1960s
What began as 94.3 WQMF (1,000w Ant 120 feet) came about in September 1961 when 103.5 WGLI-FM moved from Babylon to Lake Success. Owner Friendly Frost, a Long Island based appliance store chain, applied for another FM frequency to replace 103.5 in the Babylon area and WQMF was born. Federal Communications Commission (FCC) rules prohibited ownership of overlapping signals but because the new WGLI-FM antenna was located on a 175 foot tower (20Kw) alongside the Long Island Expressway right on the Queens-Nassau border its new signal did not cover Babylon (this would become an issue a few years later).
WQMF was one of the first totally automated radio stations in the area and maybe the country. Its equipment package was named "Silent Sam" by engineers assigned to operate it as it played "beautiful music" from audio tapes supplied by a syndicator. The engineers' main function was tending to WQMF’s sister station 1290 WGLI which required first class FCC licensed personnel because of its three tower directional antenna (1290 WGLI was shut down permanently in 1989).
In 1965 what was now 103.5 WTFM obtained a construction permit to move its transmitter to the Chrysler Building in Manhattan but big new coverage from a 950 foot antenna (7.1Kw H 4.6Kw V) produced an overlapping signal with what was now 94.3 WGLI-FM. So a quick sale sent 94.3 WGLI-FM to Greater Media, a New Jersey based group broadcaster, who had just acquired WGSM (740 AM) in Huntington. Greater Media paid just $90,000.00 dollars ($665,000.00 2013 money) for the facility which was renamed WGSM-FM and began simulcasting WGSM (AM) with transmitter and antenna remaining at the WGLI complex.
1970s and 1980s
The arrangement continued until 1970 when the station moved its transmitter and antenna to a location in Brentwood where it remains to this day. As part of the move, WGSM-FM's COL changed from Babylon to Smithtown. After the move was completed 94.3 became WCTO ("WCTO Stereo") and began a twenty year run playing easy listening music and earning top ratings which have never been duplicated by the many incarnations that would follow. (Example: 1975 ARB rating listeners 18-49 10A-3P M-F, WCTO was the number one LI radio station)
1990s and 2000s
In June 1990 a switch to a popular light AC format as WMJC ("Magic 94.3") under the guidance of Jack Kratoville (now at WLTW), then purchased by WRCN-FM radio in 1994 and simulcast the rock format from 1994-1996. After the rock experiment failed... it began to simulcast its sister station WGSM, which was carrying a country format at the time. WMJC eventually would adopt that format exclusively as "Country 94.3" when WGSM became Radio Disney. On November 10, 2000, the country format was dropped and WMJC became "Island 94-3" playing rock hits of the '80's and '90's with Charlie Lombardo (aka "Jay Letterman" from WALK-FM) as PD. By 2007, the branding changed to "94.3 WMJC", along with a music mix adjustment to Adult Top 40.
2010 to present
As mentioned, the station never achieved ratings anywhere near the high water mark set by WCTO and by mid 2010 was hovering in the 1 range. On October 19, 2010 came its sixth call letter change, from WMJC to WIGX, leading to rumors of a format change. Those rumors would prove true on November 5, 2010, when, at 4:30 PM, 94.3 began stunting with a montage of music, famous news, and TV snippets from each year it would cover in the new format, from 1985 to 2005. At 5PM WIGX switched to a "Gen X hits" format, playing hit music from 1985 to 2005, as "94X". The first song on 94X was Jump Around by House of Pain. This version of 94.3 failed to achieve higher ratings and that brought about yet another change. At Noon on September 14, 2012, after playing Semisonic's Closing Time followed by the US National Anthem, WIGX aired a brief clip from the movie trailer for Jaws and switched to mainstream rock, branded as "94.3 The Shark", launching with Nirvana's Smells Like Teen Spirit. Soon after, WIGX switched to its seventh set of call letters, WWSK.
