The station first went on the air in 1962 as WAPC-FM.[4] In 1967 the call letters were changed to WHRF-FM,[5] and in 1972 to the current WRCN-FM.[6] In 1978, WRCN changed from a top 40 format to what was then known as album-oriented rock (now known as classic rock). Some of the air–staff that have worked at the station over the years include, Zena Black,[7] Bob Buchmann,[8]Marc Coppola, John Loscalzo,[9] Tim Sheehan,[10]Dee Snider, and Chaz & AJ.[11]
On August 27, 2012, WRCN-FM shifted their format to mainstream rock, under the "Rock of Long Island" slogan.[12]
On November 15, 2013, at 5 pm, WRCN-FM's rock format came to an abrupt end as the station temporarily changed formats to Christmas music as "Christmas 103.9". The station then flipped to conservative news/talk as "LI News Radio 103.9" on December 26, 2013.[13]
