By day, WIZR transmits with 1,000 watts, but to avoid interference with other stations on 930 AM, at night it reduces power to 28 watts. Programming is also heard on two FM translators, at 102.9 MHz in Johnstown and 104.3 MHz in Northville.
With the decline of top 40 formats on AM, WIZR switched to the syndicated "Music of Your Life" format under the call sign WMYL (in reference to the format) in 1981. WIZR-FM signed off in 1982 and returned after a one-year absence, simulcasting the AM's adult standards format. In 1984, Joe Caruso acquired the stations and reinstated the WIZR call sign on the AM side, while the FM took on a new format and the WSRD call letters.
In early 1998, Joe Caruso sought to move FM 104.9 closer to the Albany market by securing a construction permit to relocate WSRD to Altamont, New York. Later that year, Pamal Broadcasting acquired both stations for $2.2 million. Upon the closure of the sale, former sister station WSRD moved to its new transmitter site and is now WINU, while WIZR began to carry ABC's now-defunct Timeless radio network.
In December 2008, WIZR went silent as Pamal Broadcasting prepared for the sale of the radio station. Eventually, Dr. Thomas J. Kuettel purchased the station in early 2010. He installed a classic country format under Dial Global's True Country satellite service on March 15, 2010. On June 1, 2011, the station changed to Dial Global's oldies network. In March 2013, WIZR changed FM translator frequencies to 102.9, also adopting a new slogan, "Your Home For Classic Hits", as Dial Global had changed and updated the format.
In April 2014, the sale of WIZR began, with the Cranesville Radio Network of Amsterdam, New York, purchasing it. The station was flipped to an adult contemporary format, with a change to hot adult contemporary coming in July 2014. The license transfer for WIZR and W243CV was consummated on October 31, 2014, at a price of $150,000. WIZR became the fourth station in the Cranesville Amsterdam cluster, joining WCSS, WKAJ, and WYVS.
Undated, WIZR changed to its current hot adult contemporary format which includes hit songs from the past five decades (from the 1970s to present) with a variety mix of pop music, R&B, rock, soft ac, classic hits and more. The stations' current branding is WIZR 930 AM and 102.9 FM The Star of Johnstown. WYVS 96.5 FM Speculator, New York is also included in WIZR's station identifications.
