WKAG-CA was a Class A low power television station in Hopkinsville, Kentucky, broadcasting locally on air as channel 43. WKAG was also on cable on NewWave Communications in Christian and Muhlenburg counties in Kentucky and on CDE Lightband in Montgomery County (Clarksville), Tennessee. The station was owned by NewWave Communications.
Founded December 9, 1983, the station went on the air in July 1984 as W43AG under the ownership of the publisher of the Kentucky New Era newspaper. The call letters were changed to WKAG-LP in 1994 (after the Federal Communications Commission (FCC) allowed low-power stations to use traditional call signs with an "-LP" suffix, instead of a translator-style call sign), and to WKAG-CA in 2002 (reflecting its Class A status).
The New Era sold the station to Owen Broadcasting, controlled by station manager Eddie Owen, in mid-2004; in 2010, NewWave purchased the station from Owen and rebranded the station as "Source16", after the station's new cable slot (before the acquisition, WKAG was instead seen on cable channel 3).
At one point during the mid and late 1990s and early 2000s, WKAG-CA has also broadcast select SEC Football and Basketball games produced and syndicated by Jefferson Pilot Sports.  In addition, WKAG also aired programming related to the Kentucky Wildcats from the UK IMG Sports Network.
For most of its history, WKAG produced local newscasts; these were discontinued on August 5, 2011, amid uncertainty about its future (the station is not included in the sale of NewWave's area cable systems to Time Warner Cable). It still rebroadcast news programming from Lexington's WKYT-TV.
On Friday, August 5, 2011, at 3 pm, Source16 employees were informed that the station would be shut down. No warning was given to employees prior to the shutdown. On September 14, 2012, due to the station having been off the air for more than twelve months, the FCC cancelled the station's license and deleted the WKAG-CA call sign from its database.
