During the day, hosts pay the station for time on the air and may advertise their products or services during their shows. At night, WKHB plays oldies music.

By day, WKHB transmits with 5,500 watts, but at night, to prevent interference to other stations on 620 AM, WKHB reduces power to only 50 watts. The transmitter is off Turkey Farm Road in Wendel.
