Some HD‑2 or HD‑3 stations are even simulcasting sister AM stations. In St. Louis, for example, clear-channel KMOX‑AM (1120 kHz analog and HD) is simulcast on KEZK-FM 102.5 FM‑HD3. KBCO‑FM in Boulder, Colorado, uses its HD‑2 channel to broadcast exclusive live recordings from their private recording studio. CBS Radio is implementing plans to introduce its more popular superstations into distant markets (KROQ-FM into New York City, WFAN‑AM into Florida, and KFRG-FM and KSCF‑FM into Los Angeles) via HD‑2 and HD‑3 channels. On 8 March 2009, CBS Radio inaugurated the first station with an HD4 subchannel, WJFK-FM in Washington, D.C., a sports radio station which also carries sister sports operations WJZ-FM from Baltimore; Philadelphia's WTEL‑AM and WIP-FM; and WFAN‑AM from New York. Since then numerous other channels have implemented HD‑4 subchannels as well, although with nearly 100% talk-based formats, because of the reduced audio quality. For example, KKLQ‑FM in Los Angeles operates an HD‑4 signal and aired The Mormon Channel which was 99% talk. Public broadcasters are also embracing HD Radio. Minnesota Public Radio offers a few services: KNOW-FM, the MPR News station in the Twin Cities, offers music service Radio Heartland on 91.1 FM‑HD2 and additional news programming called "BBC News and More" on 91.1 FM‑HD3; KSJN-FM, the classical MPR station in the Twin Cities, provides "Classical 24" service on 99.5 FM‑HD2; and KCMP-FM, on 89.3 FM in the Twin Cities, offers "Wonderground Radio", music for kids and their parents, on 89.3 FM‑HD2. KPCC‑FM (Southern California Public Radio), heard on 89.3 FM in Los Angeles, offers a digital simulcast of its analog channel on 89.3 FM‑HD1 and MPR's music service KCMP-FM on 89.3 FM‑HD2 in Los Angeles. New York Public Radio in New York City, WNYC-AM and WNYC-FM, (d.b.a. WNYC) re-broadcasts a locally programmed, all-classical service from WQXR-FM called "Q2", on 93.9 FM‑HD2. The service launched in March 2006. On 8 October 2009, the format was moved to WQXR‑HD2 (WXNY-FM) on 105.9 FM when WQXR-FM was acquired by New York Public Radio as part of a frequency swap with Univision Radio for their former frequency. The programming on the WNYC-FM‑HD2 channel now is a rebroadcast of WQXR-FM, in order to give full coverage of WQXR-FM programming in some form, as the 105.9 FM signal is weaker, and does not cover the whole area. WMIL-FM in Milwaukee has offered an audio simulcast of Fox affiliate WITI‑TV on their HD‑3 subchannel since
