KTWU, on digital channel 11, is a Public Broadcasting Service (PBS) Public television station in Topeka, Kansas. The station is operated by Washburn University and provides public television service to eastern Kansas. The station also is carried by some cable systems in the Kansas City metro area.

In its on-the-hour ID, KTWU actively promotes its repeater, K30AL-D channel 30, licensed to Iola, Kansas, with its transmitter located near Moran. K30AL-D serves the Iola, Fort Scott, and Chanute areas in southeast Kansas. It switched to digital-only rebroadcast of KTWU's signal in 2009.

History[edit]

On October 21, 1965, KTWU signed on as the first public television station in the state.

Digital channels[edit]

The station's digital signal is multiplexed:

Channel Video Aspect PSIP Short Name Programming[1]

11.2 480i 4:3 KTWU-DT2 MHz Worldview (8 p.m.-6 p.m.)

Analog-to-digital conversion[edit]

KTWU shut down its analog signal, over VHF channel 11, on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal relocated from its pre-transition UHF channel 23 to VHF channel 11.[2][3]

KTWU had applied for construction permits for Lawrence, Manhattan and Emporia for UHF translator stations, but due to the high cost of purchasing, installation and operating the proposed translators, combined with the loss of state and federal funding, they were unable to proceed with the construction.[citation needed]
