Portland is on "the list" for HD locals but they have not been uplinked yet.
With Echo 10 about two months away from operation there's a better chance
of the Portland HD locals happening.
Keep watch for the Uplink Activity threads to see when Portland gets uplinked, it's not been too long after that when they get released to subscribers.
They come out on Wednesday mornings and the title is Uplink Activity for Wed and the week the activity is for. They're usually a sticky thread at the top of the Dish Network forum.
Even those of us that already get OTA locals in HD through a separate antenna are anxious for Dish to offer them as well. It means we can record 2 HD locals at the same time or record 1 and watch 1, which is currently not possible with just an OTA antenna.
Count me as another in PDX who hopes that we're next on the list.
