ALL of the pioneering educational broadcasters ended up on bad daytime-only facilities, and deliberately so, thanks to DoC/FRC/early FCC policies that heavily favored commercial broadcasters.
WOSU, WKAR, KUSD, WBAA, WOI, WILL, WSUI, WHA, WLBL, KOAC, KWSC/KWSU, KUOM and so on - all date back to the very earliest group of licensees and all were limited to daytime-only or shoved into bad time-shares by regulators who repeatedly denied any semblance of an even playing field.
The only stations that were owned by educational institutions in that era that ended up with decent facilities were the ones that were sold off or operated fully commercially - KOB, WWL and WHAM most prominent among them.
