History KVIL's beginnings On August 14, 1961, KVIL-FM first signed on the air, as the FM sister station to KVIL (then at 1150 AM, now KBDT at 1160 AM). Because the AM station was a daytime only station, KVIL-FM was used to simulcast the AM's personality middle of the road music format around the clock. The original location of the studios was in the Highland Park Village Shopping Center (hence the VIL call letters). The address was 4152 Mockingbird Lane at Preston Road, overlooking the Dallas Country Club golf course. In 1962 the owner/manager was John Coyle with the program director being Dillard Carerra. The station had an unusually high power of 119,000 watts in full stereo. (The power has since been reduced to 99,000 watts, because the antenna height was increased.) The engineering of the audio was routed through a huge audio mixer with slider controls utilizing German silver rheostats. Audio phasing was a problem at that time. Capitol Records, for instance, used a reverse-phasing that prevented anything recorded by The Beatles to be played, unless it was monaural. The reverse phasing simply blanked out the audio tracks to a distorted muffle. "The singing time clock" was one of the first digital breakthroughs – actually a marriage of digital and analog technology. The clock audio was recorded on 1/4" tape in stereo played on AMPEX recorders in individual segments, by the jingle singers at PAMS in Dallas. The project was huge, involving musicians, singers, and recording engineers who taped every minute on the 24-hour clock in at least two versions, to be played by the station at the appropriate
