Actually, a collaboration with WTBU's newscasters on WBUR's HD2 is something I've suggested to multiple people in WBUR and COM over the years. Nobody's really interested.*** Oh well.
It's a shame. I stay in touch with the faculty advisor of WTBU now and then, but I don't really know too much about the details these days. But when I was there and at least for a few years afterwards (and I suspect it's still true today) there was a sizable newscaster crew at WTBU. Usually 20 to 50 students on a given year. When I asked last year I was told student involvement was at an all-time high so I wouldn't be surprised if it's even more. BU has a hefty journalism curriculum in the College of Communication, after all. In theory you could set up the kids on, well, call it an advanced mentorship program with WBUR and let them experiment with things on the HD2. It wouldn't be for an on-campus audience, and it wouldn't be what most people think of as "college radio" either; this would be an alternative news outlet, for lack of a better term.
This reminds me, though. I need to talk to said faculty advisor and see if they're planning on applying for an LPFM. In theory they could do it, although it'd take some waivers. Certainly as an alum I'd be interested in trying to help.
*** The last time I tried, Paul LaCamera was still GM. He hated HD Radio. Told me point blank he thought it had no future and he wasn't gonna waste any money on it. I thought it was a somewhat narrow-minded opinion, but especially given the times, it was a position I couldn't argue with. I've never met Charlie Kravetz so I don't know how he feels about HD Radio multicasting, nor how he feels about BU's journalism program.
