The station's signal is relayed on fill-in low-power translator station on UHF channel 17, which operates its transmitter facilities in Park City.

History

In June 1965, the Garvey Foundation purchased a transmitter site in Hutchinson, with the intent to start a non-commercial educational television station. Shortly afterward, on July 21, 1965, the Sunflower Educational Television Corporation was chartered to start a public television station for the Wichita market. A year later, the SETC's board of trustees filed for a construction permit with the Federal Communications Commission for a non-commercial educational license on VHF channel 8, which was eventually assigned KPTS as its call letters.

The station first signed on the air on January 5, 1970;[2] for its first ten months on the air, it served as a member station of National Educational Television, before becoming a member of the Public Broadcasting Service (PBS) when it launched on October 6, 1970. In 1978, Sunflower Educational Television Corporation was reorganized as the Kansas Public Telecommunications Service. In 1980, the station moved to its current studio facility at 320 West 21st Street North in Wichita.

Analog-to-digital conversion

The station signed on its digital signal on channel 8 at 10 a.m. February 16, 2008.[4] KPTS shut down its analog signal, over VHF channel 8, on January 5, 2009; one month later on February 18, the station's digital signal relocated from its pre-transition UHF channel 29 to VHF channel 8.[4][5][6]

Due to reception problems that occurred after the transition due to the short height of its previous transmitter tower near Buhler and the fact that the transmitter operated at a lower power that limited the station's coverage area, resulting in signal loss issues – especially in areas of lower terrain located south and east of Wichita, KPTS began raising funds to sign on a fill-in translator from a tower north of Wichita in 2011. Plans called for construction on the tower to begin in the summer of 2013 with the translator signing on by September; however, these plans were delayed due to frequent occurrences of record rainfall during July and August.[7][8][9] The translator began operating on November 8, 2013.
