WDXR-TV began as a commercial independent station on May 31, 1971. Local businessman E. Weeks McKinney-Smith, his wife Lady Sarah McKinney-Smith, and George T. Bailey each owned a 33.3% interest in the station. E. Weeks and Lady Sarah also owned WDXR radio. Lady Sarah became the sole owner of WDXR, Inc. after Mr. Weeks died in February 1974. A typical broadcast day on WDXR-TV consisted of public domainmovies and/or cartoons, barter, syndicated sitcoms and/or drama shows, and some religious programming. However, at one point, the station also aired a few newscasts of their own focusing on Western Kentucky's Jackson Purchase region, competing with the news department of locally-based NBC affiliate WPSD-TV. Paducah Broadcasters Inc. purchased both WDXR-TV and WDXR radio in December 1977.
As a KET satellite
On February 28 1978, Paducah Broadcasters Inc. donated the license of WDXR to the Kentucky Authority for Educational Television. Later that year, it was briefly taken off the air and converted into a relay station of the Kentucky Educational Television network. It returned to the air on April 17, 1978, and has been part of that statewide network ever since. This made WKPD the fifteenth full-power station in Kentucky to become a KET satellite. Until that time, WSIU-TV in Carbondale, Illinois was the only source for NET/PBS programming in the area. In the nine years between October 1968 and the format transition, WKMU-TV in Murray, Kentucky was the default KET satellite for the Purchase region, but it didn't have complete signal coverage over the entire region. WKPD's conversion into a KET satellite expanded signal coverage for the Purchase region, and provided a second option for PBS programming for far-southern Illinois.
The main channel of WKPD is available on DirecTV and Dish Networksatellite television in the entirety of the Paducah–Cape Girardeau market, including both customers who live on the Illinois or Missouri sides of the market, and the Paducah market's two other principal cities of Cape Girardeau, Missouri and Harrisburg, Illinois. All cable television providers in the Kentucky segment of the media market provide at least the main channel of the network. WSIU is mostly carried on cable in the Illinois and Missouri segments of the DMA.
Digital television
Analog-to-digital conversion
WKPD-TV shut down its analog signal over UHF channel 29 in compliance with the 2009 digital television transition. Although the mandatory deadline was June 12, 2009, after the DTV Delay Act pushed back the deadline from February 17, the analog signal was shut down on April 16. The station's digital signal remained on its pre-transition UHF channel 41. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 29. WKPD currently holds a construction permit to move its digital signal to UHF channel 23 as part of the network's participation in the 2016–17 FCC Spectrum incentive auction.
