is available on WBFO's website, making it available to anyone with a computer.
