Where I live (and I think that this trend is spreading wider), all the channels are packed in between 12-35. When I’m adjusting my antenna over and over again, it’s quite a pain to wait for it to go 1-10 and 35-66 or wherever it ends up.
It would be cool to have an advanced feature setting (with all warnings to beginner users not to change it) to set a minimum/maximum channel to scan.
