WTKT first signed on the air on February 19, 1948, as WCMB on 960 kHz with the city of license listed as
Lemoyne, Pennsylvania. (Harrisburg Evening News, February 19, 1948, page 21) The transmitter and antenna were located on Poplar Church Road() across the river from Harrisburg, in
Wormleysburg, Pennsylvania. The studios were in Lemoyne on the second floor of the Lemoyne Theatre building in the 300 block of Market Street. WCMB was founded by Edgar T. Shepard and Edgar K. "Ed" Smith under the Rossmoyne Corporation name. Smith served as the station manager for several decades. He was a lifelong resident of Harrisburg, beginning his career at
WHP in the early 1930s. WCMB moved to 1460 kHz in 1951 after WHP moved to 580 kHz. (WHP had been on 1460 kHz for ten years after the NARBA alignment.) WHP and WCMB had no formal association until the 1990s after Dame Media purchased both stations. Rossmoyne added a television station, WCMB-TV, in 1954. It was the original channel 27 in Harrisburg.
WTPA was on channel 71 at the time, starting in July 1953. WCMB-TV was an affiliate of the
DuMont Television Network. The station failed in April 1957 (per station records) after DuMont "went dark", leaving channel 27 open for WTPA to take over on June 1, 1957. WCMB-FM (on 99.3 MHz) launched in 1965 (per station records). It is presently
WHKF. The station was purchased by Dame Media in 1997 and the land at the transmitter site was sold to its next door neighbor
Harsco. After a period of low power operation from 2001 to 2004, WTKT duplexed on the
WKBO tower at the Harrisburg water plant, a new transmitter site was constructed in Summerdale. The station signed on from this site in July 2004. ==Programming==
