The station began broadcasting on April 30, 1947, with the call letters WMCK, and under the ownership of the Mon-Yough Broadcasting Company. George Raikes was company president and Jack Craddock was general manager. Studios were located at 517 Market Street in McKeesport. Its initial programming included Pittsburgh Pirates baseball games. During the early years, the station broadcast at a full-time power of 1,000 watts, day and night, changing to a directional antenna pattern during the nighttime hours.
As WIXZ
Following its acquisition by WWZ Corporation, it was a Top 40 station with the call lettersWIXZ beginning in 1969. Its studios and offices were moved to the recently completed Monroeville Mall. Among its disc jockeys during the Top 40 era was Jeff Christie, better known today by his real name, Rush Limbaugh. On June 19, 1974, the station was sold to Renda Broadcasting Corporation. Anthony F. Renda was the company president and Melvin Abramovitz was appointed as station manager. By the end of the decade, the station changed its format to country and the studios and offices were moved to 400 Lincoln Highway in East McKeesport. On July 16, 1985, Renda Broadcasting Corporation sold WIXZ to Serena Communications, a company owned by Renda executive Alan C. Serena. Renda had acquired the Pittsburgh stations WJAS and WSHH the year before and was required to sell off WIXZ to comply with more stringent FCC ownership requirements which, at the time, limited owners to possess no more than one AM and one FM property in any given market. Serena maintained the format until September 1997, when Renda Broadcasting bought back the station after FCC ownership rules were relaxed.
As WPTT and WMNY
Shortly after the re-acquisition, WIXZ switched to a talk format, then took the WPTT call letters. On August 19, 2008, Renda Broadcasting announced that WPTT would be switching formats from talk to financial advice; this was accompanied by a call change to WMNY. In all of its incarnations since WMCK, the radio station has positioned itself as a Pittsburgh outlet, rather than directly addressing the suburb of McKeesport, despite a weak nighttime signal. On September 19, 2011, Renda Broadcasting announced that WMNY would return to its "AM News Talk 1360" format. This format contains numerous popular talk programs from the Talk Radio Network based radio network.
As WGBN
In July 2013, Renda Broadcasting announced that WMNY would be donated to Pentecostal Temple Development Corporation, licensee of WGBN in New Kensington. The transaction was completed on October 9, 2013. 1360 went off the air for about a month to allow engineering adjustments that would allow it to simulcast 1150's programming. The stations swapped call signs on March 1, 2014.
