Something like the BladeRF 2.0 could probably easily do ATSC but then we're getting out of my wheelhouse of shallow knowledge.
Dunno about battery life, though!Īlso, fun fact, the pretty common RTL-SDR dongles people use for SDR projects and some cyberdeck builds are actually built around a DTV receiver, although it's a DVB-T receiver, used by Europe, and like half the world, which requires much less bandwidth than ATSC. However, if this were a Raspberry Pi project, this dual ATSC tuner actually has Pi drivers and could be used to receive the whole shebang. Unfortunately, the changeover to DTV means the TV tuner in this and other devices is now useless.
Analog television signals carried the audio separate from the video on very close-together frequencies, and analog television audio signals are functionally the same as FM radio signals, so the tuner just needs an expanded range. I believe it was pretty big in Asia, in particular, but I might be misremembering). It actually was a thing right up until the changeover to DTV in the mid 2000s (although more popular in some countries compared to others.
