Owned by Gray Media, the station maintains studios on Black Gold Boulevard off the KY 15 bypass in Hazard, and its transmitter is located south of the city in the Perry County community of Viper.

Although identifying as a separate station in its own right, WYMT is actually considered a semi-satellite of WKYT-TV (channel 27) in Lexington.

The station began broadcasting on analog UHF channel 57 as WKYH-TV (meaning "Kentucky, Hazard") on October 20, 1969.

[2]: 303  Initially, WKYH maintained studios in downtown Hazard, and transmitted its signal from a tower located at the headquarters of the local cable system.

[2]: 303 Prior to its inception, some counties in southeastern Kentucky were among the last remaining parts of the country unable to clearly receive a commercial television signal over the air.

Lexington was an all-UHF market, and UHF stations don't get good reception in rugged terrain even in the best conditions.

[2]: 304  These shows lasted well into the 1980s (in the case of the Goins Brothers, as late as 1994) after country-music programs had fallen out of favor even on other Southern stations.

[2]: 304  The repairs were not enough to keep the station's signal from deteriorating to the point of unacceptability; by 1981 it barely reached areas outside of Hazard's city limits.

Station engineers were forced to rely on microwave links from WLEX-TV in Lexington and WCYB-TV in Bristol, Virginia (from the Tri-Cities market), for network programming.

In June 1985, Gorman sold the station to Bluegrass Broadcasting, a unit of Kentucky Central Insurance Company, then owner of WKYT, for an estimated $1 million.

[2]: 304 [8] After approval of the sale, the new owners changed the calls on the morning of Saturday, October 19 of that year to the current WYMT, meaning "We're Your Mountain Television".

[9] The old WKYH callsign now exists on a Paintsville-licensed AM radio station in nearby Johnson County which, incidentally, launched in 1985 as WKLW.

DirecTV and Dish Network argued it would be technically and economically infeasible, as they would be required to create a new spot beam for this particular area, and cited their right to refuse carriage.

[14] From 2014 to 2019, WYMT-DT2 served as the local home of Raycom's ACC Network, the syndicated package of Atlantic Coast Conference football and basketball.

[18] The station's signal is multiplexed: WYMT-TV shut down its analog signal, over UHF channel 57, on February 17, 2009, the original target date on 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 easternmost counties (Pike, Floyd, Martin, Johnson, and Lawrence) are in the Huntington–Charleston, West Virginia market (home territory for sister station and NBC affiliate WSAZ-TV).
