WGMF is an AM broadcasting radio station licensed to the city of Nanticoke, Pennsylvania, and serves the Wilkes-Barre, Scranton, and Hazleton radio markets with a classic hits format, switching from adult standards and Tropical and Spanish language adult contemporary format in December 2008. The station simulcasts sister WGMM located in Tunkhannock, Pennsylvania. WGMF broadcasts at a frequency of 730 kHz with 1,000 watts of power during the daytime with a non-directional antenna. During the nighttime hours, the station must reduce its power substantially to 12 watts which limits its listen able area to just the local Nanticoke area. The power reduction at nighttime is required by rules set by the Federal Communications Commission in order to avoid interference from CKAC, a Canadian Class A radio station also on 730 kHz. WGMF also broadcasts at a frequency of 104.5 MHz with 27 watts of power from a site atop Dewey/West Mtn near Keyser Valley/Scranton, Pennsylvania, which covers Scranton, Old Forge, Avoca, Dickson City, Pittston, and Jessup, Pennsylvania. WGMF also broadcasts at a frequency of 92.5 MHz with 250 watts of power from a site atop Penobscot Mountain near Mountain Top, Pennsylvania, which covers Wilkes-Barre, Mountain Top, Wyoming, Nanticoke, Hazleton, Dallas, West Pittston, and Kingston, Pennsylvania.

The station changed ownership in 1958 to Attorney Martin Phillips and Wyoming Radio, Inc.

During the 1980s, WNAK started broadcasting with the Kahn-Hazeltine AM stereo system, the only northeastern Pennsylvania AM broadcasting station to use the system. In 2003, Seven-Thirty Broadcasters and WNAK were acquired by Route 81 Radio, based in West Chester, PA. From 2004 until 2006, WNAK was simulcast on the former WNAK-FM located in Carbondale, Pennsylvania at 94.3 MHz.
