WKMJ-TV

PBS member station in Louisville, Kentucky

However, after this arrangement, duplication returned. In 1995, after WKPC TV experienced a series of financial reversals caused by for profit ventures intended to bolster station income, talks about intending to merge the two stations began, with channel 15—with its stronger signal—becoming the primary KET station. An agreement was reached in December 1996, by which KET acquired certain technical assets, including the land to the Floyds Knobs tower it still shared with WKPC TV, and the license.

On July 1, 1997, KET's main programming moved to WKPC TV. WKMJ TV simultaneously suspended operations for a transmitter overhaul; it returned a month later at increased power, carrying a new service called KET2, which initially featured additional children's programs, adult education programming and local productions. Outside of Louisville, KET2 was seen on cable systems statewide; it also replaced the cable only KET Etc. service in Lexington, an earlier attempt in launching a second programming service.

In 2009, WKMJ DT2 began broadcasting the Kentucky Channel, simulcasting the DT3 subchannel of KET's other stations. At the same time, KET ED, the Education Channel became available on WKMJ DT3 on a 24 hour a day basis; this ended in September 2009, when WKMJ DT3 went silent for four years following that linear service's discontinuation. In 2013, WKMJ DT3 began broadcasting the World network by American Public Television (APT). As the only KET station broadcasting that network, Louisville was the only major market in Kentucky to receive that channel until 2023, when the network began offering it on WCVN TV's ATSC 3.0 signal in Covington. In late 2020, WKMJ TV's main channel was upgraded to 720p HD, with KETKY on 68.2 upgraded to widescreen standard definition. This upgrade also took place on the DT2 and DT3 feeds of all other KET satellites.

As the second service of KET, WKMJ TV broadcasts the national PBS schedule from the PBS Satellite Service along with additional syndicated programs from American Public Television (including how to programs, documentaries, and imported comedy and drama series), Kentucky focused public affairs programs, and some local programming focusing on the Louisville area. as of 2023, WKMJ TV does not air children's programming broadcast by PBS or through independent distributors; this is despite that FCC Children's Television Act regulations (which require television stations to air a minimum of three hours of educational children's programming per week) apply to WKMJ, as it transmits the KET2 schedule locally. (While KET2 is simulcast on the DT2 subchannel of KET's other stations, exemptions to Children's Television Act enforcement—as implemented in January 2020—only apply to services transmitted exclusively through subchannels.)

KET2 was originally available exclusively in the Louisville market over the air upon its launch in 1997; some cable systems elsewhere in Kentucky, including systems in Lexington, began to carry the service. The over the air statewide relaunch of KET2, via the digital television signals of all KET stations broadcasting the statewide feed, occurred in 2002 by making it available through a second digital subchannel. The 15 principal KET satellites and 3 accompanying digital low powered translators presently provide KET2 on their respective DT2 subchannels. Currently, KET2's cable carriage covers roughly 62% of all subscribers in the state. This includes most Charter Spectrum systems, including all of the state's major cities and several rural areas. It is also available on DirecTV and Dish Network satellite television in the Louisville market. KET2 is also available on cable in Louisville's southern Indiana suburbs.

On April 16, 2009, WKMJ TV shut down its analog signal on UHF channel 68 in compliance with the federally mandated digital television transition. The station's digital signal remained on its pre transition UHF channel 38. Digital television receivers display the station's virtual channel as 68, its former UHF analog channel, which was one of the upper band UHF channels (52–69) that was discontinued for broadcast television use with that transition.

In July 2017, WKMJ TV held a construction permit to move its digital signal to UHF channel 34 as part of the network's participation in the 2016–17 FCC Spectrum incentive auction. WKMJ's digital signal was reallocated to its new position in October 2019.
