KRMD was originally licensed and put on the air by R. M. Dean; the call sign was derived from his initials. The original license was issued, as KRAC, on November 3, 1926, with an original power of 50 watts. The station was founded by T. B. Lanford of Shreveport. In 1959, Thomas Austin Gresham (1921–2015), a 1946 graduate of
Louisiana State University in
Baton Rouge who was born in
Buenos Aires,
Argentina, came to Shreveport to manage KRMD. He was thereafter the executor of the Lanford estate from 1978 until his retirement a decade later. While in Shreveport, Gresham served for a year on the Caddo Parish Selective Service Board and was active in
Rotary International and the
American Contract Bridge League. Earlier, he had opened radio station KLOU and was the manager and part owner of
KAOK, both in
Lake Charles, Louisiana. He was a decorated
first lieutenant with the
8th Air Force of the
United States Army Air Corps in England during
World War II. He flew twenty combat missions in
B-17 bombers. Until 2005, KRMD was "1340 The Zone" and was the only
all-sports station in the "
Ark-La-Tex". In 2005, KRMD changed its format to
news/talk, branded as "SuperTalk 1340". Former programming was a mixture of
political talk with syndicated hosts
Neal Boortz,
G. Gordon Liddy, and
Bill O'Reilly and sports talk with
Tim Brando. As of the
2006 NFL season, KRMD was the local affiliate for the
Dallas Cowboys. On December 17, 2012, KRMD returned to a sports format, branded as "Sports Talk 100.7", using the frequency of its FM translator (K264AS) in its branding. The change was part of Cumulus' rollout of the
CBS Sports Radio network on its sports stations. In 2016, KRMD rebranded as "100.7 FM & 1340 AM The Ticket". On March 9, 2020, Cumulus Media flipped KRMD and K264AS from sports to
soft AC, as "Lite Rock 100.7". KRMD ceased operations on March 14, 2025. It was one of 11 Cumulus stations to close the weekend of March 14, as part of a larger shutdown of underperforming Cumulus stations, and one of four defunct Cumulus stations to surrender their licenses that September. Translator K264AS continues to operate with a simulcast of
country music sister station
KRMD-FM. ==Translators==
