WPST

94.5 Early years (1965–2001)

The station first signed on the air at 94.5 MHz on August 7, 1965 as WCHR with a religious format. (The call letters referred to Christ.) But after 33 years, that all changed when Nassau Broadcasting Partners bought the station. November 10, 1997 saw the beginning of things to come when the FM station began to simulcast its programming on its co-owned AM station, WCHR 920 AM, in preparation for a format switch. On February 27, 1998, 94.5 FM started stunting with construction sound effects. On March 2, 1998 94.5 became "New Jersey's Oldies Station." The call letters WNJO were assigned on March 26, 1998.

94.5 The Hawk (2001–2005)

On November 1, 2001, WNJO switched to a classic hits format as "94.5 The Hawk." The call letters changed to WTHK on August 1, 2002 and the station slowly evolved into a classic rock station. On February 14, 2005, at 5pm, 94.5 switched frequencies and formats with 97.5 WPST. It became "94.5 PST," using the slogan "Number one for today's hit music." Matt Sneed was the first voice on 94.5 WPST, while Chris Puorro was the music director and Dave McKay was the program director at the time.

97.5 WPST Early Years (1949-2005)

97.5 signed on for testing on January 10, 1949, then officially on April 19, 1949, as WTOA. It was owned by the Mercer Broadcasting Company, which was a wholly owned subsidiary of the Trenton Times newspaper. WTOA started out broadcasting from 3pm to 11pm, with an ERP of 14,500 watts. Its original coverage area reached as far north as Brooklyn and as far west as Reading, Pennsylvania. 97.5 became WPST on September 13, 1971. The WPST call sign originally stood for "Passport Stereo Trenton," a station slogan at the time. Also, the WPST call letters had been on a Miami TV station now known as WPLG.

97.5 WPST was known for its mainstream Top 40/CHR format, which it's had for many years. Tom Taylor was the PD who launched the format in the mid 1970s, and did mornings on the station until 1987. In August 1975, owner Herb Hobler hired Phil Geiger from WCHL in Chapel Hill, North Carolina as the General Manager. Along with Tom Taylor, they revamped the station and coined the phrase, "From The Shore to The Poconos, the best music is on the FM, 97 WPST". They initially established an AOR format, and by the Fall of 1975, the station took off and eventually became the number one station in the market. Some WPST DJs over the years included Lee Tobin, John "Walt Ballard" Mellon, Ed Johnson, Doug James, John Brown, Eddie Davis, Trish Merelo, David Cooper, Andy Gury, Jeffrey "Jeff Woody" Fife, Dan Kelly, Brian Douglas, Melvin "Mel Toxic" Taylor, Kris Gamble, Jason "Big Jay" Sorensen, Gene Lanzoni, Bob Sorrentino, Dave Hoeffel, Tom Cunningham, Dave Moss, Michelle Stevens, Pat Gillen, Eric Johnson, Mark Sheppard, Andre Gardner, Phil Simon, Mike Kaplan, Tommy Jordan, Steve Trevelise, Joel Katz, Rich DeSisto, Jason Barsky, Scott Lowe, Joe LeCompte, Jeff Ryan, Mark Vanness, with Gabrielle Vaughn, and Chris Puorro.

94.5 PST (2005–present)

On February 14, 2005, at 5pm, 97.5 switched frequencies and formats with 94.5 WTHK, and adopted its adult top 40 format. This cut into the audience for Philadelphia's hot adult contemporary 95.7 WMWX, which became adult hits two months later and the following year switching its call letters to WBEN-FM. Nielsen BDS & Mediabase still reported them as a contemporary hit radio station until 2008. The move left 102.1 WIOQ Philadelphia as the only mainstream top 40 station in Philadelphia and Trenton, with WSTW also heard in nearby Wilmington, Delaware. In August 2005, 97.5's city of license was changed from Trenton to Burlington, New Jersey. Before moving closer to Philadelphia, the 97.5 transmitter was located in downtown Trenton, New Jersey. The tower from which 97.5 broadcast is the tallest structure in the City of Trenton.

By 2011, WPST returned to a Top 40/CHR format, according to Mediabase & Nielsen BDS reports.

The station, along with nine other Nassau stations in New Jersey and Pennsylvania, was purchased at bankruptcy auction by NB Broadcasting in May 2012. NB Broadcasting is controlled by Nassau's creditors — Goldman Sachs, Pluss Enterprises, and P.E. Capital.^[6][7] In November, NB Broadcasting filed a motion to assign its rights to the stations to Connoisseur Media.^[8] The sale to Connoisseur Media, at a price of $38.7 million, was consummated on May 29, 2013.

WPST competitor WZMP flipped to AC in January 2017. WZMP's change leaves WPST and WIOQ the only two Top 40 stations in the Philadelphia/Delaware Valley market.
