A commenter on Seattlest.com said, “As a workaround this morning, KOMO had KATU, the ABC station in Portland, send their signal up here via microwave; they are transmitting that signal, and they have the news truck at Kerry Park, and they are transmitting the local news via satellite down to Portland where they are mixing it into the KATU stream and sending it back to Seattle. That’s why KOMO was showing Portland commercials and the station ID said KATU 2 this morning.”
