What happens, for instance, if UofR officials someday decides they want full control of WRUR; meaning they no longer want to be affiliated with WXXI and instead want the station to be controlled by students?
It's a valid concern, but the likelihood of that happening is quite remote. There has to be some form of LMA in place, and no doubt it's a multi-year contract. Even if that contract comes due within another 1 or 2 years from now, that's more than enough time for WRUR to cement itself in the local Rochester mindset as a successful public radio outlet under the WXXI management and branding.
Now imagine what happens if U of R decides "too bad, we're taking WRUR back and doing it ourselves." They're going to find themselves trapped between two VERY unattractive options. Either end WRUR's run as a pubradio outlet, and endure incredible wrath from the local community...a community U of R depends on for charitable giving, I might add. Or, they try and keep running it as a pubradio outlet on their own, and discover that they have to hire five fulltime staff for the station (NPR membership rules) and deal with the slight problem that WXXI has locked up a lot of the affiliate rights to NPR, APM and PRI programming in the Rochester market. Even if U of R can get around that (and admittedly they probably could) they'd still run into the unpleasant costs of that programming, which would easily be in the high six figures, possibly into seven figures.
And WXXI might get nasty and boot them off the Pinnacle Hill tower. That means finding new tower space and that's expensive. All the moreso since they can't move back on-campus; WRUR was already booted OFF campus once before because of signal blanketing problems on the campus.
Either way, U of R would be incurring substantial monetary outlay for something that brings them no more benefit than the existing arrangement does now. Even in good financial times, I don't see the administration doing that. Especially not considering the shape WRUR was in before WXXI saved it.
"But what about the students," you might ask? Fair enough. First of all, there ARE students on WRUR. Maybe not doing/saying EXACTLY what they want to do/say, but that's not big-bad-WXXI, that's just good management of a student activity....running a successful radio station does not mean letting the inmates run the asylum, after all. Second, I believe WXXI is helping U of R set up a webcast "radio station" to be "on the air" whenever WXXI is programming WRUR. Considering how few of my students even own an AM/FM radio these days, yet ALL of them own a laptop or iPhone, I think a webradio station makes a lot of sense.
