First atsc 3.0 station in Seattle market switches on

Sometime in the last couple of days, the Tegna station KING-TV in Seattle switched to atsc 3.0 and reworked its subchannels radically, increasing from the original two subchannels to seven, many of them in full 1080. There hasn't been any press release as of yet, and there's been nothing as to the other Tegna stations in the Pacific Northwest in Portland OR or Spokane WA. As this station group is currently being hawked for sale, I wonder if any of the other stations around the country have made the switch.

One would think some press release would be forthcoming; the station completed its frequency repack a while back, moving from uhf 48 to 25. That was a pretty radical switch requiring a new transmitter and antenna array, and it seems they went all in.
