The two stations share studios on East Rock Road on South Mountain in Allentown; WDPN's transmitter is located in the Roxborough section of Philadelphia.

WDPN-TV's origins lie in a construction permit granted to Ambassador Media in 1988 for a Jackson, Wyoming, satellite station of its ABC affiliate in Pocatello, Idaho, KPVI.

The new station, which signed on January 9, 1991,[5] as KJVI, served as a semi-satellite of KPVI for the Wyoming side of the Idaho Falls–Pocatello market, airing separate commercials.

The analog channel 2 signal traveled a very long distance under normal conditions, and KJWY had to operate at very low power since it was short-spaced to KBCI-TV in Boise, Idaho (now KBOI-TV), and KUTV in Salt Lake City, Utah.

On March 2, 2009, Sunbelt Communications Company filed an application with the FCC to sell KJWY to PMCM TV (whose principals own six Jersey Shore radio stations in Monmouth and Ocean counties as Press Communications, LLC); however, Sunbelt initially planned to retain control of KJWY under a local marketing agreement.

[11] The full Commission denied PMCM's application for review in a Memorandum Opinion and Order released on September 15, 2011;[12] however, this denial was reversed by the U.S. Court of Appeals for the D.C.

In late June 2014, the station announced the hiring of longtime Philadelphia television personality Larry Mendte as public affairs director.

[17] On December 17, 2015, PMCM TV agreed to sell KJWP to Allentown-based Maranatha Broadcasting Company (owner of WFMZ-TV) for an undisclosed price.
