KTMJ-CD

KTMJ traces its roots to the June 16, 1982 sign-on of K06KZ in Junction City, an independent station which broadcast on VHF channel 6. In 1987, the station changed its call letters to KTMJ-LP (representing the station's service area of Topeka, Manhattan and Junction City); however, the station was referenced as "KTMJ-TV 6" in the Kansas City edition of TV Guide and Topeka area newspapers. On April 6, 1987, the station became an affiliate of the Fox Broadcasting Company. KETM-LP signed on the air on November 30, 1988 as K17CK; also operating as an independent station initially, it was eventually converted into a repeater of the Junction City station, which served as the main signal. On March 30, 2011, it surrendered its Class A designation and reverted to a standard LPTV license; at that time, the station changed its call letters to KETM-LP. KMJT-CA began operating on August 4, 1992 as K15DQ; it became a Class A repeater of the original Junction City signal on September 24, 2001. On January 16, 1995, KTMJ-LP became a secondary affiliate of the United Paramount Network (UPN). Channel 43 originally maintained studio facilities located on Southgate Drive in southwestern Topeka.

In 2001, then-owner Montgomery Communications reassigned the KTMJ-CA call letters to the repeater on UHF channel 43 in Topeka, converting that outlet—which was also re-designated as a Class A station—into the flagship station of the group. At that time, channel 17 became a Class A station and changed its call letters to KETM-CA, subsequently becoming a repeater of channel 43. The Junction City station that originally held the KTMJ calls also had its call letters changed to KTLJ-CA. With the reassignment of the Topeka station as the originating station for KTMJ, Montgomery Communications relocated the station's operations from Junction City to facilities on Southgate Drive in southwest Topeka; master control operations remained in Junction City, before moving to the Topeka facility in May 2004.[1] KTMJ-CA and its repeaters dropped the secondary UPN affiliation in 2003.

On July 7, 2008, New Vision Television (owner of NBC affiliate KSNT) announced its intention to buy KTMJ and its repeaters from Montgomery Communications.[2] The purchase was completed on September 1. As a result, KTMJ relocated its operations into KSNT's facilities on Northwest 25th Street. In November 2008, KSNT began providing a simulcast of KTMJ-CA on its second digital subchannel, replacing CW Plus affiliate "Northeast Kansas CW 5" (which concurrently moved to present-day sister station KTKA-TV).

On May 7, 2012, LIN TV Corporation announced that it would acquire the New Vision Television station group, including KSNT and KTMJ-CD, for $330.4 million and the assumption of $12 million in debt. Along with the outright ownership of KSNT and KTMJ, the agreement included the acquisition of New Vision's shared services agreement with PBC Broadcasting, giving LIN operational control of KTKA-TV.[3][4] LIN and Vaughan Media (which concurrently purchased the PBC stations) also entered into a joint sales agreement to provide advertising services for KTKA.[5] The sale of New Vision to LIN Media and KTKA's purchase by Vaughan Media was approved by the FCC on October 2,[6] with the transaction closing on October 12, 2012.[7] The deal marked a re-entry into Kansas for LIN, who briefly owned the licenses of Wichita ABC affiliate KAKE and its satellites in 2000, but never held operational control of the stations.

On March 21, 2014, Media General announced that it would purchase the LIN Media stations, including KSNT, KTMJ-CD, and the SSA/JSA with KTKA-TV, in a $1.6 billion merger.[8] The FCC approved the merger on December 12, 2014, with the deal being consummated on December 19;[9] however as a condition of the sale's approval, Media General was originally required to terminate the joint sales agreement between KTKA-TV and KSNT within two years, due to the FCC's ban on agreements involving the sale of advertising encompassing more than 15% of a separately-owned station's airtime.[10]

The FCC cancelled the licenses for KMJT-LP (on April 3, 2017) and KETM-LP (on April 27, 2017).

The station's digital signal is multiplexed:

On September 1, 2010, KTMJ-CA filed an application with the Federal Communications Commission to flash-cut its digital signal into operation on its existing analog allocation on UHF channel 43; the FCC granted a construction permit to build the digital transmitter facility for KTMJ on September 28.[12] On September 29, 2011, KTMJ-CA began broadcasting its programming in high definition.

From June 16, 1982 until the transition to a digital-only signal, the signals of K06KZ (at first), KTMJ-LP and KTMJ-CA (both at the time of the transition), and now KTLJ-CA were audible on radio in the Junction City area on 87.7 FM; television stations broadcasting on VHF channel 6 were audible over this frequency during the analog television era as it coincided with the FM radio band, although this is no longer possible due to the transition to digital television, even for stations that broadcast their digital signals on channel 6. After KTLJ-CA converts to digital, it will become the last television station in Kansas broadcasting on analog channel 6 to cease broadcasting its audio on 87.7 FM radio station (after KSNW translator K06LZ in Salina in 2008, and KWCH satellite KBSD-DT in Dodge City when it switched on the official transition date of June 12, 2009).
