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
<http://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
DVB-T2.

Colby,
It's been a while since I've looked at it, but we keep this file
in our set of data:
http://gnuradio.org/data/atsc_ref_data_low_snr_6.4Msps.16sc
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.
