In May 1954, the station's transmitter power output was increased to 100,000 watts. Despite the power increase, KCMC-TV was only able to provide a grade B ("rimshot") signal in rural northern Caddo Parish and could not be seen at all in Shreveport proper. (Station advertisements did not include Caddo Parish as being part of KCMC's viewing area, even though its designated area included the neighboring Louisiana parishes of Bossier, Webster and Claiborne and the neighboring Texas counties of Cass, Marion and Harrison.)
