In 1957, WJAC applied to move to 850 kHz and increase power from 500 to 10,000 watts. At the same time Saint Francis College (now Saint Francis University) in Johnstown applied to build a new station on 1400 kHz once that frequency was vacated. WJAC's move to 850 kHz, and the establishment of the new Saint Francis station, WWSF (now WYUP), was completed in 1963. However, in contrast to the single tower non-directional antenna used on 1400 kHz, operation on 850 kHz required constructing a large and complicated nine-tower directional array, sited on in Paint Township, Somerset County, Pennsylvania.
