<p>Here's the link for libatsc3. But the main repo
<a class="moz-txt-link-freetext" href="https://github.com/jjustman/libatsc3">https://github.com/jjustman/libatsc3</a> is 404 right now.</p>

You were going to be one of the first persons I brought up, and
now I have a much more complete list of your work. <br>

<p>I hope you haven't forgotten about my ATSC 3.0
transmitter open source implementation.</p>

<p>It's an almost complete implementation of the PHY layer
and can be used to transmit Transport Streams. It does not
implement the ROUTE/DASH higher layers.</p>
<p>Here's a demo clip where I back off the power to find the
minimum required SNR (2 to 3 dB for 9/15 QPSK).<br>

<p>There was an open source receiver repository (libatsc3)
for the upper layers, but it's been deleted. I just
e-mailed the author to find out what's going on.<br>
</p>
<p>Despite getting some press for my transmitter in TV
Technology and IEEE Broadcast Technology Magazine, I've
never received any feedback.</p>

<p>The ATSC 3.0 roll out is in a bit of turmoil right now
due to broadcasters applying encryption/DRM to their
channels. The most popular STB style receivers are not
capable of decryption and consumers are being
disenfranchised. A couple thousand complaints have been
filed with the FCC.</p>

<p>Hopefully, that link works. If it doesn't, use the link
below and search for the 16-142 proceeding.</p>

<p>There's also been videos on some YouTube channels.</p>

</p>
<p>Since there's no reduced bandwidth option for ATSC 3.0,
it's not very ham friendly. Folks are reluctant to fire up
full 6 MHz wide signals, especially on 70 cm.<br>

ATSC committee leadership about open source

There's a clear difference between DVB and ATSC in ease
of use for open source work. ATSC folks are interested
in hearing more about how things can improve.<br>
<br>
If you can help with this effort, please get in touch so
we can put our best effort forward in communicating with
ATSC. <br>
<br>
If you know of someone that would be a positive addition
to the discussion, please forward this and let me know
how to get in touch with them. <br>
