 HD receivers were limited in new vehicles; HD Radios were not portable; smartphones were becoming popular with downloadable music from iTunes and popular music service apps such as Pandora and Spotify; and there was considerable consumer confusion between HD television (which the FCC mandated TV stations to move from analog to digital OTA broadcasts) and HD Radio (which was not mandated for radio stations to stop broadcasting in analog).After a few years, KCSC's HD transmitter failed on the secondary channel and not replaced.The student radio station was off air indefinitely.
