I’ll be surprised if they leave 8.4 empty very long as that is valuable ad space. There are many diginets not available in Portland. The comment on Estrella not being what “fits” on there makes sense, as Justice & Qwest I can see “connected” type channels and Estrella being a Spanish Entertainment channel.
Here is one reason why KGW drop Spanish network Estrella TV.
Last year LBI Media/Liberman Broadcasting filed bankruptcy under the heavy debt burden of over $500 million. A reorganization plan sees the company reducing debt by more than half but a portion of ownership being handed to creditors. The stations and Estrella TV network are expected to continue to operate post-bankruptcy.
