KTMJ-CD (channel 43) is a low-power, Class A television station in Topeka, Kansas, United States, affiliated with the Fox network.

Even though KTMJ-CD operates a digital signal of its own, the low-power broadcasting radius does not reach the northern and eastern fringes of the Topeka market.

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.

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.

On July 7, 2008, New Vision Television (owner of NBC affiliate KSNT) announced its intention to buy KTMJ and its repeaters from Montgomery Communications.

[4][5] LIN and Vaughan Media (which concurrently purchased the PBC stations) also entered into a joint sales agreement to provide advertising services for KTKA.

[8] 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.

Four months later on February 10, 2009, the prime time news simulcast from WDAF was replaced by a half-hour newscast at 9 p.m. on Monday through Friday evenings.

[15] The station's 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.

KTLJ-CA had an application to broadcast its digital signal on UHF channel 46 from a transmitter on a tower located off of Liberty Hall Road (west of Junction City) currently occupied by University of Kansas–owned radio station KANV (91.3 FM).
