WKLE is a non-commercial public television station that is licensed to Lexington, Kentucky, and serving the central Kentucky Bluegrass region. The station is the flagship station of the Kentucky Educational Television network (KET), and serves as a PBS affiliate owned by the Kentucky Authority for Educational Television.
The station’s master control hub and internal operations are located at KET’s main studios at the O. Leonard Press Telecommunications Center, located at 600 Cooper Drive in Lexington, Kentucky. The station transmits its signal on UHF channel 42 (virtual channel 46 via PSIP) from a transmitter tower located near the corner of Simpson Lane and Igo in northern Madison County near Boonesborough and the Fort Boonesborough State Park, and can be easily be seen from the I-75 Exit 97 interchange.
In 1962, the Kentucky Board of Education had ten construction permits to create an educational television network via a flagship station in Lexington, plus several satellite stations throughout the state. The station signed on the air on September 23, 1968 at approximately 3:00 PM Eastern time, as one of the ten charter stations of the Kentucky Educational Television network, with WKLE serving as the network flagship station. WKLE was the second educational television station to sign on; the first was WFPK-TV (now WKPC-TV) in Louisville, which signed on ten years before. All of the network’s satellites were strategically located to provide over-the-air broadcast signal coverage to much of, if not all of the state of Kentucky.
The station’s digital television companion signal, WKLE-DT, along with the digital companions of thirteen of KET’s other satellites (except WKPC and WKMJ) signed on the air in May 2002, almost three years after WKPC’s digital signal was first activated. 
Current digital channels
WKLE, along with the fourteen other principal KET satelites and three translators, multiplex their digital signals in this manner:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|46.1||720p||16:9||KET||Main KET programming / PBS|
|46.2||480i||4:3||KET2||PBS Encore / KET2|
|46.3||KET KY||Kentucky Channel|
Analog-to-Digital television transition
On April 16, 2009, WKLE shut down its analog signal, over UHF channel 46 as part of the mandatory analog-to-digital television transition of 2009. The deadline was moved from February 17 to June 12 of that year as part of the DTV Delay Act, but all KET stations, along with CBS affiliate WKYT-TV, completed the transition on April 16. WKGB's digital signal remained on its pre-transition UHF channel 48. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 46.
Spectrum incentive auction results
As of July 2017, WKLE currently holds a construction permit to move its digital signal to UHF channel 35 as part of the network’s participation in the 2016-17 FCC Spectrum incentive auction. WKLE’s digital signal is scheduled to be reallocated to its new position in early Fall 2019. The station’s current digital frequency, on UHF channel 42, is one of the upper-mid UHF band channels (38-51) to be removed from broadcasting use, and to be made for use of wireless services.
Although the market’s principal city of Lexington is the city of license for WKLE, its legal station ID between programs originally identified itself by KET’s voiceover narrator as “Channel 46, WKLE, Lexington/Richmond, Kentucky.” Richmond is included in the legal ID due to the transmitter site of WKLE being located on the Madison County side of the Kentucky River, with Richmond being the closest city to the transmitter. A similar situation exists for two other KET stations in the system (WKOH and WKMU), and most television affiliates of Georgia Public Broadcasting that includes the city of license and the closest city to the transmitter site.
As it is with most other KET stations, WKLE’s over-the-air signal covers small parts of the same areas as those of some of KET’s other stations, including WKHA/Hazard, WKMR/Morehead, WKSO-TV/Somerset and WKON/Owenton, the latter of which is technically in the Cincinnati, Ohio market. The OTA signals of all four of the aforementioned stations and WKLE help the network cover the Lexington designated market area in its entirety; indeed, WKON’s over-the-air broadcast signal does cover some of Lexington’s northern suburbs.
All cable systems throughout the state of Kentucky carry at least the flagship KET service, a few of which also carry KET2 and the Kentucky Channel, also, especially in the areas of the immediate area served by bigger cable companies such as Charter/Spectrum. The network is also available on satellite via Dish Network and DirecTV.
