But the University IT guy 'knows all about radio.' Meh.
That's likely what happened.
Several of the UC campuses still have dedicated or at least part time radio guys (me included). Not sure about the CSU system. I'll have to ask them. It is all under the IT heading now, good or bad.
Smaller campuses rely on an IT guy who might have it as a collateral duty, and even then, most of the real work gets contracted out. I suspect that is what happened here. Someone set up the system for them. Guy said it was OK, and the bill was paid.
Likely would have continued on unless someone complained.
CSU Hayward is up the hill a bit, so they'd have a pretty commanding view of the bay area, kind of hard for them to not notice someone else was on the frequency.
