“Will an AS?? tuner stop working on a certain date if not ungraded?”
FCC is not mandating a switch over from 1.0 to 3.0 but if a station does go to 3.0 they have t0 also broadcast in 1.0 till at least 2027. Many TV’s already have 3.0 tuners and adapters are available although adapters may not give you the total 3.0 experience.
I got two different sizes of Sony Bravia TV sets. Love them.
How do I tell what version tuners they got ? One is smarter than the other.
