one major advantage that carrier-current stations had over their licensed counterparts was the ability to change operating frequencies to suit the needs of the moment, something that kttc did with some regularity in its early years. from its start in 1950, kttc operated at 750 khz and continued at that spot on the radio dial until late 1952. the station moved to 650 khz in early 1953, then was found at 1460 khz that fall. the station took advantage of the fact that a popular local commercial radio station, kvsp-am operating at 1460 khz, would sign-off around 7pm. kttc would then begin its evening programming on 1460 at 7pm, in effect "carrying over" kvsp's campus audience without them having to change the dial on the radio. 1954 found kttc using 3 different frequencies over the year, operating at 600 in the spring, 650 in the early fall and 655 by year's end. 655 khz then became the fixed standard to find kttc on the radio dial from early 1955 until its operational end sometime in 1960.
