Inner City Broadcasting has (finally!) added HD to the signal at 107.5 FM New York. The HD-1 signal is the broadcast of the main signal's Urban AC format, while the HD-2 signal is simulcasting the gospel music format that is on Inner City's WLIB-AM-1190 New York. (Note: a gospel music format was on Emmis' WRKS-98.7 HD-2 before the Hum Desi format was moved from Emmis' WQHT-97.1 HD-3 to KISS-FM's HD-2.) There's no mention of these additions on either station's website (at least that I could find).
