Hardware Model HDFX-2US
Firmware Version 20260326
Device ID 10954807

A few weeks ago, list of channels that I can watch went from 100 to 21, and it's a weird mix.

For example, I scanned WBBM-DT3 on 2.3, but not WBBM-DT or DT2

Nothing on the hardware side has changed; it's an antenna in the attic ...
