I don't have anything here. Maybe someone in Las Vegas could capture one of the test stations. I'm not exactly sure of the frequencies, but one source says channels 18 and 45.

BTW, you put an extra "s" in your link. Should be:

Ron, do you have any IQ files of ATSC 3 for us to try out?

I agree with you that ATSC 3 may be met with resistance. Another big switchover would upset a lot of people, even though this may finally make DTV as dependable as analog. I've described some alternative TV encoding schemes on my blog, www.coolssdrstuff.blogspot.com,  that might work better than ATSC 3. They employ DSSS, so multiple services can share a channel, and even co-exist with analog.

Thanks for response Tom and Ron.

I'll take a crack at improving the ATSC decoder efficiency first, just
to get my feet wet with GNURadio again. Tom, are there test vectors
available for the ATSC 1.0 decoder?

Whether or not ATSC 3.0 will ever be a thing... I agree with what Ron
has said, and I don't know if it will ever succeed. But with that
said, ATSC 3.0 has a better chance in existing in NA as opposed to



It's been a while since I've looked at it, but we keep this file in our set of data:

If that doesn't work for you, I can get you a good snapshot that I've used myself just captured locally off air. We don't have a good "pure" test signal lab generated or anything, though.
