Probably operating at critical hours at that time. If you see the Radio-Locator coverage maps, it shows WWNL 1080 in Pittsburgh beams toward south. In northern VA, I could barely hear it and it doesn't really favor my location very much. I've gotten KDKA 1020 during mid-morning along Rt 29 south of Charlottesville, VA once, with a car radio with a listenable signal.
