Here in the DC area the ATSC 3.0 and 1.0 channels look equally as bad. The ATSC 1.0 channels are bitstarved with a bunch of sub-channels. And the five ATSC 3.0 channels are all sharing the same broadcast frequency.I previously posted somewhere that OTA 3.0 and my cable look visually similar and the OTA 3.0 advantage is sound quality. Well, last night The Voice and People's Choice Awards OTA 3.0 looked noticeably clearer and better than cable.
I am using an HDHomeRun Flex 4K to access the ATSC 3.0 channels.
