The station signed on the air on July 23, 1986 as W29AD, broadcasting on UHF channel 29. It moved to UHF channel 15 and acquired the W15AM calls on January 12, 1988. In the station's early days, it was a translator for World Harvest Television from WHME-TV in South Bend, Indiana, which is owned by LeSEA Broadcasting (now Family Broadcasting Corporation). The station eventually switched to LIN TV's Local Weather Station (LWS) format with the call sign WOWD-LP (variation on WOOD-TV). WOWD and its low-power network of repeaters aired 24-hour weather information direct from WOOD-TV's weather center. This was in an early pre-digital format comparable to the now defunct NBC Weather Plus.
