In September 2006, to accommodate the growing demand for an all-NPR news and information service, KUHF began broadcasting in HD Radio offering three channels of digital programming in addition to the analog FM: HD channel one offered the same programming as was heard on FM, while HD channel two was a "mirror" of FM/HD-1 by offering classical music during times the other channel played news and informational programming, and vice versa. In this fashion, KUHF HD listeners could receive either NPR news/information or classical music any time of day or night, 24/7. Since KUHA's shutdown in July 2016, KUHF 88.7FM and HD-1 feature NPR news/information exclusively, 24 hours a day, and HD-2 features classical music (exclusively from Classical 24 since November 7, 2013). The HD-2 channel was a simulcast of KUHA from May 2011 until May 2016, when the simulcast broke off in preparation of the sale to the KSBJ Educational Foundation. KUHA began airing delayed repeats of 88.7 HD-2's programming several hours or days after it had aired on 88.7 HD-2. HD Channel 3 carries a mixture of XPoNential Radio, an Adult album alternative station provided by Philadelphia-based public radio station WXPN, and the BBC World Service.
