By day, WPJK is powered at 3,300 watts. But because 1580 AM is a Canadian clear channel frequency, WPJK must greatly reduce power at night to 22 watts to avoid interference to other stations.[4] Programming is also heard on 250-watt FM translatorW224DB at 92.9 MHz.[5]
The call letters were changed to WORG on May 14, 1984. On September 9, 1985 the station changed its call sign to WBLO, and on February 17, 1986 to the current WPJK.[1]
On April 8, 2017, an application was filed for a construction permit to move to a new transmitter site, increase day power to 3,300 watts and add night authorization of 22 watts. The application was accepted for filing on April 18, 2017.[7]
On September 12, 2021, WPJK relaunched as "ESPN Orangeburg" with programming from ESPN Radio, and partially simulcasting some local sports programming from WQXL1470 AM in Columbia.[9]
