This Thursday morning at 9 is supposed to be when the major Boston TV stations will flip the switch to enable ATSC 3.0 broadcasting.

For all of its potential advantages over ATSC 1.0, including 4K resolution, the only one that matters to me is improved reception. Specifically, freedom from the multipath interference that plagues UHF signals. This relative immunity, as seen in otherwise inferior VHF signals, is made possible by borrowing the modulation technology that’s used in cellular networks.
The problem is, where are the ubiquitous and affordable NextGen TV tuners and, especially, DVR’s? Without an FCC mandate like there was for ATSC 1.0, electronics manufacturers continue to drag their feet. As soon as TiVo has an ATSC 3.0 USB dongle available, I’ll get one. If I have to buy a new TiVo, that’s okay too.
The National Association of Broadcasters has met with the FCC to voice its concern about the slow adoption of NextGen TV tuners by manufacturers.
