 Her management tenure was short-lived, and in 1971 the WRKB stations were sold to former gospel singer Bill Hefner who partnered Cabarrus County judge Robert L. Warren.Upon taking control of the stations, the operating hours of WRKB-FM were extended to 1 a.m. nightly and the stations launched a full-time country music format.Popular disc jockeys during this time were Randy Whitley, Kip Yates, Tracey Hudson, David Roberts, George Berry and Randy Turner, the latter of whom would return to the station 15 years later as Animal R. O'Boogie.
