Great, thanks, progress already.
From your site report for my location (added to my original post). I see that the other channels I do receive have real channels in the higher range. WFAA alone is in the lower range.
Where can I read up or go to understant the real channel vs virtual channels? how and where is that mapped?
For instance, channels 5 and 11 are virtual but the bands are in the UHF range, which explains why I can receive them.
If there is something specific (apart from the coverage link which I've already added to my first post) that I'm not telling you, please let me know.
