18- to 49-year-olds while its share rating remained a 3 or lower. Its morning newscasts barely registered a blip in the ratings. It has consistently been one of ABC's weakest affiliates in the top-100 markets. On September 11, 2006, WOI dropped the Eyewitness News brand (which the station had used for five years) and rebranded itself as "ABC5", using a variation of the circle 7 logo shared by Citadel's other major network affiliates. Since 2007, the ABC5 Weather team, led by Chief Meteorologist Brad Edwards, has been certified by WeatheRate, an independent weather rating service, as providing, "Central Iowa's Most Accurate Forecast". Edwards was previously an on-air meteorologist for the Weather Channel. On October 8, 2010, WOI-DT became the second commercial station in Des Moines (behind WHO-DT) to launch local news into high definition. Notable former on-air staff Brynn Carman – weekend anchor and reporter; now with KRDO-TV in Colorado Springs Chris Flanagan – anchor and reporter (2004–2009); now with WFXT in Boston Rick Mitchell – meteorologist (now with KXAS-TV in Dallas) Technical information Subchannels The station's digital signal is multiplexed: Translator Analog-to-digital conversion WOI-TV shut down its analog signal, over VHF channel 5, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 59, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 5. Also, the "WOI-DT" callsign was legally transferred from the pre-transition digital television channel 59 to the post-transition digital channel 5 and the "WOI-TV" callsign from the now-defunct analog channel 5 was permanently discontinued, rare among stations which usually transferred their analog-era calls to their digital counterparts (although WHO-DT also took the same action).
