 In April 1974, Group One applied for a nighttime power increase from 500 watts to 1,000 watts and a move of the transmitter site to 32 52 15 N 96 42 54 W. The Federal Communications Commission approved it in February 1975.This gave KBOX a better signal, although still not approaching that of WBAP.By 1980, FM radio was growing in dominance and the ability of KBOX to compete with a music format was waning.
