over HD Radio subchannels, albeit with a drastically reduced affiliate base than it had up until the early 2010s.) Prior to CBS Corporation's 2017 sale of its radio properties to Entercom, in 2011, CBS Radio began using HD Radio technology to relay the signals of its major-market music-formatted stations to other markets around the country. For instance, KFRG (95.1 FM) in San Bernardino is carried on KTWV-HD3 (94.7 FM HD3) in Los Angeles, KSCF (103.7 FM, now KSON) in San Diego is heard on KAMP-HD2 (97.1 FM HD2) in Los Angeles; WBZ-FM (98.5 FM) in Boston was heard on WTIC-HD3 (96.5 FM HD3) in Hartford up until after Entercom sold WBZ-FM to the Beasley Broadcast Group in November 2017; KROQ-FM (106.7) in Los Angeles was formerly heard on KEGY (97.3 FM, now KWFN) in San Diego; and both WXRK-HD2 (92.3 FM HD2, now WINS-FM), and WFAN (660 AM) in New York City are respectively simulcast on three affiliates – WOCL-HD3 (105.9 FM HD3) in Orlando, WLLD-HD3 (94.1 FM HD3) in Tampa, and WEAT-HD3 (107.9 FM HD3) in West Palm Beach – in Florida. In many cases where radio stations distribute outside their home market, the local stations make some concessions, such as replacement of local advertisements with either national advertising or a bed of production music that plays over commercial breaks. Also in the example of WFAN, that station's play-by-play coverage of the New York Mets and Giants, the New Jersey Devils and the Brooklyn Nets is not carried on the Florida HD Radio affiliates and replaced with alternate programming, as the station only has rights to transmit the game broadcasts in the New York metropolitan area.
