WLGX (100.5 FM) is a radio station broadcasting a Hot Adult Contemporary music format under the branding "100.5 Kiss FM". Licensed to Louisville, Kentucky, United States, the station serves the Louisville area. The station is owned by iHeartMedia and features programming from Premiere Radio Networks.[1] The station is also broadcast on HD radio.[2] The station's studios are located in the Louisville enclave of Watterson Park and the transmitter site is in east Louisville, southwest of the I-64/I-265 interchange.


The station was assigned call letters WTFX on June 28, 1991. On April 19, 2002, the station changed its call sign to WTFX-FM, on August 19, 2005 to WLUE, and an application was filed as of September 3, 2009, to change the call sign to WLGX.[3]

This station initially signed on with a classic rock format on June 7, 1993, which shifted more towards mainstream rock and then active rock by 2002, as 100.5 The Fox.[4] In 2005, The Fox moved to 93.1 and 100.5 flipped to variety hits as 100.5 Louie FM. On September 3, 2009, in response to slipping market share, the station decided to shift towards a 1990s pop/rock-centered offering called Gen-X Radio. According to a press release which was issued hours before the format change, the station promises to feature music from "grunge, hip-hop, hair bands and boy bands".

Since 2011, Gen-X Radio has temporarily dropped their 90's Hits format beginning in November each year for a Christmas music format, branded Gen X-Mas. During these times, they maintained a separate stream of the regular format under the same name on iHeartRadio.

In April 2014, the station branding was modified and changed to "My 100.5 Gen-X Radio". At the same time, the 1980s and 90s music was greatly reduced, and the playlist was modified to include a Hot Adult Contemporary mix of music generally focused towards the 1990s through today. On July 1, 2014, at midnight, WLGX was officially rebranded as 100.5 MYfm.

On May 25, 2016, WLGX rebranded as "100.5 Kiss FM".[5]
