It was located at 8 Baltimore Road off Church Street near the intersection of Veirs Mill Road and Rockville Pike. It was consistently the third-ranked Top 40 station in the ratings, following WPGC and WEAM. The station shifted to an oldies format in the 1990s (simulcast on FM 94.3 Warrenton), then followed by a short stint as top-40 again around 1998 in the FM dominated market.
