I have lost one of my local channels - KIRO 7 (CBS), out of Seattle. Prior to installing the latest HDHomeRun firmware update today, I received KIRO without any issues. I live in Olympia, which has a local transmitter for KIRO about 3 miles from my home. It should be the easiest channel to pickup.
My configuration is a Channel Master 4228HD, long range, over-the-air antenna, professionally installed with an 11.5 foot mast on my second story roof, an HDHomeRun Quatro, and Channels version 3.2.7 software running on an Apple TV 4 with tvOS 12.0.1. I’ve re-run the channel scan multiple times without any luck. The other local network channels come in fine, even though they are much further away. For example, I am getting KOMO 4 (ABC), KING 5 (NBC), and KCPQ 13 (FOX) which transmit from 50 miles away. Again, it worked flawlessly until I updated the HDHomeRun firmware today.

Any ideas on how to solve or troubleshoot this would be greatly appreciated. I’ve tried everything I can think of.
